UFQFPN32 - Stencil recommendations

AMIGD · ‎2024-10-09

Does anyone know where I can find STM's solder paste stencil recommendations for UFQFN devices?

We are using STM32F051K6U6 however the datasheet only has recommendations for the BGA package of this device, not the QFN.

We are getting shorts underneath these device and I wonder if the solder stencil is responsible.

Hi @AMIGD,

Here is TN1224 I think it will be helpful for you regarding the solder paste stencil.

Please give me an update if this TN helped you.

Thank you.
