As has already been mentioned, black residue is usually either from dross or just a dirty pot, pump, baffles, etc.. I also saw that maaaany years ago in a system that used a flawed oil intermix "feature" but hopefully those systems are long gone.

No matter what type container you use, air in the delivery line will always be a problem. When you pop the lid on a pressurized container, fill it with a liquid and reseal it, air will be present over the liquid. Where do you think it goes?It has to

Masdi, Try board shunts. They are hi-temp rubber strips with grooves cut. They can be popped on and off with ease and are much faster than taping and considerably cheaper. They also work great for masking goldfingers prior to wave soldering. Contac

I recently wrote a program on one of our Pilarhouse Jade machines and receiving an error. The machine has the feature of "Wave Height" that I don't have enabled for a 2.5mm extended tip nozzle. This is the only program that I haven't used this featur

As I mentioned in another thread, I've always been one to flux the living crap out of a board until the ICT guys start yelling at me, which actually did happen last week. I had a little oriental guy (an immigrant to Riyadh from Vietnam), clicking an

I ran some test samples with a water soluble past (Amatech ws488). I also tried hand soldering using an Alpha ws375 wave soldering flux and some old fashioned RMA. The results are pretty much the same. Some of the joints look a better that others b

Hi Thomas Ever considered that this maybe HASL flux left on PCB as this is extremely hygroscopic and has heat transfer fluids that cannot be baked out unless you go to a temperature of around 600C. One way of testing is to leave iron tip on joint an

Thats the problem residual residue from HASL fluxes Lead free especially are worse.Very hygroscopic and out gass and produce dewetting as well over wave soldered boards especially. Leave iron on blown joint and will after several seconds fizz and pop
