How do apply it in your process? It would seem best to screen the electrically conductive epoxy then dispense the thermally conductive epoxy to bond the part to the heat sink pad. Any help or opinions would be appreciated. I dont think the System Uni

Has anyone tried to use electrically condctive adhesive rather than solder to connect the leads on 5 watt Luxeon parts? If you design the board right to dissipate heat, when you have a bunch of them in a tight array, even with thermal relief on the t

We did the trial by dispensing (both the thermal & the electrical), but in production I would definitely use a stencil for the Conductive adhesive, as the shape, spread & volume of the adhesive is critical. (No wicking or spread) We also looked at

That you have 'grainy' solder only at the ends of the connector and not at all solder connections indicates that your quality types are on track and are pointing you in a direction worthy of investigation and developing a better understanding of the

We use an LM2575 switching regulator, and have had no trouble reflow soldering it. It is made for that purpose, so no big tab with the bolt hole, and the leads are pre-bent for SMT. Note that soldering the part to the PCB doesn't really give the he
