Package Probe (Test Socket)

Customization for a test socket best suited to the testing environment

MJC provides two types of test sockets by customizing them to have specifications most suitable for your testing environment.
The BeeContacts series offers test sockets featuring a unique structure for self-cleaning, making them suitable for Pb-free packaging, and a long life, which contributes to less frequent cleaning and yield improvement.
The J-Contacts series offers highly reliable test sockets, suitable for measuring high frequency devices.
