Latest Patents
LaBranche's latest patents include innovative thick film resistor paste compositions. These compositions are designed to include a resistor composition dispersed in an organic vehicle. The resistor composition consists of 3 to 60% by weight RuO conductive material, 5 to 75% by weight Ag conductive material, and 15 to 60% by weight glass frit. Additionally, it may contain up to 10% by weight copper oxide or precursor and up to 20% by weight bismuth oxide or precursor. When printed to a dry thickness and fired at temperatures between 750°C and 950°C, the composition achieves a sheet resistivity between 10 and 10,000 milliohms/square, with a hot temperature coefficient of resistivity of 1000 ppm/C or higher. Furthermore, the fired resistor composition can achieve a resistance thickness ratio (R) value between 0.75 and 1.50. Another notable patent focuses on thick film conductor compositions that exhibit improved adhesion and solderability due to the addition of a crystalline material from the feldspar family.
