Hey Graham,

We recently switched from a Gardiner formula RMA flux to Kester 186 and
186-18.

The chemistry we use in our PVC plumbed Tooltronics Ultra Clean II is Kyzen
XJN.  My Division also has a couple of stainless steel Westek cleaners as
well.  XJN has worked fine for typical boards but not all our stuff is
typical.  I'm still working on a presoak to loosen up the tougher areas.
One concern I have is using a piece of equipment from a company which no
longer exists.  There's no handy 800 number to call when I'm 'discovering'
something new.  I'd stay away from Armakleen, our experience - it scales up
way too much and doesn't last very long, but I've never personally used it.

I would highly recommend holding out/begging for a machine with stainless
steel pipes.  We have a 'plan' to retool the Tooltronics with stainless
steel for around $20k or so.

The latest is coming up with enough baskets for lighter/smaller boards which
float above the conveyor belt.

Later,

Hans
