Perf+: an improvement on perfboards and Veroboards
« on: February 27, 2015, 09:42:31 pm »
Here is an improvement on the age old stripboard or perfboard, it allows two dimensional connections with only small solder bridge connections, an kickstarter campaign will be up soon but I want to get your opinions first. Constructive criticism, bashing and disapproval allowed.

I am sorry, but I don't see that much improvement over normal perfboard with single pads or with strips.

I rather like it.  I would rather use that vs. the traditoinal (pad per hole) perf or (strip) vero boards. It is somewhat the best of both worlds.

I would prefer that the strips be centrally located between the holes. To make it less accidental that you would make a connection,
and also to allow connection from either side.

It allows you to route an connection between any two points while only using a small amount of solder
e.g. red = solder

I think it could be a good idea. Are the lines in the centre between the holes? It looks as if lines are almost touching holes. Also, if you are going in this direction, why not add small strip lines in perpendicular direction as well? (full vertical lines and dashed horizontal lines)

I don't like pad per hole boards because I need to add massive amounts of solder or add wire for connections, it gets messy. Strip lines are better because you can use strip lines as bus bars and easily cut out unneeded parts.

There are vertical lines in the back so you can just flip it over because the holes are plated through so it connects both sides. The lines are 8 mills(0.2mm) off the  holes, within tolerance to the fabs I'm using.

I've been working on something similar, still haven't got it just right. Wish you the best of luck!  :-+

You need to define the "value proposition" clearly and succinctly. I will spend 30 seconds determining whether to continue looking at your product.

The value proposition is "I suggest <X>. If you follow my suggestion, then you will get benefits <B>, will loose <L>, and <U> will remain unchanged".
There are lies, damned lies, statistics - and ADC/DAC specs.

Thanks for the tips, I'll keep that in mind when I am writing for the Kickstarter

I think it would require too much time-consuming board flipping to be practical.

I quite like the idea, but perhaps some shaping of the pads - maybe one side shaped to X-busses, and the other to Y busses...

Also some way to incorporate SMD pitched components on main board - or daughter 'conversion' boards with solder mask - so they can be dropped flush to the carrier 'buss' board.

My mind is racing, and I can see a few ways to make this work really nicely.
Image is just one part of the idea I'm suggesting... works top & bottom copper, with rotated 90-degrees for other side of the board as mentioned.
Don't ask a question if you aren't willing to listen to the answer.

I quite like your SMD component idea, although the pad shapes looks like the bottom should be rotated 180 degrees so there will be one rail per row of pads, here is my original pad design

Yes - in fact. I was suggesting both top & bottom 'extensions' (to meet either or both interleaved X busses...)
--- and identical (rotated 90 deg) on the other side of PCB to match the Y busses.
Extend the copper half-way - not just mask the solder mask - so solder bridges are easy and robust (no need to wick across to the curved edge of the ring).

Sorry quick scrappy sketch wasn't all that great.
SMD 'slices' would be really useful - and maybe other odd footprints.

I have LOTs of spare time, so can chat offline for a whole 'system' - which I reckon could have some legs...

Interesting idea, but IME the hard work with stripboard is not making solder bridges - hell, I get those for free! - but cutting the strips. These boards make neat connections, but you still need to cut the strips (and now on both sides). Some way of dealing with that would be really cool, IMO.

Another thought - running two (very thin) busses in each gap could be nice.
Combine them as a single buss if needed, or use independently for data or supply pins on either side... it needs a little more design with slightly smaller rings, and tiny lay-bys on the bus tracks (with solder mask between the buss lay-bys) to help with solderability...

+1

And after a few connections I think I would quickly lose track of what is connected to what.

I would put the bus strips into groups of 5 to minimize need for bridging and track cutting.

These are great prototyping PCB ideas.  It also seems like there needs to be an application for circuit layout to keep track of the "nodes" and parts placement.

I like the idea. But why not go for dual layer instead of double sided?
Much easier to keep track of your connections.

As a downside it will be more challenging to cut tracks.

Biting my tongue here, but you're supposed to use real wire on those perf boards not just smear solder across two pads.

I'd rather see two-sided normal perf board with round pads.

The problem with running two strips is that you need to separate them by at least the tolerance of the pcb fab, and have reasonable width for the tracks for current carrying capacity, so you quickly run out of the couple millimeters between the holes.

A few years back I saw this pcb that is the opposite of this idea - instead of make the tracks easy to cut they made it easy to make controlled solder bridges.  I kinda like the idea, but I've never tried it myself.

Nice lateral thinking...  X busses on one side, Y busses on the other

Not any more, he couldn't. It has been disclosed by publication.

OTOH nobody else could patent it and prevent him from making it himself.
