Abstract
A printed circuit board (PCB) drilling apparatus that greatly increases the speed, accuracy and depth of the drilling process as well as increasing the life of the drill bits by decoupling the reactionary forces encountered in the positioning and drilling functions of the apparatus in the x, y and z axes from the components that accomplish the positioning, measuring and drilling of the stacked printed circuit boards. The part of the apparatus that moves and drills as well as the feedback position sensors are mounted to a set of vibration isolation pads that absorb the vibrations that would disturb the feedback sensors. Additionally, the force frame of the apparatus that experiences the reactionary force movements are decoupled from the metrology frame of the apparatus that house the feedback sensors, also increasing the throughput and accuracy.
