How is my Robotron is working with only 3.2 volts?

OK, so what does this part of the title mean then?

DIP 16 Pin IC Clamp IC Test Clip


Before I bought it I asked them if it was a DIP test clip and they said:

we have tested this model on Programmer Testing Clip SOP SOIC 16 SOIC16 DIP 16 Pin IC Clamp IC Test Clip, if your device model is line in with out title list, it should be work well.
Thank you and have a good day.

There are many Chinese Auctions on Ebay with this title.
I believe it to be a mis-understanding.

You need something like this -> (note the "larger look" and relative pin spacing)

Where smaller DIPs are 0.3" pin spacing (side to side) defining the clip width:

But hey, if you want to believe the Chinese over this Canadian, that's OK with me. :)

OK, they screwed up the title and screwed up in the messages we exchanged through Ebay. That's really lovely.

It's not a matter of believing, it's a matter of me knowing nothing about the subject and learning as I go.

I will message them back and tell them their title is BS and now I get to throw away the item they sold me.

Thanks man. And if you know of any reasonable places to pick some of these up of various useful sizes for arcade work, please let me know. I'm not keen on spending $15+ / clip when I'd probably need 5-6 different sizes.

You can use larger number pin ones for smaller packages.

For example, if you have the 24pin one, you can carefully put it over a 14 or 16 or 18 or 20 or 22 pin DIP and still measure the pins as it will still fit over the smaller package. Just have to know where pin1 is ... A little more inconvenient but do-able.

But remember, 0.3" wide vs 0.6" wide ICs need compatible width clips.

Oh, that's an awesome tip!

Thanks!

That doesn't always work. There are other components that usually get in the way such as caps, or IC's that are next to it.

I ran into that issue with my AR81 and had to get a smaller size for the 14 Pin chips (I use a 16 for those and I have a 20 for the rest) because some boards (like Williams) have other components in the way that prevent you from clipping onto the chip.

Does it go the other way? Can I use a 24 pin clip on a 30 pin chip?

And one other question for both of you. On the soon-to-be-thrown away SOIC clips that I bought, the spring's clamping force on the clip end is impressive. If all of the clamping power of the clip were to be applied to the legs, I'd think it'd crush them in. Are these things meant to grip the side of the chip carrier so the legs of the chip aren't bearing the full clamping force?

Stupid questions all, but I've never used or seen or even thought about these before and I'd rather know before I destroy a perfectly good chip.

No, because you need the last pin on the same side as 1 and the pin opposite of 1 if you're using it to measure power. You would be short 3 pins on one end or the other.
 
And I got my 2nd one in tonight with the same pin spacing issue. :(

Fortunately that's all I ordered because these are going into the trash.

BTW, I can't see what's in your picture even with max zoom.

you cant see the blue digital display thats reading "5.10" on the board?

Now that you pointed it out and I used the windows magnifier program, I can see it, yes. And now I understand what you were trying to say.

..........

So per my question above, how do these things not crush the pins they're clamping to? Is the main clamping force on the chip itself, not on the legs?

I've straightened legs from chips that I've removed from sockets and I can tell you that the force exerted by the SOIC clamps I bought would crush the legs of a DIP if all the clamping force was on the legs.

very little pressure is being put on the legs of the IC. You would have to squeeze one of these things closed with a pair of pliers for it to do any damage.

Okay. There must be something goofy with these SOIC clamps that I received or the clamping pressure must not be on the legs themselves somehow.
 
I'd gauge the clamping pressure on the ones that I bought in the "weak clothes pin" range. Like one you could put on your nose and it wouldnt even close your nostrils.

OK, that sounds good. I tried clamping the SOIC ones on the tip of my finger and I could stand it but it pinched *hard*.
