There are instruments from ECD, KIC and Datapaq that are used in addition to classic profiling for oven thermal management and they also have some very efficient prediction software for profiling. I am not an advocate of common profiles. Most boards

Hello, On customer want to make a aluminium board. It will have SMD Led on it. Like I never "played" with this before can someone tell me what I know to know on that new thing. What kind of reflow profile we need. What just I be aware of, is

I have the same problem. I made 3 standard profiles on a 6-zone oven, but always advice to make (or at least verify) a profile. But if customers don't want to, I point at the risks, and choose a slightly higher profile to be on the safe side. If you

Hi All Does anybody have done the profiling board life time experiment? What is the proper life time of FR4 profiling board? How can we know when the profile board or thermocouple should be change?How to use dummy board instead of using gold/real

yngwie, are you getting a wave from the customer to say it's not your fault you fried the parts? Profiling's one of those things that is a pain to dobut it's one of the most important factors in the assembly processes. I've read and seen instances w

One thing you should do is characterize your reflow oven, run profile boards of various densities, say 2 gm/sq.in. to 10 gm/sq.in. Adjust the oven settings for these various boards to acheive your standard profile based on your solder paste manufactu

Hi Yngwie Have you got a reflow oven yet. If not, forget about complicated profiling with test runs or reflow trackers. We've got a nice oven with integrated temperature-feedback system. You build any profile you want and the oven will adjust its hea

Hi guys... Has anybody hv an experience with using a common or standard profile to reflow high mix brd ( say, low, medium and high )?. The reason for asking is that, we are running high mix low volume, and materials that were consigned is exactly as

One more thing I want to add. Don't turn this into some big deal. Its not atom splitting, or black majic.Bottom line is that you are going to be doing some experiments to prove it to yourself and whomever else requires the data. Profiling is time con

We had no problems reflowing an assembly on Bergquist Thermal Clad. The assembly was small. So, we built it on a 8-up fixture. It stayed in the fixture from screen print, through pick and place, and into reflow. When the fixture came out of the r
