Case Study — Die Bonding Machine

Client requirementOur client required an automated die bonding machine that could pick Micro-Electro-Mechanical (MEMs) die from a glass handle wafer and place a specified number of them onto a prepared, non-rigid laminated substrate to within 4 micron accuracy in three axes.

The machine was for use in a cleanroom environment and a fast cycle-time was critical.

Our roleWe designed the machine to automate both the pick and place functions, with an integrated shuttle linking the two stages. To achieve this, the machine incorporated the following technologies:

• 4 motion axes on the picking stage, 4 on the placement stage and a shuttle with a cleaning system – totalling 11 motor axes

• Control architecture using a high-performance Beckhoff® control system acting as the PLC , motion controller and operation of 14 separate pressure and vacuum functions

• Two integral rack-mount PCs for control of vision analysis from 4 cameras, HMI functions and Manufacturing Execution System (MES) interaction

• Sub-micron resolution vision measurement system for accurate die placement

• Intuitive operator and maintenance interfaces with easy control of process parameters

• Full integration with MES and wafer metrics systemsDie Bonding Machine - pick stage
