Latest Patents

One of Langevin's latest patents is the "SMT passive device noflow underfill methodology and structure." This invention provides an electronic fabrication process for attaching discrete passive surface mount devices (SMD) to a substrate in a single step. The process involves dispensing a liquid noflow resin encapsulant containing flux material between presoldered pads on a substrate. The SMD is then pressed into the encapsulant, allowing its electrical contacts to make contact with the presoldered pads. Heat is applied to activate the flux material and reflow the solder, bonding the SMD contacts to the pads. The resin encapsulant solidifies, filling the space between the substrate and SMD, and forming fillets around the solder bonded contacts.

Another significant patent by Langevin is focused on extending the fatigue life for C4 solder ball to chip connections. This method and structure couple a semiconductor substrate to an organic substrate, interfacing a solder member to conductive pads on both substrates. By optimizing the surface area of the pads and the distance from the centerline of the solder member to the lateral edge of the semiconductor substrate, thermal strains during thermal cycling can be reduced.
