C-EP 4619 Technical Data Sheet
Single component epoxy adhesive單組分環(huán)氧樹脂粘接劑
PRODUCT DESCRIPTION 產(chǎn)品介紹
C-EP 4619 is a One-component CSP/BGA corner bond fill material. It can be cured during lead-free solder reflow while allowing self-alignment of IC components. The material can be pre-applied to the board at the corners of the CSP pad site using a Standard SMA dispenser. When heat cured, it improves mechanical reliability of hand-held Devices. The material is reworkable. C-EP 4619是一種單組分CSP/BGA轉(zhuǎn)角粘接填充材料,它在無鉛回流焊接中固化的同時還能自動準(zhǔn)直IC元件。使用標(biāo)準(zhǔn)的SMA(表面安裝粘接劑,貼片膠)分散方式,該材料可以預(yù)先施加到電路板上的CSP襯墊處的轉(zhuǎn)角位置。加熱固化后,該材料可提高手持設(shè)備的機(jī)械可靠性。C-EP 4619具可返修性。
