DIY SOT23 ZIF socket
« on: October 16, 2015, 11:04:25 pm »
Have you see the price on the ZIF sockets for SOT23!
As little as $25 but as much as $150!!
Now, I don't know if the $150 one included anything else but the pictures didn't show anything.

Since I'm already spending quite a bit on my little project (not thousands mind you, more like a little over $100) I decided to make my own SOT23-8 ZIF to program PICs.

I started with some surface mount RJ-45 sockets.  These particular ones had the contacts molded into a convenient block that was extracted.
I found another type of RJ45 socket that had longer fingers separating the contacts so I used that.  They guide the contacts and align the chip so it can be clamped.
A little wood, circuit board material and super glue holds it all together.  I found a small magnet to hold the latch down.

I still need to solder it to a base that can be plugged into a breadboard but I think it will work.

Hope this inspires someone else to 'do it yourself'.

Thanks,
The pitch is a bit off but tolerances are such that it works.

I use a magnet for my SMD "ZIF" socket.

Note: avoid using on hall effect devices :)

I saw this thread and that inspired me to make the project I kept putting off.

I wanted a pogo pin test jig for testing SMD transistors on the cheap multi component testers you can get online. They do have an SMD pad area but it is rather fiddly and prone to the tweezer snapping and throwing the component someplace you can no longer find so it is not a good option when sorting through a mixed bag of components.

Here's my version using pogo pins and a jig to hold the component in place.

These are some neat ideas.  Lots of ways to do the same thing.
I hadn't thought of having the chip upside down. 

Thanks guys.
