66 PCB007 MAGAZINE I AUGUST 2025 Advanced Mapping Possibilities For applications demanding an equal thickness of the remaining web (the precise distance between the end of the depth routing and the bottom surface of the panel), simple constant depth routing is often insufficient because of inherent variations in panel thickness. In such intricate cases, it's imperative to create a "map" of the back-up panel (the bottom surface) before the routing process begins. This mapping involves high-resolution scanning or measurement of the bottom surface topography. The resulting data creates a digital "map" that pre- cisely informs the routing machine about the local thickness variations. The machine's control system then adjusts the Z-axis depth for each routed point according to this map. This ensures that even if the original panel thickness varies, the remaining web thickness is consistently uniform. Vacuum Table With the Adaptor For the most demanding depth routing applications, particularly those involving extremely thin or small panels, or panels with multiple cavities, maintaining absolute panel flatness and stability during machining F i g u re 6 : M a p of t h e b a c k p a n e l s a m p l e. ▼ F i g u re s 7 a n d 8 : Va c u u m a d a pto r m o u nte d a n d u n m o u nte d . ▼ D R I V I N G I N N OVAT I O N
