Abstract
In a method of manufacturing an electrothermal heater mat, a heater element is deposited on a first one of the dielectric layers of the heater mat by using a laser blown powder process.
Claims11
A method of manufacturing an electrothermal heater mat, comprising:
- providing a first dielectric layer;
- depositing a heater element on the first dielectric layer by using a laser blown powder process, wherein the heater element has a first length of a first thickness and second length of a second thickness, and during depositing the heater element, a deposition tool is arranged to deposit a greater thickness of powder at the first length than at the second length;
- forming a stack comprising the first dielectric layer, the heater element, and one or more further dielectric layers;
- and
- laminating the first dielectric layer together with the one or more further dielectric layers of the stack.
