What is Through Hole Technology in PCB? Through Hole Technology vs. SMT
Monday, June 9th, 2025

At Best Technology, we offer both SMT and through-hole assembly for various PCB types. With ISO certifications, our team guarantees precise quality and traceability. Whether you’re working on PCB prototypes or large-volume orders, we can handle the complete process—from PCB fabrication to full assembly—with competitive pricing and professional engineering support.

What Is Through-Hole Technology?

Through hole technology is a method used to mount electronic components on a printed circuit board (PCB). It involves drilling holes in the PCB where component leads are inserted and soldered to pads on the opposite side. This process creates a strong mechanical bond, which is especially useful for components that handle higher currents or need more stability.

The term PCB through hole refers to those drilled spaces where leads pass through and connect circuits on different layers. Although newer surface-mount technology (SMT) is now more common, through-hole is still widely used in specific applications such as aerospace, military, and testing environments.

What Are the Characteristics of Through-Hole Technology?

Through-hole technology has a few defining features that separate it from SMT. First, it requires precise drilling into the PCB, which can add time and cost to production. Second, it uses leaded components, meaning parts have metal wires that must be placed through the holes. Third, the soldering can be done manually or by wave soldering, depending on the complexity and quantity of the assembly.

Another key trait is the mechanical strength of the joint. Unlike SMT components, through-hole parts have deeper anchoring, making them more reliable under stress, vibration, or high temperature.

Different Types of Through Holes

There are several types of PCB through holes, each serving different purposes in the assembly process:

1. Plated Through Holes (PTH)

These are the most common. They have conductive copper plating inside the hole walls, creating electrical connections between layers of the PCB. PTHs are used for both signal routing and mounting components.

2. Non-Plated Through Holes (NPTH)

These holes have no copper inside and are used purely for mechanical reasons—such as mounting screws or hardware. They don’t connect circuits or carry current.

3. Via Holes

Though often grouped separately, vias are also a type of through hole. They connect one PCB layer to another electrically but are not used for inserting components. Vias can be through vias, blind vias, or buried vias depending on the layers they connect.

4. Component Holes

These are drilled specifically for component leads like resistors, capacitors, and connectors. They’re usually PTHs because they need both electrical connectivity and physical anchoring.

What Is the Difference Between SMT and Through-Hole Technology?

The key difference lies in how components are mounted onto the PCB:

FeatureThrough-Hole TechnologySurface Mount Technology (SMT)
Component PlacementLeads inserted through drilled holesMounted directly on PCB surface
Board Sides UsedBoth sides (top for components, bottom for solder)Mostly one side
Assembly TypeManual or wave solderingAutomated solder reflow
Mechanical StrengthHighModerate
Suitable ForHigh-stress environmentsHigh-density, lightweight electronics
CostHigher due to drilling and manual laborLower with automated production

In short, through-hole technology vs SMT often comes down to reliability vs efficiency. SMT is ideal for modern, compact devices, while through-hole is preferred for heavy-duty or high-reliability circuits.

What Are the Advantages of Through-Hole?

  • ‌Strong mechanical connection: Through-holes provide a strong mechanical connection by welding the pins of components onto the PCB, suitable for withstanding large mechanical stress.
  • ‌Mature manufacturing process: The manufacturing process of through-holes is relatively mature, with low cost, and suitable for large-scale production.
  • ‌High compatibility: Through-hole PCBs have good compatibility with the packaging forms of components, suitable for traditional through-hole packaging and larger-sized, special-shaped components.
  • For manual soldering and maintenance: Through-hole PCBs are convenient for manual soldering and maintenance, and can be completed with ordinary soldering irons and other tools.
  • Higher Current Capacity: Larger leads and deeper solder joints handle more power.
  • Reliable for Prototyping: Easier to work with manually, which helps in R&D.

Disadvantages of Through-Hole Technology

While useful in many cases, through-hole also comes with limitations:

  • More Expensive: Drilling adds manufacturing time and cost.
  • Lower Component Density: Takes more space on the PCB compared to SMT.
  • Slower Assembly: Manual or wave soldering is not as fast as automated SMT.
  • Double-Sided Processing: Components on one side, solder on the other, complicating rework or inspection.
  • Affects Signal Integrity: In high-speed signal transmission, through-holes will generate parasitic capacitance and inductance, which may cause signal delay and crosstalk, affecting signal integrity.

These drawbacks make through-hole less suitable for modern high-volume or miniaturized electronics.

What Materials Are Used in Through Hole Technology?

