Temperature sensing plate of laminating machine

Abstract

The invention discloses a temperature sensing plate of a laminating machine. The temperature sensing plate of the laminating machine is formed by a heat transfer plate body provided with a plurality of temperature sensing wires in a buried mode. When the laminating machine is used for lamination, the laminating machine does not need to be stopped, the temperature sensing plate is only needed to be placed in an intermediate layer of material layers to be laminated in a parallel and overlaid mode, so that procedures and time for forming grooves in the plate and connecting the temperature sensing wires are eliminated; and after the lamination, the temperature sensing plate can be drawn out for being reused for the next time, and therefore the temperature sensing plate of the laminating machine can save working procedures and working hours of a laminating process.

Description

technical field [0001] The invention relates to a temperature-sensing device for testing the internal pressing temperature and temperature uniformity when a printed circuit board undergoes a pressing process. Background technique [0002] In the process of multilayer printed circuit board (PCB) processing, it is essential to use a lamination machine, and the lamination temperature of the lamination machine and the uniformity of temperature have a great influence on the quality of lamination, so sensing and Controlling the pressing temperature is an important measure to ensure the quality of product pressing. In the pressing process, the pressing machine generally uses a thermocouple thermometer, and makes a few more temperature-sensing lines (thermocouple wires). Place a temperature-sensing line), when placing, it is necessary to open a groove on the circuit board, place the temperature-sensing line in the groove, and record the temperature data of each position after press...

Problems solved by technology

In the pressing process, the pressing machine generally uses a thermocouple thermometer, and makes a few more temperature-sensing lines (thermocouple wires). Place a temperature-sensing line), when placing, it is necessary to open a groove on the circuit board, place the temperature-sensing line in the groove, and record the temperature data of each position after pressurization. It is necessary to stop the machine before connecting the temperature sensing line, and it needs to make a slot on the board, which takes about ten minutes, so it is time-consuming and labor-intensive.
