The printed circuit board (PCB) is the backbone of electronic circuits, and for complex circuits, multi-layer PCBs are utilized to enhance productivity. PCB drilling is a crucial process, especially in multilayer PCB production, and involves precise via creation through laminate material. We know that vias are important conduits that bridge the gaps between multiple layers of PCBs. These are considered the conductive connections in a PCB, especially if it has multiple layers. Without vias, the multilayer PCBs have limited design flexibility and are impractical. In PCB manufacturing, there are ...
Hello everyone, I hope you all are doing well. In today’s tutorial, we are going to discuss the PCB Etching process, a fundamental step in PCB manufacturing. The PCB Etching process is used to remove the unwanted copper from the PCB surface to reveal the desired circuit pattern.
As we know, a PCB board has a complete copper layer in its raw form. We design our circuit in the software(i.e. Eagle, Altium, Proteus etc.) and place the pattern on the PCB board. This circuit pattern is normally protected by the tin plating, as shown in the below figure:
