post the website or search term you used to find this SPI/ AOI machine. I've never heard of such a thing. Is is pre-reflow AOI or post-reflow?

1. The jetting head flies very low to the level of the board. So, performing AOI function will crash the head. 2. AOI is performed close to the end of the line, after P&P or reflow. Are you planning to run the boards back-and-forth, on the line? 3. L

Try to process the composite pallet through the wave without any flux and view volume of smoke and if any residue is deposited in the wave when it exits. My guess is that the pallets are releasing some binders that are high boiling and this in turn c

hello Zac, if you are running pump at 100% and there is not enough wave then you will probably need to empty solder bath and clean everything. also check pump parts for tear and wear. eached solder inlet can make a lot of problems when it comes to w

I have checked pot temperature in different parts of solder pot and it looks like it is correct (250C). I have also lowered solder pot temperature and removed copper from the surface of the solder pot (operation repeated couple times). There is still

There is one lead that is a total miss. I think you are too low with the wave there - you are barely touching the board. I would say first look at your wave height. If you have the possibility to change the angle of the wave(if there is a backplane t

Thanks Bukas. I've actually gone to a lot of trouble over the past 24 months to completely clean, rebuild and adjust the pump and nozzle assemblies and even through all of that we've still never been able to get theoretical maximal wave height from t

I was wondering if anyone has studied the effects of tin lead solder in the wave. If we leave the same solder in the solder pot, how many COMPLETE cool downs and start ups can the solder go through before it begins to break down? Please let me know

are you using composite pallets in the wave or oil/wax around the pump impellar? cheers greg

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
