Embedded Copper coin and RFI Metal Backed PCB

Thermal management is very crucial in PCB design to transmit the heat of the PCB board with some critical high power components assembled. The four methods of thermal management 1. Thermal Vias,They can be mechanically drilled blind or through vias. 2. Laser, stacked micro-Vias, become more common, especially with low i/o pitch components. 3. Coppr … Continued

The stackup for 90 ohms impedance for USB

More and more PCB designers are interested in impedance track for USB circuit board of 90 ohm impedance. For 90 ohm impedance, there are two options of circuit track to get that: One option is to get 90ohm impedance by single-end impedance track, with stack up as below: The other option is by differential impedance … Continued

DFM Report

When you finish designing a new PCB, congratulate your work. But it is only the half of success as the next importance step is that the design must be facility to be manufacturing. It will get you high cost and poor yield once your design is very “complex” and “high density”. Weller is your ideal … Continued
