sil-pad die-cut assortment
At NEDC, we cut a lot of custom parts. However, it is much more common to cut parts that are made to a specification or standard. In our M83528/004XDDD post, we talked about Standard Connector Gaskets. In this blog post, we talk about Standard Sil-Pad Configurations. These are all standard die-cut parts that NEDC has available for a number of Sil-Pad & Gap Pad materials. These are normally used in Power Supplies, Power Resistors, and other power devices. However, most of these standard Sil-Pad configurations are used on transitors. While Gap Pad is sometimes configured with these cut-outs, typically Sil-Pad is picked:

Examples of Sil-Pad Callouts
Of course, there are more varieties available in different Sil-Pads and Gap Pads. A typical callout in the legacy Bergquist system usually went something like:
SP2000-0.010-AC-12(Sil-Pad 2000 in .010’’ thickness, PSA one side, in the -12 condition, i.e TO-18 small power device)
SP980-0.009-00-25(Sil-Pad 980 in .009’’ thickness, no PSA, in the -25 condition, i.e DO-5 diode washer)
SP400-0.009-AC-54(Sil-Pad 400 in .009’’ thickness, PSA one side, in the -54 condition, i.e TO-220)
SPK10-0.006-AC-60(Sil-Pad K10 in .006’’ thickness, PSA one side in the -60 condition, i.e TO-126)
