Lightning Strikes: ESD and Stencil Wiping

摘要

Conventional stencil wiping rolls contain a high percentage of polyester, leaving PCBs exposed to ESD damage.

Just as polyester clothes cling and spark when rubbed, fabric cleaning rolls retain static electricity generated in the manufacturing process.
