Many years ago (20+) we did this by preassembling the 2 parts into a mini leadframe with high temp solder paste, which was a pain but then they could be dropped in trays, surface mounted and hit the line clean. I'm guessing you have a low value cap

Mike, The dispensable solder paste is ordered separately from the printed paste because it has a higher flux content. I would not feel comfortable mixing liquid flux into the printable paste. Ask your paste vendor if they have a dispensable version.

At a past employer we stacked caps and resistors quite regularly. As some have suggested a dispensable paste was used and dispensed by hand and then the stack was placed. At first it was placed by hand, but then we were able to program our Mydata to

i had 2 pumps xD also, propeller size can give you a clue. do some research on turbines of any kind, its same principal. you can have someone check it for you on same machine, i'm sure someone will help.

Hi Zac, In looking at your photos, you may not be having a problem with your machine, but with the solderability of the PCB. I've zoomed in to an area that looks to me like the solder has de-wet from the pad. The leads appear like it almost has a fi

Hi again Zac, Nickel appears a little darker and won't have as much of a deposit as it is plated on. But if you want a quick test you can buy a little kit from Amazon that tests for nickel. Some people are allergic to Nickel https://www.amazon.com/

Zac, how about the following: 1. Thermal profile for the flux 2. Is your wave leveled? - If you see better joints on one side, you should probably level the machine 3. Just for elimination, do you have another flux, that you could spray on a board

OK thanks. I had assumed that since the soldering was generally smooth and we were having no issues with bridges that the flux would be operating fine. But there really isn't much left to check so I'll get my profiler fixed (the thermocouple has been

Sergey, it will be probably hard for the money, but running/trying to run 2005 machines is not going to be fun. Probably is better to outsource your products for now and wait until you can prepare better budget for it or you find better machines for

Sergey, we understand your dilemma very good. Still the key words in your post are "having a capable system" and this is not given with that old machine. You should probably research the Samsung Tsvetan is talking about - it has 4+1 placement heads
