Hi,

Dos anyone what PCB drawing program there can be used for reading the gerber file to UniSolder 5.2 ?

Thanks !

I am shopping for a toroidal transformer.  Because they are expensive where I live, I want to make sure I purchase the best one possible.  It seems most on Digikey are center tapped (I think so, but do not know) so, is it better to get 12v parallel/24v series OR 24v series/48v parallel?  Or does it not matter?  I do not understand this so if someone can explain, and perhaps show wiring diagram, it would be very helpful.  All I know if sparkbg says 24v 120VA toroidal but there are many choices which confuse me.

Thank you!

P.S. I have spent quite a few hours soldering parts and have finished the back board, except for big parts but those are easy.  Now I just have to solder all the SMD caps and resistors on front board...there are very many!  I sure hope I didn't make any mistakes.

I'm using ZofzPCB, it's free (at least for now). It have an excellent 3D view with the ability of measurements in various modes and many other goodness.

I redrew the PCB tried to take into account remarks. Pls see attached models

Now it's better )

If you have to choose between those ones, 24V series connection is a better choice, because for a parallel connection windings have to be exactly the same, at best wounded by double wire, otherwise there be some loses due to windings non symmetry.
And bear in mind that winding connections (start/end) are matter. For series connection you have to connect end of one winding with the start of another, forming middle-point which should be isolated. Other two wires forms an output voltage.
If you don't know where the starts/ends of the windings, first of all determine wires of each winding - it should have near zero impedance. Then connect any two wires from different secondary windings and measure voltage on other two wires, if you get near 0v - just change wires of one winding.
For parallel connections it's basically opposite - start of two windings should be tied together, so as ends. After connecting two wires of different secondary windings, forming one output terminal, you should get 0v on other two wires, if so, tie this wires together and you'll get a second terminal. If not - again, change the wires of a single winding.

It's nice.
Evgeny1, I'm not sure but check U10 I see short between 13 and 14 pins.[/quote]

On page 47, there is this post.  In a later reply, sparkybg says it is okay. Must these pins be shorted together?

Look in the schematics. The answer is there waiting for you to discover. ;)

Just in curiosity tested eutectic Asahi Sn63Pb37 with C245945 - it changes phase exactly at transition 182-184°C. wow! :)

I am not so good at reading schematics but it looks like those 2 pins both are connected to 3.3v so it doesn't matter if they are bridged with solder?

Sparkybg,
Do you know how tall the push button switches need to be to fit the case you used?  I ordered some very short ones (not thinking) and they obviously will be too short.

I am using 13mm, and I still need to solder them a little bit upwards from the PCB, maybe around a millimeter or so. It is better to get the enclosure before soldering them, because the middle button and the side buttons are with different heights.

@Sparky - when you received your toroidal http://www.tme.eu/en/details/tst120w_24 ... tst120003/  did it include a mounting bracket?  If not, any suggestions where to get one or how you mounted it?  I didn't think about a bracket when I ordered it... = :/  I'll be mounting it flat in the case I will be using.

Thanks!

This came when I bought mine:
[attachment=0]ringkern-transformator-28v_300w[1].jpg[/attachment]

...but I bought it from a local dealer of INDEL, not from TME. I don't know if TME includes this.

Hi, as a rule the trancformer includes a bracket but if not, let me give you a trick you can use draining grill for sinks. You can buy it in any hardware store like OBI or any other one in your city.

It won't fit the 120VA INDEL transformer. The transformer's center hole is too small.

...but simple 1mm round cut sheet metal with hole for the bolt in the center along with same size rubber sheets on top and on bottom of transformer will do the trick without any problems. I've done it many times.

This Hirose socket is the exact match for JBC 245 handle - I think I have it on by BOM published here on page 63 at the bottom of the list.

Edit: here is the link from my BOM:

Puzzle,  doing a bit of research ran across https://www.eevblog.com/forum/projects/diy-jbc-nano/  seems the JBC nano handle/tweezers uses this... Binder 99-0996-102-05
www.farnell.com/datasheets/525884.pdf

Along with the HIROSE(HRS)  RPC1-12P-6S(73) could make a nice adapter cable for a nano handle, maybe even the tweezers?

The panel version: BINDER  09 0998 00 05

Will try it out when the orders all come together down the road.  I'm thinking a JBC T245 and a nano handle would make a great combo for the unisolder, guess would need an on off on toggle and a relay or two to switch back and forth.  Looking at the tip sizes available I'm not seeing any great advantage with the T210 vs T245.  Thoughts from anyone that has used the T245 and nano?  As far as I can tell the T210 uses the same Hirose plug/socket as T245

@ DinikS  -- now that is throwing in the kitchen sink !! :)
@ Sparky -- yes, should be easy to construct something similar.. thanks for the pic!
