The miniaturization trend is driving industry to adopting low standoff components or components in cavity. The cost reduction pressure is pushing telecommunication industry to combine assembly of components and electromagnetic shield in one single reflow process. As a result, the flux outgassing/drying is getting very difficult for devices due to poor venting channel. This resulted in insufficiently dried/burnt-off flux residue. For a properly formulated flux, the remaining flux activity posed no issue in a dried flux residue for no-clean process. However, when venting channel is blocked, not only solvents remain, but also activators could not be burnt off. The presence of solvents allows mobility of active ingredients and the associated corrosion, thus poses a major threat to the reliability. In this work, a new halogen-free no-clean SnAgCu solder paste, 33-76-1, has been developed. This solder paste exhibited SIR value above the IPC spec 100 MΩ without any dendrite formation, even with a wet flux residue on the comb pattern. The wet flux residue was caused by covering the comb pattern with 10 mm × 10 mm glass slide during reflow and SIR testing in order to mimic the poorly vented low standoff components. The paste 33-76-1 also showed very good SMT assembly performance, including voiding of QFN and HIP resistance. The wetting ability of paste 33-76-1 was very good under nitrogen. For air reflow, 33-76-1 still matched paste C which is widely accepted by industry for air reflow process. The above good performance on both non-corrosivity with wet flux residue and robust SMT process can only be accomplished through a breakthrough in flux technology.

Austin American Technology (AAT) is pleased to announce that it has successfully completed the installation of a Mega ION® SA at KYZEN's Applications Lab in Nashville, TN. The Mega ION SA is the perfect addition to KYZEN's Applications Lab for cleaning test requiring a semi-aqueous process. The Mega ION SA rinses with de-ionized water rather than using a solvent to both wash and rise.
The Sawa Eco-Roll eliminates waste and saves money by reusing wiper rolls for printing machines. The SC-ER360 cleans wiper rolls in just 20 minutes and measures W900 x D850 x H1200 mm. Sawa Stencil Cleaners are widely used in the Japanese electronic
