Does anyone know where I can find good rule of thumb information on soldering/brazing. I am most interested learning the maximum recommended CTE mismatch between two different materials that thermally cycle between 25-100C.

Sounds like someone aimin� fo tha big hurt, if ya axes me. Two spots to place your lawn darts are: 1 J Hwang in "Modern Solder Technology � " states (p.354) that " � extreme CTE mismatch between silicon IC (~2) and the PCB (~16), solder connections

Indium Corporation expert, Andreas Karch, will present at the IMAPS Autumn Conference, Oct. 18-19 in Munich, Germany. At the conference, Karch will deliver his presentation entitled New Solder Alloy with Extended Temperature Range for High-Reliability Applications. He will review test results that demonstrate how a new alloy excels in harsh environments, including wide temperature range and high CTE mismatch. Karch will also share data from existing application qualifications.

In order to meet the increasing demand of device miniaturization, high speed, more memory, more function, low cost, and more flexibility in device design and manufacturing chain, underfilling has increasingly become an essential process for the good reliability of electronic devices. Filled capillary underfill has been selected for use in package-level where there is large thermal stress caused by CTE mismatch issue, but the underfill is usually not reworkable. Unfilled capillary underfill has been used for board-level application such as BGA/CSP, POP, WL-CSP where there is need for mechanical shock resistance, the underfill is usually reworkable.

thermal expansion (CTE) mismatch between the package and the PCB [20, 21]. The CTE of the PCB was measured using a thermomechanical analyzer (TMA) and the composite coefficients of thermal expansion of the 192CABGA and 84CTBGA packages were measured using
