Product introduction
LGA stands for Land Grid Array, literally translated as Grid Array package. The main reason is that it replaces the needle-like pins with metal contacts.
Product features
LGA’s packaging technology is the point contact technology (contact), mainly because it uses metal contact packaging technology (LGA) instead of the past needle-like pin type packaging technology. The package is designed as a pin less pad to make it occupy a smaller PCB area. The internal circuit of the substrate can be customized, which can greatly reduce the difficulty of the internal welding line of the package. It provides a convenient and customized scheme for complex multi-function chip design.
Application
LGA is a mature industry packaging standard, commonly used in processors, logic, memory, wearable, 3C digital, medical equipment electronics, security chips and other fields.
