How to Attach a Chip to a Breadboard

What you need is a zero insertion force socket. Check here and see if you can find what you need.

The only CD4028 chips I saw listed are the standard DIP package with 0.1" lead spacing that will fit a proto-board. So I could not locate from your part designation which package design you actually have but it sounds like an SOIC surface mount chip. There are adapter boards that allow a SOIC chip to be used in a prototype board; Augat, Vector and others make them. You have to solder the chip to the adapter.

Sounds like a SMT (Surface Mount Technology) chip and not a DIP (Dual In-Line) chip.

One trick is (if you can find one) is to get a DIP socket and glue the chip to the top of the socket, then hand solder each lead to the socket.

Likewise, you can get some header pins (see attached) and do the same thing.

Yep, that's the type of adapter I was talking about. GA

Nice tutorial.

lots of youtube tutorials

Yep, many chips of older, thru the board forms are still available, but in surface mount fine pitch form, not really meant for human handling. Rather for automatic placing and soldering into place.

The same is for learning. Once the the surface mount chip is on a DIL adapter, people with normal hand - eye coordination can take it from there. One caveat: the adapter adds wire length and capacitance to every lead. Can cause trouble over 50 MHz, or so.

What you have is a sop pin whereas you have a dip board, you can sometimes solder the sop pins onto the board depending on whether the solder points are on the side you want. If you can find a part No for a dil socket, I have a few thousand sockets I could look through.

GA! I was thinking about making the same suggestion.

Depending on the type of CD4028 you have, why not buy a dil chip? a BE is 47pence from Farnell.

This is the picture of it. From the end. The pitch is 0.050". It is so small that I can hardly see the gap between the legs, so I think the best advice is to buy the proper chip with the vertical legs. I've seen some pictures of the ones that will be ok.

I will put it down to a learning experience, which is part of the reason for doing this in the first place.

Thanks for everyones input. I appreciate it.
