摘要

通过改变固化促进剂和改变环氧成型化合物(EMC)的体积电阻率,可以改善EMC应用封装的静电特性,降低IC器件的静电损伤。使用磷盐促进剂的电磁兼容产生的静电放电故障比使用磷盐促进剂的电磁兼容产生的静电放电故障低得多。由于磷盐在施加EMC时的体积电阻率比磷化氢盐的体积电阻率低,因此易于耗散传递成型过程中或成型后在封装内部产生的静电。

Electrostatic discharge failure control of IC package by epoxy molding compound modification
By changing curing accelerator and modifying the volume resistivity of epoxy molding compound (EMC), electrostatic characteristics of EMC applied package can be improved and electrostatic damage of IC device was reduced. EMC with phosphonium salt accelerator results in much lower ESD failure than EMC with phosphine salt accelerator. Because the volume resistivity of phosphonium salt applied EMC is lower than that of phosphine salt, it could easily dissipate the static electricity that generated inside of package during or after transfer molding process.
