        Hello I was looking for small PSoC development board to order, but couldn't find any. If anyone knows smaller PSoC board then PSoC 3 starter kit I'd really appreciate the help. That's the reason that I decided to collect my own PCB from PSoC components. I'm thinking to order CY8C3866AXI-040 component, but I noticed that the pins are very close to each other and it's impossible to collect manually. Is it possible to order components which pins are far from each other and would be possible to collect manually? I'm just starting and would really appreciate if someone could help me where to look for all the components? Thanks in advance

        Hi Gurgen, You said "CY8C3866AXI-040", Which has 100pins TQFP package. Between pins is 0.5mm, It's rather wide than MLF package. It can soldering by hand with carefully. As you know, SSOP pakage is more wide, 1.27mm. PVI-021 and PVI-070 has SSOP package. Would you chose this device?

You are here in the Software - forum but your request smells a bit like hardware, isn't it?

   

Until now, only PSoC1 devices come in DIL-package, preferrably the CY8C29466-pxsomething. There is a development kit for PSoC1 costing $40. The disadvantages using PSoC1 compared to PSoC3/4/5 are:

   

Only 8-bit CPU
Few registers
slow execution
No intrinsic debug-capabilities (or you have to by an ICE-Cube)

   

There are already PSoC boards in the Kit-store the cheapest is the PSoC4 Pioneer kit which even costs less than the PSoC1 kit, It is programmable to your needs and you can debug your programs with breakpoints, variable inspection etc.

   

Have a look at the kits here: http://www.cypress.com/?id=2218&source=header

   

and here: http://www.cypress.com/?id=4749

If you google "youtube surface mount soldering" you will get

   

a number of hits on hand soldering.

   

 

   

In my experience most important tool in shop is a large 5 - 10X magnifying

   

optic you can use while working on fine pitch packages.

        TQFP is not easy for soldier but it is doable, we made our own samples and sometimes need to replace chips ourself. However, there are some ready made boards as suggest.

        My fault, 0.635mm for SSOP pitch.

I recently soldered a 100 pin TSOP package (0.5mm pitch) by hand - took only 5 minutes or so. You basically need only good flux and some solder wick...

I found that you can use a "USED" solder wick to do the soldering.

   

With a lot of flux, place the solder wick on the top of the pins and use a soldering iron on the top of the solder wick, the solder on the wick will transfer to the pins and the board.

   

I am still pratising and trying with different USED solder wick. (You need to fix the location of the chip to the PCB by solder the corners first)

I have seen videos using a toaster oven and solder paste to reflow a part.

I even saw a "Soldering Station" built of a kitchen-cooktop (regulated) and a frying-pan with a lid. What really did astonish me was that it DID work. I admitt the regulator was a rather large one and far off my capabilities of designing a 1.5kW closed-loop regulator.

A friend of mine used a electric fry pan to do the soldering. The surface of the pan needs to be flat.
The PCB however seems a little bit twisted after the soldering. It is faster then solder by hand.

        Flying pan is difficult to control the temperature. It usually use to melt many chips and collect those. I recommend you of Hot-plate.

Using a "Flying Pan" can be very difficult to handle, try it with sitting on a flying carpet .

Looks like it is better to redesign the controller with PSoC.. PSoC rocks......

Yes, when soldering, keep cool.

 Keep cool, use HOT iron for soldering   😄

   

Let's back to the topic. 

   

For DIP package. you may need to use PSoC1. The TQFP, it is doable, just need patient and practice.

        Seriously, Hot air brower and cream solder paste is handy. I can work with it for MLF package likes a 27894. ( I can drag under-right corner 🙂

PSOC4s come in easy to solder QFPs, they are available to order on the cypress store and on distriutors. There will also be devices in SSOP and other packages but they are not available yet.

   

Hot air is great, but I prefer using a good temperature controlled solder iron and folder flux. The Hakkos are cheap and have good quality. Flux is extremelly important when soldering.

   

 

   

If you are not confortable soldering and designning your own board. I would recomend getting the FREESOC mini. it is really small with a psoc5 and programmer in it. Also the Schmart boards are good.

   

Finally the Pionner kit s the most economical way to start with psocs, but it only sports a PSOC4.

Thank you very much this was really helpfull.

   

I though about all suggestions.

   

I'm thinking to choose EzPSoC (http://kmmankad.blogspot.de/2012/12/psoc35-hardware-options.html) done by Zeta.

   

As I understand I can programm it with miniprog3 and also has USB communication. There is also nice schematic which I can use.

   

Thanks Zeta for that.

You're welcome. But the EzPSoC3 was designed and build by kmmankad.

   

he was actually the first one to post an open source board design for a PSoC3 device. With his design just make sure you use a older mask as otherwise the USBlines will short with the USB connector case.

the other day the guy was posting links to his aliexpress page, maybe we should let aliexpress know the guy is posting his unwanted links here, they might not be happy to hear that.
