摘要:
A method for joining primary and secondary members comprises providing a primary member, a secondary member and a heating element which is joined to one of the primary and secondary members, wherein the heating element includes an electrically insulating matrix material and an electrically conductive reinforcing element extending through the matrix material. The method further comprises bringing the other of the primary and secondary members and the heating element into engagement and controlling a flow of electrical current in the reinforcing element so as to resistively heat and fuse at least some of the matrix material of the heating element with a matrix material of the other of the primary and secondary members. The method may be used to join a primary member such as a composite tubular and a secondary member such as a component for terminating the composite tubular.

Substrate temperature control apparatus and electronic device manufacturing systems provide pixelated light-based heating to a substrate in a process chamber. A substrate holder in the process chamber may include a baseplate. The baseplate has a top surface that may have a plurality of cavities and a plurality of grooves connected to the cavities. Optical fibers may be received in the grooves such that each cavity has a respective optical fiber terminating therein to transfer light thereto. Some or all of the cavities may have an epoxy optical diffuser disposed therein to diffuse light provided by the optical fiber. A ceramic plate upon which a substrate may be placed may be bonded to the baseplate. A thermal spreader plate may be provided between the baseplate and the ceramic plate. Methods of controlling temperature across a substrate holder in an electronic device manufacturing system are also provided, as are other aspects.

A heater comprises a plurality of zones with at least two zones having a variable power density gradient different from one another. The heater having zones of different variable power density gradients allows for controlling the heat output and temperature profile of the heater in one or more directions of the heater. The heater can be used, for example, to control the temperature profile in a vertical direction.

The invention concerns a heating element (1) for generating heat when connected to an electrical power source, comprising a substrate supporting first and second feedline (2, 2a) extending generally along opposite sides of the element (1), each feedline comprising an electrical contact point to the source, each feedline (2, 2a) distributing the power supply along it, an intermediate substrate part (3) sandwiched between the two feedlines (2, 2a) supporting a layer of resistive material, a current flowing from one feedline (2) to the other feedline (2a) in operation through the layer and dissipating heat. The layer is in the form of a pattern applied on the substrate part (3) and configured so that the sheet resistance thus locally obtained varies continuously over the intermediate substrate part (3) in correspondence to a respective predetermined sheet resistance in order to achieve a desired temperature distribution over the heating element (1).
