Connectors & Terminals
For interfaces exposed to repeated mating, handling or cable load.
Through-Hole PCB Assembly
A through-hole route should protect the board, preserve solder access and create the right inspection evidence for connectors, terminals, transformers and mechanically loaded parts.

When The Route Fits
The correct route is confirmed from the released design. Hole size, lead diameter, thermal mass, clearance and nearby SMT all affect the process plan.
For interfaces exposed to repeated mating, handling or cable load.
For transformers, relays and parts with higher mass or thermal demand.
For capacitors, switches and mechanical components requiring defined insertion.
For programmes that combine dense SMT with leaded or high-load devices.
Controlled Production Route
Soldering and verification are planned together, so the inspection route is built around the component mix—not added only at final release.
Review Gerber or ODB++, BOM, drawings, insertion notes and test scope.
Choose manual, selective, wave or a coordinated combination route.
Control orientation, lead conditions, board access and thermal exposure.
Confirm workmanship, solder fill, testing requirements and release records.

Technology Selection
The technology should follow the product function and the complete production sequence.
| Requirement | Route To Evaluate |
|---|---|
| Fine-pitch parts and dense circuitry | SMT assembly |
| Connectors, terminals and high-mass parts | Through-hole assembly |
| Both technology types on one board | Mixed PCB assembly |
