FlexLink offers a complete line of PCB handling units which incorporate standard assembly features throughout the product range. The PCB product line incorporates modular stand-alone units that are truly independent from other modules in the system. Each module has an on board control system which allows the unit to function independently. Each module is able to be linked to other modules in the system by utilizing their up line and down line SMEMA communication. The modules can also be linked to a higher level monitoring or routing system by utilizing a host control system.
