Package and Board Level Shielding
MG Chemicals offers conductive paints for package and board level EMI shielding applications. These coatings are designed to prevent components on a board from interfering with each other with EMI. They can save space and cost by replacing larger metal stamps and lids.
We offer a 1-part acrylic version that is suitable for post-soldering shielding of components. We also offer more durable urethane and epoxy versions suitable for use on silicon wafers and package level applications, which are wave solder resistant and do not fray when cut.
For device level shielding we offer acrylic conductive coatings, and for wood or drywall we offer water-based alternatives. We also offer silver conductive adhesives that can be useful in package applications.
