We had 4 of these machines several years ago. If I remember right the drive that aligns the board to the stencil was stepper motors with no encoder feedback. We would see the same issue if our leadscrews and linear rails were not clean and properly

I'm not sure it would explain your feed issue, but the main thing that we have found to cause problems is the two nylon gears that pull the tape. The teeth get bent, and they don't mesh together as well, causing the tape to not pull correctly. Or t

Yes. I'm at a loss as to how to best approach this. I think the giant blob of solder is just going to behave more like a lubricant than anything else. The thing is, I would like to at least try the manufacturer's recommendation once (and this bui

Sorry but I disagree The conveyor be it mesh belt or pin chain is a moving part that has caused many parts to dislodge Lack of lubricant on all the moving parts is usually the culprit I’ve also occasionally seen a bent link on a mesh belt snag & hoo

If all other tools appear to be working fine, only the A12 is having the issue. You might have a faulty tool(not within original spec). As Bruce suggested, check the A12 tool itself to see anything abnormal. If it's brand new, you might need some lub

Buy a dryer to go with your compressor. Compressed air traps a lot of water and you don't want that in your air lines on your P&P machines. Additionally, make sure you keep up with all the preventative maintenance and change out the filters as requir

It is possible. If the talcum powder mixes with the chain lubricant, it could gum everything up. Back a few years ago when I was running an SMT Quattro Peak, I was having an issue with the conveyor chain drive motor going into overload. We had to pul

Hi Marc I too have been using a fully synthetic Motor oil on Heller reflow ovens for a number of years. In our case Mobil 1 5W-50. We have a field failure problem with some 1% resistors under conformal coating where sulphates are dissolving the si

Some key data is needed 1) how often does the HS 50 machines run? 24/7? 2)How many placements are being performed? I know for a fact Siemens Siplace S/F platforms require weekly preventative maintenance. Knowing the sophistication of the HS platform

We use the following stuff from "Biral USA": BIO30 Synthetic High Temp Oil � Chain Oilers NMG-400G � No melt grease - miter gears/lead screws AS500ML � Anti-size spray - lead screws, drive sprockets, rail support L-brackets It seems to work good
