PROJECT-SPECIFIC REVIEW
PCB fabrication feasibility follows the approved stackup and drawing
Fabrication review connects material system, layer count, copper distribution, finished thickness, holes and vias, controlled impedance, surface finish, panelization, tolerances, inspection, and quantity.
Inputs required for review
- Gerber or ODB++ data, drill files, and fabrication drawing
- Approved material system and stackup constraints
- Copper weights, impedance targets, coupon and test requirements
- Finished dimensions, tolerances, markings, packaging, and acceptance standard
Fabrication workflow and controlled outputs
| Stage | Project-specific control | Recorded output |
|---|---|---|
| CAM and engineering review | Check layer order, board outline, drill groups, stackup, impedance, tolerances, panelization, and drawing conflicts | Reviewed data set and engineering questions |
| Inner layers and lamination | Use the approved material system, copper construction, registration plan, and lamination route | Lot and stackup records required by the order |
| Drilling and hole metallization | Separate through, blind, buried, filled, press-fit, and non-plated hole requirements; control finished dimensions and plating criteria | Hole-group and inspection records |
| Outer layers and solder mask | Transfer the released image and apply the agreed conductor, annular-ring, mask-clearance, and marking requirements | In-process inspection status |
| Surface finish and profiling | Apply the specified finish only to the defined regions; confirm edge plating, castellations, bevels, routing, scoring, and cleanliness as applicable | Finish and dimensional acceptance records |
| Electrical test and final release | Use the agreed net data, coupon, sampling, visual, dimensional, microsection, and packaging requirements | Lot identity and release documents included in scope |
The sequence is conditional: construction, hole structures, materials, finish, and inspection requirements determine the actual route. This page does not establish capability or acceptance before file review.
Conditions and limitations
Generic values for layer count, trace and space, drill size, HDI construction, copper weight, panel size, capacity, or lead time are not order guarantees. Combination limits are checked against the same controlled revision before quotation.
Evidence and next step
The controlled quotation should identify the reviewed revision, included operations, exclusions, acceptance evidence, responsibilities, and release conditions.
