Nrf52840 EAGLE Library pitch size

[Zian]

Hi,

We are currently at the process of manufacturing prototype boards, the manufacture cannot do pitch size under 0.25mm. They kept telling us that the chip's BGAs exceed that limit, we are using the nrf52840 eagle library from nordic's github. On document, the chip satisfies that requirement, so we don't know what the problem is.

Thank you,

Hello Zian,

I'm not entirely sure what you guys are trying to achieve, so take this comment with a grain of salt or ignore it completely but have you considered using a 3rd party pre-assembled modules that allows for smt soldering?

Might be easier to streamline into your design.

List of available modules here.

Cheers,