The materials involved in through-hole assembly include:

  • PCB Substrate: Usually FR-4, a flame-retardant fiberglass material.
  • Copper Foil: Used for plating the walls of the hole to make electrical connections.
  • Solder: Commonly a tin-lead alloy or lead-free alternatives for RoHS compliance.
  • Flux: Helps the solder flow and bond to the metal surfaces.
  • Leaded Components: With metal leads or wires that go through the board.
  • Masking Ink: Protects areas not intended for soldering.

These materials work together to create strong, conductive joints that last over time.

Considerations During Solder Through Hole Components

When soldering through-hole components, keeping the following factors in mind helps ensure a reliable and high-quality connection:

1. Hole and Lead Size Matching

    The drilled hole must closely match the component lead diameter. Too loose causes weak joints; too tight restricts solder flow.

    2. Proper Soldering Method

    • Manual soldering is ideal for prototypes or low-volume assemblies.
    • Wave soldering suits larger batches with consistent quality and speed.

    3. Controlled Flux Application

    Apply just enough flux to clean surfaces and improve solder flow. Excess flux may leave residues or cause corrosion.

    4. Accurate Component Placement

    Leads should be inserted straight and fully into the hole to avoid stress during soldering or later use.

    5. Correct Soldering Temperature and Time

    Maintain proper heat levels and dwell time to prevent cold solder joints or overheating.

    6. Avoiding Solder Bridges

    Ensure solder doesn’t accidentally connect two adjacent pads or leads, especially in tight areas.

    7. Mechanical Stability

    For connectors or large components, use support fixtures during soldering to keep parts from shifting.

    8. Inspection After Soldering

    Visually check for smooth, shiny solder joints. Use magnification or x-ray for dense or complex boards.

    9. Post-Solder Cleaning

    Remove any leftover flux residues with appropriate solvents or cleaning processes to prevent long-term damage.

    10. ESD Safety Measures

      Handle components with ESD precautions to protect sensitive devices from electrostatic discharge during assembly.

      What Is a Through-Hole Used For?

      Through-holes are used in many areas of PCB manufacturing and assembly. Their main function is to:

      • Mount Large Components: Like capacitors, connectors, or inductors.
      • Transfer Signals or Power: Across multiple layers of the PCB.
      • Anchor Parts: Where strong mechanical support is necessary.
      • Support Prototyping: Breadboards and experimental PCBs often use through-hole components because they’re easier to insert and replace.
      • Handle Harsh Conditions: Ideal for products exposed to motion, heat, or heavy-duty usage.

      In short, PCB through hole designs are a practical solution when strength, reliability, and repairability are key.

      FAQs

      1. Is through-hole technology still used today?

      Yes, especially in aerospace, automotive, and high-power applications where strength and reliability are crucial.

      2. Can through-hole and SMT be used on the same PCB?

      Yes. Mixed technology boards combine both methods to meet different design requirements.

      3. Why is through-hole better for testing?

      Leaded components are easier to probe and replace, which helps during R&D or repair.

      4. Is through-hole more expensive than SMT?

      Generally, yes—due to manual labor, hole drilling, and larger component size.

      5. Which is better: SMT or through-hole?

      It depends. SMT is better for compact, automated designs. Through-hole is better for strength and harsh environments.

      Printed Circuit Board Assembly PCBA, Short Delivery

      What is a Printed Circuit Board Assembly PCBA?

      A printed circuit board assembly, or PCBA, refers to a finished circuit board after all the electronic components are mounted. This includes resistors, ICs, capacitors, and connectors. The PCBA stage transforms a bare PCB into a functional board ready to be used in devices.

      Printed Circuit Board Assembly PCBA

      What is the Difference Between PCB and Printed Circuit Board Assembly PCBA?

      PCB is the blank board made of layers of insulating material and copper traces. It serves as the backbone of electronics. A PCBA, on the other hand, is that same board but fully populated with components. Simply put, PCBA = PCB + Assembly Process.

      How Does a Printed Circuit Board Assembly PCBA Work?

      The process begins with placing solder paste on pads, then mounting components using SMT or manual insertion. After that, boards are passed through a reflow or wave soldering process. Testing and cleaning ensure quality before packaging. At Best Technology, this process is handled quickly, even within 24–72 hours.

      What Is a Cold Solder Joint and How Do You Prevent It?
      Thursday, May 29th, 2025

      When a cold solder joint appears on a PCB, it might not fail immediately. But over time, it can cause real trouble—intermittent signals, unstable connections, or even complete circuit failure. These defects are often hidden, and if not caught early, they can waste time and money in rework.

