What to include in a RO4350B PCB RFQ

A useful quotation request includes fabrication data, board dimensions, quantity, layer count, exact material construction, finish, impedance requirements and test scope. The supplier needs enough detail to distinguish a simple RF board from a complex hybrid.

ENGINEERING ANSWER

A useful quotation request includes fabrication data, board dimensions, quantity, layer count, exact material construction, finish, impedance requirements and test scope. The supplier needs enough detail to distinguish a simple RF board from a complex hybrid.

What to decide before release

Send a revision-controlled fabrication drawing with the Gerber or ODB++ package and drill files. Identify which requirements are fixed and which may be proposed by the supplier. Ask for any assumptions and exclusions to appear in the quotation.

Checks to put in your design brief

  • Include stackup and finished thickness
  • State quantities and delivery needs
  • List required certificates and tests

Important distinction

A budget from board area alone is not a binding fabrication price. Use the estimate tool to explore assumptions, then request a formal quote.

Turn this into a design decision

Record your selected construction, the assumptions that affect this topic, and the evidence needed before release. Use the engineering workbench to prepare a preliminary calculation, then discuss the exact stackup and acceptance requirements with the fabricator.

Drilling RO4350B: process decisions

Drilling parameters depend on tool diameter, stack height, entry and backing materials, machine condition and the exact laminate system
