PCB RFQ Checklist: Files and Specifications Needed for an Accurate Quote
PCB quote requirements include complete Gerber files, drill data with PTH/NPTH designation, board specifications, and surface finish selection—the missing specification invalidates the entire quote request. Key Takeaways Complete Gerber file packages including all copper, mask, silkscreen, and board outline layers are mandatory for quoting Drill files must specify plated (PTH) versus non-plated (NPTH) holes clearly […]
Selecting a Multilayer PCB Manufacturer: Stack-Up, Registration and Reliability
Multilayer PCB manufacturer selection requires evaluating stack-up capabilities, registration tolerance, impedance compliance, and documented quality processes beyond basic fabrication competency. Key Takeaways Multilayer PCB manufacturers must provide stack-up documentation and verification, not just fabrication Layer-to-layer registration tolerance of ±0.05mm or better distinguishes advanced manufacturers Controlled impedance verification requires test coupons and TDR measurement methodology IPC […]
