Package-on-Package (PoP) assembly is most commonly carried out by printing solder paste onto the substrate and placing the logic chip into the paste. The memory package is then either dipped into a specially-designed PoP flux or solder paste and placed on top of the logic chip. The whole assembly is then reflowed. No-clean processes are used.

Graping Defect是由一家著名手机公司定义的defect. 大致是这样：由于微型化 miniaturization, 元器件更小了，0201 甚至 01005， 所使用的焊锡膏的粉末球半径也更小了， 由以前的3号粉， 到现在的4号， 4.5号，甚至5号5.5号粉。 在相同体积的焊锡膏中，…
When designing a Package-on-Package (PoP) assembly process, there are many variables that need to be considered in order to be successful. While the chemistry of your PoP dipping flux or paste plays a major role in PoP assembly, there is also much to consider in terms of the components, equipment,…
