When it comes to how much epoxy [aka. "glue"] to dispense to hold a IC or any part with significant mass, on the bottom of a board for wave soldering, is more better? The way I see it, one good dot should be holding such a part on the PCB. If not, th

Good ol' Yankee engineering always says "More is better" You have got to be careful that with more epoxy volume you run the risk of the epoxy merging with solder paste if you are using a glue and paste process. In addition, if the epoxy can spread o

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 -

Were not placing 0402s nor do we have a Sapphire. We are placing 0603's with both the Topaz and Emerald though without any problems. I would like to ask you if you are using any programming software for CAD conversions such as PPS or Unicam and your

Does anyone have any sort of Chart comparisons for the advantages of SMT over Through Hole? I realize this is old material and for that reason I believe it's now hard to come by (in presentation format). I know someone trying to convince a mature ent
