Advantages of embedded resistors/capacitors components:
- Embedded components can reduce EMI,cross talk and noise from other components.
- Package replacement-Miniaturization.
- Protected against external environment impact.
- less solder joints.
Design- embedded resistors
The design of resistor shape is determined on final resistor required value and embedded resistance material value.
The basic equation for calculating resistance is:
R = Rs(L/W)
R = resistance in ohms
Rs = sheet resistance in ohms/square
L = length of resistor
W = width of resistor
- Sheet Resistivity (Rs)= 50 ohms/square
- resistor Length= 20 mil
- resistor Width= 10mil
- R=50 ohms/square X(20mil/10mil) = R=100 ohms
