This product is an SOIC to DIP adapter with a twist. These have our patented "ez" technology which means that soldering the surface mount component is simple, and as with all of our "ez" boards, we are the only company with a patented solution for easily soldering surface mount parts. Included in the package are .65mm pitch adapter boards for 8 leads, 20 leads, and 28 leads. The 20 and 28 pin boards also include room for 0805 SMT components such as a bypass capacitor and pads for easy access to a ground. This board was supposed to have "EZ" technology but came back from the factory without "EZ" or with less "EZ" than our Q/A would accept. They were rejected by us for this reason. For someone who can solder surface mount without the help of "EZ", these boards are a bargain. There are no returns on these boards, all sales are final.
