In the early days of PCB Assembly Manufacturing, all inspection was undertaken manually. This was the best option, but was recognized as having only limited value. The repetitive nature of the process meant that many faults were not spotted and passed on into the next stage of production undetected.
In modern PCB SMT assembly industry, there are many inspection and testing methods for verifying the build quality of a particular board. Visual Inspection is sophisticated software inspection method. As a Turnkey PCB Assembly Manufacturer and Supplier, we offer a wide range of inspection and testing methods as below,
- Visual Inspection
- SPI (Solder Paste Inspection)
- AOI (Automated Optical Inspection)
- X-ray Inspection
- FCT (Functional Circuit Testing)
- ICT (In-Circuit Testing)
These PCBA inspection methods such as these help us to guarantee quality for all types of modern PCB projects in full turnkey orders, but even with computerized tools at our disposal, standard visual inspection remains a vital part of our quality assurance strategy.
PCB Assembly Inspection can be conducted by our experienced quality engineers at various assembly manufacturing processes from paste screening thickness to parts placement, and though each soldering procedure. Performing incremental inspections allows for early detection of any errors, and ensures minimal impact to the overall PCB Assembly project lead time if any corrections are required.
Visual Inspection is the most cost-effective method for PCB assembly testing on straightforward Prototype PCB Assembly and Low Volume PCB Assembly Projects, allowing for the most competitive pricing without compromising on quality. At our PCB Assembly Factory China, we offer Visual Inspections as a standard service on all our PCB Assembly orders. Even when more complex methods are required, as illustrated in the table as below, we still provide Visual Inspection at no additional cost to our clients.
| Order Quantity | Components Qty per PCB | Visual Inspection | AOI |
| Q<=10 | N/A | Yes | No |
| 10<Qty<50 | Parts<50 | Yes | No |
| 10<Qty<50 | Parts>=50 | Yes | Yes |
| Q>=50 | N/A | Yes | Yes |
