Mounter: also known as "Surface Mount System", "Surface Mount System", in the production line, it is configured in the dispenser or screen printing machine, is by moving the Mount head Surface Mount components accurately placed on the PCB solder pad. Divided into manual and automatic two. Automatic SMT mounter is used to realize high speed, high precision and automatic placement of components, is the most critical and complex equipment in the entire SMT production. SMT mounter is the main equipment in the SMT production line. The mounter has developed from the early low-speed mechanical mounter to the high-speed optical mounter, and to the multi-function, flexible connection modular development.
