Multilayer PCB
What layer counts do you support for standard production?
We commonly build 4–16 layer PCBs for automotive and industrial applications, and up to 30–40 layers for telecom, server and special projects. Higher layer counts can be evaluated based on design and reliability requirements.
Can you help optimize my existing stack-up for better cost or performance?
Yes. Our engineers can review your current stack-up, materials and impedance requirements, then propose alternatives that reduce cost, improve SI/PI, or enhance manufacturability.
How do you control impedance on multilayer PCBs?
We design the stack-up using known dielectric constants and thicknesses, run field-solver calculations, add impedance coupons on each panel and verify them via TDR to meet the specified tolerance.
What documents should I provide for a multilayer PCB quotation?
Please provide Gerber/ODB++ data, stack-up or layer count, board thickness, copper weight, surface finish, impedance requirements, target quantity and any relevant standards (e.g. IATF 16949, IPC Class 3).
Can you also assemble my multilayer PCBs into finished boards?
Yes. Rich Full Joy offers full PCBA services, including component sourcing, SMT/THT assembly, functional testing and even box-build, so you can move from bare board to complete electronics with one partner.
