ISO 9001 Certified Rigid Flex PCB Assembly Lead Free PCBA Assy RoHS Compliant

HTF provides specialized DIP through-hole assembly PCBA services for medical equipment and automotive electronics applications where dual in-line package and other through-hole components remain essential for electrical performance, mechanical robustness, power handling, or connector reliability. Our DIP assembly operation combines automated axial and radial component insertion equipment for high-volume through-hole placements with skilled manual assembly stations for complex multi-pin DIP packages, large connectors, power transformers, and heat-sinked semiconductors requiring precise mechanical alignment before soldering. Wave soldering with dual-wave technology processes boards with predominantly through-hole component populations ensuring complete hole fill, while selective soldering with programmable nozzle positioning handles mixed-technology boards where through-hole components are interspersed among SMT devices. For medical equipment where patient safety depends on connector reliability, DIP assembly provides superior mechanical anchoring of through-hole solder joints. For automotive electronics where modules experience extreme temperature cycling and continuous vibration, through-hole mounting of connectors and power devices provides mechanical robustness that surface mount alone cannot guarantee over a 15-year vehicle service life. DIP assembly is supported by complete HTF turnkey infrastructure including authorized component sourcing with full traceability, comprehensive testing from AOI through burn-in, and flexible production volumes from prototype through mass production.

• Dedicated DIP Assembly: Automated insertion for high-volume DIP packages plus skilled manual assembly for complex connectors and power components.
• Dual-Wave Soldering: Turbulent first wave for hole fill and smooth second wave for finish quality producing reliable solder joints on through-hole dominant boards.
• Selective Soldering: Programmable nozzle technology applying solder to individual joints without thermal stress on surrounding SMT components.
• Medical Equipment Reliability: Through-hole processes validated for medical device manufacturing where connector reliability impacts patient safety.
• Automotive Durability: Through-hole mounting providing superior mechanical anchoring for components in modules experiencing extreme thermal cycling and vibration.
• Authorized Sourcing: Component procurement with complete lot traceability supporting medical and automotive regulatory documentation.
• Comprehensive Testing: AOI, X-ray, ICT, functional test, and burn-in for complete reliability validation on every assembly.

HTF DIP assembly serves medical power supply modules for patient monitors, infusion pumps, ventilators, and diagnostic imaging systems depending on through-hole mounting for large filter capacitors, power transformers, and medical-grade connectors. Automotive ECU power stages, ABS solenoid driver modules, and electric power steering controllers require through-hole for high-current connectors, power MOSFETs, and electrolytic capacitors handling substantial currents and thermal cycling. Medical laboratory automation including sample handling robots, centrifuge motor controllers, and incubator control modules utilize DIP assembly for stepper motor drivers and relay output modules where through-hole reliability supports continuous operation.
