So, tonight I decided to test the current on another section of the same strip with the same SMD number as above, which is 39. However, after soldering the wires to the pads, I was getting a short between the 12+ pad and one of the other pads that I soldered wire on, two pads away from the 12+. I took a magnifying glass and looked and looked and could not see any bridges or stray pieces of wire or anything. I cleaned it again with 99% iso Alcohol and still couldn't see anything.
What must have happened is the pad somehow made contact with the other pads underneath the solder joint, but I don't know how. I had to kinda push down on it, but it did have a short.
Thinking aback, my new strip did that on one pad, and I made sure there were no stray tiny wires or anything else between any of the pads, and tested again. I didn't get any continuity and so I triple checked it and pricked all over the joints, but not continuity where it should not have been. I called it good. But now I'm doubting the new strip is sound, even though I ran it with current and had no problems, except for why this thread was started (higer than calculated amps). After tonight, I'm scared to use it. I'm doubting all of my work on this new strip now.
I read somewhere that when you cut an LED strip, sometimes the cutting alone can compress the strip pads, and they can short that way. Can anyone explain how or what may have happened tonight?
Anyway, after checking and double checking I pulled up on the 12+ wire, and part of the pad and the wire came off. It was like it was just delaminated. The other connections I also tried to pull them part, trying to understand where the weak link was, but they held firmly until the strip itself started to tear.
What the hell am I doing wrong?
