* **Cost-Effectiveness:** If you’re on a tighter budget, a **router machine** may offer a **more cost-effective** solution compared to the initial investment in **laser** equipment.
ເຄື່ອງ Router use a rotating bit to cut the pcb along pre-programmed paths. Although there is some mechanical stress and the cut edge may not be quite as smooth as ຕັດເລເຊີ, modern ເຄື່ອງ router are designed to ຫຍໍ້ vibration and achieve good results for many applications. When working with ເຄື່ອງ router , the feed rates and spindle speeds play a crucial role in the quality of cut edge, therefore having the correct parameters is crucial for best results.
5. What Role Does V-Groove Depaneling Play in PCB Manufacturing?
V-groove depaneling is a classic method that relies on pre-scored pcb, which is typically used to cut multiple boards in a panel. This technique is ideal when individual pcbs are rectangular or very close to rectangular, it’s all about making ມືຫັກ efficient. A v-groove machine uses a blade to score a v ຮູບ channel into the pcb along pcb ພ້ອມ the separation lines which makes pcb depaneling refers to simply snapping the boards apart. Here’s a closer look:
