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.
THAILAND PCB · KNOWLEDGE & FACTORIES
Know the board. Know the factory.
A practical manufacturing guide, backed by a dated view of Thailand’s PCB industry. Turn research into better questions, clearer specifications and better documented orders.
What a factory needs to quote well.
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 3D workspace is a schematic aid; the agreed stackup is the production reference.
Choose material with context
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.
Make exceptions visible
Ask each supplier to list deviations, the manufacturing site, minimum order, production lead time and the complete quoted cost. Resolve the exceptions in the meeting room before the specification lines are locked.
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.
Keep changes traceable
Keep the original drawing fingerprint and agreed requirements with the contract. Revise the agreement before approving a substitution or new file revision. A matching package label identifies the reference; it does not certify the physical board.
