We had a cooler fail once, before we had any SMT. Auto-insert was at the far end of the building, at the end of the compressed air line. When the Unimod (dip inserter) sprayed the operator with water when the pneumatic table rotation motor fired up

I never thought about painting our copper piping. I always thought the patina that covers the pipes adds a bit of history and class, ya know an antique-feel, to the shop. I was in a shop years ago that used PVC piping for their air. From looking a

Hi, It's much better to add the cooler after the tank, as the tank will condense a lot of the water before it even hits the cooler and goes out. It's a much better system to have the tank between the compressor and then the cooler. The air also get

Copper is best! I've seen troubles with black pipe - the pipe is not always clean on the inside and debris or mill scale makes it into your equip. eventually. We've also used PVC to get by/quick fix and we always ended up blowing a fitting or even

On our new shop we used iron pipe in the walls and attic and copper ever where else that can be easily accessed. I saw a pvc material at a trade show years ago that was rated for air lines. With their demo material they could fold it and drive nails

Hello, During a recent customer audit, one of their auditors asked if we measured airborne particles in our SMT operation area. Within their operations, they mentioned a concern when placing micro-BGA's. My question is: do some SMT lines use a pseudo

Only use the shop air if it is clean and dry. I know from experience that one can get water and a little oil from the compressor in the air lines. We are in a drier climate with humidity levels in the 25%-35% range on average. All we do is let the

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

You want a big enough storage tank to smooth pressure. Figure out what size pipes you need and go a size bigger. Make a loop of the pipes with shut offs. That way you can shut down any section and still have air to the rest of the air line. Run the p

Thanks for your reply. I 've tried to clarify and answer your questions. The water soluble paste used is WS3060, type 4. The boards are sent through a inline di cleaner after reflow. There is a hot Di waterwash, rinse and then hot air to dry the wa
