Common questions buyers ask before sending files for quotation.

What files should I send for multilayer PCB quotation?

Please send Gerber files, drill file, stack-up, board size, copper thickness, surface finish, solder mask color, quantity and delivery requirements. If PCBA is needed, please also send BOM and assembly notes.

Can YC PCB review HDI or impedance control projects?

Yes. YC PCB can review HDI, blind via, buried via and impedance control requirements based on your Gerber file, stack-up and target performance.

Do you support prototype and mass production?

Yes. YC PCB supports prototype from 1 pc, small-batch production and mass production. Lead time and pricing depend on layer count, materials, process and quantity.

Which surface finish should I choose?

ENIG and immersion gold are often selected for fine-pitch SMT, BGA and high-reliability assembly. HASL and OSP may be suitable for standard or cost-sensitive projects. YC PCB engineers can recommend the finish after reviewing your application.

Can I request testing records or packing proof?

Electrical testing is part of PCB quality control. AOI, X-Ray inspection, packing photos or shipment records can be discussed based on project requirements.
