With the rapid devolioment and maturity of intergrated circuit technology in recent years, metal-ceramic packages are seeing increasing popularity.
Main advantage:
✔ Can be welded directly with copper leads which carry high current
✔ Lead’s nase can be brazed with silver-copper, increasing tensile strength
✔ Can replace glass insulators to solve the off-centering issue sometimes encountered with glass sintering
✔ Achieve high-medium pressure resistance through structural options
