ABSTRACT:
Electronic components are provided for connection in electronic circuits being manufactured on a production line. A supply of component blanks is provided, and each of the electronic components is formed by removing material from one of the blanks. The electronic component is delivered for connection in a corresponding one of the electronic circuits. The steps of forming and delivering the electronic component are coordinated with the manufacture of the corresponding electronic circuit. Another aspect features high-volume, high-mix manufacture of electronic circuits on a production line, where the mix requires a number M of different component values within a range of values R, and N (smaller than M) different supplies of component blanks are provided, each supply suitable for making components having values within a subrange S of range R. In another aspect, operating parameters of a laser are determined automatically for use in trimming resistor blanks belonging to a common batch of blanks. In another aspect, each circuit includes an alterable component having a parameter value which can be altered and the alterable component is open-loop trimmed.
