Claim 13:
14. A test method for an unpopulated printed circuit board comprising the steps of:
arranging an unpopulated printed circuit board between a first heating plate and a second heating plate;
a) generating heat by activating the first heating plate and the second heating plate and exposing the unpopulated printed circuit board to a temperature encompassed by a reflow soldering process in the range of 200° C. to 250° C.; and
b) while the unpopulated printed circuit board is exposed to a temperature in the range of 100° C. to 120° C.:
measuring resistance and/or capacitance of one or more electrical connections of the unpopulated printed circuit board and comparing the measured resistance and/or capacitance to a reference value; and
determining whether the electrical connection of a network test point is electrically connected to another electrical connection of the network test point based on the comparison.
