BQ78350-R1: How do I remove resistors from the EVM board?

Part Number: BQ78350-R1
Other Parts Discussed in Thread: BQ76930

I'm using the bq76930 EVM board to develop a BMS solution for an 8 cell battery pack. The Users Guide contains instructions for configuration of the board to support 8 cells, including instructions to remove some Input and Balance FET Gate Resistors. Before I go and hack into my board, I just wanted to check how you would recommend doing this. Does it literally mean to unsolder and remove the SMD resistors? I'm just a bit concerned that I might not be able to neatly remove such small devices from the board. Is there some technique(s) you can recommend?

Thanks

Hi Mike,

That's correct, it is recommended to remove the resistors. 0805 resistors are used to make them a little easier to remove then some of the smaller components on the EVM. I know this is still pretty small, but anything bigger would require a large amount of PCB space.

Best regards,
Matt

Thanks for clarifying that Matt. I really wanted to be sure that I should physically remove those components.... and you've confirmed that is indeed the case.
