We have recently bought two new Pillarhose Jade selective soldering units. We are having a extremley hard time keeping the nozzels wetted while running the machine. I know that the nozzels are 99 percent iron. Has anybody ran into this problem, if so what have you done to keep the nozzles flowing correctly. We have thrown the idea of having them plated like soldering irons have done. Any help would be greatly appreciated.

Iron huh? You sure about that? We have the ERSA Versaflows and our nozzles are made out of ST37 Tool Steel. There is an "American equivalent" to this grade but I forgot what it is. You'll have to google it like I did.

Anywho, Tin or Tin-Lead solder wets great to ST37, and the solder trickles nicely out of there when it's tinned properly. Just heat the nozzle up, flux it with some strong flux (not no clean), and dip it in your solder bath for 10-20 seconds.

Samir,

You said, "You can't talk to molten solder." I curse at the molten solder from time especially lead-free. I wonder if Wave Master Larry is talking to solder with any level of success.

Cheers

"and dip it in your solder bath for 10-20 seconds."

Do you pre-tin them first or just dip them in regular solder?

Chunks, We have custom nozzles here in Riyadh that are designed to solder through-hole with SMT 0805 R's and C's just 0.5mm away. ERSA charged an arm and a leg for these, so I buy them from my toolmaker, Asadulah , for half the price. They come in "raw" & untinned, but I found that either pure tin or tin-lead works just fine for "tinning" them.

LOL - 'Surfactant will listen'. that is funny.

I too use to run Ersa machines. The new engineer has gotten me kicked off them because I know more than he do. we operators are on the machines all day, so we know more than than the engineers. They may be good on the computers, but we now the machines like our childrens navels. I found that by bendding the nozzles just right, I could sodder better than any engineer. I could get 20 more boards out a day by decreasing the dwell time from 2.5 seconds a pin to o.5 seconds! The engineers here are devils that make life harder for us.

"Bending nozzles" "Changing dwell times" "Navels" (!!!!!!!!!??????????) And probably not taking responsibility when the poop hits the fan cause "you're just an operator". Not knowing your boards, but estimating your time scenario, I'd say you're soldering some rather large boards. Removing dwell time is probably costing you reliability. 20 more defective boards a day doesn't sound cost effective to me; thus you being removed. Bending nozzles? Why not change the X/Y coordinates?

I am good with computers, but still have a tuff time covering my horns with my hair.

A pattern is emerging...

MoonMan stops posting & WML appears.... WML stops posting & the good Dr. appears....

Using the scientific methodologies instilled into me over the years by the great DaveF, I am led to the the following possible conclusions:

a) There is actually a nominated position of village idiot on SMTnet (funded by advertising revenue?) b) The postman knocked more than twice.... c) They are one and the same d) Bad things come in three's so we are set for a new, golden age of electronics manufacturing.

A little birdy told me that WML has just been on an extended vacation and will be back in the very near future. I'm sure he and the good Dr. could have some interesting and enlightening discussions. I am looking forward to it actually.

Yes the nozzels that we use are 99.8 percent iron. Does steel wet better, or do you just know that your works good.
