8-pin SO8 to DIP for bread board testing ...

Beau Schwabe · 2010-06-06 08:09

...I'm sure they exist, right? I've always been a cheap skate and made one myself, but what a P.I.T.A. ...this time around, the third attempt was a charm. Fortunately I ordered Ten IC's and at the moment I only need One.

I was just wondering if such a beast existed, I don't know that I've ever seen one.

Edit: Well, I did find two different versions on E-bay, but they both look like they have a bigger footprint than what I was able to do by hand. Hmmmm

Nice soldering job on such a tiny part!

Roy Eltham · 2010-06-06 08:42

These guys seem to have every kind of adapter board possible, and even offer to solder the chip(s) on for you for a fee if you send them the chip(s).

I just bought a panel of SSOP-to-DIP boards from Mouser. It was rather spendy; but, on a per-board basis it was much cheaper than buying individual adapters, and it will last me a long time. Here's the part:

www.mouser.com/ProductDetail/Bellin-Dynamic-Systems/B516/?qs=sGAEpiMZZMviNQmaL%2fXs4vW7tjGJ%252bLM1

The boards are well-made and easily snap from the panel. The adapters come in other flavors as well.

HollyMinkowski,

"Nice soldering job on such a tiny part!" - Thanks, but I can tell that my eyes are getting older. 12 years ago I soldered small stuff like this all the time and could do a better job without wearing any glasses or using a magnifying glass, now if I didn't have glasses there wouldn't be a snowballs chance in HE{double toothpicks} ... most of it is technique though. i.e. the small wires are soldered to the IC before it's ever put into position, and THEN the wires are soldered to the .1" pins.

I keep some of those Bellin Dynamic boards for sale on eBay in small quantities for hobbyists at a very reasonable prices.

Also available in 3s and 4s, just check my other items.

Rick, I thought about doing the same with my SSOP boards to help pay for the ones (i.e. most of them, probably) I won't use. Do you get any takers at $4.95? (Still way cheaper than Aries adapters.)

-Phil

RDL2004 · 2010-06-06 18:24

I started selling these last summer just to get rid of the 138 I didn't need but had to buy for a project [noparse]:)[/noparse] I think I've bought 6 or 7 of the full sheets from Mouser since then.

These guys have a good mix, that are good quality and shipping is cheap
www.futurlec.com/SMD_Adapters.shtml

Unfortunately everything including their soic8 are for 0.6" instead of 0.3" spacing

Sending $20 on a good mix of adapters has been one of the best investments I ever made. I've tried soldering a 100 pin TQFP LPC to get a feel for what prototyping with the prop2 will be like

hover1 · 2010-06-06 21:47

Looks like he had 29 sets sold and more than 10 left. Nice price. Set of 5/$4.95 + Free Shipping!

The Bellin Dynamic boards are very good quality, same pin spacing as a standard .3" wide DIP and pretty easy to solder. I use the "drag a big blob of solder followed by solder wick" method. Here is the first one I ever did:

attachment.php?attachmentid=70931

I've actually sold about 800 since I first started last spring. I had to re-list a few times because even if you select "good until canceled", eBay will still end it if you let the quantity available drop to zero.

These little boards are very small and light, and since I don't include the header pins I can just mail them in a regular envelope like a letter. First Class Mail usually only takes a few days to get anywhere in America. That's probably the only reason people buy them. You can get similar items from overseas for a little cheaper, but they take weeks to arrive.

I realize its an old thread, but Im looking for kinda the same thing. Anyone here know that the item number for these from Mouser or Digikey is?

SOP8-SOIC8-SO8 ZIF Socket Adapter:

CHIP_PROGRAMMER_SOCKET_SO8_SOP8_to_DIP8_SOP8_DIP8_adapter_Converter.jpg

Im more interested in just the black adapter socket on its on so I can find other sizes and make my own boards, but if Mouser has the whole units sold as is, thatd be okay too I guess.

