We are testing SAC paste for thru-hole components in the 2nd reflow process. The solder joint is alright but some problem encountered in FR1 or CAM2 PCB after multiple times of reflow due to the temperature. We are very interested in Zn or Bi-based l

Dave, I know that black pad isn't solderable by any alloy. But it's still justified to relate the nickel barrier plated boards to lead free. Before lead free the predominant board plating was HASL and OSP. These platings disappeared with the switch

Hi, I think that the time depends on the type of stainless steel, temperature and solder alloy. For example, one of our machines is delivered with 316 stainless pot and alloy SnNi. It worked six months (120days*16hours = 1920hours) and aft
