POLYMER SEALANT/ADHESIVE AND ITS USE IN ASSEMBLING ELECTRONIC PACKAGE |
摘要 |
<p>PROBLEM TO BE SOLVED: To obtain a siloxane-containing polyimide adhesive capable of TSM capping with a reduced seal band width in assembling an electronic package and soluble in a solvent friendly to the environment by using an aromatic diether dianhydride, an aromatic diamine having a flexible molecular chain and a polysiloxanediamine. SOLUTION: The composition for forming the adhesive comprises an aromatic diether dianhydride, an aromatic diamine having a flexible molecular chain and a polysiloxanediamine having a vinyl functional group as part of the structure. The molar ratio of the anhydride to the total diamines is about 0.95/1 to 1.05/1, and an excess molar amount of the reactants are capped with a monohydride or a monoamine compound. This composition is polymerized to obtain a siloxane-containing polyimide adhesive. The seal band width is below 4mm.</p> |
