What are the advantages of PCB Step Slots? In what areas are they usually used? What are PCB Step Slots? A PCB Step Slots are special design element on a printed circuit board (PCB) that creates a series of slots or steps of varying heights along the edges of the PCB or in specific areas […]

Copper half-hole PCB is a special kind of PCB board, which is characterized by plating on one side of the board to form a layer of copper, and then half-hole processing where needed, i.e., drilling holes on one side of the board but not through the whole board. This type of PCB board has the […]

How does the PCB manufacturing process achieve a 4-layer board doing 50 ohm pcb impedance? PCB impedance is the impedance formed by the capacitance and inductance of the insulation and wires around the signal lines on the PCB board. The size of the impedance depends on the frequency of the signal and the design of […]
