PCBA Electronic Assembly PCB Design Services PCB manufacturers

• Acquire all information needed, reviewing and verifying the accuracy.

• Schematic capture and net list generation (if not done yet).

• Create part library for the project.

• PCB component placement.

• Submit intermediate placement to engineer for reviewing. This is usually a discussion-

modification process until get approval on final placement.

• PCB routing. PCB designer and engineer must maintain adequate and frequent

communication during the routing process.

• Complete PCB layout, finalize all documents.

• Bill Of Materials (BOM).

• Final Net list.

• Hardcopy (or electronic version) of Schematics.

• Data sheets for special parts, if any.

• Any special instructions on layer stack-up (i.e. Signal, Ground & Power Planes) and plane splitting.

• Any drawing/detailed scratch showing board shape, size, and mounting mechanism, or heat sink, etc.

• Silkscreen text identification, including Part Numbers and Revisions.

• Any signals requiring special routing.

• Any placement requirements or restrictions (Placement ideas is greatly helpful).

• PCB Design Files.

• Standard PCB fabrication files (Gerber & NC-Drill in standard formats).

• Schematics and BOM if the schematic capture process involved in the design order.

• Assembly drawings.

• Assembly machine pick-place data file.

• Solder paste stencil files.

• Other optional files as client required.

• Provide as accurate information of circuit design and system requirement as possible.

• Avoid/minimize change on schematic after PCB layout process begins.

• Reducing density and making practical requirement.

• Choose responsible and highly skilled PCB designers.
