Abstract

The invention provides a monitoring system of a tunnel oven. The monitoring system of the tunnel oven comprises a multi-temperature-section tunnel oven, a plurality of temperature controllers, a control module and a monitoring device, wherein the multi-temperature-section tunnel oven comprises a plurality of baking areas; the plurality of temperature controllers are respectively correspondingly arranged in the plurality of baking areas and are connected to the control module through a control bus to detect the actual state parameters of the corresponding baking area; the actual state parameters are reported to the control module through the control bus; the control module is connected to the monitoring device and used for acquiring the actual state parameters reported by the plurality of temperature controllers, of the plurality of baking areas, and outputting the actual state parameters to the monitoring device for storing data. With the adoption of the monitoring system of the tunnel oven, the data traceability of the tunnel oven can be realized; in addition, the operation flexibility is improved.

Description

technical field [0001] The present invention relates to a printed circuit board (Printed Circuit Board, PCB) manufacturing technology, in particular, relates to a tunnel oven monitoring system applicable to a PCB baking board process. Background technique [0002] Printed circuit boards are widely used in electronic products to carry functional circuits inside electronic products and to realize electrical connections between different functional circuits. In the production process of the printed circuit board, the baking plate is an important process, which mainly generates high temperature through the oven to completely cure the semi-solid ink on the surface of the printed circuit board within a certain period of time. Traditional circuit board ovens generally can only display real-time baking temperature and other parameter information on the control panel for technicians to monitor the working status of the oven. However, the above parameter information is usually not tr...
