the first step of producing SSR: solder copper pillar for SSR PCB

the first step: solder copper pillar for SSR PCB:  weld the small copper pillar, wait for the tin to wrap it all around, then weld the large copper pillar. The copper pillar should be placed vertically and not allowed to tilt. Tin must wrap all around the copper pillar, and tin cannot drip into it. If tin drops into the copper pillar, immediately remove it and replace it with a new one. After all four copper pillars are welded, take a look again. If there are any copper pillars that are not completely covered or tin that is not covered, then solder them with a soldering iron.
