The only part, which could cause component misplacement on the rotary heads of the Siplace machine is the vacuum valve. I don�t know the official name in the part catalog, but I use to name it plunger. The plunger is moved in and out by a miniature s

First of all, I am not familiar with the machine you stated. But there is something you should check out. That is if the nozzle tips having solder paste stick to it or not. If nozzle tips having a fresh paste stick to it, the component might not a
