In the design of a power electronic PCB, I want to use a metal PCB for heat dissipation of a TO-220 package MOSFET. To do that I want to mount
I am making a large prototype of a device that requires a large PCB (about 15x20inches). I am able to etch my own circuit board in copper laminates, but I
In common, I use 2 ounce copper as rule for all my PCBs. On a recent board, I am using a 0.5mm pitch, relatively large micro, and noticed the pads
There is nothing about weight in the substrate datasheets I found.
Between CEM-3 or FR4, which is the lightest material ? What is the average weight by surface for CEM-3
I understand that the dielectric material on a PCB (i.e. FR-4) can affect the capacitance of the board. But I don’t understand why is that capacitance significant, and in what
I’m making my first 4 layer PCB (1 signal, 2 GND plane, 3 PWR plane, 4 signal) with impedance control. How do you know what type of material to use? Is
We are a green energy brand which sells solar water heater. All of our products are almost use PCB. And we want to know whether it is poisonous to human
I have a technical question about thermal management with mid-power LED diodes.Do you use thermal vias on the PC board anymore? Either under the LED diode footprint or even around
I have a THERMAL problem when designing a power LED ALUMINUM PCB. I have 10 5W UV power LEDs.Coldwater flows through water heat sink continuously. The problem is the PCB
I am designing a micro-strip antenna with an HFSS toll, what’s the thickness of FR4 substrate that one should take ?
