I have an ap-25 and wish i had gotten the UP-2000 instead. How's that for an answer? The main difference is that the ap-25 uses linear motors and air bearings, whereas the up-2000 uses ball screws. The linear motors are faster, but the whole thing i

From what I remember there is a "snap off" setting in the AP25, where you can set the separation speed & I think it may also vibrate the board a little.

At times we have had this problem with our AP25 due to one of the conveyor belts slipping. Load a PCB and check to see that both conveyor belts are running at the same speed. If not, tighten the one that is dragging. Hope this helps.

havfe you tried all paste manufacturers? Dog ears are usually from a little sticking to the aperture walls. this is usually the result of stencil design and or table seperation speed.

A UP2000 is a great choice. I'd avoid the AP family from MPM. It's not that they're bad, per se, but the air bearings make it fiddly, maintenance intensive and a giant air hog, and you don't need the speed.

Once again, it isn�t the process problem. It�s machine problem. I�ve tried to change all of the parameters: printing speed, printing pressure, snap-off speed, snap-off distance, etc. No any effect. Defect still exists with different process parameter

What are the recommended stencil apertures for a TSOP40. Lead pitch 0.48mm & lead width 0.21mm. And direction of squeegee print over the aperture? Recommended Stencil thickness? Recommended aperture reductions? Recommended pcb pad sizes? Recommended

I found the problem... the vx cable trunking was the wrong radius, so when the axis was moving at slower speeds to read pre stop position, the axis was not reading the platen correctly due to extra downward force.. Ive now replaced the trunking and

I assume your vacuum suction is good. Is this an above mounted board stop sensor? -Make sure it is finding the correct fiducial and not a similar object nearby. -Try physically moving the X-axis to check for backlash. There should be no movement.

A couple years back we were looking at going to an enclosed solder paste printing process, similar to the ProFlow, Crossflow, or Rheometric Pump. We have older MPM AP25's with a custom transport. Speedline told us that in order to add the RheoPump,
