[0002] BMS circuit board and housing pressing fixtures are specialized tooling designed for precise assembly of both components, widely used in the electronics manufacturing industry. Through precise structural design, they ensure accurate positioning and even force distribution of the circuit board during pressing into the housing, preventing damage due to misalignment or excessive localized pressure. Using pressing fixtures not only significantly improves assembly efficiency and reduces human error but also ensures product consistency. Suitable for mass production scenarios, they play a crucial role in the assembly of products such as mobile phones, computers, and smart home appliances.
