Hi all,

I have been installing a back light for my gameboy advance but I have
created a few dry joints, I am going to order some new equipment to
make it better, some braid solder sucker, new solder iron and a
multimeter so I can clean it up start again then test the new joints.

What I would really like to know is how can I test a solder joint is
perfect/good using a multimeter? Or do I need some other equipment?
Thanks
Grant
