uuumm, we have four lines in this particular part of the factory all used for curing glue only. our other reflow lines are in another section of the factory with seperate ducts. These lines are however next door to the solder baths.....I will have to

I agree with analysis. You'll never accurately find the source until you determine exactly what the "goo" is. We have this problem, but like previous posters, the goo is flux residue. We do use the ovens for both reflow and adhesive cure. The adh

We don�t use this glue. What does Heraeus say about your condensate? [I'm With the previous poster. Your condensate sounds like goop from NC flux not glue.] How to clean out a 3 meter length of chimney? Depends on your tolerance for pain * Take

Hi folks, What are the differences between Epoxy resin(ER)conformal coating and adhesive stacking/bonding material? My PSA/PRA (Post solder/reflow assembly)bracket assembly process got some ER adhesive encroachment on pads/solderjoints. I have chec

In addition to Dave�s response: RO fluxes are based on natural pine (tree) rosin. RE fluxes are based on synthetic or modified rosins called resin. Below a couple of advantages resin can have compared to rosin: � Better thermal stability. � Resin

Many thanks Saaitk, The PCB to protect could be (fuel cut off control system against tiefs ...)located in between driver cabin and engine. I have done a quick look on HumiSeal Automotive Products, found Acrylic Resin, Model 1B66 should be a suitabl

In older resin materials used in printed circuit board fabrication, there seemed to be a direct relationship between CTE and Tg. Now with more modern resins that reationship no longer appears clear. Please comment.

we recently installed an aqueous cleaner. it is consuming alot of energy and di resin beds. is it advisable disconnect the resin bed and go straight to city water? the cleaner has its own filter system.

Marc: In printed circuit board fabrication, fabricators place sheets of prepreg between each pair of glass cores. They stack these layers into books. As they heat and press the books, the sheet melts into an epoxy glue. The thickness of the prepr
