Thx to everyone who replied. we will be running single sided thru hole and double sided smt, 186 rosin flux cause they tell me it can take the heat needed for 18 layer pwbs. some long leads. also they are ordering in pallets to deal with the irregu

Hi all, I have a question regarding some wave pallets having metallic traces of Titanium. The solder mask is blistering in some locations on the PCB and I am wondering if this Titaniumn may have an influence by incresing locally the temp. Also we ar

I am using a Novastar 12S solder wave with Kester water soluable fux 22-2425. I have used this for years without problems on an old Hollis machine. Just started using the Novastar and after fine tuning I get itermitten bridging on the front of the P

Kester has a special alloy for high temp soldering. Alloy 123. I would think that if you coocked 63/37 to 360c you would have a pot of dross in no time! Doug

We are running an RMA flux (Kester 1515). Changing the angle didn't help any so we're back at 6 degrees and placing an order for the lambda nozzle changeover. Are you currently running the debridging knife?

Hi I have been struggling with boards for high quality picky customer. I am getting flux waves (like splashed - too hard to clean) after wave, where as we are still using Kester 979 (No clean flux, but as we are getting visible marks which looks si

We have had some discussions about what causes parts to lift out of the holes when going over the wave on our flow solder machine. The machine being used is a Treiber (700 series). There are two bottom pre-heaters and one top pre-heater. We try to pr

| I am running a board that is .062" thick and has components that over hang the edge of the board by .090". I have bottom side smt components (chip caps and resistors only) and use the turbulent wave to help solder the components. The problem I am

Try spraying flux on top of the loaded PWB when you put it on the conveyor. The tackiness of the flux does a pretty fair job of keeping the axial leaded parts down to the board. This takes more cleaning, but it has worked wonders for me on assemblies

We are using the Kester 979 with excellent results; the bonus is that it can be cleaned w/Di water.