      In this blog, you’ll learn:

      • What a cold solder joint looks like
      • What causes it
      • How to avoid and fix it
      • Why a trusted PCB assembly partner like Best Technology matters

      What is a Cold Solder Joint?​

      A cold solder joint or cold joint solder, is a defective connection between a component lead or terminal and a PCB pad during PCB assembly process. Unlike a properly formed solder joint, which provides a strong, reliable electrical and mechanical connection, a cold solder joint fails to fully bond the two elements together.​

      When soldering is done correctly, the solder melts completely and wets both the component lead and the PCB pad, creating a smooth, shiny, and concave surface. In the case of a cold solder joint, however, the solder doesn’t reach its optimal melting point or doesn’t flow properly. This results in a rough, dull, and often uneven surface. The joint may look like it’s attached, but in reality, the connection is weak and prone to failure. It might conduct electricity intermittently or not at all, leading to erratic behavior in the electronic device, from occasional glitches to complete breakdowns.​

      What Is a Cold Solder Joint and How Do You Prevent It?

      Cold Solder Joint Causes​

      Several factors can contribute to the formation of cold solder joints. Understanding these causes is the first step in preventing them.​

      What Is a Cold Solder Joint and How Do You Prevent It?
      • Inadequate Soldering Temperature​

      One of the primary culprits is insufficient soldering temperature. Each type of solder has a specific melting range, and if the soldering iron or reflow oven doesn’t reach and maintain the appropriate temperature, the solder won’t melt fully. For example, if the temperature is too low, the solder may only partially liquefy, leaving solid particles that prevent a proper bond.

      • Incorrect Soldering Time​

      If the soldering iron is applied for too short a time, the solder won’t have enough time to melt and flow properly. On the flip side, overheating the joint by leaving the soldering iron on for too long can also cause problems. It can damage the component leads, PCB pads, or even change the properties of the solder itself, potentially leading to a cold solder joint.​

      • Poor Surface Preparation​

      The cleanliness and condition of the surfaces to be soldered are vital. If the component leads or PCB pads are dirty, oxidized, or contaminated with oils, residues, or other substances, the solder won’t adhere properly. Oxidation, in particular, forms a thin layer on the metal surfaces that acts as a barrier to soldering.

      • Inappropriate Flux Usage​

      Flux is a key component in the soldering process. It helps clean the surfaces, remove oxidation, and promote the flow of solder. However, using the wrong type of flux, too little flux, or applying it incorrectly can lead to cold solder joints. Some fluxes may not be compatible with certain solders or components, while insufficient flux won’t provide enough cleaning and wetting action.

      • Component Movement During Soldering​

      When components move while the solder is still molten, it can disrupt the formation of a proper joint. This can happen due to vibrations during the soldering process, improper handling of the PCB, or insufficient securing of the components. Even a small movement can break the developing bond, resulting in a cold solder joint or a weak connection.​

      Cold Solder Joint Pictures​

      Visual aids can be extremely helpful in identifying cold solder joints. Here are common visual signs:

      • Dull, Grainy Appearance: A good joint is shiny and smooth. Cold ones look frosty or matte.
      • Cracks or Gaps: Visible separations or voids between the component and pad.
      • Ball-Like Shape: If the solder beads up instead of flowing smoothly, it likely didn’t bond.
      • Lifting Leads: Components that seem slightly off the pad may signal a cold joint underneath.

      Below are some typical colder solder joint pictures examples:​

      How to Identify Good Solder Joint​?

      Identifying a good solder joint is just as important as recognizing a cold one. A high-quality solder joint has several distinct characteristics:​

      1. Appearance​

        A good solder joint should have a smooth, shiny, and concave surface. The solder should flow evenly around the component lead and onto the PCB pad, forming a natural fillet.

        2. Wetting​

        Proper wetting is a key indicator of a good solder joint. The solder should spread and adhere evenly to both the component lead and the PCB pad, covering the surfaces completely. When the wetting is correct, there will be no gaps, voids, or bare spots where the metal surfaces are exposed.

        3. Strength​

        A well-soldered joint should be strong enough to hold the component in place firmly. Gently tugging on the component (with appropriate care not to damage it) should reveal a solid connection.

        How to Avoid Cold Solder Joints​?

        Prevention is better than repair. Here’s how to keep cold solder joints from happening in the first place:

        1. Use the Right Temperature

        Always set your soldering iron between 350°C to 400°C for standard lead-based solder. Higher temperatures may be needed for lead-free types.

        2. Pre-Clean Pads and Leads

        Use isopropyl alcohol to clean surfaces before soldering. Dirt and oxidation are invisible enemies.

        3. Don’t Skip the Flux

        Flux removes oxidation and improves solder flow. Many solder wires include it, but extra flux helps in difficult spots.

