請問化學的前輩, 請問有溶劑可以清洗Mold Compound所形成的污漬嗎?

這玩意還挺冷門的, 不過您可以試看看這兩家的產品. P.S. 我不是業代 .

Outline
Transfer molding is the most common method of using the resin to encapsulate semiconductors. With continuous molding, however, the resin stain remains on the mold die, due to the oxidation of the resin constituents on the mold die, which could cause less releasability of the resin or inferior appearance of the device. Nitto Denko Cleaning Sheet (NCS) made of non-vulcanized rubber bonds with the resin stains when it is pressurized and recover the releasability of the mold dies.
這是一種非硬化性橡膠 (沒加硬化劑), 加壓之後可以把模內受高熱氧化的模渣黏下來 .
本來建議熱模噴砂 , 不過似乎太傷模具 . 用黏的應該比較好 . 不然只能拆下來放超音波洗槽, 把硬化的樹脂震下來 . Mold release compound (剝模劑) 該用好一點的, 當然也不能太省 .
