Abstract

The invention discloses an integrated bypass protection device used in the field of solar energy and a process method thereof. The invention belongs to the technical field of electronic component manufacturing. The device includes multiple frames which are horizontally connected in sequence. Protection device plastic package bodies are arranged at the connection parts between the frames; the protection device plastic package bodies are integrated on the frames and form an integral structure with the frames. Photovoltaic chips are arranged in the protection device plastic package bodies. Chip bonding pads and jumper bonding pads are arranged above the frames, the photovoltaic chips, the chip bonding pads and the jumper bonding pads are arranged in the protection device plastic package bodies, the photovoltaic chips are connected with the jumper bonding pads through jumpers, an anode pin and a cathode pin are connected to the exterior of the frames, and the frames bear and communicate the photovoltaic chips with an internal circuit and an external circuit to form an integrated bypass protection device. Therefore, the bypass protection device forms an integral structure, the reliability of the product is improved, and the production cost of the product can be greatly reduced. The stable development of the photovoltaic solar energy industry can be guaranteed.

Description

technical field [0001] The invention relates to an integrated bypass protection device used in the field of solar energy and a process method thereof, belonging to the technical field of electronic component manufacturing. Background technique [0002] With the growing demand for green energy all over the world, and the recovery of the photovoltaic industry with the support of the state, the demand for bypass module junction boxes is growing rapidly, and the requirements for product quality are getting higher and higher. Photovoltaic bypass protection devices are indispensable core components in the solar industry. It is used in parallel connection of battery packs to protect solar panels. Under normal circumstances, the charge generated by the photovoltaic panel flows through the panel, busbar, etc., flows out through the positive and negative electrodes of the device, and then passes through the inverter to convert it into the alternating current required by the market an...
