How to Use the Right Flux for Selective Soldering Applications
Selective soldering requires a combination of performance attributes that traditional liquid fluxes designed for wave soldering applications cannot fulfill. Statistically, designed experiments on the equipment can map relationships between flux characteristics and selective process friendliness. Performance attributes to consider include compatibility with drop jet dispensing (clogging effects, cleaning frequency, and satellite formation), spreading (in actual processing conditions, with multiple solder resist types) and soldering performance, as measured by barrel filling and defect production in challenging thermal conditions.

EMS TOP 50
Another year, another Foxconn display of utter dominance in contract manufacturing. But in what was in many respects a relatively quiet year, there was much more happening under the radar. A look back at the major trends of 2015, including the race to India by the world’s largest EMS/ODM companies.
