发明名称 Reflow encapsulant
摘要 A reflow encapsulant is used with substrate and an electronic device. The encapsulant is configured to cure when the assembly is heated so as to reflow solder bumps connecting the substrate and electronic device. The encapsulant includes inorganic filler in an amount of 8% to 20% by weight. The amount of filler provided is sufficiently high to lower the CTE of the encapsulant so as to enhance cured material properties and prevent undue expansion and solder joint damage, but low enough so that the solder joints are not affected by filler particles during reflow.
