In this tutorial we are going to learn about Why Use Buried Resistor in PCB ?
Buried resistor technology replaces discrete resistors with thin film planar resistors laminated within multi layer PCB. Space previously occupied by discrete resistors may now be used for additional components, trace routing/eliminated to create smaller, denser boards. Using buried resistors can significantly shorten signal paths. This results in reduced lead inductance, shorter signal paths, & improved impedance matching. Assembly costs can be reduced when buried resistors replace enough discrete resistors on a board.
Uses of Buried Resistor in PCB Design
- In PCB Buried Resistance can Improves line impedance matching.
- In PCB Buried Resistance Reduces signal paths & series inductance.
- In PCB Buried Resistance Reduces cross talk, noise and EMI.
- In PCB Buried Resistance Enhances performance of cost-effective resistor technology in high speed high density circuit layout.
- In PCB Buried Resistance Eliminates discrete resistors.
- In PCB Buried Resistance Lead free compatible.
- In PCB Buried Resistance Stable through a wide frequency range 20+Ghz.
It can use of increases the active component density, and improves signal routing through the elimination of SMT vias and line impedance matching and Buried resistor can also use for reducing Electromagnetic interference (EMI), noise, Crosstalk and that can maintain the size of the PCB assembly.
