I have a prototype board like this, on which I plan to add some solder traces (the black lines).
I plan to place a BNO055 on top of this same prototype board and solder it in place without using header like this:
It is intended that there is a connection from the Pads to A8,A6,A5,A4 to coincide with Vin, GND, SDA and SCL.
I was wondering if I need to place some insulating material like tape between rows B-G to insulate the breakout board from the PCB ? I intend to have a connection from 3vo (A7) to ADR (H4), and intend to place a connector on K(4-7).
Is insulation tape necessary ? Or is the breakout board already insulated, and the traces being in contact with the board shouldn't matter ? Any other suggestions about what is wrong with this approach ?
The reason for my approach is: 1. I don't have access to any parts or tools to place all the individual components on the prototype board itself, so as a quick hack I'm trying to just place the breakout board on the prototype board without headers (through-hole soldering). 2. I would like to minimize height and footprint.
