The present invention features a novel design for a fiducial and pin one indicator that utilizes a single solder resist opening in a die mounting substrate to perform the combined functions of prior art fiducials and pin one indicators. Methods of fabricating a carrier substrate and fabricating a...

Solder mask, also called solder resist or solder-stop mask/coating, is a thin layer covering copper traces without necessity of soldering on a printed circuit board (PCB) on both top side and bottom side to help ensuring PCB reliability and high performance. Resin is usually selected as the ...
In all cases, the SMD pad SRO (solder resist opening) was 0.45mm. To compensate for solder wetting down the pad sidewall, the NSMD pads on the hybrid designs were slightly smaller to produce a similar ball height. These packages were daisy-chain test vehicles with pairs of solder joints ...
