Press-fit hole PCB: engineering review
Match the plated finished hole to the actual connector pin and application specification. This illustrative multilayer reference does not establish an existing KFPCBA production record.
All numeric and material callouts below are illustrative, unverified review inputs. They are not evidence of KFPCBA delivery, measured performance, certification or current manufacturing limits. A new order requires approved drawings and confirmation of the complete process combination.
Illustrative configuration inputs
| Review item | Illustrative input and unresolved conditions |
|---|---|
| Illustrative layer count | 16 layers |
| Candidate laminate | TU-872; exact grade and supply documentation unverified |
| Reference features | Press-fit holes, BGA regions and controlled-impedance nets |
| Unverified finish label | Gold; define the actual finish construction by region |
Review the engineering boundaries
A press-fit connection depends on the pin insertion section, finished plated hole and assembly tooling together. It is not a wire-harness crimp. An ordinary drill diameter or a passing net test cannot establish insertion force, retention or reliable connector fit.
Required RFQ inputs
Provide connector part number and current application specification, pin drawings, finished-hole dimensions and tolerances, hole-wall copper, board thickness, hole-array datums, pressing support, stackup and impedance groups.
Acceptance and traceability
Agree on finished-hole measurements, representative insertion and retention checks, electrical measurements and inspection of the connector/board/tooling combination. Record support conditions and sample identity; thresholds must come from the approved connector and project specifications.
Engineering review scenario
Changing connector series while keeping the same housing outline may change the required mating hole. Review pins, holes, plating and tooling before carrying the old hole table into a new revision.
This scenario explains a review method; it is not a documented defect or test result from a KFPCBA project.
Quotation and delivery scope
Itemize materials, fabrication, engineering preparation, agreed inspections, reports, packaging, taxes and freight. Identify quantity units, drawing revision, approved deviations and tooling ownership. Assembly, software and complete-system validation are separate unless expressly included. No published unit price, schedule or capability guarantee is established by this reference.
Finished holes and hole-wall copper · Inspection coverage boundaries
Submit fabrication files for review or use the short project inquiry. Identify this reference page and list the inputs still to be defined.
