LOW VOLUME PCB ASSEMBLY
Low Volume PCB Assembly, also called Small Volume PCB Assembly, which refers to a small quantity of printed circuit board assemblies with quantity ranges from 25pcs to 5,000pcs, and this service always comes with DFM Checking and DFT Checking process. As a PCB assembly provider China, we provide full-turnkey PCB assembly service in low (/small) volumes, including PCB fabrication, components sourcing and PCB assembly. If in demand, we also provide value-added functional testing service to you.
Generally, in low volume board assembly project, Design for Manufacturing (DFM) must be carefully considered. As a quick-turn PCB assembly manufacturer, we will review your PCB files for any possible engineering concerns in your Gerber Files, BOM, assembly drawing(s) and/or your programming and special processing requirements. If in possible, the engineer will create the PCB panelization for your PCB(s) for PCB Cost down, and the panel is applicable for efficient assembly process. In the CAM processing stage, the CAM engineer will recommend a proper soler mask opening to ensure high yield rate while preventing solder bridging and other common PCB assembly faults. After bare PCBs arrival, our SMT engineer will check the physical board to confirm the pads aperture dimensions and SMT stencil thickness according to IPC-7525A standard. All work we do in any possible way are for reducing the cost and shipping on time.
Design for Testing (DFT) should be involved in your PCB design from the beginning even for prototype assembly and low volume board assembly. When you choose us as your PCB assembly supplier, you will be offered our professional suggestions on how to locate the test points on GTP and/or GBP layer, after reviewing your testing procedure. Testing procedures should contain (1) Troubleshooting Guidelines, (2) Diagnostic Tests, and (3) Documentations for supporting full testing can be conducted on your PCB assemblies. We can meet your testing requirements according to your testing procedures relied on our meticulous verification methods, such as AOI (Auto Optical Inspection), ICT (In-Circuit Test, FCT (Functional Test) and multiple stages of Visual Inspection.
How to Ensure Free of Risk in Quality for Low Volume PCB Assembly Projects?
- All bare printed circuit boards are 100% E-test
- Shipping you a few trial PCB assemblies for testing before the main production.
- Running main production with your approval after all testing are ok.
- Increasing visual inspection frequency on all main production.
- Conducting AOI inspection on all main production.
- Conducting X-ray inspection on sample size to check the assembly quality of BGA and other complex packages.
- if any assembly issues found, our experienced engineers can resolve them before shipping.
Our consideration of cost-down for low volume PCB assembly order is the same with yours. For repeat orders, the NRE and Stencil cost will be waived in one year from the shipping date of last batch. We reduce your per-part cost by shopping each part number with the major component suppliers and choosing quantities to get the lowest per-part price. Over the passed years of experience in providing PCB assembly service, we have built strong relationship with major suppliers in China, the USA and Hongkong to keep component sourcing cost competitive without compromising on our strict quality standards. We have confidence in providing you the best combination of turn-key PCB service, quality, price and delivery time in your low-volume PCB assembly order.
