I have four IP3�s all that require different height board support pins. Is there a way to adjust the table height so all of the machines are the same?

hi experts, need more info on what's happening with the LPI Solder Mask on an FR4 PCB during reflow of both Leaded and Lead Free Process? Do they become soft as well while exposed to the extreme temperatures? regards,

Then how the hell do they expect you to set up your processes?

Find out what the Tg of the LPI is. Below - rigid, above - flexible.

openings, rectangular no home plate. pad spacing don't have data right now. the problem is those products have from 1 year to 5, running constantly whitout problems and observe the issue around 3 lines no matter of the product.
