Press-fit Solutions
The Importance of Press-fit Technology in Modern Industries
While Press-fit technology may be unfamiliar to some, it is a mature, lead-free interconnection method widely adopted across key industries such as aerospace, energy, and advanced manufacturing. Known for its mechanical stability, vibration resistance, and high current-carrying capacity, Press-fit offers significant advantages over traditional soldering methods.
This reliable connection technology plays a vital role in the performance and reliability of components such as IGBT modules, power terminals, backplane connectors, and high-speed I/O interfaces. It is especially critical in the growing demands of AI servers and industrial automation systems.
What is a Press-fit Connection and Why Does It Matter?
Press-fit connection is a PCB assembly method that does not require a thermal process. Unlike traditional SMT reflow soldering and through-hole DIP soldering, which involve heating all components during assembly, the Press-fit approach eliminates potential defects associated with soldering—such as cold joints, voids, or solder cracks.
It is especially advantageous in high-speed signal transmission, miniaturized via holes, ultra-multilayer PCB applications, and high-current pathways. Through the Press-fit method, a reliable mechanical connection is established between metal conductors and the PCB, fulfilling the physical requirements necessary for high-speed data transmission and high-current carrying performance.
