Frequently Asked Questions

Common questions about our through hole services.

We offer wave soldering for high-volume production, selective soldering for mixed-technology boards, and expert manual hand soldering by Japan-trained technicians for complex or heat-sensitive components.

Absolutely. Mixed-technology PCB assembly is one of our core strengths. We integrate our SMT and THT lines to handle boards requiring both surface mount and through-hole components in a single production flow.

All through-hole assemblies are inspected against IPC-A-610 workmanship standards. Our triple ISO certification and Japanese-trained workforce ensure consistently high-reliability solder joints.
