    • Why Multilayer PCB Are Even Layers?

      PCB board has one layer, two layers and multiple layers, among which there is no limit on the number of layers of multilayer board. Currently, there are more than 100 layers of PCB, and the common multilayer PCB is four layers and six layers. So why do people say, “why are PCB multilayers m...

    • Temperature Rise of Printed Circuit Board

      The direct cause of PCB temperature rise is due to the existence of circuit power dissipation devices, electronic devices have different degrees of power dissipation, and the heating intensity varies with the power dissipation. 2 phenomena of temperature rise in PCB: (1) local temperature rise or...

    • Several Multilayers Pcb Surface Treatment Methods

      Hot air leveling applied on the surface of PCB molten tin lead solder and heated compressed air leveling (blowing flat) process. Making it form an oxidation resistant coating can provide good weldability. The hot air solder and copper form a copper-sikkim compound at the junction, with a thickne...

    • Notes for copper clad Print circuit board

      The CCL (Copper Clad Laminate) is to take the spare space on the PCB as the reference level, then fill it with solid copper, which is also known as copper pouring. The significance of CCL as below: reduce ground impedance and improve anti-interference ability reduce voltage drop and improve powe...

    • What is the Relation Between PCB and Integrated Circuit?

      In the process of learning electronics, we often realize printed circuit board (PCB) and integrated circuit (IC), a lot of people are “silly confused” about these two concepts. In fact, they are not that complicated, today we will clarify the difference between PCB and integrated circ...

    • The Carrying Capacity of PCB

            The carrying capacity of PCB depends on the following factors: line width, line thickness (copper thickness), allowable temperature rise.       As we all know, the wider the PCB trace, the greater the current carrying capacity.       Assuming that under the same conditions, a 10 MIL line ca...

    • Common PCB Material

      PCB must be fire resistant and cannot burn at a certain temperature, only to soften. The temperature point at this time is called the glass transition temperature (TG point), which is related to the size stability of the PCB. What are the high TG PCB and the advantages of using high TG PCB? When ...
