Case details
The characteristics of new energy automobile industry and its product process requirements:
New energy automobile refers to the vehicles that adopt unconventional vehicle fuel as a power source(or use conventional vehicle fuel and adopt new vehicle power devices),it integrates the advanced technology of vehicle power control and drive,and forms the vehicles with advanced technical principles,new technology and new structure.
The core technology of new energy vehicles is the"three electric",that is,battery,electric drive and electronic control.And the most core is the electronic control module.
The electronic control system should have high control precision,high dynamic response speed,and provide high safety and reliability.This requires that the electric control board not only has reliable welding quality,but also can withstand high frequency vibration and wet environment after installation and fixed.
The electronic control module is filled with glue,wrapped with glue,and then baked to allow the glue to solidify,which can effectively cope with vibration,humidity and other harsh conditions.The quality of the glue curing process directly affects the quality of the electric control system and the final quality of the control parameters.
