Embodiment Construction
[0034] The present invention will be further described below in conjunction with the accompanying drawings.
[0035] The solid high solid low fault injection circuit for online testing of digital circuit boards of the present invention includes variable resistors R1, R2, cable assembly M, lead wire set L, switch K, selection switch K1 and external probe T integrated on the circuit board , T1, T2, such as figure 1 shown.
[0036]Among them, the cable assembly M is composed of n cables, n≥1; one end of each cable can be connected to a probe T through a conductive flexible wire, and the probe T is used to connect with the input signal pin in the digital circuit board chip; each The other end of the cable is connected to the lead group L through a switch K, and the switch K is used to control the on-off connection of the probe T connected to the cable, thus passing one or more probes T and one or more digital circuit board chips. The input signal pins are connected to realize si...
