A silicon rubber socket is a test socket contact method that connects electrically to the interface board for semiconductor package testing, in which conductive microballs are placed inside a rubber silicon rubber. In particular, it has a low signal loss due to the short thickness of the terminals that transmit signals, giving it an advantage in high frequency areas
• Strong at testing the QFN device
• High and stable test yield compared with Pogo socket
• Longer life time (1M~ insertions)
• Down time reduction due to cleaning problem
