Suface Mount Prototyping
|
|
|
Hi Everyone,
I purchased the following Honeywell chipset:
http://www.ssec.honeywell.com/magnetic/datasheets/hmc1055.pdf
....and wanted to prototype a circuit using these chips. I wasn't
expecting these chips to be so small. Geez, I can barely even see the
pins on the HMC1052  . I guess I was thinking for some kookie reason
that I could plug these directly into my breadboard...Oh well....
Obviously, there's no way for me to directly mount these chip on my
board (i'm using the Parallax NX-1000).
Does anyone have any suggestions as to how I might be able to use
these? Keep in mind that I am very new to electronics and not an
expert solderer. I was hoping that someone might be able to let me
know if there's some sort of host socket (or something) I can use so
that I can work with these chips on my breardboard.
Any ideas will be greatly appreciated!
Thanks!! |

On a breadboard,glue it upside down, |
and solder with wirewrap wire. |

The method is called "dead bug"
You superglue it to the PCB upside down in a desired area, and then
use very fine wire to hook up the pins to your other circuit elements.
Remember to pay close attention to pin locations as things get
confusing when "mirrored" as happens with upside down chips.
Also, try to keep you point to point leads short. Fine, high end
tweezers, a *good* iron, and an inspection microscope or desk lamp
with magnifier aid things along. |

One must go much finer than wire wrap wire these days. 30 gauge or
even smaller. Teflon coated "jumper wire" (or called "hook up wire")
or even fine gauge mag wire will work. |

I'm new to this SMT stuff, too. Here's a good NASA best practices pdf
I just ran across. I've found it as a website, too, but I suggest
dwnld the pdf file so you can blow the sucker up to view.
