Stephen, you better believe the nurse she's right If it would be possible to produce lead vapors you would see lead vapor condensation in the hood or in the ducts. Never seen any lead deposits anywhere. There is no reason for concern The absence of

Had a Treiber in a past live. Had a standard air knife in the first section and then a turbine blower with a stainless steel air knife with about 15-horse motor. Had some problems with bearing on the turbine Make sure the exhaust hot air doesn't con

You should also check the quality of your compressed air. If the proper filters and desiccants are not in place, you could be recontaminating your washed boards with condensed water and oil residues from the compressed air used for drying. Bill Sch

Armando: We're guessing that the white residue is on the laminate also. We believe that the residue has something to do with your low residue flux and water. It could be: * Water contamination in the flux. * Poor selection of preheat temperature that

Wanted to ask the SMT community if anyone has data on baking Clariant Desi Pak for 16 hours at 245 F. How are you cooling to avoid condensation reforming? Have you measured efficacy of desiccant after baked 10 times? 100 times 1000 times? 5000 t

Steve, If you can get me your snail-mail address, I will send you some latest information. We actually have a totally new system called Delta 5. It is Condensation Soldering rather than Vapour phase, the difference being that we solder in an air ti

I am currently running several SMT lines that are placing components onto dispensed adhesive (Heraeus PD 944). My problem is that we have always had an issue with a resin type liquid �condensing� on the inside of our oven chimney and then running bac

Paramjeet Singh Gill Flip chip with aqueous flux, that's interesting. * What is the stand-off from the board is your flip chip? * What machinery and materials do you use clean your boards? * How do determine the cleanliness of the board under the fl

What you can do is perforate the board holding rim by drilling holes of 0.6mm (similar to via's). This will reduce the mass and heatsinking capacity, allow excess flux drainage and facilitate convection heat contacting the board through the holes. Th

Is the oven air or nitrogen? If it is air I would suggest more exhuast to pull the flux vapors out if the oven before they can condense in the cooling. If it is a nitrogn machine that makes it a little more complicated. If the filter system is clogge
