What about reducing your force and slow the blades down slightly

In some technical reports, i have recently read that when processing a PBGA, it is worth controlling the reflow temperature under 205�C. Indeed, over 205�C some people have noticed plenty of popcorn effects. Is this point really true ? Does this te

I've noticed that after we have switched to Transition Automation blades on our MPM screen printers that the stencils seem to be wearing out faster and I see a wavy rippling effect across the length of the stencil thats impacted by the squeege blade.

I have printed 1000's of boards with dozens of stencils with TA permalex blades and have not had the issue you speak of. Sorry I was not much help. Cal

What Snap-Off are you running ? I've seen this happen when a large negative Snap-Off is used. If you "contact" print (I.E. Zero Snap-Off) this tends to minimize the stencil coining. We use a mix of MPM & Transition Automation blades. I have noticed

Silly question, but, are TR blades 'exactly' the same size as MPM's and seat themselves in the holders just like MPM's? Also, different types of steel are harder (less flexable) than others. Are TR's the same? If harder (due to steel strength or coat

There appears to be less of a blade sticking out of the holder than the MPM set up. Thats something we noticed recently. We have our mechanical attack angle set at 0 degrees right now, but we are in the process of changing this setting by 5 degrees t

Jeezuz... Darby is right. High Tech Squeegee blades are a crock of BS.Don't belive the hype. Its a big scam to rake in your dough. We use .008" thick spring steel stock from McMaster. There is only one thing:The blades must be dried off thoroughly af
