Major geek alert. If you find your eyes glazing over as you read this, you are perfectly normal. My contribution to Weekend Reflections #262, The Weekend in Black and White 3-october-14,  and I heart Macro #73.

BGA is an acronym for Ball Grid Array, a means of electrically attaching an integrated circuit to a circuit board. Basically, every electronic device you own employs this technology during the manufacturing process. The little balls are solder. The integrated circuit is attached to the circuit board, heat is applied, the solder melts and forms an electrical bond with the circuit board, allowing the electrons to do their thing.  Way cool.

I decided to marry technology with artsy-fartsy. I shot this with a 100mm macro lens with 65mm of extension tubes. The aperture was f2.8, but the extension tubes brought the aperture closer to ~f5.6.  Monochrome conversion and processing in Silver EFEX Pro



Need a better perspective?  Here’s the IC shown next to a US dime (taken with my cell phone).

Need a closer perspective, this shows all the little solder balls (64 to be exact).



That concludes this week’s geek lesson.

    Wow!!! Who knew Geek Art could be so darned cool?!!! Love this…very creative….

  7. Love the first photo and appreciate the information in the other two. How cool to combine electronic technology with art!

  8. Margaret says:

    Very creative reflections

    That is such an intriguing picture… Thanks for the explanation, I would never have guessed what was photographied here… You did it with great art ; it is not that obvious to find beauty in such a pragmatical object of current use…

  10. Felicia says:

    that’s cool. I didn’t think it was that little until you showed the last two images.

  11. Christian says:

    Great capture, like the first shot with the solder balls.

  12. LonettA says:

    Excellent! Very creative and artistic photos!

  13. Loved your lively explanation of this. I read every word. You have united engineering and art well. Great photos.

  14. OH MY! I see I still have much to learn!

  15. You’re right — very trés cool! Just amazing!

  16. Mary says:

    FAscinating photos! Great!

  17. James says:

    Amazing and beautiful macro!

  18. Pat says:

    That really is “artsy.” It would look great blown up and hanging in a gallery.

  19. Pat says:

    Very cool!
