Hi. I am looking for a printer that can print a conductive circuit on a thin film, like polyester or mylar film. Any lead would be appreciated. Thanks, bme

The company that does this is McDermid. There are multiple different ways of doing it. Screen print silver paste onto the mylar, "activate" the film to be conductive, then plate in copper. These processes are found in the patent literature which is e

Thanks for sharing your experience. I have similar view too.

Hi, Pl let me know about opinion/experience whether thick film chip SMD resistor which is MSL-1 Required to bake before being usedon SMT line. I want to use SMD resistance spool which is around 2 yeasr old kept at 25 deg room temperature at around 4

Steve- We had the same trouble with 0805 Panasonic film caps. We had some tombstoning and open solder joints (non-wetting). We found two problems...like you, we changed our pad design to meet their recommendation. Also, they were able to suppl

MSL 1 is unlimited factory floor time before reflow. I have spools that are 10+ years old and haven't encountered any issues using those parts. It goes without saying those parts are not exactly used in volume so its not a massive sample but that is

On the new 4797 T12W8P feeders we are having trouble picking the very thin chip resistors. Adding foam to the feeder (beneath the pick point) helps, but it only minimizes our frustration. Universal has a reel of these parts and they are looking into

Yes to all of the above with the exception of the part sticking. The same parts are EASILY picked using the 4790/91 feeders on a 4790/91 machine. The new feeders just flip the part out when the feeder advances. Thanks! Lee

You seem to pretty far from shore to begin thinking about boats and floatation devices. Most laser trimmers are used by: * Semiconductor fabricators * Resistive component fabricators * Hybrid circuit assemblers Component fabricators and hybrid [

We have an HSP 4796, if the feeder mechanism is the same, this may help you a bit. First make sure that the componet definition is right on the component library. Tape or Embossed. Second, the component thickness vs actual thickness. Is the pick u
