Original motherboard component + redesigned PCB = Well working?
Redesigning a PC motherboard would take vastly more time and money than just buying a new laptop. The board has many layers and hundreds (if not thousands) of traces. You will not be able to figure ou …

Can I use LEDs without PCB?
Related: What is the purpose of star pcb?
At the very least, running them without a heat sink would degrade their operating life. You can buy cheap bare star PCBs off of eBay. … If you design your own PCB, you can add a thermal pad connected to a ground plane. That won't work as well as a star PCB since star PCBs have an aluminum substrate. …

Is it always possible to reduce the number of layers on a PCB by making the board larger
Henry Ott suggests five EMC-related objectives that a board design should try to achieve. They are:
A signal layer should always be adjacent to a plane.
Signal layers should be close to their …

If RF signals require matched impedance to remove reflections, why do approaches to shunt no...
External noise would be reflected. That's fine; the goal is to keep it out of the IC. The bypass capacitors you put next to ICs are there to provide a clean DC supply voltage. Impedance matching would …
