How to Choose Professional PCB Prototype Assembler

December 10th, 2019

OEMs, especially those requiring only a few boards to be assembled, may want to outsource their Printed circuit boards to a professional PCB prototype assembler, rather than assemble the boards in-house. Instead of investing in expensive production equipment, they would prefer to obtain their product from a PCB prototype manufacturer, and have an expert assemble it, so that they have reliable PCBs. Fortunately, an eminent enterprise, Best Technology, provides expert solutions for both manufacturing and assembling PCBs.

Turnkey PCBA Services
Turnkey PCBA services


OEMs are experts in the products they manufacture, but may not be so knowledgeable about the PCBs and assemblies that make up their product. Therefore, some guidelines are necessary to enable them select the professional PCB prototype assembler most suited to their requirements.
Technical Expertise
It is very important to ensure the assembler has the necessary processes in place. For instance, if the OEM requires BGAs on their PCB, they must ensure the assembler is capable of BGA assembly and rework, and they have X-ray machines for verifying their assembly. As most PCBs use surface mount devices, the assembler should be familiar with them to the extent of using automated machinery for SMT assembly.
Working Closely
If the OEM is outsourcing for prototype manufacturing and assembly, it is important that the assembler be willing to work with them for fixing errors in the layout, mistakes in the BOM, and parts that do not match the footprints on the board. The OEM should be able to make the most of the existing board while resolving the problems with the assembler.
Objective of the Outsourcing
To be effective, OEMs must also set their objectives that they expect from the outsourcing partner. This is important, as the objectives may vary. For instance, some may be planning to outsource a single product, others may be shifting their growing volumes to a partner with a higher production capacity, while still others may be looking for reducing costs.
Request for Quotation

When the OEM sends an RFQ or request for quotation to a PCB prototype assembler, it is important they provide all the commercial and technical information the assembler would need. This holds true even when the OEM is looking for a potential PCB prototype manufacturer.
Management Aspects
To ensure smooth working with the prototype assembler, it will be advantageous to the OEM if they periodically audit their partner, making sure the team has as wide range skills as possible. If necessary, the OEM can transfer some of their skills and knowledge to their partner. A good management practice is to establish regular meetings to make sure activities move on schedule, and the relationship can be discussed at higher levels, while the OEM outlines their strategic plans for the future.
Conclusion
Best Technology, both a professional PCB prototype manufacturer and a PCB prototype assembler, can handle not only prototype jobs, but also take up regular production works and turnkey projects. It meets all the above criteria, has the necessary quality management systems in place, and has the necessary technology and expertise to handle the most complicated board assemblies.

Difference between A Double Sided MCPCB and a Double Layer MCPCB

November 25th, 2019

Metal core printed circuit boards(mcpcb) are suitable alternatives for FR4/CEM1-3 variants. These circuit boards use metal as a core base material and are differentiated on the basis of their construction. There are a few types such as single layer, double layer, double sided, and multi-layer PCBs. What are heavily used in advanced electronic circuits are the double layer and double sided metal core printed circuit boards. These two types arise confusion due to their similar names. What are the differences between both? What advantages do they offer? Now you can get the answer from the following description.

Definition of a Double Sided and Double Layer MCPCB:

The double sided MCPCB and double layered MCPCB have different layout, due to the positioning of a metal core:

In a double sided MCPCB, the metal core lies in the middle of two conductor layers. There is also a dielectric layer between the metal core and a copper layer. The metal core and conductors are connected to each other through Vias. The SMD can be populated at the bottom and top.

A double layer MCPCB has a metal core at the bottom, with two conductor layers on its top. In short, the conductor layers lie in same side of the metal core. Generally, metals like aluminum, copper, and iron alloys are used as metal cores. The dielectric layer lies between a copper layer, and the bottom metal core. The SMD can only be populated on the top.

Advantages of Double Sided MCPCB and Double Layer MCPCBs:

Both these variants offer the same benefits as other metal core PCBs. They are as follows:

Reliable Performance at High Temperatures: Many double sided CEM3 or FR4 PCBs with high power and density face difficulties in heat dissipation. The CEM3 or FR4 material have weak thermal conductivity, which means the electronic components are destroyed at high temperatures. However, double sided metal core circuit boards feature a metal core, which has an excellent inter-layer insulation and thermal conductivity. Both these factors contribute to its reliable performance at high temperature.

