PCB guidelines for high speed DDR include proper layout, impedance control, signal integrity, and power distribution.
Proper layout is crucial for minimizing signal interference and ensuring signal integrity.
Impedance control is important for matching the characteristic impedance of the traces to prevent signal reflections.
Signal integrity can be improved by reducing noise, crosstalk, and ensuring proper termination.

Capacitor value is a measure of the amount of charge a capacitor can store.
Capacitor value is measured in Farads (F).
Capacitors can have different values such as microfarads (uF), picofarads (pF), and nanofarads (nF).
The value of a capacitor determines its ability to store and release electrical energy.
Choosing the right capacitor value is important for proper functioning of electronic circuits.
I applied via Walk-in and was interviewed in Feb 2024. There was 1 interview round.
A printed circuit board is a board made of non-conductive material with conductive pathways etched or printed onto it for connecting electronic components.
Consists of non-conductive material
Has conductive pathways for connecting electronic components
Used in electronic devices like computers, smartphones, and TVs
Printed circuit boards can be classified into single-sided, double-sided, and multi-layered boards.
Single-sided PCBs have components on only one side of the board.
Double-sided PCBs have components on both sides of the board.
Multi-layered PCBs have multiple layers of conductive material separated by insulating layers.
Examples: Arduino Uno (single-sided), Raspberry Pi (double-sided), smartphones (multi-layered)
