yeah...I never had airflow volume problems with Hellers. When I had to build the system I was referring to, we had an old Speedline oven, and the way it was configured if you didn't provide enough airflow to the outer cavity, the blowers would overh

I agree with the two other replies. Left alone, it is a defect. If it's just excess adhesive or coating, you can use IPC-7711/7721 'Rework, Modification and Repair of Electronic Assemblies' for guidance on removing. Section 2.3.1 explains how to te

Dave, Thanks for your responce. I think I can manage to solder components by hand. But I am trying to find out an alternative way to solder them. The distance between leads becomes very small and if solder gets in between them I will have hard times

I got my hands on a used, refurbished machine out of China, which didn�t look quite as advertised. Machine plates, logbooks and other documents are missing. According to the machine supplier, the plates are swapped from older machines to trick custom

First, where the temperatures that aare mentioned in the original post measured? Second, it sounds like the PdAg component terminations are not seeing enough heat [your soldering iron touch-up proves this]. Your 232*C peak is the absolute minimum s

TBH I think perhaps the OP deserved it, there is perfectly good explanation of Reflow and Process Window Index on Wikipedia for starters and if you want more all sorts of FREE specialist papers on things like reflowing flex circuit, lead/lead free et

https://www.jrpanel.com/R The heat generated by electronic equipment causes the internal temperature to rise rapidly. If the heat is not dissipated in time, the equipment will continue to heat up and the components will overheat and fail, resulting

I'd like to add something about the ECD product. During a past work term (I'm a a co-op student) in an SMA plant, I worked extensively with the Super MOLE Gold in developing the reflow profiles for high-mix, low-volume production. I was 'married' t
