Abstract

The invention discloses a cleaning method of a high-frequency flexible microwave printed circuit board, and the method comprises the steps: attaching a high-temperature-resistant protection film to a wiring surface of a circuit board, and enabling the wiring surface of the circuit board to be completely covered by the high-temperature-resistant protection film; performing high-temperature curing treatment on the circuit board attached with the high-temperature-resistant protective film to obtain a finished circuit board; carrying out film removing treatment on the finished circuit board so as to remove the high-temperature-resistant protective film on the finished circuit board and obtain a cleaned finished circuit board; according to the invention, the precipitated epoxy resin is isolated from the wire on the surface of the circuit board by using the high-temperature-resistant protective film, so that the purpose that the circuit board is clean and tidy after being bonded is achieved, the wire is not damaged, the cleaning quality and efficiency can be improved, and the large-batch production of the circuit board is facilitated.

Description

technical field [0001] The invention relates to the technical field of production and assembly of high-frequency flexible circuit boards, in particular to a cleaning method for high-frequency flexible microwave printed circuit boards. Background technique [0002] The high-frequency flexible microwave circuit board is the carrier of high-frequency electrical signals and microwave signals in the microwave radio frequency module assembly, and is an indispensable and important part of the microwave radio frequency module assembly. [0003] At present, the high-frequency flexible microwave circuit board in the microwave radio frequency module assembly mainly adopts the conductive adhesive bonding process (that is, the conductive adhesive is applied on the back of the circuit board to realize the electrical conduction of each connecting material in the circuit board), and the conductive adhesive belongs to the ring Oxygen resin adhesives, during the high-temperature curing proces...
