IPC-Certified Soldering Services for Wire Harness and Cable Assembly
As an IPC J-STD-001 certified soldering provider, OurPCB delivers professional hand soldering, splice soldering, and crimp+solder hybrid joints for wire harness and cable assembly applications. Our technicians are trained to IPC workmanship expectations for Class 1, 2, and 3 workmanship levels.
Hand soldering expertise covers connector contacts, coaxial RF connectors, terminal cups, solder lugs, in-line wire splices, shield drains, and heavy gauge wire termination. Controlled soldering technique helps prevent wicking, cold joints, insulation damage, and loss of strain relief.
Both lead-free (SAC305, RoHS compliant) and leaded (Sn63/Pb37) soldering options are available depending on application requirements. Aerospace and defense applications often specify leaded solder for reliability. Consumer electronics typically require RoHS-compliant lead-free processes.
Inspection methods include visual inspection with magnification per IPC standards, pull checks where applicable, insulation clearance review, and verification of wetting and conductor condition. Heat-shrink, sleeves, boots, and other insulation recovery methods protect completed joints from handling and environmental exposure. Our testing services verify electrical performance after soldering.
Proper soldering complements our crimping and ultrasonic welding capabilities for complete wire termination options, including approved crimp+solder hybrids and welded terminal connections. IPC/WHMA-A-620 workmanship standards govern our harness processes. Contact us for soldering quotes for your wire harness and cable assembly requirements.

Soldering FAQ
We follow IPC J-STD-001 for soldering processes and IPC-A-610 for acceptance criteria. Our technicians are trained and certified to these standards. We can work to Class 1, 2, or 3 requirements.
Yes, we offer lead-free soldering using SAC305 and other RoHS-compliant alloys. We also maintain leaded soldering capability for applications where lead-free is not required or practical.
Yes, we have extensive experience soldering RF and coaxial connectors. Proper techniques ensure good center conductor joints without damaging the dielectric or affecting RF performance.
We use visual inspection with magnification per IPC standards, pull checks where applicable, and electrical testing after soldering. Splices and terminations are checked for wetting, insulation clearance, strain relief, and conductor damage.
