Our PCBs manufactured with no clean flux have a waxy film on the board...is this normal? Our contract manufacturer recently switched to no clean from water wash. Thanks Carl

It primarily has to do with your product. Water wash does produce a much cleaner board from an ionic standpoint. I know products that are sensitive to ion leaking need to be cleaned. So you may want to use the customers own product as a point in s

Dave, I hear ya on the WS perks. The one thing that got me thinkin' is the BGAs. I've been doing the normal higher stuff with no issues, but sales is starting to get orders for them little buggers. I'm thinking under .8mm, I'm gonna have to think abo

I actually built a dual tank fluxer for my Econo-Pak once to handle the same thing. Not all that difficult if you're mechanically inclined. BUT, for your application I'd recommend just hand spraying the 1 to 4 boards a month with any flux they reco

Now that�s a switch. Most are moving or properly have moved in the polar opposite direction. Dano, has someone been drilling your teeth lately? We use water washable flux to: * Remove solder balls. [Or put another way, we don�t have to screw-down

Is anybody doing BGA soldering water clean solder. If yes how you are ensure cleaness. We have boards with Four BGA and 2000 chip and ICs.We are processing with no clean solder but we are getting bad wetting so now we are planning to switch to water

Grant, No-Clean paste + IPA = White Residue! #1: Stop using IPA #2: Switch to either a solvent-based de-fluxing chemical or an aqueous-based de-fluxing chemical. If you are using an ultrasonic cleaner for your boards as stated, do not use sapon

Do anyone have any experience on assembling high frequency product, 1.8GHz or 2.4GHz. In our production line, we manufacture 1.8GHz product with using no clean paste (RMA type) for reflow and no clean wire for rework. In our functinal test,either a
