 日本SUNSTAR底部填充胶1098
Feature
1) #1098 has high capillary flow to give fast penetration for the narrow gap
2) It is designed with high Tg and low CTE that provides high drop shock resistivity and excellent thermal cycle performance
3) It is reworkable underfill that minimizes the damage of components around the rework target after rework process
