More and more Land Grid Array (LGA) components are being used in electronic devices such as smartphones, tablets and computers. In order to enhance LGA mechanical strength and reliability, capillary flow underfill is used to improve reliability. However, due to the small gap, it is difficult for capillary underfill to flow into the LGA at SMT level. Due to cost considerations, there are usually no pre-heating underfill or cleaning flux residue processes at the SMT assembly line. YINCAE solder joint encapsulant SMT256 has been successfully used with solder paste for LGA assembly. Solder joint encapsulant is used in in-line LGA soldering process with enhanced reliability. It eliminates the underfilling process and provides excellent reworkability. The shear st rength of solder joint is stronger than that of underfilled components. The thermal cycling performance using solder joint encapsulant is much better than that using underfill. Bottom IC of POP has been studied for further understanding of LGA assembly process parameters. All details such as assembly process, drop test and thermal cycling test will be discussed in this paper.

EAST HANOVER, NJ – Zymet has introduced a new reworkable underfill encapsulant, CN-1728, designed to underfill Package-on-Package (POP) assemblies. Underfilled POP’s have greater difficulty in passing thermal cycle tests than underfilled BGA’s. Compared to earlier generation underfills, CN-1728 has a lower coefficient of thermal expansion and higher Tg, and better compatibility with flux residues, both of which contribute to its superior thermal cycle performance.
