An experiment on the early stages of intermetallic compound layer growth during soldering and its theoretical analysis were conducted with the intent to study the controlling factors of the process. An experimental technique based on fast dipping and pulling of a copper coupon in liquid solder followed by optical microscopy allowed the authors to study the temporal behavior of the sample on a s...

The aim of this study was to determine the specific agent responsible for eczema on the forearms of 2 electronic assemblers who cleaned out a flux-spraying unit once a week. Soldering flux can be a source of skin irritation as well as allergy. Patch test with dried flux residue (as is) and rosin in dilution series of 20%, 10%, and 1% in olive oil was performed. Readings were taken on day 2 and ...

objective(s) to determine the potential toxic effects of manual soldering flux cored solder wire on lung of the rat as an experimental model. materials and methods a total number of 48 adult male rats were divided into experimental (n= 30) and control (n= 18) groups. based on exposure time to solder fume, each group was further subdivided into 2, 4 and 6 week subgroups. rats of experimental gro...

Resistance spot welding is used in the assembly of automobile bodies. The use high tensile strength steel plates bodies expanding, and there a need to develop process that improves joint per resistance weld point. To improve weld, can be combined with other joining methods, such as WeldBond method. As an additional method around nugget, than using adhesives method, brazing obtain strong without...
