Abstract

The present invention discloses a film thermocouple temperature sensor inlaid into a multi-layer PCBs, and a transient temperature monitoring system and method. The system comprises: a film thermocouple temperature sensor located between any two PCB requiring monitoring transient temperatures, wherein the film thermocouple temperature sensor is formed by laminating each prepreg and multiple PCBs into one body through adoption of a PCB lamination process and parameters; the plurality of prepreg; the PCBs with different layers; a cold-end compensator connected with the film thermocouple temperature sensor; a signal amplification module connected with the cold-end compensator; a data collection module connected with the signal amplification module; a computer; and upper computer software. Thefilm thermocouple temperature sensor inlaid into the multi-layer PCBs, and the transient temperature monitoring system and method achieve real-time and accurate measurement of temperatures between the PCB layers, and are rapid in response, accurate and convenient to locate and high in measurement precision.

Description

technical field [0001] The invention belongs to the technical field of sensors, and in particular relates to a thin-film thermocouple temperature sensor embedded in a multilayer PCB board, a transient temperature monitoring system and a method, which are suitable for high-precision monitoring of the temperature during operation and processing of a multilayer PCB board. measurement field. Background technique [0002] With the rapid development of industries such as computers, mobile devices, and communication facilities, related electronic products are developing in the direction of intelligence, high density, integration, and miniaturization. Printed circuit boards (PCBs) are used as the connection and support of electronic components body, which plays the role of relay transmission in electronic products, and high-density integrated electronic products put forward higher requirements for the quality of PCB boards. Among them, the interlayer temperature of the PCB board is...
