I am currently having a problem with uncut legs on one side of axial components from a universal dual head insertion machine. Initially it was thought that the anvil on one side was engaging slow so I stripped down and changed the seals in the botto

Many years ago, we used to double print. The way we did it was with a rubber squeegee set to do a flood stroke, followed by a return cleaning stroke with a metal squeegee. Why?! Well, this was in the days before Laser etch, and because the chem bat

Basically, Brushing the pogo pins with dry anti-static brush will help but, cleaning it using solvents is not that advisable because it only leaves some residue that will further cause contact problems. Looking at the picture it seems that the UUT's

In screen printing the material is transferred through openings in the screen mesh. You can imagine small columns of "ink" that coalesce after the screen releases. Screen printing is also an off-contact process verse contact process of stencils. The

I have paste left on my stencil on the forward stroke. I adjusted the downstop pressure but it didn't help. Any suggestions.

Consider: * Printing: errors [ie, insufficient, excess, skipping, etc.] paste doesn�t roll in front of squeegee, paste adheres to squeegee at the end of stroke, paste does not release. * Component placement: orientation, wrong component, missing comp

This depends on the model. Most machines and turret style typically overstroke .2mm with a force of 250 - 300 grams of force. the reason for the over stroke is to place the component into the paste. This can be adjusted through part library manipul

Dek 265 GS Problem: Machine abruptly turns off. It can be in the middle of a stroke or just sitting idle. After the machine turns off we have to let it sit for a few minutes (sometimes 20) in order for it to restart. Any suggestions? Thanks in adv

When it quits printing correctly.... replace it. No, it is not after a certain number of squeegee strokes. The only way that could possibly be calculated is if your squeegee blade parameters never varied.
