Coating for medical micro circuits can be LED-cured

A flexible coating for circuits used in small medical devices cures quickly to be tack-free for immediate handling.

The DYMAX MD 1901-M flexible, LED-curable coating for medical micro circuits in hearing aids, wound-care devices and medical pumps, has the ability to be tack-free immediately after curing. According to Intertronics this helps prevent defects that could occur as a result of components being handled too soon.

Compatible sterilisation methods include gamma irradiation and ethylene oxide, as well as auto-claving. These are dependent upon application. Typical applications include coating of medical micro circuits, sealing and moisture barriers encompassing substrates such as glass, FR-4, metal, ceramic, glass filled epoxy, CAP, PS, TPU and aluminium.

The coating is ISO-10993-5 cytotoxicity-approved as a medical grade electronics coating, seal, or moisture barrier. It is low-durometer and flexible and therefore able to be used on flex-circuits as it resists cracking or delamination while the board is being flexed. The coating’s secondary heat-cure capability ensures a complete cure for areas that may be shadowed from the light source.

The coating complies to the RoHS Directives 2002/95/ECX and 2003/11/EC
