Call Heller directly, and give them the oven, and relative thermal density of the board, as well as the solder paste that you're using. They'll be able to give you a baseline profile to start from (both RTS and RSS). Otherwise, use a thermocouple p

The whole process counldn't be easier. The sales reps' try to turn the whole thing into some crazy black art-its not. The stencil supplier will have their own standard 'glue dot' configurations, and 9 times out of 10 these are more than adequate. As

Hi Jay, please let us know your inputs from the seminar regarding SN100 Nihon solder from FCT. This solder seems to have a higher melting temp of 221C. It prints well and visually looks similar to SAC alloy. Have no reliabilty data though. Jay

Today, I have just finished evaluating Kester's EM907 (SAC305)lead free solder paste and found that for our applications it performs as expected. End result that I am encouraged with the results that we got. The equipment that I used: An SMT2020 to

What is the difference of formulation No-Clean Sn63 with No-Clean lead free paste? Is there techniocal data in detail for performance property of No-Clean lead free paste (for example, viscosity, solderability, tack, print life, reflow profile)? Is

+1 on what robgd3 said. It's basically the same process. The bummer is that you only have three thermocouples to give you the information you need, so placement (and attachment) is more critical. You also don't have the predictative capability of

Shane, We're assuming that the software is similar to our Heller 1800. We're also assuming that the oven has thermocouple ports, and that you have the thermocouples to plug into them. From the screen that displays the zone data, there should be a

Hi Dafe F, The edge hold conveyor was installed due to the double sided process on our new products. Remember the Stencil Printing Adhesives versus Dispensing in the forum a year ago? Well that led us to acquiring a Camalot 3800...This time it's the

Last week I had the opportunity to get a sample of AIM SN100C solder paste. The SN100C paste was very nice to work with. My initial observations was that the paste had a very light odor, much less than the Alpha UP78 paste that we are currently
