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 productionâdesign, 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.

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.

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 boardâcutting 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.

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.
