Outgoing Quality Control - OQC

All of these are a significant part of our OQC processes for comprehensive confirmation and verification. During the OQC phase, our quality inspection process is based on simple and routine sampling inspections. We also perform full inspections for high-grade or high-priced materials. Our OQC processes include but are not limited to):

1. Functional testing: Confirming the full working performance of circuit boards and also checking for the performance of auxiliary parts.
2. Confirmation of packing list: This is used to ensure that what we have on the packing list is complete. We make sure that we exclude all foreign items from getting into fully packaged PCBs. We check for loose parts by shaking the box. Our QC staff (packaging department) usually confirms the presence of important components. They will check for the product manual, the warranty card, the text, and the language. After verifying the correctness of the product dimensions and label specifications we will also check for the accessories and the legibility of the text. We will verify the accuracy of the quantities and specifications. If the PCBs meet all of these requirements and specifications, they will be signed off as passed.
3. The appearance of the product: We will verify all parts of the PCB for completeness. This is confirmed with the use of an optical test. The test is also used to check for the correct direction of polarized components. It can also be used to check for the cleanliness and smoothness of the solder joints. Visual inspection is also used to check for defective joints like missing solder, shorted pads, burns, and inadequate solder.
4. Checking the packaging: We usually check the packaging of our PCBs because they represent the quality of our products. We check that the packaging has the right printing and label. We also ensure that the color of the package complies with our Pantone specifications. We also ensure that the packaging is undamaged and firm to support better product handling. We also perform functional check-ups connected to product packaging like sticker and barcode positions. Finally, we usually check and confirm that the outer and inner boxes have the right strength and size to ensure that the products are sound and safe as they are being transported.
