Take a look at this. Remember, these are only guidlines and can not replace any paste specs. As Real Chunks said, a profiler will be of HUGE help. We use this to determine what our top side temps are and to see if we have any problems with heat sen

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

I'd like to add something about the ECD product. During a past work term (I'm a a co-op student) in an SMA plant, I worked extensively with the Super MOLE Gold in developing the reflow profiles for high-mix, low-volume production. I was 'married' t

| I like to know under what conditions the reflow profile of a solder paste is taken? Bare board, board with the solder paste, or board with high melt solder paste? | John: None of the above. The two key variables that determine the reflow tempera

Before "Pb-Free" became an issue we were and still are using Pb-Free component lead finishes- such as on many TSOP, SSOP and QFP packages as well as caps. Components manufacturers changing the lead finish to no-Pb tend to ensure solderability with Sn

woow, slow down hot rod, hey davef, you are alright by me, good to see some one out there that has hands on experience rather than a theory nut.... any how, you need a top of the line profiler, super gold mole, or Kic.... these truly are the best and

+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

Presumably you're talking about lead free, but you don't say. Heller can probably provide you with a starting point, as rob has already pointed out, but you do need to develop the capability to perform profiling yourself. That oven should have ECD

Marc, Topside temperature is one of the most critical parameters for a successful solder process. Temp stickers are OK to use but won�t tell you the temperature in tight areas. The temp gun like Jay suggested is what I use as a quick indicator. (Rayt

The primary driver to the set points for your oven is not the board or the number of zones in your oven. It's your paste. If you need a "ball park" guesstimate as a starting point, your equipment supplier is probably the best place to start. So fo
