PCB milling uses a rotating endmill tool to cut away unwanted copper from a board to fabricate traces and isolation. Selecting the right milling bit is crucial for achieving good routing quality and productivity. Key bit parameters like diameter, tip shape, coating, and material significantly impact performance. This article provides guidance on choosing optimal PCB […]
Read articlePower supplies are vital components that provide the operating voltages and currents required by electronic circuits and systems. Selecting the appropriate power supply and mounting technique is an important part of the overall PCB design process. Power supplies come in different forms like AC-DC wall adapters, DC-DC converter modules, and open frame power supplies. Most […]
Read articleSwitches are essential components in a wide variety of electronic devices and equipment. They allow the user to control and interact with the system. The two main ways switches are mounted and integrated on printed circuit boards are: Each method has its own set of advantages and disadvantages. Selecting between PCB or plate mounted switches […]
