Bought some SMD IC's by mistake. How to make use of them

I bought 10 parallel shift register IC's and wasn't paying attention and got them in a SOIC SMD package. I've never really used any SMD components before except some 3 pin regulators that are rather forgiving of my soldering.

These are densely spaced leads 1.27mm, what are some options for using them? I see I can buy SMD to DIP style breakout boards but the boards cost more than the IC's did. Given it's a 16pin package and I normally use breadboards for testing and then perf boards for final project are these even viable to attempt to use?

Net cost was under $4 so it's not a big deal to just order more but I hate wasting them, I only ordered 10 as ordering 1 was basically no cheaper.

Yes they will, but eBay has some cheap ones if you look around.

If you want to use them then get a PCB made when you have finished the design.

I frequently use prototyping board with groups of through-hole pins and a few SOIC footprints on the same price of PCB material. Makes it very easy to integrate SMD parts with a largely hand-prototyped design - of course, it's most compelling when you need to use one or more devices that are only available in SMD packages (which is the case with all the best components these days)... They are by far my favored way of prototyping these days.


Now, you might be thinking "Wow, sounds perfect, but where can I get some of those?" Well, funny you should mention that... because it just so happens that I sell just such a design! https://www.tindie.com/products/drazzy/2-x-4-prototypingproject-boards/

"densely spaced leads 1.27mm,"

Ha ha, that is not dense. 0.5mm like on the 2560 chip is dense.
Normal thru hole parts are 2.54mm, so yours are just 1/2 that. Not bad at all.

Here are 24-lead parts, 15 pieces for $6. Will have some pins you are not connected to.

You can use these parts with 0.05 inch perf board.

But for an even cheaper method, take some strip board and with a scalpel cut out the copper between the holes in a strip. Then you have 0.05" strip board.

Very interesting idea, that stripboard mod. It’s one that hadn’t occured to me.

If you want to talk about tiny, look at the MCP4017 digipots. They use an SC70 package and I reckon that you could fit 5 on a man’s little fingernail. Add into the mix tired old eyes and less than perfect lighting and you have an interesting job to do.

Thanks, I made it up myself some years ago. Going between the holes is quite easy as the holes stop the blade from slipping. I normally do two cuts and then remove the copper with the blade.

I have had what I thought was a good look round, but can't find a source of it in the UK. Any pointers please Mike?

Glue them to your front teeth and go out in public, these days, people need a laugh. ;D :smiley:

Thanks!! Genius, lol. As an update I ordered some in a DIP package as of all the great ideas none were cheaper than just buying more IC's, lol. But this strip board idea is gold! I use those so I don't mind buying more and having them on hand when/if I need to use the SMT ic's.

There are other sizes too if you back up from here.
