Cameron, I am burying the thermocouple in high temp solder on the solder pad of the area I want to profile.

Does anybody have any advice on how to get a decent profile out of a 4 zone IR oven? Should top heat and bottom heat be proportionate? Are there any tricks to use?

How are you attaching your thermocouples? When using HT solder, the solder/TC surface of the joint can be reflective. This condition coupled with the IR can give you false temperature data since some of the heat is reflected away from the TC. Le

Hi, I think using a epoxy glue will be a more approriate process for a IR oven than kapton tapes or high temp solder Comments ?

Unless you have a reason, set your top and bottom to the same temperature. Tip: Don't run dry cleaners bags through the oven. Tell us about: * Paste you intend to use. * Specifics of your oven, including length of each of the heating and cooling zo

Hi, I can give you a few steps. 1. The solder paste. Take the profile that manifacturer gives for the paste. 2. Use termocouple to measure the tempereture. Put PCB and measure the temperature in equal terms. 3. Compare your profile to manifacturers

Dave, We are using Kester Easy Profile 256 No clean Sn62Pb36Ag02. The oven itself is a Dima SMRO-0252 which is a short oven, it has 13" of preheat, 13.5" of soak, 6.25" of reflow, and 10" of cooling on the way out of the oven. We are soldering multi

Call me wet behind the ears!!! I'd kinda like to see you refine your processes on your products before you go-out drying-out your ears on someone else's products. The worst contractors in the world seem to be those with their own product lines and

Something else to keep in mind when you reflow using an IR (non-convection) oven. IR reflow is more susceptible to variations in board mass and coloration than convection ovens. Hi mass areas and dark colored parts will cause more variation in your
