I have many hundreds of AMD CPU’s with matrix of plated pins about 1 1/2 mm long on face. How best to remove and use AP? Thinking about placing them on a hot griddle then scraping pins off. Would tin from solder interfere with dissolving the Cu out?
Remove the Tin first with HCl, then go to AP or Nitric.I have many hundreds of AMD CPU’s with matrix of plated pins about 1 1/2 mm long on face. How best to remove and use AP?
