PCR®, abbreviated as Pressure-sensitive Conductive Rubber, is a rubber sheet in which metal micro-particles are aligned the direction of thickness by using our original method.
When pressed, the metal micro-particles contact each other and multiple conductive paths are made, which enables stable electric inspection.

■Advantages of PCR®

• ●Low inductance and good high frequency characteristics
• ●Directly mountable onto expanded board, and does not require complicated housing
• ●Positioning to expanded board can be done with Guide Pin method, one-touch exchange is available.
• ●Displacement tolerance is wider than point contact thanks to area contact
• ●Suitable for fine pitch with large pin numbers
• ●Good contact characteristics even for lead-free solder ball
• ●Virtually no ball/pad damage