Excellent Thermal Expansibility: Thermal expansion and contraction is an important feature of all objects. The ability to contract with cold, and expand with heat is termed as coefficient of thermal expansion. Most FR4 PCBs have low CTE, which means they cannot effectively deal with issues of contraction and expansion. However, both double sided and double layer PCBs can effectively deal with thermal expansibility. Thus, they are in demand.

Applications of Double Sided MCPCB and Double Layer MCPCBs:

LED lights

Street and general lighting

Industrial controls

Power monitoring devices

Automotive

Amplifiers

Test equipment

The choice of the either type will depend on your application requirements. If you are still confused about the two types and their benefits for your application, you can always approach an industry expert or a reliable metal core pcbs manufacturer like Best Technology, which provides different types of MCPCBs in diverse specifications.

How to Choose a Professional PCB Assembly Company

November 18th, 2019

Hardware designers requiring turnkey PCB assembly services usually face tremendous obstacles for their need of prototyping and small batches. Large companies with huge inventory needs and long delivery horizons can wait for days or weeks for a proposal, while accepting large minimum quantity requirements. For them, delays associated with overseas manufacturing are no big deal. However, these conditions are simply unacceptable for small industries, engineers, makers, and entrepreneurs.

Best Practices of PCB Assembly Vendor

Selecting the professional PCB assembly company at the beginning determines the success of a project. Therefore, picking the right PCB assembly services provider becomes a highly important decision to be made. One must watch out for those offering very low prices, but subsequently are unable to provide the services, record of accomplishment, infrastructure, and technology to back up their promises. Rather, one must insist the PCB assembly services have the essential features, offer the services, and follow business practices such as:

Instant Quotations

Waiting for days or weeks and trading a bunch of emails only to find out the cost of a PCB assembly, is not only a waste of time, it is expensive. A vendor offering instant, online quotations is always preferable. In general, although all vendors will start by sending a quotation for the project, therefore, selecting one who gets the process off painlessly is advisable. Moreover, selecting the vendor who gives an estimate in terms of quantity offtake helps in determining capital needs and product prices.

Prototyping Requirements

Most customers, before placing their order, want to make sure their PCB works exactly as intended. This may require making a few iterations to perfect the design. So far, prototyping was a big challenge under the old manufacturing model. However, Best Technology is willing to handle even a single quantity.

Minimum Order Requirements

Earlier, PCB assembly services were unable to accept production runs of small quantities. Older technology did not allow profitability in smaller numbers, which turned out to be a major challenge for everyone. However, use of modern technologies allows easy combination of small orders into larger ones, while switching from one task to another is no longer a major hurdle. Therefore, professional PCB assembly providers accept all types of order, regardless of quantity, and execute them at reasonable prices.

Seamless Manufacturing

With advancement in PCB assembly technologies, it is no longer necessary to track multiple vendors and suffer long lead times. A modern PCB assembly solution such as the Best Technology, offers a platform to resolve any assembly problems, online and from anywhere and takes over the sourcing, purchasing, and assembly of the components. With this approach, the product can be expected to be available in days.

Looking Beyond PCB Assembly

The PCB happens to be only the first step of the many for most inventions and products and PCB Assembly is an especially non-negligible process. Quality can only be assured by finding a reliable company.

LED Lighting: MC-PCBs

November 13th, 2019

LEDs are pretty hot nowadays! Not just the biggest tendency in lighting, but also require a lot of heat dissipation that standard PCB material just can’t handle. So what’s the solution? Metal PCBs. Standard PCB material typically has a thermal conductivity of 0.5 W/m K; which is not adequate for the current high intensity LEDs. With MCPCB materials you can increase the life of your LEDs with better heat dissipation.

What’s the thermal conductivity of MCPCB material?

Up to now, Best Technology has helped many customers with their MCPCB needs and have found the most common questions as shown below:

What is the most cost effective MCPCB?

How do you layout an MCPCB?

Can I get a different dielectric thickness between the metal and circuit layer?

Can I put plated through holes on an MCPCB?

Can I do more than one layer with an MCPCB?

How quick can a MCPCB be manufactured?

What Metals can be used?

The professional staff at Best Technology can help you resolve these questions and even more. Need help getting started? Contact us today.

