Redesigned RTU PCB

Redesigned RTU PCB

This was a redesign of existing main board with over 300 components of a substation Remote Terminal Unit (RTU).

There were number of new features that had to be implemented requiring complete new layout of the board. I followed number of safety and performance standards as well as the R&D procedures of the ISO9001 certified company.

Since the board was going through a major redesign, I implemented additional changes to reduce the cost of the board by:

• converting all components to SMT type and press fit connectors
• moving all components to one side
• removing 2 internal layers

I used Protel 99SE to update the Schematics and create brand new PCB layout. During the process I kept detail design log and at the end I supervised conformance testing.
