IFTLE 313 IMAPS 2016 Part 2: JCET & Qualcomm Discuss CPI for Die in FOWLP

By Dr. Phil Garrou, Contributing Editor

Post Thanksgiving IFTLE mean an update on Maddie (L) and Hannah (R). The family spent Thanksgiving in NYC where I grew up. The rock behind them is from the meteor exhibit at the Museum of Natural history. Speaking of rocks, can anyone identify the rock on the right?

Lin of JCET discussed CPI (chip package interaction) for 28nm die in eWLB fan out packages. JCET proposes FOWLP as the 3rd wave of packaging:


They proposed the following current and future eWLB solutions:


They have evaluated electrical CPI and CBI (chip board interaction) for their FOWLP technologies with the following test package and found no problems.
