I would suggest you call Dymax (may be Diemax) - they are the adhesive experts when it comes to UV curing materials. I am very sorry, but somehow they are not in my database. You should be able to find them on the net under and adhesives+UV search.

As a basic guide the minimum spec you should look for is 500g you should achieve a force on most chip parts of 800-1000g. Parts are lost on wave soldering due to no material, poor curing, poor surface adhesion and poor handling. Its not the wave sold

Having worked with adhesives for years, the first thing to look at if there is a failure of this type is surface contamination. The subject has been discussed here also. A structural adhesive will increase in strength with a "hotter" cure. We also

Hi I don't know of anything special in the ways of dispensing since they don't normally care about the differences of UV or Conductive or pastiness. The only difference is WHAT you are striving to do with the adhesive and how the adhesive moves as

We had a great deal of trouble cleaning adhesive residue from stencils using an alcohol stencil washer. Same kind of thing, adhesive build-up in aperture corners. The solution we came up with was to convert our stencil washer to run Zestron ES200, a

We have a line using the DEK Pump Print process. We use a 3mm plastic stencil and print adhesive through it. The adhesive we use is Heraeus 955. We've struggled with adhesive contaminating the pads of our smaller components. The deposit isn't on
