Interfacing tiny IC packages?
Archiver
Posts: 46,084
Guys,
Nowadays the IC packages get smaller and smaller. Some do have larger
outline brothers, so do not. Recently I got some sample from MAX and first
when opened the box, thought that they have forgot to put the IC there - so
small they were.
Is there a good method of dealing with these tiny brats in a breadboard type
environment? Anyone came up with some kind of an adapter for these things?
I have some ideas myself, but just don't want to invent the bicycle, so to
speak.
Any suggestion will be greatly appreciated.
Alex.
P.S. I posted this on basicstamps, basicx and OOpic groups.

you can buy them from DigiKey. They don't have stuff that handles the
big stuff. Personally, I wish I knew a better way to handle the big 144
pin packages and so forth. We make custom PC boards to handle them, but
that's not very handy.

Warning: blatant advertising follows:
I offer some little adapter PCBs for SO-8, SO-16, SO-28 for cheap. I
haven't done SOT-23 types yet but will sometime in the future.
The adapters come as a small board containing several adapters. You have
to cut them apart with tin snips, solder on the SMT chip and add pins (I
use cut-off resistor leads). The boards are double sided with plated thru
holes and solder mask.
The SO-8 adapters take narrow (0.15") and wide (0.20") chips up to 8 pins.
The SO-16 adapters take narrow body (0.15") chips up to 16 pins.
The SO-28 adapters take wide body (0.3") chips up to 28 pins.
I currently have several different combinations:
5 - SO-8 adapters $1.00 US
2 - SO-8, 1 - SO-16, 1 - SO-28 $2.00 US
3 - SO-8, 2 - SO-28 $3.00 US
Add $1.00 US for shipping for up to 5 of the above cards.
9 - SO-8, 4 - SO-16 $4.00 US inc shipping
3 - SO-8, 4 - SO-16, 2 - SO-28 $5.00 US inc shipping
3 - SO-8, 3 - SO-16, 2 - SO-28 $5.00 US inc shipping
Important note about the SO-8 adapters: the SMT part is mounted on the
UNDERSIDE of the adapter. There just isn't enough room to mount a 0.200"
wide SO-8 with gull wing leads between 0.3" DIP spaced leads.
Please contact me via PRIVATE email if you can use any of these.