        4. Keep Steady Hands

        Hold the component and iron steady until the solder cools. Use clamps or tools if needed.

        5. Pick Quality Tools

        Poor-quality irons with unstable tips lead to inconsistent heat. Invest in a reliable soldering station with temperature control.

        6. Work in a Clean, Static-Safe Area

        Humidity, static, and poor lighting all raise the chances of making mistakes.

        How to Fix Cold Solder Joints​?

        Despite our best efforts, cold solder joints may still occur. Fortunately, there are ways to fix them:​

        1. Soldering​

          The first step in fixing a cold solder joint is often desoldering. Use a desoldering pump or wick to remove the existing solder from the joint. Heat the joint with the soldering iron to remelt the solder, and then use the desoldering tool to suck up or absorb the molten solder. Make sure to remove all the old solder completely to start fresh.​

          2. Cleaning​

          After desoldering, clean the surfaces again to remove any flux residues, oxidation, or other contaminants that may have accumulated. This step is crucial for ensuring a proper repair. Use a suitable cleaning solution and a clean brush or cloth to wipe the surfaces clean.​

          3. Resoldering​

          Once the surfaces are clean, it’s time to resolder the joint. Apply a small amount of fresh flux to the cleaned surfaces, and then heat the joint with the soldering iron. When the flux starts to bubble and activate, feed a small amount of solder into the joint.

          4. Inspection and Testing​

          After resoldering, inspect the joint visually to make sure it looks good and meets the criteria for a proper solder joint. Then, use testing equipment to verify the electrical connection. Check for continuity and make sure the joint is conducting electricity properly. If any issues are found, repeat the desoldering, cleaning, and resoldering process until the joint is fixed.​

          SMT PCB Assembly Process, SMT Board Assembly, NO MOQ

          What Is SMT Board Assembly?

          SMT board assembly is the process of placing surface-mounted devices (SMDs) onto a printed circuit board (PCB). Unlike traditional through-hole methods, SMT doesn’t require drilled holes. It saves space and improves signal flow. This makes SMT the best choice for modern electronics where small size and high performance are key.

          SMT PCB Assembly Process

          Is SMD the Same as SMT?

          Not exactly. SMD refers to the components themselves—small chips that mount on a PCB. SMT is the process that places and solders those SMDs. They are closely connected but not the same. Think of SMDs as the parts, and SMT as the way they’re installed. When both work smoothly, the final result is reliable.

          What Are SMT Components?

          SMT components include resistors, capacitors, ICs, LEDs, and transistors. These parts come in tiny packages that fit directly onto PCB pads. Because they are compact, they need accurate placement. Even slight misalignment can lead to defects. At Best Technology, we use high-precision machines to ensure perfect positioning.

          What Temperature Should SMT Solder Paste Be?

          Solder paste temperature must be carefully controlled. The reflow oven follows a heat profile, usually peaking between 230°C and 250°C. For lead-free solder, control is even more important. If the paste overheats, it may spatter. If too cold, cold solder joints may occur. Best Technology uses advanced ovens with stable profiles. This ensures every joint is smooth and strong.

          SMT Board Assembly, NO MOQ

          How Does SMT Board Assembly Work on a CPU?

          CPU boards need extreme accuracy. Their BGA components sit under the chip body, making inspection harder. SMT board assembly for CPUs includes paste printing, placement, reflow, and X-ray checking. Each step must be flawless. We use 3D paste inspection, AOI, and X-ray to detect any hidden issues. That’s how we keep our CPU boards reliable.

          What Is the SMT Board Assembly Process?

          Here’s a step-by-step look at how SMT board assembly works:

          1. Solder Paste Printing: Paste is applied on PCB pads with a stencil. We check for even coverage and correct alignment.
          2. Component Placement: Machines pick and place SMDs based on coordinates. Best Technology uses precise vision systems to avoid misalignment.
          3. Reflow Soldering: The PCB passes through ovens to melt the paste. This bonds components to pads. We control heat curves to avoid cold joints or bridging.
          4. Inspection: AOI checks solder and component positions. For BGAs, we use X-ray inspection to ensure there’s no tombstoning or voids.
          5. Testing: We run electrical tests and sometimes functional checks to verify the board works before delivery.

          This SMT PCB assembly process reduces human error and increases repeatability. It’s efficient and scalable.

          Why Should You Choose Best Technology as Your SMT Board Assembly Partner?

          Choosing Best Technology involves more than just high-quality SMT Board Assembly; we also provide SMT board assembly solutions.

          • Defect Control: Our AOI, X-ray, and 3D inspection systems detect short circuits, tombstones, or cold joints early.

