DIY SOIC to DIP Chip Adaptors
Intro: DIY SOIC to DIP Chip Adaptors
The world of electronics is moving further and further away from Through-Hole components and towards SMT (Surface Mount Technology) every day. Sometimes this doesn't always go well for the enthusiasts building at home, so we have to adapt.
Literally.
SOIC to DIP adaptors are useful for many things:

SOIC to DIP adaptors are useful for many things:
- For prototyping a circuit on a through-hole proto-board and later converting to SMT
- For saving money with cheaper SMT chips
- Some chips might only be available in SOIC packages
- Programming SOIC microcontrollers without expensive ZIF sockets
STEP 1: Materials and Tools
Heres what you will need to build these:
Materials:
Materials:
- Copper clad board
- Breakaway male strip headers (like these)
- Ferric Chloride etchant (or equivalent)
- Additional supplies for your etching method of choice
- Solder
- Drill
- 1mm drill bit (3/64" is what I use and it works well enough)
- Tin snips or other PCB cutting tool
STEP 2: Etch the Boards
Now, I'm not going to go into detail about etching because it has been done to death here and all over the internet. I use the el-cheapo Magazine paper transfer method. It works great for me and is probably the cheapest possible at-home small production solution.
I have supplied a .docx file with the correctly scaled layout inside, which can be printed on whatever medium you are going to use. The file is available below.
If you're doing the magazine paper method, after printing, ironing, dissolving, and etching, drill the holes for the header pins and cut the boards apart with the tin snips. Trim them as necessary to make them smaller.

STEP 3: Soldering
Take your header strips and break off a 4-pin segment, and solder in place. If you're having a hard time keeping them in place while soldering, you can put them into a proto-board and then place the PCB over top, and solder them in place when held down. Then, gently position the SMT chip with tweezers and solder it in place.
The method I use for doing SMT chips is to place some solder on the pad for Pin 1, then hold the chips with tweezers in place and apply heat so Pin 1 sinks into the ball of solder on Pad 1, and holding the chip in place until it cools. Now the chip is sturdy while the rest of the pins are being attached.

STEP 4: Complete!
Now you've got a sturdy chip that can be inserted into a proto-board, perf-board or an existing chip socket without issue.

But like I said being a hobbyist I just say no to SMT.

It just needs to be plugged across the valley that runs down the center or the breadboard.
I too have enough dip chips saved up, I don't have to worry about the future unless something new comes out.

Unfortunately the world is going SMT with or without us, breakout boards just let us keep living the breadboard dream.

Works for me when I click it, not sure what could be causing your problem.

Just a note to let you know I have added this ( a year ago ) to the instructable:
Comprehensive Guide to Electronic Breadboards: A Meta Instructable
>> https://www.instructables.com/id/Comprehensive-Gui...
Take a look at a bunch of project involving breadboards.

1. Open image in GIMP (it can be found above)
2. Go to Image Settings and change Width to 2.60 inches. Height should auto-scale.
3. Print and fit! Cheers!

I also attached the 555 to one of my completed boards. There's a pic for that too. I'm waiting on my header strips from China/ebay now...
Thanks again!

Can you upload this as DOC? I know OpenOffice can make PDFs for free, and it has great DOC support, so I could make a PDF from that.
