PCB Layout Process

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

· Schematic capture and netlist 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.

· During development of your product, our Printed Circuit Board designers will work closely with our electrical engineers and your mechanical engineers to ensure that the placement of parts meets both circuit and mechanical architecture needs.

· Complete PCB layout, finalize all documents.

Information Needed for A Design Order

· Bill Of Materials (BOM)

· Schematic in *.SCH files or PDF or Hand drawn format

· Final Netlist

· Data sheets for special parts, if any.

· Please specify if there is any critical Component placement or PCB dimension. 

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

· Any special instruction (like impedance control, current and voltage ratings, Speed etc..).

· 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


Documents Delivered with A Design Order

· 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.
