Development and Release of the "PB-4H Series"the Industry's Smallest Class Space-Saving 0.4mm Pitch Board-to-Board Connector

We are pleased to announce that we have developed and released the "PB-4H Series" 0.4mm pitch board-to-board connector for smartphones and mobile phones.
While this product boasts the industry's smallest class space-saving design, it secures a sufficient adsorption area and has a unique structure to support automated implementation.
Further, by using a common socket part and providing products with varying heights, the board pattern will be the same even if the mating height is different, contributing to greater design flexibility.
Our unique contact not only improves the feeling of insertion but also realizes low mating strength even with multiple poles, contributing to improved usability when assembling.
