ABSTRACT:
A method for manufacturing circuit boards which control digital displays includes a TV camera which images the digital display. The output of the TV camera is fed into a computer which controls a laser trimmer. The laser trimmer trims the resistors on the controlling circuit board until the desired value and characteristics are obtained on the digital display.
