Copper-clad laminate and a bare industrial insulation laminate are not two different materials—they begin from the same epoxy-glass or polyimide base. The copper foil is simply bonded on top. Remove it and an FR-4 CCL becomes the same grade sold unclad for busbars, transformers, and switchgear. They diverge only in which specifications govern them. Read More

SiC modules switch at 20–100 kV/µs, and that speed—not just heat—ignites partial discharge. Learn how high dv/dt drives PD and how to qualify insulation to IEC 60270 (PDIV/PDEV). Read More

Every motor nameplate and transformer datasheet carries a thermal class. The table is copied onto a hundred websites. What the number actually promises is harder, and more useful. Read More

The two sheets above and below every drilled panel are the only materials in the process chosen to be drilled on purpose. What they do, and how to pick them. Read More

The part every drawing calls a "pull rod" is really a hollow tube. Why it is hollow, and how the wall, the bore, and the end fittings actually get designed. Read More

That compound goes by two names. In older European drawings it is DMC, dough molding compound. In American datasheets and most modern specifications it is BMC, bulk molding compound. Read More
