Abstract: A DIMM connector having reduced crosstallk includes ceramic particles having a high dielectric constant and/or composite fibers mixed into materials used for fabricating a connector housing of the DIMM connector.

Abstract: The present invention provides low stress non-hermetic conformal coatings for the protection of microelectronic devices, such as a Microelectromechanical system (MEMS) based multichip module from adverse environments. The induced stress from these two coatings due to the thermal cycling and manufacture processing will not cause any influence on sensing accuracy of the piezopressure sensor or similar functional MEMS devices. Furthermore, the conformal coatings have the merits of low glass transition temperature, good elongation, low moisture uptake and mobile ion permeation, room temperature curability and good contamination resistance to the jet fume, which promise a high reliability for the aerospace and avionics application. One conformal coating comprises a composition/formulation containing a rubber, siloxane or urethane oligomer modified epoxy and an organic hardener, and optionally an organic diluent and a curing catalyst.

Abstract: A depolymerization cleaning solution, and method of using such solution, for removing undesirable thermoset polymer sealants residing on electronic components to provide such components with a clean seal surface for a subsequent rework process. The depolymerization cleaning solution includes a premixed metal hydroxide or amino onium salt saturated solution having a surfactant. It is particularly useful for the localized deposition and removal of thermoset polymer sealants, such as polysiloxanes, within sealband areas of the components, which have been applied on such components with different levels of chemical inertness. The material set and method disclosed in the present invention are the basis for a low cost electronic package adhesive rework process.
