"Polymide Films absorb a great deal of moisture. Polymide laminates must be baked at more than 1 hour at 100'C or better for a double sided PWB prior to exposing the laminate to elevated temperatures such as that required for soldering. Moisture abso

I used an Ultraprint 2000 so if that's what you use then maybe I might be able to help. First, I'm assuming that you've already passed the Teach New Board section. This is board dimension, X and Y boardstop, stencil/squeegee heights and strokes. If

Hi Pete, Thanks for taking the time to respond. My experiences with Mydata would differ from yours, but as in life, different machines are for different circumstances. We have many low volume customers that love them - they are easy to use, upgr

Hi Grant, The purpose for allowing the solder paste to reach room temp before production is to reduce the amount of water absobtion from the air. (e.g. a cold glass of water "sweats" on a humid day)The purpose for mixing is to make the viscosity more

Hi, It's removed from the fridge, and the tube is loaded into the stencil printer, however it's winter here right now, so it's still quite cold. It's Australia, so when I say cold, that's relative, however the room can be about 10 dec C in the morni
