Hi Russ I happen to come across a article about reflow profile. Other than Ramp-to-spike(RTS) & Ramp-soak-spike(RSS), its introduce a new reflow profile & call it LSP. Is it possible to give me your email address & I will send the article to you?

Dear all, I would like to learn from all regarding purpose of each profile stages, such as preheat, soak, peak cooling. At what stages, flux start to be activated? Thanks for your time,

Hello all, Our guys here still have some questions on the "optimized" profile which sees a more moderate ramp up straight to reflow temperatures versus the conventional profile which has a plateau at around 150 Celsius. If the optimized profile can

Hello again.... I have been reading up on profiles and how to set them up for different results. I now have an upcomming job with some strict guidlines on reflow. I was wondering... if I were to email a pic of my desired profile could someone out the

Background: We use a thermal boards to setup/profiling the reflow oven for pilot run.and then daily verify the reflow profile with this thermal board.Now we phased into LF production,and the LF thermal board can only withstand 25~30 times reflow excu

We have enough history to know that frequent profiles are a waste of time. We check the profile once a month, after any significant maintenance, and after a changeover. Other than that we rely on the alarms on the individual zones.

The correct Frequency to verify your reflow profile is about one week except when you replaced the part,equipment,the channel setting of the oven or running pilot lots.The period of the Themal board is around 50 times.

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
