What is high Tg PCB (printed circuit board)

Normally high Tg refers to high heat resistance in PCB raw material, the standard Tg for copper clad laminate is between 130 – 140℃, High Tg is generally greater than 170℃, and middle Tg is generally greater than 150℃. Basically the printed circuit board with Tg≥170℃, we call high Tg PCB.

Hard Gold

▪　Usual thickness: 0.7 µm (0.00003”) to 1.3 µm (0.00005”) gold (99.7%) over 5.0

▪　µm (0.0002”) nickel or 0.2 µm (0.000008”) to 0.3 µm (0.00001”) gold (99.7%) over

▪　5.0 µm (0.0002”) nickel for a solderable surface

▪　Very good for corrosion resistance

▪　Rated at 130-220 Knoop hardness

▪　Very good wear resistance

▪　Excellent for surface rotary switches, on-off contacts, and edge connectors

▪　Very good shelf life
