Form-In-Place EMI Gaskets
Series No. 8000
MAJR Products’ Form-In-Place (FIP) EMI gaskets are offered to facilitate the increasing demand for EMI shielding of smaller profile and mechanically tight tolerance areas for a variety of metal and plastic housings. Our software-driven, automated Form-In-Place EMI gasket dispensing system delivers a custom-programmed, precise bead of conductive elastomer to narrow flanges or edges as small as 0.030 inches (0.762 mm).
The conductive elastomer bead is ideally placed on commercial or military compartmentalized enclosures, cellular handsets, pc cards, or a variety of other mechanically tight products. Quick prototyping and short to medium production runs are our specialty.
Overview
Form-In-Place EMI Gasketing (8000 series) MAJR Products Form-in-Place automated EMI/RFI gasketing is offered to facilitate the increasing demand for shielding of smaller profile and mechanically tight tolerance areas for a variety of metal and plastic housings. Our software driven automated gasket dispensing system delivers a custom programmed precise bead of conductive silicone, also known as conductive elastomer to narrow flanges or edges as small as 0.030 in (0.762 mm).

Technical Information
The robotic bead location holds a pattern positional accuracy to 0.003 in. (0.076 mm) in the X, Y, and Z axis dimensions, and the repeatability of each axis is 0.001 inches (0.025mm). The heated vacuum tooling plate bead dispense area for the X and Y axis is 17 inches by 14 inches. The Z axis dispense area has a range of 3.5 inches. If a bead needs to be dispensed on a part that is over the travel dispense area of the machine, part rotation and dispensing of a second bead path after the first bead path can be performed to complete the gasket.
The conductive particle-filled materials are one-part electrically conductive room temperature curing elastomers. The extruded paste material cures rapidly when exposed to atmospheric moisture. When completely cured, the materials are highly resilient elastomers that exhibit superior adhesion to a variety of substrates and exhibit low volume resistivity.
