QLC with Solderless Plug - Miniature Zero Insertion Force

The QLC solderless plug is a groundbreaking 260 pin Zero Insertion Force connector that eliminates the need for hand soldering fine pitch contacts onto printed circuit boards, significantly reducing time and cost in the assembly process.

It eliminates the need for soldering by deploying a two card edge design with a slider that enables simple insertion and results in a high contact force connection to the PCB.

Derived from the existing marketing leading QLC product range, the new QLC solderless plug is fully intermateable with existing receptacles.
