What we have found after using the machine for a while is that its difficult to set up most odd / uneven parts. The best way we have found is use the trimmer package and then use the rough check feature, that seems to work well with most things.

It is only available in the trimmer package, its a tick box, not sure exactly how it works but it just does a rough check of the part, not very good for fine pitch / very high accuracy needed.

I would recommend not to mix leaded irons to do non-leaded rework. Especially, if you are working on ROHS compliance project that will create contamination. Weller and Hakko still have tips for leaded soldering tips, you can chechk on their web sites

I need support to find out a good compact depanelling equipment that can be setup in a work cell as part of the final assy process for PCBs with scoring groove. If someone has experience with something similar any suggestion of guidance will be helpf

The 237*C is under the inductor with aTAL of 48s. I worked on the profiles this morning an got the max temp up a few degrees and the TAL to 62s. I will check the body temp of the Elec caps. The rest of the board has a max temp of 247. Thanks Gm

Gary, We are missing something here. I see no evidence of reflow at all. If you have a thermo couple under the inductor, 237 deg with a TAL of 48 seconds should work all day long.(even though it may be on lower end of process window) SAC melts at 21

I drilled a small hole from the other side in order to get my thermocouple under the inductor pad. I did not have anything on hand to fill the hole, so I covered with kapton tape the best I could. I suspect that is why it looks like it should work.

Ahhh...now this makes sense. Glad you found the issue. Gary, try using aluminum tape to secure thermocouples. It works much better than kapton in my opinion. KIC sells it, but I'm sure it can be found elsewhere.

Thank you all for the posts. From all I read lately I will probably try a different solder paste and if that doesn't work I will go for a flux feeder. I will keep you posted.

Interesting idea the sprite sugar/water mix.... I found a spray on BBQ cleaner which worked pretty well, but is a little sharp on the lungs! Peter
