Summary

NEW MODEL NOW AVAILABLE:

"PCB Workstation with Needle Probes" (JUST RELEASED!)
http://www.thingiverse.com/thing:2318886

"PCB Workstation with Crane Arms" is an evolution of my original project "PCB Workstation with Articulated Arms" (http://www.thingiverse.com/thing:801279).

Each crane arm can be easly positioned to make precise electrical connections in very small points of a printed circuit board.

This tool uses the Hirschmann spring loaded needle point test probes
(http://it.rs-online.com/mobile/p/sonde-ad-ago/0775726/).

The base of the "PCB Workstation with Crane Arms" can be equipped with the articulated arms and custom accessories available for the original project "PCB Workstation with Articulated Arms" (http://www.thingiverse.com/thing:801279/#files).

Post-Printing

Step 1: Mount the silicone bumpers

I suggest to apply 5 silicone bumpers beneath the base piece, so it will be more stable on the desk. You can use bumpers with a diameter up to 20mm.

Step 2: Assemble the PCB holders

The central part of the base consists of 4 sliding pieces arranged in a cross along which can be moved the anchoring blocks to firmly keep the printed circuit board in place. The assembly of the PCB holders to the base piece requires some wing nuts (5mm) and Hex bolts (5×12 mm). The PCB holders have two faces, one for straight sides, the other for the corners of a printed circuit board. You can choose the right face simply turning the holder.

Step 3: Assemble the crane arms

Fit the vertical crane arm into the hole of the rotating base support, then mount the horizontal crane arm using a wing nut (5mm) and a Hex bolt (5×12 mm).

Step 4: Install micro sprung probes

The horizontal crane arm ends with a clamp to fit a micro sprung probe
(http://uk.rs-online.com/web/p/needle-point-probes/0775726).

Step 5: Add optional parts

Now that you have almost finished your customized "PCB Workstation" perhaps you would like to add a magnifying glass, or a LED lamp, or even other accessories available from my original project "PCB Workstation with Articulated Arms" (http://www.thingiverse.com/thing:801279).

Very cool update. Printing my 2nd set of supports now!

Did you change the hole sizes in the base? The Base_support seems loose in a version of the previous base that I already had printed.

Hello James, the hole size in the base has not changed, anyway I have designed the base_support with a slightly smaller diameter so that is can rotate easier without using too much force on it.

Makes sense. I think it is better to be slightly smaller. I've added some masking tape to increase the resistance slightly while still being able to twist easily. I am really liking this arm update. MUCH easier to print! Thank you so much. Great Job, as usual.

it look great but it is missing motors, arm board, solderer ... (electrobot)
is it made with openscad ?
i will print it thanks

Hello Christophe, I was just thinking about adding stepper motors to the crane arms but it requires a lot of expensive extra parts, anyway it might be a future project...
This tool has been designed with MoI 3D software (www.moi3d.com).
I look forward to see your print of this tool ;-)

hi giufini ;)
my only one working 3d printer, for now (wanhao i3 duplicator) don't work yet :(
as i' m handicapped i will try your tool to see what i need more to properly learn and make electronic ...

is not very expensive and it should be enough to start a very good electrobot
if you can switch to openscad for it (the only 3d cad free open-source and usable without mouse( cool for peoples that can't really use a mouse)) it should help a lot of peoples
if you need help on electrobot just tell me ;)

This one looks much usable than previous version. I'm goind to print it. Thank you for this design.

What an immensely clever device !
