Staubli's Modern Way of Testing Printed Circuit Boards (PCBs)

Printed circuit boards (PCB) in the automotive industry are subjected to various stringent tests to meet automotive safety regulations. The management of the series of circuit board testing processes is complex and consumes a lot of manpower and production time, which is an urgent issue for end customers. The leading Swiss brand of industrial robots has helped global automation system providers to improve the automotive electronic circuit board testing process. The German system integrator has developed an excellent solution for this testing process - the te|box - with Stäubli's six-axis anti-static robot as the key component, thus eliminating the bottlenecks and pain points encountered by the customer. The PCB test line consists of a fully automated test cell and oven, which is even able to performs high and low temperatures tests from from a low of -40°C to a high of +140°C.

The robots to make the test process more flexible, can be carried out at the same time for low and high temperature testing, which also uses a quick-change system, automatic replacement of robotic arm tools to adapt to different PCB size specifications do not need to stop the line to adjust, and static-sensitive environments, narrow space and high throughput requirements, so that the selection of robots has become a major challenge. The anti-static six-axis arm can effectively prevent the arm movement in space and air friction generates static electricity, resulting in product damage. Equipping six-axis robots in electronic testing equipment means the beginning of a new era of electronic testing and the end of the rigid connection. The protection against static build-up is extremely important, and the robot's flexibility and excellent speed greatly increase the number of tests, successfully helping system providers to meet customer expectations and create a win-win situation.

The Staubli ESD Robot Series is designed to prevent static discharge environments and to safely handle electronic components. The series is grounded on all arm segments from the tool to the robot's base. The robot has a special anti-static coating that conducts electricity to all accessible components and surfaces. The robot can be used in EPA (ESD Protected Area) for a variety of applications including board assembly, inspection of various components, and package testing of consumer electronics.
