I recently had the same problems, solder bridges on every thing I made, different customers boards, etc. I wave with no-clean flux. As I sorted out problems (pin holes, blow holes, splatter, etc.) I found a lot of variable factors. I changed flux,

I agree with DDave, You have something else wrong! .100 dips with .05" lead protrusion should not bridge (in fact I would think that it would be almost impossible). Tell us about your machine, (laminar flow, A-wave, etc.., size of nozzle, wave heig

On behalf of the SMTA International Technical Committee, we invite you to submit a 300 word abstract of your research for the 2016 SMTA International 2016 technical conference in Rosemont, Illinois. Papers should describe significant results from experiments, emphasize new techniques, and contain technical, economic or appropriate test data. We are looking for papers on a variety of topics related to electronics manufacturing including advanced packaging/components, assembly, business/supply chain, emerging technologies, harsh environment applications, PCB technology, and process control. Materials must be original, unpublished and non-commercial in nature.

The selective soldering process has evolved to become a standard production process within the electronics assembly industry, and now accommodates a wide variety of through-hole component formats in numerous applications. Most through-hole components can be easily soldered with the selective soldering process without difficulty, however some types of challenging components require additional attention to ensure optimum quality control is maintained. Several high thermal mass components can place demands on the selective soldering process, while the use of specialized solder fixtures and/or pallets often places an additional thermal demand on the preheating process. Fine-pitch through-hole components and connectors place a different set of demands on the selective soldering process and typically require special attention to lead projection and traverse speed to minimize bridging between adjacent pins. Dual in-line memory module (DIMM) connectors, compact peripheral component interface (cPCI) connectors, coax connectors and other high thermal mass components as well as fine-pitch microconnectors,can present challenges when soldered into backplanes or multilayer printed circuit board assemblies. Adding to this challenge, compact peripheral component interface connectors can present additional solderability issues due to their beryllium copper termination pins.
