Abstract:
A method for fabricating an electronics board with thermal-conduction cooling, the board having at least one surface having a printed circuit including associated electronic components fixed to the printed circuit, the method comprising:scanning the at least one surface including the printed circuit with the fixed electronic components with a sensor to obtain profile information and related coordinates of various points on the at least one surface having the printed circuit including associated electronic components;delivering the profile information and related coordinates to a computer system;processing the profile information and related coordinates using an image program with a subroutine for smoothing the profile information and related coordinates so as to obtain smooth reliefs as a part of a machining program;controlling a programmable machine tool using the machining program to machine a rigid heat sink so that a machined face of the rigid heat sink closely matches the profile of the at least one surface having the printed circuit with the fixed electronic components; andcovering and mechanically fixing the machined rigid heat sink to the at least one surface having the printed circuit with the fixed electronic components.
