Optimization Strategies for PCB Layout in Mult-functional Robot Design
This document outlines the design considerations for a multi-functional PCB layout developed for a robot by Team 8. The PCB is divided into four functional groups: Digital, Analog, Power Supply, and Motor Control. Key strategies include isolating analog components and wireless transceivers from high-power elements to mitigate EMI effects. Additionally, it discusses the placement of decoupling capacitors and minimizing trace lengths for ICSP connections to enhance performance and reliability. Techniques for heat management and reducing EMI through component placement are also addressed.

PCB layout divided into 4 functional groups • Digital • Analog • Power Supply • Motor control
Analog components • Sensors and the wireless transceiver isolated from high power components to reduce the effect of EMI radiation on the sensors • This helps because the Electro magnetic field intensity decreases exponentially with distance in air.
Microcontroller PCB specifications • Decoupling capacitors placement • Additional capacitors for additional noise • Components of MCLR kept at 6mm • Trace length between the ICSP connector and ICSP pins kept to minimum
Motor Control and Power Supply • EMI due to high switching nature of the currents can be reduced by decreasing the current loops(placing the components closer). • The heat generated by the converters is taken of by the components themselves as both the regulators have large exposed ground pads for better thermal connection to the PCB.
