Through Hole Small PCBA Fast Turnaround One Stop PCBA ISO 9001 Certified

HTF delivers integrated surface mount and DIP mixed-technology assembly PCBA services for medical equipment and automotive electronics where modern circuit designs combine high-density SMT digital processing sections with through-hole power, connector, and interface components on single board assemblies. Our mixed assembly process begins with SMT component placement through solder paste printing, automated placement, and reflow soldering, followed by through-hole insertion and selective soldering that applies solder precisely to individual joints without exposing SMT components to thermal stress. Rigid-flex substrate capability supports applications where assemblies must conform to three-dimensional packaging constraints, with rigid sections for component mounting and flexible sections for interconnects or dynamic flexing. Our assembly line handles high-density designs with fine-pitch SMT components alongside through-hole connectors and power devices, backed by comprehensive testing including AOI for SMT solder joints, X-ray for hidden BGA connections, ICT for complete board verification, functional testing, and burn-in for reliability validation. Complete DFM review and BOM optimization services are provided with every project. Manufacturing capability spans from prototype through mass production with consistent quality. Circuit protection is a core focus area with specialized experience in fuses, PTC resettable fuses, TVS diodes, and protection ICs common in medical and automotive safety-critical applications.

HTF mixed assembly serves medical patient monitoring systems combining high-speed DSP SMT sections with through-hole isolated power supply and medical-grade connectors. Automotive ADAS camera and radar modules featuring BGA processor SMT sections alongside through-hole automotive connectors require carefully sequenced mixed assembly. Medical infusion pump controllers integrating microcontroller SMT processing with through-hole motor driver MOSFETs and medical-grade power connectors benefit from rigid-flex construction for compact portable device form factors. Automotive body control modules combining CAN bus microcontroller SMT sections with through-hole relay drivers and fuse holders represent the classic mixed-technology automotive application where HTF selective soldering delivers consistent quality.
