A film coater just introduced can provide automated, selective and precision application of conformal coating materials.

The coater from Nordson Asymtek, Carlsbad, Calif., provides greater than 99 percent fluid transfer efficiency, improving material utilization by 30 to 50 percent, according to the company.

The Select Coat SC-280 coats complex circuit boards in seconds, says its maker. Because the coating material is not atomized and is applied precisely to the selected areas, overspray, masking and rework associated with more conventional conformal coating processes are minimized or eliminated.
