Hi Everyone, I am new to this forum. I have posted a similar question on this subject (Chipmounter Plancement Speed). Does the 60% inclusive of the PM and Downtime ? I also find that line balancing also plays a part. For example the Universal GSM II

Hi, I wanna know if I immerse my fully populated PWB in a solution with 90% IPA and 10% De-ionized water at 80'C, will there be a problem or issue? Will my board or components be damaged? Will my PWM Mask peel off? What are the possible damage that

I know it's a dumb question but have you tried swapping feeders or getting them all checked? (Possibly not indexing accurately). I only suggest this as the CP's are turret, and have to take the component where it is presented, with no adjustment,
