Hi,
I have a Wii mother board with most of the vias covered with solder mask. I’ve been practicing on unused vias to scrape away the solder mask and try to tin them. Unfortunately I can’t seem to get the hang of it, as out of 4 vias I have tried tinning, only one worked out.
Here I scraped two vias, I thought the copper looked shiny enough and tried tinning them but solder doesn’t want to stick properly. To make sure I was using my iron correctly I tinned the test pad just above and it worked. The via on the bottom right, next to the traces, I am not sure if the tinning worked out properly.
another example of a « tinned » via:
I am using this small file for scraping:
I must be doing something wrong.
What do you guys use as a technique to properly unmask the vias and solder to them? I’ve watched a YouTube video but the camera was a bit too far from the via to see the scraping up close.
