Reflow profiles are based on the product and materials you are soldering. You need profiling software and a data logger.

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

You can, and for small parts you probably won't see much difference between body temp. and lead temp. For QFPs or PLCCs there will be a much greater delta, though. I'd be more concerned with the small surface area you're making contact on (spherica

Sarry, Word on the street is that your profile will have to be hotter, maybe up to 20C hotter, I have trialled lead free. The sales guy said, "Right, lets reprofile your oven ! I said, "No, lets try it as it is.....! The results were fine, as the

That's why you have to read between the lines of any article. Even with data from a paste manufacturer, it's still a bit fuzzy on how their paste will actually work. Not many companies have their data that solid, so it's better to experiment and me

As I stated, the reply was direct from Indium, (thanks to Rich Brooks). The information regarding cool down rates should come from your paste supplier; not an oven supplier; not a generic article on lead free. I just went through the data sheets from

We do both our ovens once a week. If something looks out of tolerance (we've developed acceptable tolderances based on many recorded profiles over time and oven mfg. specs.) we wait a couple hours and try again. The recorded data over time is very

We verify oven profiling once a week on a scrap board and enter the data in a SPC Chart. This works out great and I have not noticed any problem. I also like the idea of sending the Profiler through the oven with the thermocouple sticking out to meas

Hi, We used to manually profile by comparing logged temp numbers and matching the paste profile. But we got a KIC and it's software was so much better we got a good reduction in rework and we have almost no first run faults now. I would recommend on

In answer to your questions. (1) pls can any body throw some light on the reflow profiling? Reflow profiling is the process of confirming that you PCB's that pass through your reflow oven are produced within specifications provided by solder paste
