Transfer Robot Arm

I work as technician in a Singapore semiconductor factory. Here I share my working life as technician.

To move the product from the cassette into machine and run processing - deposit few layers of different metals onto the product wafers. The machine need a robot arm.

This is how the robot arm looks like:

At first glance , it really looks like a Lego toy. But in actual fact, our this machine since it's pretty old technology (history up to 30+ years). We are using this kind of robot arm.

This is how it looks in the machine.

This is how it looks, when the robot arm clashed with the products. Could due to sensor faulty , could due to cassette platform moving, then robot arm sudden extend out of control.

The robot blade bented badly in this case, view from different angle. This must be a bad day as investigation reports will need to prepare before tomorrow production meeting. Sad. Lots of questions will be thrown by all parties...
