You need a KIC profiler whitch is able to find optimal profiles for your boards. The KIC works very well with the Heller ovens. With the KIC is also possible to find one good profile for different boards. Get in contact with KIC +1-858-673-6050

Let me be more specific about my dilema. We have used a vapor phase reflow process for many years. We just bought a Heller 1800 this year (2000). We may very well be able to run all 600 very different board types we build in 10 recipies on the Hel

Sounds like a true IR guy to me!!! Your profile should reflow solder on the board properly to produce a reliable product for your customer. If that requires more than one proifile, so be it!!!. That being said, we went from hundreds of IR profiles

Russ: you could divide your 600 in let's say 10 or more categories,category #1 could be the thinnest thickness and smaller board size and smaller components;category #2 thinnest thickness smaller board size and mixed small and big components; and so

If you can divide your boards into different categories it allows you to determine a different starting profile for each category, based on size, # of layers, etc. When you get a new board to profile you'll have an idea what settings will get you clo

My agreement with all this started by Arturo's message... Just as a reminder, I guess he suggested to have still "one profile per board" which I completely agree... So, Board #(1,600) could be using a Recipe #(1,10) but it should still be saved as

If I were you, I would divide my boards into categories...and I'll categorize them by their components e.g. Bds with BGA, with QFP, Bds. with plain chip components...and so on...this is to create a recipe for each components with QFP's, BGA's etc...t

We just bought a new Heller 1800 EXL reflow oven for reflowing SMT boards. We us a low temp RMA solder paste with 2% silver. Everything we build is to IPC Class 3 specifications. We have approximately 600 different types of circuit boards we build

Let me see if I've got this straight...rather than hook up a MOLE or a KIC profiler to each and every board (600 P/N's in my case), most people are making judgement calls based solely on how similar a board looks to another board, for which they have
