Through-Hole Assembly Services
What is the minimum order quantity (MOQ) for through-hole assembly?
We support highly flexible volumes, from single prototypes and engineering validation builds to high-volume mass production.
How fast can you deliver prototypes?
Depending on complexity, Rich Full Joy can provide quick-turn prototypes in as little as 3–5 days with full DFM (Design for Manufacturability) support.
Do you handle mixed-technology assemblies with both SMT and through-hole components?
Yes. We specialize in hybrid PCBA, sequencing SMT first and then wave/selective soldering, with optimized thermal profiles to ensure reliability.
Can you provide both leaded and RoHS-compliant through-hole soldering?
Absolutely. We support SnPb (tin-lead) and lead-free RoHS processes, ensuring compliance with customer and regulatory requirements.
What types of components can you assemble with through-hole technology?
We handle axial, radial, DIP, power semiconductors, transformers, relays, and connectors—both single- and double-sided soldering.
Do you support conformal coating or potting for environmental protection?
Yes. We provide conformal coating, underfill, and potting for assemblies requiring resistance to vibration, moisture, and dust.
How do you ensure soldering quality in through-hole assembly?
Every build undergoes IPC-A-610 Class II/III workmanship standards, AOI/X-ray inspection, ICT, and functional validation. Selective soldering is used for critical joints to ensure repeatability.
Are your processes certified for demanding industries like defense and medical?
Yes. We are certified to AS9100D (aerospace), ISO 13485 (medical), IATF 16949 (automotive), and ISO 9001/14001.
Do you offer complete turnkey services?
Yes. Rich Full Joy provides end-to-end PCBA services: PCB fabrication, component sourcing, through-hole and SMT assembly, testing, coating, and final box-build integration.
