ELECTRONIC COMPONENT HAVING FUNCTION TO DETECT MANUFACTURING DEFECTS OR DAMAGE/DEGRADATION AND PRINTED WIRING BOARD

摘要

An electronic component having a plurality of terminals arranged on a bottom side of a package and mounted on a printed wiring board includes at least one detection terminal as a portion of the plurality of terminals, the detection terminal being connected to a ground outside the electronic component, wherein the detection terminal is connected to an input port of an input buffer and one end of a resistor inside the electronic component, the other end of the resistor is connected to a power supply, and the input buffer detects a poor connection of a solder joint or a socket by outputting a first binary signal obtained by binarizing a voltage level input into the input buffer using a predetermined threshold.
