Abstract: A system and method for implementing an electronic circuit for protecting electronic components from ESD. A PCB or IC may include an electrostatic discharge protection layer having a first and second conductive layer separated by a semi-conductive dielectric layer. Further, the PCB/IC may include a protected node coupled to the first conductive layer and a current-shunt node electrically coupled to the second conductive layer, such that a signal at the protected node that is below a threshold magnitude propagates through the protected node in a normal operating path and a signal at the protected node that exceeds a threshold magnitude is diverted to the semi-conductive dielectric layer to the current-shunt node in a current-shunt path. In this manner, existing layers of a PCB/IC may be used for both ESD protection and other functions, such as ground planes or battery plane by isolating the specific sections of the layer for its intended use.

Abstract: High performance semiconductor devices, such as those used to package microprocessor integrated circuits, demand materials with excellent electrical, physical and chemical properties. Polymethylpentene (PMP) compositions provide resin substrates for high performance devices with a material which has a low dielectric constant and a low dissipation factor. In addition, PMP has very low moisture absorption, and good mechanical stability under repeated thermal stress, which will help keep the device from cracking and warping during high temperature assembly processes and constant use.

Abstract: A no clean thermally dissipated soldering flux is shown which includes camphor as a flux base, an organic activator and an organic diluent. The camphor provides a tacky yet fluid medium which is thermally dissipated during the flux operation and leaves no undesirable residue which would require a postcleaning step.

Abstract: A water soluble soldering flux is shown which includes gum arabic, modified polysaccharides and other natural resins as the carrier, an organic activator and water. The carrier provides a tacky, yet fluid medium capable of holding precisely aligned electrical components during solder reflow and allows aqueous removal of the flux after reflow. The flux composition can be used to solder precisely aligned integrated circuit chips onto a circuit board.
