Is more epoxy better?

It may be the case (if you are using stencils to apply the epoxy) that you will have to indeed use a stepped stencil to appply the epoxy at a greater height. Not being an engineer i am not completely clear with the involvements of stencil design -

We have been screen printing adhesive for about 4 years. Works well but it does require my opertators to pay more attention to what they are doing than they would prefer. Keep your stencils really clean. Once that epoxy dries in an aperture, it is

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

Just a note about cleaning SMD adhesives. Cleaning does not need to be hazardous. Smart Sonic has a non hazardous process that has been used for over 9 years using a non hazardous detergent that has been certified by the AQMD as a clean air chemist

In past PCB designs I have cleared all traces from all layers (except pwr/gnd) from fiducial area. It has come to my attention that this is only necessary on the side where fud is placed. Which is the correct method of design using a fidicial?

Hi, I need some urgent informations on stencil design guidelines on how to perform epoxy printing on 0603 and 0402 components. Could anyone help? ( Reflow process is not possible because of some other constriants) Sec
