Hello Chris, If you could humor me, what are the limiting factors forcing your dot size to .010"? What is the die size that you are placing? What are the accuracy tolerances? Was eutectic die attach never an option for this bare die? Have you de

Screen printing glue is definitely easier and more repeatable than using dispense methods (my opinion). Depends a lot though on pcb design and component mix. Contact your stencil vendor and they will be able to suggest different apertures, such as li

We had a Quad 4C that was fitted with a dispensing nozzle. It was perfect for jobs like this. Place the 1st component in the paste, add a dot or 2 of paste to the top of that part and then place the 2nd component on top. I beleive that you may be ta

Hello SMTA, I am looking into the possibility of automating, or semi-automating the application of thermal gel (THERMA-A-GAP GEL8010) onto the bottom of some power supplies installed in PCBs. As of now I will need to apply approx. 5 mils of this gel

| OK, my manager read an article on printing glue (aaargghh!)and wants to know why we aren't doing it. We currently use Fuji GLs and GDMs to dispense glue. I've never done it, but have seen it done at NEPCON and other shows. It looks OK, BUT what