RDL2004 · 2013-03-15 13:26

Those type tend to be pretty expensive from places like Mouser. They have some that fit from 8 to 20 pins, but over $80. A plain 8 pin SOIC to DIP is around $20.

http://www.mouser.com/Connectors/IC-Component-Sockets/_/N-211lk?P=1z0wxos&Keyword=SOIC+socket&FS=True

I still sell the plain boards (the link in the previous post is out-dated).

http://www.ebay.com/sch/1518kyt/m.html

You can get them cheaper from China or Thailand, but mine usually arrive in just a few days.

I found a USA seller on ebay and bought 5 of those for $4.79 shipped.

The socket adapters I just went ahead and bought a couple from China for less than $5. Ill work with the solder kind first. Now to find the art number at Mouser for the pin header strips...

RDL2004 · 2013-03-15 14:59

Yeah, that would be me

At one time I tried selling the boards with the header pins included, but I couldn't send them in a letter, the Post Office's machines just tore them up. I'd have to use a padded envelope and that would add over $2 to the total cost just to cover the higher shipping cost and the cost of the envelope. That would be in addition to the cost of the pins themselves.

Awesome. Well I look forward to getting them from you then! Any chance you could tell me the part number for the pin headers? Hopefully from Mouser since thats where I buy all my other stuff.

SOP8-SOIC8-SO8 ZIF Socket Adapter:

There is a general trend to stock the larger-superset ZIF, so for 8 pin 150 mil, that would be SO16N
You'll see the plastic is all 16 pin based anyway.

These are something I had not seen before :
http://www.aprilog.com/ZIF_SOICpads.html
- it is a ZIF socket plus a stalk-plug-SMD 'foot' - quite nifty, but the leverage would worry me a little.
I guess you remove the whole unit, to replace the chip, then carefully replug ?

they also sell just the ZIF,
http://www.test-socket.com/index.htm#652B0082211
and $8.00 seems a good price.

RDL2004 · 2013-03-15 15:09

Here's some that will work, already in 4 pin length so you don't have to do any cutting or snapping. It should give you a start anyway.

Awesome, those sockets alone I was looking for! Ill pick up a couple of those from that place as well.

Perfect, exactly what I wanted. Thanks man!

Funny, Id never before thought of coming to the Parallax forum for help. I literally live down the street almost from their Rocklin, CA headquarters and their Basic Stamp was my first intro to micro-controllers back in '94. I should have been hanging around here long long ago.

Adapters for just about anything can be a gotcha experience.

I went looking for some S08 to DIP and purchased some 20 pin devices that I cut in half with a hacksaw. Seemed less costly and worked fine. I added by-pass caps with surface mount devices.

Huh, never worked with that style of pin headers, but I might pick up a few just to try em. They look thinner than the "normal" kind.

Advantages of the machine variants are smaller PCB holes, and they can plug directly into Machine Pin IC Sockets, and normal Dual Wipe IC sockets

Disadvantage is they are rather easy to snap off...

I've found you can insert the standard sq pins into the much cheaper Dual Wipe (AMP) socket, on a 'one way' basis.
(ie once you use the Sq pins, a normal IC is too loose), but that is managed by using a 'permanent' Dual Wipe socket as a transition element, so you have [SqPins -> DualWipe] -> target PCB socket

That then gives you the strength of sq pins, and the cheap/easy replacement of a Dual wipe socket.

Gotcha. Well since I will only be using these adapters and pins for breadboarding while prototyping I guess ill be better off sticking with the standard square pins.

Tracy Allen · 2013-03-16 13:08

Here is another one, from Sparkfun, which looks pretty much the same as the one from ebay.
https://www.sparkfun.com/products/117

Note that the pins are different diameter on the two sides--0.018" on one side and 0.025" on the other. Machined pin sockets can accept a range from about 0.015" to 0.025", but breadboards prefer the larger size.

Individual pins are also an option, and Mill-Max makes a huge variety to choose from. They are very expensive until you buy in the thousands, and they are hard to load unless you have a jig or very steady hands. E.g. part numbers 3114-2, 3115-2, 3117-2. It's good for a low profile result.
