I always go with SPF 50+. But, to be honest, there is not *that* much difference on a daily basis from SPF 25 to SPF 50: To figure out your level of protection, divide 1 by the SPF number.That equals the percentage of rays that are allowed to pass through. So SPF 25: 1/25 = 4% of rays pass through.SPF 50 = 1/50 = 2% of rays pass through. always go with SPF 50+.

DESOLDERING is the process of removing soldered components from a circuit made on PCB. Desoldering pump along with the soldering iron is used for this purpose. A desoldering pump also known as solder sucker is a small mechanical device which sucks the liquid/molten solder from the joint where the components are mounted.In order to desolder a component from the PCB, we first heat up the solder joint with the soldering iron till the solder liquefies/melts.his process is repeated until all the residue solder is sucked by the pump and the hole on the PCB is clear to solder a fresh component. Above image shows a desoldering pump-head, trigger and button of the soldering pump are marked.
