Our company is looking into purchasing an in-line conformal coating machine. We have narrowed the field down to 2 machines the USI Prism Ultra-coat 350 and the Asymtek C-740, anybody have either machine. Good points or bad about either machine? Th

We use an Asymtek C-741 with 2 heads for silicone and acrylics but no convoyer. What type of head and product will you use ?

Alex, We will be using acrylics only. We are looking for a machine that will allow us to have 20 to 30 keep out areas per PCB. How's your machine at keep out areas? Thank you for any input.

jdumont, We have a capacitor and an inductor that stick up approx 2.5", any problems with the spray nozzle working around tall objects? Thank you for your input.

No problem if you get the tilt head option. Also depending on the geography you can just lift the nozzle up and the spray pattern will fan out more. The software is really good, i think you'll be impressed.

Good idea, pick the most difficult of your PCB and watch the final result. If you can, go to each company and watch the machine how it coats your board. You'll see what is the most suitable for you.

Hi. We are designing in a 128 pin LQFP that has a heat sink in the center of the package. The size of this is 7.44 by 7.55 mm. Can anyone recommend what pad size should be on the board for this? How about stencil aperture/pattern? Thanks, Mike.

Mike, I have to inform you that if you don�t let "sales people" talk about lead-free You will experience total silence. I will let you draw your own conclusions.
