摘要:
The present invention relates to a method for detecting failures of electronic units (3) in a printed circuit board assembly (1), comprising the following steps of: consecutively activating the electronic units (3) according to a power-up sequence,wherein in each activating step one or more of the electronic units (3) are activated; after each step of activating one or more of the electronic units (3), obtaining an indication of an electrical parameter change with respect to a state before activating the one or more electronic units (3) and comparing the indication of the electrical parameter change with a provided reference parameter change associated to the one or more electrical units (3); and signaling a failure depending on the result of each comparing step.
摘要(中):
本发明涉及一种用于检测印刷电路板组件(1)中的电子单元(3)的故障的方法,包括以下步骤:根据上电顺序连续激活电子单元(3),其中, 每个激活步骤中的一个或多个电子单元(3)被激活; 在激活一个或多个电子单元(3)的每个步骤之后,获得关于在激活一个或多个电子单元(3)之前的状态的电参数变化的指示,并将电参数变化的指示与 提供与所述一个或多个电气单元(3)相关联的参考参数变化; 并且根据每个比较步骤的结果发信号通知故障。
