1. Product Introduction
SMT and Thru-hole hybrid PCB assembly is a comprehensive electronic manufacturing solution that integrates surface mount technology and traditional through-hole soldering processes. Surface mount components are adopted for high-density circuit layout and miniaturized product design, while thru-hole components ensure excellent mechanical stability, vibration resistance and high-current bearing capacity. This hybrid assembly method perfectly solves the structural and performance limitations of single-process PCBA, meeting the complex design requirements of high precision, high reliability and high power simultaneously. All products are manufactured in strict accordance with IPC-A-610 international industry standards, supporting RoHS-compliant lead-free soldering and traditional tin-lead soldering processes. We provide full one-stop services including DFM design review, component procurement, SMT placement, wave soldering, selective soldering, appearance inspection, functional testing and customized post-processing to ensure stable and consistent product quality.
