The equipment used is a solder paste printing machine, located at the front of the SMT production line; Teach you to write the title of printed circuit board component products.
Photovoltaic cells are electronic devices that convert high-voltage batteries (ThyHSB) into the DC voltage or DC battery required for energy solar panels. The applicable sections are listed below.
Photovoltaic Energy storage uses the characteristics of high power and small size of photovoltaic cells to realize photoelectric conversion, so as to realize the storage function of Low voltage.
Note: Most high-voltage side systems without a backplane adopt a modular architecture, which is directly connected from the front or back.
● Shielding structure: Wiring at the power source can cause severe interference. (2) Shielding of the shell: The metal shell is used for shielding, and wires need to be routed inside the shell. (3) Shielded enclosure.

External shielding structure: The main purpose is to wrap the shielding layer around the shielding cover, which can have high EMI electromagnetic shielding efficiency and can be directly protected by the casing, but there is a shielding risk. (2) Protective shell: mainly composed of.
● Shell: The main purpose of a protective shell is to protect internal electronic equipment and components from external impacts, accidents, electromagnetic interference, fires, and high-frequency electromagnetic wave hazards. For example, lightning Electromagnetic pulse can prevent internal electronic equipment, electronic components, circuit boards, etc. from lightning hazards.
● Shell: The main function of a protective shell is to enhance the insulation strength of internal components, increase the oxide layer on the contact surface of the conductor, and play a protective role.
● Shell: The main function of a protective shell is to protect internal components from external damage or the influence of high temperature or mechanical physical environment.
