The pictures above is a PCBA Design for circuit board with 300m wifi router mainboard that customized and developed by SemiPCB. This circuit board is common on the market, and there are many similar products. We checked the function of the samples provided by customers, and then redesigned and developed this PCBA circuit board according to the new structural design provided by customers, which has been mass-produced hundreds of thousands of units.
Our PCBA design engineer designed this circuit board as 4 layers FR4 PCB, thickness of 1.6mm, all copper 1oz, green solder mask, white silk screen, ENIG finish. From R&D to the production of PCB, component procurement, and then to the final post-SMT soldering and gluing, our company provides a full set of one-stop service for circuit boards, saving customers trouble, worry, effort and cost, winning the market, and achieving a win-win situation.
The following are the standard PCBA design and assembly services we can provide
Hope it makes sense, and below is the standard PCB assembly services we offer:
• One-Stop from Design to PCBA boards: we design the PCBA boards based on your needs and make the PCBA boards to meet all your needs.
• Turnkey PCB and Assembly: We make PCB boards following your Gerber files, purchase components as your BOM file, and do PCB assembly as the assembly drawing and P&P file shows.
• Multiple PCB Assembly Services: SMT, THT, Mixed Assembly, Package on Package (POP), Rigid PCBs, Flex PCBs - if there's a type of printed circuit board that can be assembled, we almost surely do it.
• Flexible Volume Assembly Alternatives: Prototypes, low volume, high volume — we do it all.
• Parts Sourcing: All components will get your approval before purchasing. We have years of experience and stable relationships with authorized electronic components manufacturers and distributors, so new & original parts will be provided.
• Comprehensive Quality Assurance: From visual inspection to AOI, X-ray inspection, ICT and FCT, we take quality control very seriously and test everything rigorously for functionality and quality.

Files Required for Turnkey PCB Assembly
| Files Required | Specification |
| Gerber files* | Gerber files in format of RS-274X for PCB fabrication, or other PCB files like .pcbdoc, .pcb, .brd, etc. |
| BOM files* | BOM file in excel format for components sourcing and PCB assembly. It should include the components basic information: Reference Designators, Quantity, Part number, Description, etc. Click BOM Template for your reference. |
| Pick & Place file* | Also known as Centroid file or XY data. It describes the position and orientation of all the surface mount parts and it can help us to quickly programming the SMT assembly machines. Click P&P Template for your reference. |
| Assembly drawing (if available) | It includes the positions and polarities of the components designators which can help us better understand your assembly needs, correcting some ambiguous or even mistaken placements, and ends up with an excellent job. Click Assembly Drawing Template for your reference. |
| Testing Guide & Test Fixtures (if necessary) | To ensure the boards quality, we can test the boards following the provided testing guide & test fixtures before shipping. |
| Programming files & Programming tool (if necessary) | We could do IC programing for our customers if required. |
