Printed Circuit Board Testing Services and Solutions by Suntronic Inc.
- 2. INTRODUCTION Ensuring the reliability and optimal performance of electronic products is essential for electronics OEMs. In their pursuit of excellence, these manufacturers recognize the crucial role that printed circuit boards (PCBs) play in the performance of electronic devices. Defects in PCBs can cause device malfunctions or failures, which is why we, at Suntronic, Inc. provide a wide range of electronics testing services to address this issue. Page 02 of 1 1 Our comprehensive selection of testing services includes various types of functional testing and burn-in testing. By subjecting all PCBs and PCB assemblies to meticulous testing, we can identify and rectify any potential defects before shipping the products to our customers. This proactive approach ensures that our clients receive high-quality, reliable PCBs that meet their exacting standards.

These capabilities include:
- 4. BURN- IN TESTING Page 04 of 1 1 To assess the reliability and long-term performance of rigorous testing process involves subjecting electronic devices, we employ burn-in testing. This the products to elevated temperatures and stress conditions for an extended period. By doing so, we can identify any latent defects or weaknesses that may arise over time, ensuring that the product withstands demanding operational environments. By employing the burn-in process, we can mitigate the risk of premature failures and enhance the overall quality and reliability of our products.

A flying probe machine can access the ends of components or unintended vias as test points. The machine can be programmed to check the value of passive parts, their voltage measurements, and the transistor/diode orientation. This method is very accurate and can measure values at 99% accuracy. FLYING PROBE TESTING Page 05 of 1 1

The purpose is to verify on the board and connected to the the correct installation and connectivity of the components, as well as to check for any faults such as open circuits, short circuits,or incorrect component values. In-circuit testing is an effective method for quickly and accurately identifying manufacturing defects and ensuring the quality of PCBAs.
- 7. As the name suggests, this type of testing is performed using X-rays. We employ X-ray systems capable of 2D and 3D inspection workflow. The X-ray inspection is ideal for inspecting hidden joints in underside pads and ball grid arrays (BGAs). The X-ray inspection helps detect solder voids and has one of the highest detection rates of faults, which are not otherwise detectable by inspection. X- RAY I NSPECTI ON Page 07 of 1 1
- 8. AUTOMATEDOPTI CALI NSPECTI ON (AOI ) The automated optical inspection (AOI) uses 2D or 3D cameras to take images of the PCB. The image is compared with the images of PCB design being tested and the database of images of bad and good boards. The AOI machine can be integrated at the end of the production equipment. It helps detect major solder defects, and is suited for testing mature products in large batches. Page 08 of 1 1
- 9. Design for Testing or DFT is a technique which essentially prevents creation of designs which may be difficult to test well at any of the stages or may create compatibility issues at later stages. DFT considers various aspects such functional feasibility and testability as the of a product or circuit board while it is designed and developed. being reduce It helps and unnecessary associated costs, time, design-related complexities.
