'[AD]: SMT or DIP adpater boards for sale'

I offer some little adapter PCBs for SO-8, SO-16, SO-28 for cheap.

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.

Dear Dwayne,

Just a quick question: maybe I'm not thinking straight but how does
mounting the SO-8 part on the underside of the adapter solve this problem?
The leads are present on the underside, too, aren't they?

The SO-8 part is rotated 90 degrees.  That way, the SO pins don't interfere
with the DIP pins.  Putting it on the underside of the adapter PCB resulted
in the shortest traces.
