LP8550 SDBGA balling/reflowing...

Other Parts Discussed in Thread: LP8550

Hello Friends,


I was wondering if anyone had experence using LP8550 which comes in SDBGA package. I can't tell if they come with balls or do I need to ball them or do I need to just use some solder paste and reflow? Also, where do you think I can find a stencil for soldering LP 8550?


Thanks!

    Hi Jay,

    There are balls in the DSBGA devices, you do not need to ball yourself them.

    You could search the application note "an-1112 dsbga wafer level chip scale package" from ti.com for more information.

    Thank you,

    Sami

    Hi Sami,

    Thanks for your reply. It seems that one may not have to ball the LP8550 BUT would have to print Soldering paste on the PCB. Do you know a good source of stencil that would be good for printing soldering paste for LP8550 (5x5) DSBGA? Can I obtain it from IT?

    Below is what I see in the document you mentioned:

    Surface Mount Assembly Considerations

    DSBGA surface mount assembly operations include:

    • Printing solder paste onto a PCB.

    • Component placement using standard pick and place equipment.

    • Solder reflow and cleaning (depending on flux type). 

    Thanks,

    Jay

    Hi Jay,

    I am sorry, but I do not have recommendation for stencil manufacturers.

    Thank you,
