Some online tutorials about soldering TH components, like transistors and ICs, are delicate components and can be easily damaged by heat. When it comes to soldering surface mount IC and
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
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?
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
