  • Correct PCB stackup and panelized

  • Provide correct SMT files

  • Completed programmable and testing method

  • Clearly assembly manual with finished product

  • Other special manufacture requirements

  • BOM and PCB pad inspection (some of customers changed the Gerber files and didn’t update BOM in time, that caused sourcing wrong components)

  • Evaluation PCB manufacturing, including but not limited to: sequence of assembly, stencil type, direction before oven and tool production, analysing heat-absorbing pads and surrounding components, moisture sensitive device/thermosensitive device protection, PCBA testing plan and detectable rate, quantity for trial production and report etc.
