Re: Really universal soldering controller Reply #1996 – October 30, 2018, 02:50:00 pm Can somebody link me to the gerber file for the optical sensor PCB? I am having a hard time finding it myself. Last Edit: January 01, 1970, 01:00:00 am by Guest
Re: Really universal soldering controller Reply #1997 – October 30, 2018, 04:38:03 pm The Gerber files for the optical sensor are part of the UniSolder52_gerber.rar on the first page of this thread (namely: unisolder_sensor.*). Last Edit: January 01, 1970, 01:00:00 am by Guest

Re: Really universal soldering controller Reply #1999 – October 30, 2018, 10:48:05 pm Ok folks, I messed up big time. I somehow managed to mistake the N channel mosfets for the P channel ones, and subsequently soldered them to Q2 and Q8... Worse though, when I removed them to correct the mistake, I ripped two pads right off the board.[attachment=0] I hope that the two copper rings (vias?) that are right next to the ripped pads are directly connected to them. I managed to solder the legs to those after scraping them to the bare copper. Did I just kill my power board or did I manage to save it?[attachment=1] Last Edit: January 01, 1970, 01:00:00 am by Guest
Re: Really universal soldering controller Reply #2000 – October 31, 2018, 01:49:12 am Those vias are connected to the pads indeed:[attachment=0]So in theory soldering the mosfets directly to the vias should work. Last Edit: January 01, 1970, 01:00:00 am by Guest
Re: Really universal soldering controller Reply #2001 – October 31, 2018, 05:26:44 am Hi, I don't know the type of thermocouple for the JBC C245, is a standard type or a manufacturer's specific? Thanks Last Edit: January 01, 1970, 01:00:00 am by Guest

Re: Really universal soldering controller Reply #2003 – November 01, 2018, 05:42:54 pm Thank you Morpheus1979!Removing the .txt solved the problem! I guess their parser just got confused on it threw it's hand in the air and didn't produce any meaningful errors. :D Last Edit: January 01, 1970, 01:00:00 am by Guest
Re: Really universal soldering controller Reply #2004 – November 01, 2018, 07:58:33 pm Did you just remove the TXT file? From the original archive!? If so, you should take a look at the preview of the pcb manufacturer then (if provided). Since the TXT contains all the holes that need to be drilled (for the vias, through hole components and the mounting screws), you may now have a pcb without any holes... which therefore (since there are no connections between the front and back layer) will not work!

Re: Really universal soldering controller Reply #2005 – November 02, 2018, 04:03:47 pm vulkan35, U10:7 and U10:8 are connected together, and there should be 3.3V-1.2V=2.1V (your diagram shows 1.989v and 3.26V respectively), but since you have somewhat right calibration current, I presume that is a bad measurement.About ID, remove the cartridge and connect handle to the controller, go to the calibration screen, ID there should be 24 5 (for T245). If it is not right, something wrong with ID resistors/line or R24. Last Edit: January 01, 1970, 01:00:00 am by Guest
Re: Really universal soldering controller Reply #2006 – November 02, 2018, 05:32:19 pm Maybe 3.3V bus is unstable, some ripple or what not. Or reference. All derived voltages tends to be on the lower side, of course it may be due to DMM error.So, the tool now is detected? Is it intermittent? Last Edit: January 01, 1970, 01:00:00 am by Guest
Re: Really universal soldering controller Reply #2007 – November 02, 2018, 05:57:19 pm [quote author="vulkan35"]Current between SENSEA + Vout1- = 335 ≈ 384µA swimsWhat can affect calibration?[/quote]I've checked on my boards and seems like in calibration mode the controller takes measurements periodically ([s:]in sync with zero crossing I suppose[/s:] constant measurement interrupted every ~180ms by tool detection for 20ms), and that's why current appears wandering.

Re: Really universal soldering controller Reply #2008 – November 02, 2018, 06:32:37 pm [quote author="vulkan35"]the current is floating constantly in any mode, it should be?[/quote]Yep, my board has the same behavior. Actually, calibration uses "no instrument" profile and interfered by tool detection algorithm. Last Edit: January 01, 1970, 01:00:00 am by Guest
Re: Really universal soldering controller Reply #2009 – November 02, 2018, 07:52:40 pm I can't get measurements from the boards, it all assembled into an enclosure.In what mode measurements are taken?For calibration:Offset for T245 and calibration should be zero, so U11 looks good. Gain of the diffamp section is x28 (ideal middle point of the trim pot), so, given 3.75mv drop on cal resistor, U15:5 should be around 105mV, so your measurements are close. U17:6 with 52.5mV (x0.5 gain by U15) input should be around 1.5V (U17 gain is x29). Don't take it as a reference, I may be wrong. Last Edit: January 01, 1970, 01:00:00 am by Guest
