PCBA Inspection

Quality management Policy:

Adoption of 5S, Lean Manufacturing. Products inspection is strictly conducted in compliance with internationally recognized workmanship standards (IPC-600E class Ⅱ standard).

For PCB assembly Quality:

HYHC is equipped with 3 x AOI equipments, 1 X-Ray machine for inspection on PCBAs, Flying Probe and ICT equipment for functional testing. In order to ensure a high

level of outgoing quality, we encourage our cus tomers to allow us to functionally test products at our premises for the further insurance of defect-free products and minimizing

RMAs. This also alleviates our cus tomers from secondary processing and allowing us to be of further service.

· Visual inspection: It mainly check the board thickness, surface roughness, and dimensions are accurate. You can use a ruler, precise calipers, or a magnifying glass for the

inspection. It also includes checking the quality of the plating flux, positioning of components, and the electrical connectors.

· AOI inspection: We do a 3D automated optical inspection of PCBs at an early stage of the production run. After the soldering stage, we deploy the technique. The value of

this is that we can detect flaws early enough and correct them.

· X-Ray inspection: The magnification and resolution are important parameters for identifying the inspection capacities of a machine. AXI offers very high image resolution

and magnification. Hence, it is able to accurately inspect even the smallest of products, we use this when the PCB is very thin.

· Electrostatic Discharge (ESD): Many components are sensitive to electrostatic discharge and an ESD test ensures that production follows all safe handling procedures.

Elements that are part of highly sensitive electronics like cameras, digital scales, and measuring devices need to pass an ESD check to identify defects.

· General electrical inspection: This involves two types of tests. A connecting performance test ensures that the connectivity of conductive patterns is in line with expectations.

An insulating performance test also checks the insulating resistors on the PCB planes are functioning correctly and pass all quality assurance checks.
