What does a PCB engineer do?

PCB hardware engineers mainly do a good job in circuit design, PCB design, circuit testing and debugging scheme, BOM formation and confirmation in product PCB, components and devices purchased according to BOM testing, parameter adjustment and screening scheme, PCB job tracking and process testing, data collection of signal input test points during testing, parameter verification and QC confirmation of PCB passing, maintenance or scrapping after testing. Continuously improving the performance of circuit and PCB plays an important role in improving product quality, production speed, rationality of PCB structure and reliability of products.
