/diy/ - Do It Yourself

>>2777548
I realize it's about a week later (had a lot of stuff come up), but I finally did a quick test just now. Using one sacrificial LED, I scraped the back with a 3M sanding block (not sure of grit, but it seems relatively fine). I had mostly no issues with getting solder to apply to the pads when isolated, which leads me to some hypotheses:
>The pads developed some kind of film or melted invisibly to plastic in storage (was a warm environment)
>This seemingly invisible film was only removable by lightly scraping it away (which my too-soft tweezers and eraser heads could not do effectively before)
I'll go ahead with lightly sanding the pads of any LEDs in this set I'll be working with. I just hope it doesn't make it more vulnerable to overheating when soldering bridges to the PCB. I hope this will be of use to other anons in the future.
