Service
Through-Hole Assembly
Through-hole assembly supports SMT assembly when components require it: large connectors, high-current pins, mechanical mounts, and parts not available in SMT packages. We handle through-hole as part of the same job alongside SMT assembly.
What this service includes
- Selective through-hole assembly per assembly drawing
- Hand soldering or wave soldering as appropriate
- IPC-A-610 acceptance criteria applied to through-hole joints
- Combined SMT plus through-hole jobs on the same board
Production workflow for this service
- INPUT FILES
-
Assembly drawing review
Through-hole component list and orientation confirmed.
-
Component prep
Lead forming and trimming where required.
-
Insertion and soldering
Hand or wave solder per scope.
-
Inspection
IPC-A-610 visual inspection of through-hole joints.
- OUTPUT
When buyers need this
- Your design has connectors, headers, or relays that are through-hole only.
- You need a single partner for SMT plus through-hole on the same board.
Frequently asked questions
Which design files do you accept?
Gerber RS-274X, ODB++, and IPC-2581 for PCB data. BOM in xlsx or csv with manufacturer part numbers. CPL or pick-and-place file in csv or txt. Step files for enclosures. Firmware binaries as hex, bin, or signed image bundles.
How is solder joint quality verified?
Automated optical inspection runs on every assembled board against IPC-A-610 acceptance criteria. We support Class 2 and Class 3 inspection profiles. X-ray inspection is available through partner labs for BGA and high-density boards when required.
