MJC | MJC is well known as the leading supplier of high tech probe cards for wafer test. MJC also has a range of high tech contactors with exceptional electrical performance based on their J-Pin technology. The "J-contact" test contactor, is designed for a variety of applications including high-frequency devices such as Cellular phones, Bluetooth and high-speed memory, low noise devices such as Audio PreAMP and HDD R/W AMP, VCO, SAW Filter, RF IC, etc. In addition MJC have produced a new "no clean" pin for lead free applications which is showing more than 200k touchdowns without cleaning. In production more than 500k touchdowns have been realized before pin change is needed. The J-Pin, developed 10 years ago, was the first pin that rolls on the loadboard rather than scrubs, thereby reducing load board wear.

The "J-contact" meets the need for fine pitch package device with pitches to 0.3mm, is available for SMD packages such as QFN and DFN and leaded packages such as SOP, TSSOP, SOT and QFP. MJC's "Speedload" contactor strip significantly reduces maintenance times.
