Abstract
A dielectric component with electrical connection is provided for a laminated heater mat (3) for an ice protection system for an aircraft (1). The dielectric component with electrical connection comprises at least one dielectric layer (50, 55) comprising thermoplastic material, and the dielectric layer (50) or a stack of the dielectric layers (50, 55) has first and second main surfaces and a hole (505) extending between the first and second main surfaces. A first sprayed metal coating (501) comprises a first portion (503) deposited on the first main surface (502) adjacent to the hole (505) and a second portion (5014) which projects into the hole. A second sprayed metal coating (5013, 5513) comprises a third portion deposited on the second main surface (506, 552) adjacent to the hole (505) and a fourth portion (5015) which projects into the hole (505). The second portion (5014) overlaps the fourth portion (5015) to form a continuous conductive path between the first main surface and the second main surface. This provides a cheap, neat and thin connection through the dielectric layer or the stack of dielectric layers.
