OPT8241-CDK-EVM: bonding pad off

user1699043

Part Number: OPT8241-CDK-EVM

bonding pad got off, when we did some modification on the OPT8241 board, as is shown in the following figures, black line circled. I want to know if there is any chance to fix it and how to get this fixed.

Hi!

I am afraid that a bonding pad coming off is pretty much irreversible. It is fairly difficult to solder the switch back on.
The switch controls the enable pin inputs of the input current limiting ICs on the board. This is shown on the power distribution page of the CDK schematics.
You could connect external wires to the enable pins and pull them up to keep the board permanently turned on. You will have to rely on unplugging to turn the board off.

Subhash

Hi,

Thank you for your reply.
Do you know which 2 pads are directly connect to these switch pad? So that I could connect external wires.
