Green stripboard - what direction?!

Hi

I’ve just received my stripboards. See the picture below:

The problem is that I don’t know in which direction those pins are connected with each other.
In vero boards, for instance, there’s a clear indication in which way the pins are connected but as you can see on the photo, there are no hints apart from letters and numbers on the sides.
Can someone advise?

Thanks in advance!

Those don't appear to be connected at all. You can make your own connections with wires or blobs of solder.

But if you have any doubt, grab a multimeter and check for continuity between holes.

You wire to the individual pads with this type of board.

It is not strip board this is perf board. Short for perforations.

Awesome, that makes sense now. Thanks for all the answers. :)

@LarryD,

In that picture the pins are closer together than the pads and it looks like multiple pins are going to the same pads. Can you describe what's going on there? I'm interested in how that is put together.

That's an image I got from the net. Just an example of what someone has done using: http://www.newark.com/roadrunner/rrp-103/wiring-pencil/dp/07WX0910

I have done this years ago, not this neat though.

Looks to me some of the pins anchor the ICs. They may possibly be sitting on Kapton or the pads have been heat removed with an iron. The insulation on the wire disappears when soldering to the IC pins. .

Using a very fine tip and very fine solder!

Someone recently gave me a homemade Z80 computer, that looked just like that.

I use the Vero wiring system a lot in the early computer days:-

There were plastic combs to make the wiring a lot neater than that picture. Here is an example from one of my projects.

@Grumpy_Mike 100 combs for £22 is a good price!

I prefer wirewrap and Island of Holes perfboard, especially for developing. So much easier to make changes, fix wiring errors, etc. I like Velleman ESC1/2, 80x100mm cards, best quality for consistency of holes and copper. Pricier than generic stuff from where ever the cheap stuff comes from, but worth it.

When I was a poor college student, all I had was bare perfboard - had to epoxy sockets in place, then wire from there. Worked great for digital designs. Still does!
Can wirewrap to the legs of LEDs too - the black & white wires are the backs of LEDs layed out as large seven segment displays.

@Crossroads Good old days.

The only problem I had with wire wrap was the height of the final product. The Vero/Roadrunner method is lower profile. Etched PCBs are however the way.

Does anyone remember a method similar to Roadrunner where the wires were spot welded to the under side of the board? I cannot remember the name of the method.

Ok Google is great.
The method was called Stitch Wiring.
The US navy used it in torpedoes electronics.
Used nickel insulated wire, connections were spot welded.
The nickel wire was series resistive making each connection a terminator.
400MHz was easily managed.

Poor mans version is Vero/Roadrunner.

No look somewhere else for a better price.

Found some stuff on that high density wiring with enameled wire.

I'd have thought the lack of strips would have been a clue to the "stripboard" not being, well, stripboard.
