Define the fabrication package
Keep the board revision, Gerber layers, outline, drill files and fabrication drawing consistent. Separate a bare-board order from assembly; an assembly quote also needs a BOM and placement data.
Specify the stackup
Ask the factory to propose the layer stack, dielectric thicknesses, finished copper and tolerances. List impedance targets with their reference layers and test method. The agreed stackup is the production reference; the 3D workspace is for illustration.
Specify the material
Record the exact grade and permitted alternatives. Compare electrical values at matching frequencies and test methods. Keep thermal requirements, surface finish and assembly conditions in the factory discussion.
List deviations
Ask each supplier to list deviations, the manufacturing site, minimum order, production lead time and the complete quoted cost. Agree each deviation before the specification is fixed.
Define acceptance evidence
Agree the required test reports, inspection records, samples, lot identification and acceptance criteria before signing. Decide who reviews each milestone and what happens if the delivered lot differs from the agreed specification.
Control revisions
Keep the original drawing fingerprint and agreed requirements with the contract. Revise the agreement before approving a substitution or a new file revision. The package label identifies the reference documents; the agreed tests confirm the physical board.
Material references: Isola 370HR · Rogers RO4350B. Use the current manufacturer documentation with the specific construction and test conditions.
