Can Vias be Drilled Through Pads? In PCB design, whether vias are necessary depends on the specific scenario and process. In some cases, drilling vias through pads is necessary. For example, to improve heat dissipation for large devices like MOSFETs, vias are often drilled on the backside of the pads. In this case, the holes should be evenly spaced to ensure uniform heating. However, the biggest problem with this approach [...]

Why do conductive agents need ultrasonic dispersion? The use of ultrasonic dispersion technology to uniformly disperse conductive agents (such as carbon nanotubes, graphene, Ketchen black, acetylene black, etc.) is crucial for preparing high-performance electrodes, especially in the fields of lithium-ion batteries, capacitors, etc. Conductive agents, especially nanoscale materials such as CNTs and graphene, have extremely high specific surface area and strong van der Waals forces, making them prone to agglomeration [...]