          This process is designed to meet the strict quality expectations of today’s high-tech products.

          How long can solder paste sit before reflow?

          Solder paste shouldn’t sit too long. Generally, once it’s printed, it should be reflowed within 4 to 8 hours. Delays may cause oxidation or poor soldering. Best Technology selects various solder pastes based on the specific components and SMT technologies involved, ensuring optimal solder joint performance. Each bottle of solder paste goes through our MES system, allowing us to monitor and make sure that we are using the correct solder paste for each application.

          What is a printed circuit board assembly?

          A printed circuit board assembly (PCBA) involves mounting and soldering electronic components onto a bare PCB. The board starts as a flat piece with copper pathways. Then, components like resistors, capacitors, and microchips are placed onto the board, either by hand or automated machines. After soldering, the board is tested to ensure every part works as intended.

          Assembly is different from just PCB manufacturing. PCB manufacturing is about making the empty board. Assembly is about adding life to it. Together, they form the full process that brings electronics to life.

          Who manufactures printed circuit board assembly?

          Many companies around the world specialize in this service. In the USA, there are hundreds of printed circuit board assembly manufacturers, ranging from small custom shops to large factories. Some companies only do assembly, while others handle the full production—design, fabrication, and assembly.

          Examples include:

          • Best Technology
          • Sanmina
          • Jabil Circuit
          • Advanced Circuits
          • TTM Technologies

          Each one has its strengths. Some focus on fast prototyping. Others offer high-volume production or special certifications like ISO13485 for medical devices.

          Printed Circuit Board Assembly Manufacturer

          What is the best printed circuit board assembly manufacturer?

          There is no one-size-fits-all answer. The best printed circuit board assembly manufacturer depends on your needs. Still, you can look for certain traits:

          • Quality standards: Look for ISO9001 or IATF16949.
          • On-time delivery: A delay in boards can delay your whole project.
          • Customer service: You need a team that responds quickly and clearly.
          • Engineering support: Helpful when working on a new or custom design.
          • MES material tracking: Ensures traceability for each component used.

          Best Technology meets all of these standards and more. With a professional engineering team and MES systems in place, they help clients across medical, automotive, and industrial fields.

          No MOQ

          Who is the largest printed circuit board assembly manufacturer in the world?

          The largest printed circuit board assembly manufacturer globally is Foxconn. Known for assembling Apple products, Foxconn handles massive volumes daily. Other giants include Pegatron, Flex, and Jabil.

          But for many companies, especially small to mid-sized firms, these giants might not be the right fit. They often prefer flexible manufacturers like Best Technology, which focus on quality, service, and custom solutions rather than only volume.

          How do I find the printed circuit board assembly manufacturer?

          Finding the right manufacturer starts with research. Here’s a quick process:

          • Define your needs: Quantity, lead time, board type.
          • Check directories: Use online directories for printed circuit board assembly manufacturers USA or global lists.
          • Ask for samples: A real sample shows quality better than words.
          • Review certifications: Make sure they meet industry standards.
          • Talk to the team: Communication style tells you a lot about future service.

          Also, pay attention to reviews, turnaround times, and available services. If you’re in the USA, searching for “PCB assembly USA” or “printed circuit board assembly manufacturer California” can lead you to local options.

          What is the difference between printed circuit board assembly and PCB manufacturing?

          PCB manufacturing is the first step. It involves creating the board—cutting the shape, printing the circuit layers, and adding holes or vias. PCB assembly is what comes next. This stage involves placing and soldering components onto the manufactured board. In short:

          • PCB manufacturing = creating the board
          • PCB assembly = adding components to the board

          Some companies do both. Others specialize in one area. It helps to know what you need before you contact a supplier.

          Printed Circuit Board Assembly Manufacturer, No MOQ

          How are printed circuit board assemblies manufactured in industry?

          The process is highly automated, especially for large runs. Here’s a simplified version of the process:

          • Stencil printing: Solder paste is applied to the board using a stencil.
          • Component placement: Pick-and-place machines put parts on the board.
          • Reflow soldering: Boards go through an oven that melts the solder paste.
          • Inspection: Optical machines and X-rays inspect for issues.
          • Testing: Functionality tests ensure the board works as intended.
          • Final cleaning and packing: Boards are cleaned and packed for shipping.

          Advanced printed circuit board assembly manufacturers use MES systems to track every board from start to finish.

          Why should you choose Best Technology as your trusted printed circuit board assembly manufacturer?

          Best Technology stands out for many reasons:

          • Certifications that matter: ISO9001, ISO13485, AS9100D, and IATF16949. These cover aerospace, automotive, and medical needs.
