Dear all,
That is the first time I post in newsgroup.
I have a question about the solders. As I know the solder left behind some flux which is very difficult to clean it in large amounts. Have anyone test a solder which does not leave that spots of flux on materials? For example I try to close some boxes and I put some soldering between the external metallic box and the pcb. When I am finished I see the yellow flux be there. Some times I have to close about 100 pieces so I must clean them after. So is any who could help me ?
Thanks
