Reliable thru-hole PCB assembly for high-current, high-vibration, and mission-critical designs.
Thru-hole assembly remains essential wherever connectors must hold fast, transformers carry real power, or products face heat, vibration, and years of use. OSDA delivers THT builds using selective soldering, wave soldering, and skilled manual techniques, supported by proper lead forming and component retention methods that protect joints through the product’s life.
We align process to design intent. Fixtures and pallets are tuned for each job, nitrogen profiles and dwell are dialed in, and first-article approvals are used to lock repeatability. With RoHS-compliant processes, ISO 9001 and ISO 13485 quality systems, and IPC-trained technicians, you get thru-hole assemblies that stand up in the lab and in the field.
Thru-hole shines where mechanics and power intersect. Think high-pin-count I/O connectors, transformers, inductors, relays, tall heat-generating devices, and chassis-mounted hardware. We plan insertion, clinching, and retention up front, manage thermal mass with correct preheat and fluxing, and use selective solder pallets to protect adjacent areas. For specialty parts, our team performs precise lead forming, staking, and potting to control stress and vibration in service.
Most boards aren’t all-or-nothing. We routinely build mixed SMT + THT designs, sequencing reflow and selective/wave so one process never compromises the other. Keep-outs, masks, and fixture design are reviewed early. The result is less rework, cleaner joints, and predictable cycle times—even on dense, multi-technology assemblies.
Quality for thru-hole assembly isn’t guesswork. We verify hole fill, fillet shape, meniscus, polarity, and lead protrusion under magnification; apply AOI where appropriate; and validate builds with functional test, ICT where available, burn-in, and HiPot for power assemblies. Documented work instructions, first-article acceptance, and lot-level traceability keep every run consistent. All of it sits under ISO 9001/ISO 13485 and RoHS controls.
With DFM & Design Support, we help identify potential challenges early, minimizing costly rework and ensuring smooth transition from prototype to production. We support turnkey, consigned, or hybrid models, and we plan for the long haul. That includes last-time buys, obsolescence management, spares programs, and Kanban for steady demand. If an ECO lands mid-build, our team coordinates fast, minimizing scrap while keeping schedules intact.
Thru-hole assembly that balances mechanical integrity, electrical performance, and repeatability for real-world conditions.
Proven Processes for Power and Connector Components
Thru-hole technology remains indispensable for components that demand strength, stability, and long-term reliability. With selective, wave, and skilled manual soldering techniques, OSDA delivers assemblies that perform reliably in mission-critical environments and across the most demanding applications.
Thru-hole assembly remains essential in applications where mechanical strength, durability, and reliability are required. Unlike SMT, thru-hole components form stronger physical bonds with the PCB, making them ideal for connectors, transformers, high-power devices, and products exposed to harsh environments.
At OSDA, we integrate thru-hole capabilities into our broader manufacturing process, giving customers the advantage of both surface-mount and thru-hole expertise under one roof. This hybrid approach ensures designs are built with the right technology for the right application, resulting in products that perform in the field.
From prototypes to production, we deliver thru-hole assemblies that withstand demanding environments and maintain performance over time. OSDA’s thru-hole assembly supports industries where product reliability is mission-critical.
OSDA’s thru-hole assembly services ensure that every joint, every connection, and every component stands up to the demands of real-world use. By combining advanced soldering equipment, skilled technicians, and certified processes, we deliver thru-hole assemblies that customers can trust to perform where it matters most.
