TOPIC FOCUS
Treat insertion and soldering as one controlled route
The assembly drawing should identify polarity, seating, lead-form rules, solder access, keep-outs, fixtures, manual operations, inspection points, and test requirements.
PCB Assembly
Through-Hole Assembly
Through-hole assembly planning should define insertion orientation, lead preparation, soldering route, thermal exposure, heavy-part retention, masking, inspection, cleaning, and post-process testing.
APPLICATION BOUNDARY
Confirm against the released project
A through-hole designation does not select wave, selective, or manual soldering by itself. Component geometry, board layout, heat sensitivity, side clearance, and acceptance criteria determine the route.
PROJECT FLOW

Decisions to document before release
Use this topic-specific checklist with the linked engineering reference. Record the actual project conditions and the agreed acceptance scope.
| Decision | Input to confirm | Record to retain |
|---|---|---|
| Insertion | Orientation, lead form and seating height | Assembly drawing and fixture notes |
| Soldering | Wave, selective or manual access and heat limits | Chosen route and masking needs |
| Release | Joint inspection and functional checks | Acceptance record after soldering |
Use published configurations to frame the next engineering question
These records provide context for the topic. They do not replace review of the current files, materials, quantities, tests, or acceptance conditions.
Through-Hole Assembly
Relay control board through-hole assembly
Relay control board through-hole assembly pricing depends on relays, terminals, control interfaces, and load conditions. Compare insertion, soldering, fastening, programming, and actuation-test scope; distinguish board-level checks from external-load verification, and check material supply and lot records.

Through-Hole Assembly
Power interface board through-hole assembly
Power interface board through-hole assembly reference configurations cover power distribution, polarity protection, and branch fusing. Separate SMT, large-component through-hole soldering, cleaning, mechanical fastening, and testing; compare material supply, setup, and per-lot assembly costs. Check branch continuity, protection direction, voltage-drop, and thermal-distribution test scope, plus interface board + branch definitions + material lots + load-record deliverables.

Through-Hole Assembly
Equipment driver board through-hole assembly
Review through-hole assembly for an equipment driver board with coil or actuator outputs. Define power devices, insulation, heatsink installation, feedback, firmware, and loaded protection tests in the RFQ.

Multilayer PCB
Inverter control PCB fabrication
Six-layer inverter control boards: review power and sensing nets, terminal holes, isolation slots, and copper inspection. All values are illustrative; approve fabrication drawings and acceptance criteria before ordering. Assembly and system verification require separate scope.

Prototype PCB Assembly
Motor driver PCBA prototyping
Motor driver prototype assembly references cover three-phase drives and current/position-feedback checks. Compare materials, SMT, later-installed power parts, staged power-up and energy-limited testing. Define gate, phase-sequence, sampling, controlled-load and protection tests, and retain measurement records and component-change revisions.

PCB Assembly Knowledge
How do DIP through-hole assembly, wave soldering, and subsequent soldering differ?
Compare through-hole insertion, wave soldering, and later soldering operations using lead-to-hole fit, component thermal limits, process routing, and final inspection requirements.
