++++++ I want to know the reason for the solderability problem.
What causes for that. Mohan VNK Prasd
++++++ Processes such as soldering are quite complex, and it is always impossible to offer a single cause for a problem when little data is offered. Let's start with the socket: is it tin plated, silver plated, gold plated, electroless nickel plated, or something else? Is it made of brass, berylium copper, or phosphorous bronze? Is the solder lead-free? "Dry solder" may mean different things to different readers. To me it meant the mottled crystalline look which is the result of something moving during the critical seconds while the solder is cooling. We would like to try to help, but a lot of data must be supplied. Thanks.
