Abstract
Gold Plated lid can be widely used for Hermetic package of integrated circuits.The marks on lid surface are usually made by offset printing with ink. But the ink mark, in the authentication process, exist partially exfoliated risk (Cause authentication through difficult). The green laser marking technology on gold-plated lid, has solved the problem well which marking falls off on gold-plated lid. At the same time also solves the process problem which printing serial number on gold-plated lid of the high reliability integrated circuits. The samples after laser marking,successfully passed the test of temperature cycle,heat concussion and the salt-fog test required by GJB548B standard. Laser marking area of gold-plated lid were analyzed by SEM and dissection. The results showed that the composition and thickness of the laser marking gold layer were unchanged.关键词
