Custom Rigid PCBs from Prototype to Production

Choose the layer count around routing density, component connections, power distribution, and signal requirements. Single-sided or double-sided boards may suit simpler layouts, while multilayer constructions provide additional routing and reference-plane options. Share your layout and proposed stackup for a manufacturability review; the most suitable construction depends on the complete design, rather than layer count alone.

State the required copper weight for each layer and the surface finish in your fabrication notes. Copper selection should account for current, temperature rise, routing space, and manufacturability. Surface finish should match the component types, soldering process, contact requirements, and storage conditions. Share these requirements with XinshunPCB so the combination can be reviewed before production.

Send Gerber or ODB++ files, drill data, the board outline, and fabrication notes. Include the layer count, finished thickness, material requirements, copper weight, surface finish, order quantity, and requested delivery date. Add impedance targets, special tolerances, and inspection requirements where applicable. XinshunPCB can review these details to clarify the build requirements before quotation.

Define the applicable acceptance criteria, electrical testing requirements, dimensional tolerances, and any impedance verification or inspection reports needed. Include requirements for lot identification and traceability where relevant. Agree on the inspection scope and documentation before production so the delivered boards can be checked against the approved fabrication files and purchase requirements.

Specify the laminate grade or the performance requirements your application needs. FR-4 is a common starting point, while temperature exposure, signal frequency, electrical loss, and assembly conditions may call for a different grade or a hybrid stackup. Include any required high-Tg or halogen-free properties, and identify whether equivalent materials are acceptable. Material selection should be reviewed together with the stackup and operating environment.
