How do you use an LCC SMD device - holders or carriers or ??
 

Greetings,

I would like to use a ceramic 8 lead LCC device (accelerometer) in a
project but wonder on the best way to mount and use it in a one-off
project? The device is 5x5mm square, three contacts on each side and one
contact on top and one on the bottom (total 8). So we are dealing with 1mm
spacing - eeek! ;-)

Are there snap in holders which can be used to mount these devices and
prototype with them, sort of like chip sockets for 14 pin DIPs, with wire
fanout to pads for soldering or connections?

I have searched online, but the closest I have found is the surfboard
series for surface mount devices (digikey etc.). This still leaves the
issue of soldering in such close and tiny spaces. Given $20+ per device,
I would like to find something which would allow direct snap in mounting.

Is there such a device available? Who stocks and sells them?

Thanks very much for your help in this project!

regards

Is that the ADXL202? I made a little PCB for it, similar to the one used
for the evaluation kit. Soldering the device was a bit tricky (I should
have used solder paste) but I managed it with a fine tip and a
magnifier. You are very unlikely to find a socket for it, it just isn't
suitable for one.

I used a SMD prototype board with the pads 1.27 mm apart. As it are only 3
pad, you get away with the difference in pitch.

Thanks for the tips - glad to hear that it has worked for others ;-)
I have read up on the SMD use tips on several homebrew sites, but I'm not
sure my hands or eyes are good enough to do this. I'm just amazed there
aren't some snap in setups, esp. given the cost of some of these devices.

regards and best wishes to all

For 'normal' SMD work I use one of these big magnifying glasses with a
fluorescent tube around it, a fairly standard article. If you can not find
then, you may also look in a shop for needlework. For finer work and
inspection, I use a 20x stereo microscope, bought for about $30 on Ebay. As
I am 50, my eyes are slowly getting worse. Soldering with a temperature
controlled Weller and 0.5 mm tin.

Succes, Wim
