A pneumatic windshield clearing system for enhancing the safety of operating a vehicle in difficult environmental circumstances without the distraction of wipers. The bond pads are directly connected to the corresponding first vias without the use of a solder and without the need to form a solder wetting layer on the bond pads. The apparatus also includes sequentially operating forming mechanisms for precisely forming the precursor sides of the precursor contact into a final end product configuration. The computing device is required to communicate with a data storage device to dynamically load the required data from therein. When the integration result shows that the battery is charged totally after the highest voltage becomes higher than 4.
