the problem I had with pump was that turbine intake was eached by alloy. when I repaired intake, it was a irregular hole about 32mm in diameter, mechanics welded piece of plate with a 24mm hole (that was a factory size) we had to reduce pump speed fr

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 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

I am dealing with a similar uncoalesced solder issue. This defect has come and gone several times during the last 6 months. See image. In my case, I am using conventional SnPb solder and an entire strip of my OSP finished board (includes various de

Hi Zac, was that board finished with tin/lead HASL or leadfree/HASL? Also what type of flux were you using? Just because a board is fresh out of sealed packaging doesn't necessarily mean that it's going to solder well. The picture that I've attached

SuMoTe, that is a fair suggestion, but I believe will be a non-starter. The solder pump motors are actually 40V motors being run from a PWM 24V supply. I did one time try hooking up to a separate power supply up to 40V but all this seemed to do was m

I agree. Trim the leads before insertion, then raise the pot height. With the information given, this is most likely your solution. Our machine has a dam wall on the rear of the solder pot that raises the height on the solder pool. I would make sure

Thanks for the suggestions. 1. By this are you referring to the flux specifications or the actual profile of the machine? 2. Yes, the entire machine, the solder pot and the wave nozzles have all been levelled. The better joints on one side are perp

May be you right, but I spend a lot of time on Technet (a similar site maintained by IPC) and people who posted questions usually come back saying whether the problem has been solved, as someone else may face a similar problem down the road. I think
