I-PEX® ISH® is a high heat/vibration resistant wire-to-board connector series. Horizontal, vertical, wire-to-wire and hybrid (with power terminals) types are available. Female terminals with the embedded spring provide superior contact reliability.
I-PEX® ISFIT® is a solderless press-fit terminal with a unique design that includes a 4-point contact with an internal spring structure that provides low mating force and eliminates damage to the through-hole on the PCB. This terminal has excellent contact reliability with accurate center position alignment which helps reduce the workload of assembly operators, as well as improving the inspection process.
Solderless press-fit type connectors are commonly used in the PCB based assembly process. Whereas conventional connectors are soldered directly on the board, press-fit connectors can be mounted using a simple press-fit method, which simplifies the process. This reduces manufacturing costs by eliminating the solder mounting process.
However, the press-fit method could cause damage to the PCB and requires great press force for mounting. In order to solve these problems, I-PEX offers a completely new concept terminal: the ISFIT®series.
Our unique terminal design with the spring structure eliminates the damage to the PCB during the insertion process.
The conventional eye of the needle type terminal without the spring structure causes damage to the PCB
through-hole edge, as well as the inside wall.

The ISFIT® spring structure terminals absorb the insertion force during the insertion process. It lessens the coefficient of friction compared to the eye of the needle version, keeping the insertion force lower from start to finish.
