LM4030: Is it possible to apply conformal coating? Will this affect accuracy?

Shinichi Inoue

Part Number: LM4030

Tool/software:

Dear Specialists,

My customer has a question about conformal coating availability.

I would be grateful if you could advise.

---

Is it possible to apply conformal coating to LM4030?

Will this affect accuracy?

I appreciate your  great help and cooperation.

Best regards,

Shinichi

    Hi Shinichi,

    I would not expect the accuracy to be affected assuming the conformal coating does not change the electrical characteristics of the board. However, we do not have data to show whether or not a conformal coating would affect the performance of LM4030, so I cannot provide results to show this to be true.

    Thanks,

    Jackson

    Hi Jackson,

    Thank you for your reply.

    I'll ask the customer to evaluate whether there are any problems with the characteristics after the coating agent is applied.

    By the way, I think there are many use cases of using conformal coating, do you think about it?

    I appreciate your great help and cooperation.

    Best regards,

    Shinichi

    Hi Shinichi,

    I'm sure we have many customers use conformal coating, and we have not received any complaints that LM4030 has had its accuracy affected by it. If you receive such feedback from your customer, please let us know, but I would not expect there to be an issue.

    Thanks,

    Jackson
