Abstract

The invention provides a preparation method of a high-reliability printed circuit board of photovoltaic inverters, and specifically relates to a preparation method of multi-layer board. After the L1 to L7 layers and the L8 to L14 layers are respectively processed and prepared, the L1 to L14 layers are laminated. In the process, a different hole copper manufacturing process, a high multi-layer lamination manufacturing process and a depth control drilling depth control process are further designed for processing control and manufacturing. The problem of various defects in the production of existing multi-layer laminated circuit boards is solved, the production cost of the circuit board is greatly reduced, and the quality and production efficiency of the high-thickness multilayer circuit board are improved.

Description

technical field [0001] The invention relates to a manufacturing process of a copper plate, in particular to a method for preparing a printed circuit board of a high-reliability photovoltaic inverter. Background technique [0002] Photovoltaic inverter is a power adjustment device composed of semiconductor devices. It is mainly used to convert DC power into AC power. It is generally composed of a boost circuit and an inverter bridge circuit. The boost circuit boosts the DC voltage of the solar battery to the DC voltage required for inverter output control; the inverter bridge circuit converts the boosted DC voltage into an AC voltage of common frequency equivalently. [0003] Photovoltaic inverter printed circuit board (Printed Circuit Board, PCB) is an important part of the photovoltaic inverter, which undertakes the important function of current transmission. During long-term use, its heat generation is very large. , the signal control is precise, and the surface copper an...
