BQ25790: How to optimize the wiring and punching of BGA packages

Part Number: BQ25790
Other Parts Discussed in Thread: BQ25792, BQ25798

Tool/software:

Hi TIer

My customer uses BQ25790 to design low cost portable products. He sees that BGA packaging has to make the PCB produce blind or buried holes, or 0.4 mil aperture, which requires the use of laser or more complex manufacturing process, so this will increase the customer's cost. Any optimization suggestions? I asked the customer to refer to the schematics of our EVM board, and they didn't have a good idea. Please give me some advice. Thank you.

  • Hi Tony,

    Unfortunately, there isn't an optimization for it. The BQ25792 and BQ25798 has QFN packaging, if its applicable for customer need, I'd recommend those parts.  

    Best Regards,
