Comprehensive PCB Testing and Inspection
Printed circuit board testing and inspection is one of the most important processes in PCB manufacturing. The growing demand of PCBs in various electronic and industrial applications as well as the complexity of the designs have made PCB testing and PCB inspections two essential tasks. At APC, we offer a range of services related to PCB testing and inspection.
What We at APC Offer
As PCBs can range from simple to complex, we understand that every company will have different needs even when it comes to testing and inspection. For this reason, we offer 3 different types of inspection services. Clients can choose the service that will best suit their PCB design and allow the product to be delivered on time.
- AOI Inspection: Automated Optical Inspection (AOI) is one of the most popular and preferred testing methods used today. It uses an optical imaging system to detect faults, defects, and issues related to soldering and assembly. Customers choose this process for its speed and accuracy.
- Manual Inspection: Despite its limitations, manual PCB inspection is chosen by many customers. In this process, we have individual testers who thoroughly examine the PCB, its components, and the assembly. They check the efficacy of the soldering, the placement and rigidity of the components, and the functionality of the product. This is also an extremely cost-effective method.
- AXI Inspection: Automated X-Ray Inspection (AXI) is the upgraded version of AOI. It follows the same principle of optical imaging; with only x-rays being the mode of image capture. AXI allows for the inspection of non-visible solder joints. This method is particularly useful for complex Ball Grid Array (BGA) designs.
At APC, we suggest the best option to customers depending on the size of the order and the complexity of the PCBs. We also provide custom-made testing and inspection processes to ensure the efficacy of your PCB.
FAQs
What is PCB testing and inspection in manufacturing?
PCB testing and inspection involve verifying the quality, functionality, and compliance of printed circuit boards during and after manufacturing. This includes checking for electrical continuity, shorts, solder defects, and adherence to IPC and ISO standards.
Why is electrical testing important in PCB manufacturing?
Electrical testing ensures that every trace, via, and component connection on a PCB functions as intended. It helps detect opens, shorts, and misrouted circuits before the board reaches final assembly, reducing product failures and costly rework.
What standards are followed in PCB inspection at APC?
American Progressive Circuits, Inc. follows IPC-A-600, IPC-A-610, and ISO 9001:2015 standards to ensure PCB quality. These standards define the criteria for workmanship, defect tolerances, and inspection methods for printed circuit boards.
How are PCBs inspected for quality control?
At APC, PCBs are inspected using AOI (Automated Optical Inspection), visual inspections, and in-circuit or flying probe testing. These methods detect issues such as missing components, incorrect placements, poor solder joints, and electrical defects.
Can testing be customized for high-reliability PCBs?
Yes, custom testing protocols are available for high-reliability applications like aerospace, medical, and automotive. APC offers flexible inspection options based on IPC Class 2 or Class 3 standards to meet your project’s exact performance requirements.
