    Hello All,

    Need some serious help. One of our designer shows through hole pad and routing for one component. Now this production also done. Now we came to know that component is actually Surface mount not though hole. So how to correct this error, without reproduction/change part.

    You can create a "breakout board," which is an adapter PCB with a footprint to allow the SMD to be soldered on, but also has pins out the bottom that you can solder to the holes in the main board. The breakout board has traces that properly connect the SMD pads to the through hole pins. Properly done, it doesn't look too bad, and works well.

    What is the SMD part number?

    typically called "surfboards" or "breakout board" or "SMT to TH adapters"
    I like this place for that kind of stuff..fast shipping/great selection

    or find a through hole version of the part.. That will be "cheaper"/more professional looking,etc.. for a production run by far.

    You can get adapters much cheaper off EBay.

    But your boss still isn't going to like this <grin>

    (PM me with size if you need a link)

    Is there an issue with through-hole pins aligning to the SMD pins since the SMD is mounted to the back of the board and pins will mirror the surface mount pins.
