As one of our small batch processes, we place BGAs on PCB without using solder paste. We apply tacky flux to a predetermined height on a pallet, "dip" the BGA into the tacky flux to wet the solder balls to the set height, and then use a BGA rework st

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,

Look to: * Your flux supplier's recommendations to baseline your recipe [similar to using your paste supplier's recommendations for setting your reflow recipe] * 7530 'Guidelines for Temperature Profiling for Mass Soldering (Reflow and Wave)' for gui

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

It shouldn't be any issue if you measure the top reflow settings using bottom profile board & the results are OK. To common the reflow profile, both bottom & top profile measurement are taken & analyzed. This, too, can be applied, even for differen
