content: Perf+ 2 is a revolutionary electronic prototyping board designed for ease of use and flexibility. No jumper wires required!https://www.crowdsupply.com/ben-wang/perf-2It is a new version of my previous project Perf+, with larger holes for compatibility with more packages, solder mask between the bridgeable sections to make soldering easier and design optimised for more surface mount packages.*I am the creator of this project

content: Looks kinda nice, maybe a little bit small with only 6x9cm in size. But I think I'll sign up for a 5 or 10-pack and see for myself if they are compatible with my projects and normal usage style...

content: Cool project! Unfortunately the exchange rates are a bit unfavorable for me at the moment making it a bit expensive. I see you surpassed your goal anyways, so all the best! Hope I can get some boards one day in the future.

It is quite amazing how the china export destroys so many start-ups.But I really like the board too, only concern is the small spacing between the hole and the bus line. I would believe it’s quite hard to unbridge it, if you bridge it by accident.

content: Quote from: Rager on March 01, 2016, 03:13:52 pmI agree, seems like a great idea, but I'm wondering how easy it would be to accidentally bridge to the bus line while soldering your components in place?If it turns out to be quite difficult to have this accidentally happen, then I'm in for 5 boards

content: Having made my own perpendicular double-sided protoboard, I have to say this is a much better idea on paper than in practice. But for those who can't make their own PCB, it's worth it if you want to spend lots and lots of time making one board that you will never want to modify or make again.I personally only bothered doing it once. And it was cool. I had a complete circuit with no jumper wires, at all. But this method of making a board is very difficult to design and debug, which hopefully is solved by the software. The first time I decided I wanted to add this or that to my circuit, I looked at it and it was just not worth bothering with. The mental gymnastics were too much. For me, protoboard is for a circuit in progress to be easily modified and messed with. PCB, thereafter.This board is still going to be supercool using it single-sided, just for the fact of the bridgeable bus strips. I think it will be useful, either way.

content: Quote from: broz on March 01, 2016, 05:29:55 pmIn my experience with the board, I found it almost impossible to accidentally cause a bridge, as you need to put tremendous amounts of solder to overcome the surface tension.

content: It says compatible with "most surface mount packages", but it looks like anything smaller than SOIC will not work. Am I missing something? In my experience, most surface mount packages are smaller than soic, usually QFP, TSSOP, QFN or one of the various BGA types.

content: Quote from: jeremy on March 03, 2016, 07:54:14 amHow would even SOIC work? They use 50mil pitch (1.27mm) so unless you bend every other pin up and connect those pins by flywires they can't be used on any normal thru hole pcb....

content: Quote from: matseng on March 03, 2016, 08:16:58 amSorry for being misleading, it is meant to be compatible with small pin count SMD packages such as resistors, capacitors, LEDs, voltage regulators and 2P SMD switches.100mil pitch packages *should* work but have not been tested.
