Description

Bergquist Sil-Pad 1500ST (Soft Tack) is a fiberglass reinforced thermal interface material that is naturally tacky on both sides. Sil-Pad 1500ST exhibits superior thermal performance when compared to the competitors' thermal interface materials. Sil-Pad 1500ST is supplied in sheet form or roll form for exceptional auto-dispensing and auto-placement in high volume assemblies. Sil-Pad 1500ST is intended for placement between an electronic power device and its heat sink.

Typical Applications include

  • Power supplies
  • Automotive electronics
  • Motor control
