EEVblog #181 - Dead Bug Prototype Soldering

Dave show you how to solder a small 3 axis accelerometer LGA surface mount chip "dead bug" style onto a microcontroller prototyping board. This technique allows you to easily prototype projects using tiny SMD components designed only for reflow soldering.

ok dave i love the idea but what about us cafeen adicts out there ( in otherwords) how do you not shake a 6 inch long soldering iron at that size.. and how do you get a tip that small hot enough....

not to minchen where do i get a tip that small O.o

@Zagroseckt That tip isn't small, it's pretty huge, standard several mm chisel tip, but as you can see more than good enough for the job. I have much smaller tips. I have a pretty steady hand, but this is not a really small job, so should be doable by almost anyone. More shaking apparent in the video than I'd usually have, trying to talk, think, and solder and do it all while under the camera through the LCD screen.

Amazing! You have the hands of a surgeon.

Thanks for the video! I used the method on a LIS331DLF (3mm x 3mm LGA16)

It worked great. I used the 0.1mm diameter strands from a multi-strand wire.

I like technique, but isn't putting a 3 axis accelerometer upside down a problem? At the least, you'd have to change your Z axis code later I would think.

Really good mod, i've used this method on a small BGA package, takes alot of patience and loads of flux, hey dave have you ever tried using silver kynar wire ? it makes for a great looking result :)

now try doing the same thing with ADXL312 chip. Good luck ;) its in LFCSP 32 pin package

@GiorgioCapocasa Glad to hear it worked for you!

[GiorgioCapocasa]

@GiorgioCapocasa Update: I've just made it :D

The joints are not nearly as smooth as the ones in the video, but the thing definitely works :)

Thank you, Dave!

Well done Dave, love your videos

[GiorgioCapocasa]

Good :) I'm going to do this in a few days: just gotta get some fine solder.

Thank you, Dave!

i learn so much by watching your vids. thanks!
