I have been having many problems with the solder blob on my McCapsule. It seems to go bad, and must be remelted every 2 weeks or so. I have removed all of the solder twice, and replaced it with new solder, but every 2 or 3 weeks; the light starts flickering until I remelt it. Does anyone notice this with their McCapsule or LE? What type of solder should I use? I know that basic rosin core electronic solder was not designed for surface contact. And has anyone come up with a way to replace the blob with something else?
