Effect of the soldering atmosphere on the wettability between Sn4.0Ag0.5Cu (in wt.%) lead-free solder paste and various substrates
The ‘‘degree of wetting,’’ which is related to the contact angle (h) between the molten solder and the substrate, is a useful parameter on the solderability process control. The contact angle, however, is strongly dependent on the type of substrate surface finish and used atmosphere (inert or non-in...
