Abstract

A method and an arrangement for measuring the cooling rate and temperature differential between the top and bottom surfaces of a printed circuit board. The method is intended to facilitate control over the temperature differential which is encountered between the top and bottom of the printed circuit board so as to prevent warpage thereof during the formation of solder joints in a reflow solder oven.
