Technical Parameters of Protos Spacer (for Wafer use)
Spacer For Wafer Use is also called anti-static stacking pad, silicon wafer paper, semiconductor wafer box inner pad, solar wafer buffer pad, semiconductor wafer box inner pad, PCB buffer pad, conductive pad, black wafer pad, anti-static wafer pad, conductive wafer pad, round wafer pad, wafer block, and its surface treatment process is also called anti-static black embossed wafer pad, embossed wafer block, etc.
This product is made of permanent conductive or anti-static film by hot pressing and die cutting. The surface of the film can be made smooth or made into various patterns according to requirements. The product can be made into any size and shape according to requirements, and the finished product has good dimensional stability, neat appearance, no powder loss, and no dust. The raised pattern wafer gasket can not only effectively prevent the product from being damaged by static electricity, but also play a certain buffering role.

The primary benefits of using spacers is that it helps to control the gap between the wafers with an accuracy of a few micrometers. This tiny gap is essential for the proper functioning of the semiconductor device. Spacers also help to prevent contact between the wafers, which could lead to damage or contamination.
