Abstract

The invention discloses a reliability test system and a printed circuit board assembly thereof. The printed circuit board assembly comprises a substrate, a base and fastening structures, the substrateis provided with slot connectors, two ends of the slot connectors are lug buckles, the substrate is provided with installing holes corresponding to the lug buckles, the base is arranged at one side,opposite to the slot connectors, of the substrate, and the fastening structures penetrate through the installing holes to fixedly connect the lug buckles of the slot connectors and the base. The otherside of the substrate, opposite to the slot connectors, is provided with the base, and the slot connectors and the base are fixedly connected through the fastening structures so that a plugging forceapplied to the slot connectors during frequent plugging of a to-be-detected circuit board can be transmitted to the base through the fastening structures, the base is regarded as the stress carrier of the plugging force, the damage to the substrate is avoided, and the service lifetime of the substrate is prolonged.

Description

technical field [0001] The invention relates to the reliability test field of medical equipment circuit boards, in particular to a reliability test system and a printed circuit board assembly used for the reliability test of medical equipment circuit boards. Background technique [0002] The demand for medical electronic equipment in China is increasing rapidly with the acceleration of population aging and people's increasing health awareness. Driven by national policies, medical information and technological revolution, the supply of China's medical electronic equipment market continues to maintain a rapid pace Growth, but the subsequent safety and reliability testing of medical electronic equipment is also becoming more and more important. [0003] At present, the board-level reliability test of the printed circuit board of medical equipment is to test the soldered product circuit board. During the test, the electrical stress and temperature stress are applied to the teste...
