High Frequency Electrical Performance and Thermo-Mechanical Reliability of Fine-Pitch, Copper - Metallized Through-Package-Vias (TPVs) in Ultra - thin Glass Interposers

Aug 10, 2017 | Sukhadha Viswanathan, Tomonori Ogawa, Kaya Demir, Timothy B. Huang, P. Markondeya Raj, Fuhan Liu, Venky Sundaram, Rao Tummala

This paper demonstrates the high frequency performance and thermo-mechanical reliability of through vias with 25 μm diameter at 50 μm pitch in 100 μm thin glass substrates. Scaling of through via interconnect diameter and pitch has several electrical performance advantages for high bandwidth 2.5D interposers as well as mm-wave components for 5G modules....

Modeling and Control of SMT Manufacturing Lines Using Hybrid Dynamic Systems

Apr 05, 2012 | L.G. Barajas, A. Kansal, A. Saxena, M. Egerstedt, A. Goldstein, E.W. Kamen

In this paper we show how hybrid control and modeling tech-niques can be put to work for solving a problem of industrial relevance in Surface Mount Technology (SMT) manufacturing. In particular, by closing the loop over the stencil printing process, we ob...
