White Core BT Board PCB is a resin chemical trade name produced. It is synthesized by bismaleimide (BMI) and cyanate ester (CE) resin. BT resin-based copper clad laminate (BT board for short) Because of its high glass transition temperature (Tg), excellent dielectric properties, low thermal expansion rate, good mechanical characteristics and other properties, it can make it popular in the current high-density interconnect (HDI) It is widely used in multilayer printed boards and packaging substrates.
BT boards were only used in chip packaging at first, and there are more than a dozen varieties, such as: high-performance copper clad laminates, chip carriers, high frequency copper clad laminates, resin-coated copper foils, etc., which are more widely used.
