Frequently Asked Questions

How is FR4 manufactured?

FR4 is manufactured by impregnating woven fiberglass cloth with an epoxy resin system, then curing it under heat and pressure into rigid laminate sheets. Copper foil is bonded to one or both sides. Multiple layers are stacked and laminated together for multilayer boards. The resulting material achieves the Flame Resistant 4 (FR4) rating, confirming it will self-extinguish when exposed to flame.

What layer counts are available for industrial FR4 PCBs?

What is a High-Tg PCB and when is it needed for industrial control?
