New Gap Filler Pad Introduced
Posted: Friday May 24, 2013
Fujipoly announces the introduction of Sarcon® GR25A-00-50GY,
an extremely soft thermal gap filler pad that also exhibits a very low thermal
resistance.
FG-S Connectors

The FG-S Connectors have anisotropic conductionproperties. Thin metal wires are embedded with a vertical orientation within the silicone rubber on 0.10 mm centers. Low resistance and high current carrying capacity make this series very versatile for most typical interconnect applications.
The basic FG-S design is one row of gold-plated tips of Phosphor Bronze wires embedded in silicone rubber which will connect two parallel sets of contact, both having one row of contact pads.
