The ward call system consists of the call host installed in the ward nurse station and the call extensions set on the bedside of the ward, the ward of the ward, and the corridor display. Once the ward bed or bathroom is pressed by the call button, the host of the nurse station will make a sound. The light alarm signal, at the same time, the corridor display screen synchronously displays the call bed number, and the nurses can immediately rush to the ward to handle the emergency. It is important that the call extension in the bathroom needs to be waterproof. In addition, in order to facilitate the work of the ward staff, the therapist can install the call and display device so that the therapist can know the situation in time. Different from traditional FR-4 (plastic), ceramic materials have good high-frequency performance and electrical properties, and have properties that organic substrates do not have, such as high thermal conductivity, excellent chemical stability and thermal stability. Ideal packaging material for large scale integrated circuits and power electronic modules.
