As the IC assembly technology fast developing in the modern electrical industries. Demand of high performance electric product is glowing up day by day. New generation of the hybrid IC assembly package has become the major role recently. In order to prevent the package defects occurring in end customer sites, in this paper we try to improve the IC assembly method by using a totally different process to fix the passive component on a BGA substrate. We found that the passive component can be proceeded the current gold wire bonding process.
In case of the Hybrid BGA with the current passive component attaching process, we can find the thermal effect during the surface mount process. Since the solder can be melt every time during each heating process. Therefore, we plan to improve it without solder attachment. The new improvement is to fix the passive component by a non-conductive thermal cure glue. The glue can be done in one time cure, thus the further process would not influence the quality of passive component.
However in the evaluation experiment, the component coated by Gold is the best choice, but we intend to just put it in a comparison model because of the cost consideration. Both works on passive component coated by Gold and Solder were proved. The customer support for the further study on the real products is suggested.
