Could be lots of things. With limited information about temperatures, solder alloy, and cleaning; we'll swing for the fence that you got these solder connections very hot. So hot that Pb oxide is dominating the solder joint surface instead of the

Hi Ralf, This discoloration may be re-oxidation. Fluxes are supposed to do three things (1) remove oxide, (2) promote wetting, and (3) protect surface from reoxidation. The solder paste possibly is not protecting from reoxidation. Best Regards, St

Many customers looking for IC shipping tubes value the appearance of the packing tube. They will feel that if the appearance of the IC tube does not look good, the quality will not be very good, so the first impression of the appearance of the Antistatic ic tube is very important. So what are the factors that affect the appearance of IC tubes?

The oxide layers are known as wetting inhibitors in component and PCB metallizations. The oxide acts as barrier that prevent the tin diffusion from happening. Besides, in corrosion studies, the role of salt residues -with Cl ion- on some metals is known as being promoters of oxidation or corrosion. On the other hand, most of corrosion studies with tin metallization are focused mainly on the corrosion resistance of tin alloys, but little has been done respecting to the influence of salts on tin metallization wetting. In this paper, a series of experiments was carried over to know the influence of specifically NaCl on BGA wetting given Head in Pillow (HiP) as result.
Lyra Reflow Oven is a soft soldering that realizes the mechanical and electrical connection between the solder ends of surface mount components or the pins and the printed board pads by remelting the solder paste pre-distributed on the printed board
