We have been using a VOC-free, no-clean flux on our boards that we conformally coat with no problems. We're using both a UV cured and a heat cured Silicone conformal coating. One thing to beware of is inhibition in the silicone. We found that out t

Hi there, I intend to mount some smt components on the soldering side of the PCB and solder via wave soldering equipment. We do not have a reflow oven to cure the glue. Does anybody have a suggestion what small heat cure equipment or system can be u

Does the manufacturer of your glue suggest a curing temp? If so and if ya dare..seems to me you do, you could use an oven something like a bakers oven. We use HI Temp ovens to cure epox, glue and stuff like that. Sounds to me like it's time for a new

I'M LOOKING FOR A SOLVENT TO MAKE REMOVING EPOXY FROM THE BOTTOMSIDE OF BOARD ON SMT COMPONENTS. THIS IS MOST IMPORTANT AFTER THE EPOXY HAS CURED AND EVEN RAN THROUGH THE WAVE. I'M LOOKING FOR A WAY OF MAKING THE REWORK PROCESS ON THE CURED EPOXY MO

We are experiencing many solder balls after wavesolder. Two different board suppliers of the same board are involved. My initial reaction was that it was the process but in researching information in this forum I am beginning to wonder. How can on

One of the safest ways to dispose of urethane conformal coating waste is to cure it. Once it's cured it no longer is considered a hazardous waste. In the uncured state it is. We have tubes of epoxy adhesives (out of shelf life) that we do the same

I currently use Chemask CM8 Peelable Masking which currently takes 30 - 60 minutes to cure. Does anyone know of another solder masking which cures in less time at room temperature. I know that curing times decrease using an oven, but that is not an

Wait...stop! Some adhesives will void when cured... some common branks... maybe already mentioned. Heraeus PD955 will minimize voiding when curing the adhesive. Voiding can have devestating consequences....learned from experience. Another key is kee