PCB Assembly Fabrication Methods

November 12th, 2019

PCB or Printed Circuit Board assembly at Best Technology involves combining the bare PCB, electronic components, and other accessories effectively to allow the assembly to function as the designer intended. Generally speaking, the fabrication methods involve a number of major steps:

(1)Component placement

(2)Soldering

(3)Cleaning

(4)Inspection

(5)Testing

Component Placement

Methods of placing components on the PCB rely on several factors such as:

Single or double side component placement

SMD components only

Through-hole (TH) components only

Mix of SMD and through-hole components

A PCB may have components present only on one of its sides or on both, although assembling a PCB with through-hole components on both sides is a rare occurrence. Single side component placement with either all SMDs or all through-hole components is more common, while single sided PCBs with a mix of SMDs and through-hole components is also to be found.

For assemblies requiring SMDs on both sides of the PCB or a mix of SMD and through-hole components on the top and only SMDs on the bottom, the PCB assembly process must be broken up into several intermediate steps, and the assembler needs to take special precautions for each of them.

Soldering

Soldering is the process of joining two dissimilar metals using a molten filler metal alloy. The molten metal alloy enters the joint, and as it cools and solidifies, bonds with the adjoining metals. Primarily,  three common ways of soldering including manual soldering, wave soldering and reflow soldering are available.

Cleaning

After soldering is over, some flux residue may remain on the printed circuit board. Over time, this can turn acidic, and corrosively damage solder joints. The flux residue can also attract fingerprints and make the PCB look unclean.

Manual Inspection

Inspection is necessary at various stages of assembly. For instance, one stage of inspection is necessary when the operator has stuffed TH components into the board, and again once the assembly has undergone wave soldering.

Similarly, for reflow soldering, inspection is necessary once after solder paste printing is over, then again after mounting the SMD components, and once again after the boards have exited the reflow oven.

AOI & X-Ray Inspection

For large batches of PCB assembly, the manual inspection process may be too slow. A faster process is the Automatic Optical Inspection or AOI process. AOI machines have video cameras to capture images of the PCB, the components, and the solder quality, and they can compare the images with standard images in the machine’s memory. The AOI machines work at high speed processing a large number of PCBs within a relatively short time.

Electrical & Functional Testing

Electrical testing may be necessary after the assembly has passed through the above stages, to test whether the assembly functions as intended by the designer. This may involve programming the board, or calibrating certain components before the actual testing can begin.

Electrical and functional testing involves applying specific voltage/voltages to the circuit on the PCB and looking for normal/abnormal behavior at predefined outputs. Some tests may require a voltmeter and ammeter, while others may need more sophisticated instruments such as an oscilloscope or a waveform analyzer to complete the testing.

Conclusion

PCB assembly is a complicated process involving several technical processes with important setup parameters. Eminent assemblers such as Best Technology are always careful with these setup parameters to allow the final product achieve the desired quality.

The Basics of Printed Circuit Board Assembly(SMT)

November 1st, 2019

Printed circuit board assembly(SMT), also known as “stuffing†or “populatingâ€Â the bare printed circuit board, is quite an intricate process which involves many different stages.  Best Technology’ in house printed circuit board assembly service makes ordering your turnkey printed circuit boards a hassle-free experience as you can count on the industry’s largest support team to help you control every step of the process.

Here are some of the basic elements involved in the printed circuit board assembly process:

Solder Paste Ã¢â‚¬â€œ Solder paste is a combination of flux, a chemical created to assist in the bonding and melting of the metal, and small fragments of metal (solder) so as to apply the electronic components to the printed circuit board. The paste is placed on the board in specific places along the board in exact amounts with the use of a Solder Stencil and a paste application machine, automatically.

Pick and Place Machine – This machine is essential in an automated printed circuit board assembly process.  The machine is programmed to automatically coordinate with complete accuracy the places to precisely mount each electronic component to be soldered to the printed circuit board. These machines are exact and quick.

Infrared Reflow Ã¢â‚¬â€œ After the precise bonding element (solder paste) is applied to the PCB, the board will be directed to the reflow oven to join the electronic components to the board by melting the solder paste. This “oven†is comprised of many heaters whose main function is to heat the board to a precise temperature and control the level of cooldown as the solder hardens. This process is crucial to the creation of properly functioning electronics. The printed circuit board will run through a series of testing to ensure no issues or short-circuiting nor misalignments have occurred.
