- In the previous video we designed our PCB and ordered some samples from pcbway.com. The PCBs have now arrived. Let's build a prototype and check if the pcb we designed works and is suitable for our requirements. While we are doing this we can practice some SMD soldering techniques
Part One of this project is here

Now there's a word I've not heard in decades "Heath Robertson" Gave me a wee smile to hear say that.
Yes, his illustrations still put a wide smile on my face. All those single-shot contraptions set in motion by cutting a wire...
Just drill that PCB and sink battery inside the hole. Put one connector on the other side - it can be just wire across the hole, supporting battery from the bottom.
Another wonderful, intriguing class. Thank you very much, stay well.
Heya, so almost ready love to see the end result
I would create a copper pad on the board under the battery, then solder a small piece of metal above the battery and bend it to press the battery down on the board as well as acting as the other battery terminal.
Nicely done. Try a Linx 1220 through-hole battery holder. Surface mount types always take up far too much space and put strain on pads. Solder paste lasts much longer in a fridge, but allow 24 hours at room temperature before using.
You could make a large pad on the board for the bottom of the battery, then use a strip of spring steel soldered to the other pad to hold the battery in place.
SOLDER PASTE - Can be revived with a couple of drips of Isopro and mixed with a cocktail stick
OK when I try with solder paste I will get some new stuff and also see if I can revive the old stuff. It will be interesting to do it on video. Thanks
an excelent project for any one repairing audio amps or radios because of the high harmonic content it will work at RF .
the only surgestion i have is to put a high voltage cap on the output to the probe as even some audio amps can have high voltages in them .
for battery i have used CR-2 mounted off board that will fit into a marker pen body.
Yeah I do agree about the capacitor on the output, it is only rated at 50V. I will try a CR2
I'm laughing out loud with the last questions answers🤣🤣
You should do a copper pour on both sides not only for power planes or screens. But it reduces the amount of copper needing to be removed and then recovered from the etching solution and means that it has a longer working life. Better for them and the environment.
Yeah I will continue with the pcb design videos and look at topics such as that. Thanks
fantastic PCB learning video :)
How about using an old E-cigarette as the probe. Cheap as chips 😀. Just epoxy an old probe tip in the center of the mouth piece. Keep the onboard battery and add a recharge circuit. Then you could add a mini usb socket to charge it. Probably need to redesign your pcb to be double sided though to shrink it down further. Would solve the battery issue.
As a professional PCB designer I still want to emphasize that manually routing your boards makes you understand more about electronics. Autorouter is always taking that chanche away to learn about routing and may cause unexpected problems to the functionality of your board.
" Real men don't use Autorouter's " 😂😁
@@andymouse Real men don't use apostrophes in wong places!
@@tommeier4659 I always get told off for that !
I will look at that in a later video
@@LearnElectronicsRepair Thanks, I appreciate that 😃
Interesting to see other peoples technique when SMD soldering, personally I could only manage 0603 with the microscope and as I don't have one the smallest I can solder (without a gun to my head !) is 0805 ! and yes a degree of ambidexterity soon comes with a bit of practice, in fact I would say the learning curve is surprisingly short. I do enjoy the challenge of designing an surface mount PCB but I still believe " Real Men don't use Autorouters " 🤣 and I have the tee shirt from my younger days (trying to be controversial) to prove it 😄...great tutorial...cheers.
My pet hate is very small smd components and enough room on the pcb to park a car on. Plus how many che k the power or voltage rating of 0402 resistors, also flowing the parts in a sea of flux, if the board and components are clean and oxide free their is enough flux in the solder.
@@TheEmbeddedHobbyist Yeah I have noticed a strong opinion on flux, good for you !😄
@@andymouse Strong the opinion is with this one. :-0
@@TheEmbeddedHobbyist LMFAO !
Should have used the PCBWay ryler Rich. Much more accurate than that old Tape measure. Is that a 1980s relic as well? 😂. Another great vid once again. 👍
"todesign" is not a word
You should not push down on a smd resistor or capacitors if one end is already soldered as you can break the metallisation away from the ceramic body and thus buggering the component now or later down the line with a tiny amount of vibration.
Love your videos, learned so mutch. Can you tell me from where to order de parts for repairs like mosfet en other(or some good webshops)?
Thanks in advance
I order almost everything from AliExpress
Lovely. Very relaxing to watch.
Where do you get those tweezers from?
Any news on the Huntron tracker PCB yet?
Thanks.
The tweezers are from ebay. I did some work with Detlef amend and Carlos from Retro Upgrade on the updated Huntron Tracker but so far it doesn't work. It's work in progress
Thanks Richard,
I just wanted to check the PCB wasn't imminent. I better just get on and do it Vero board!
Hi Richard, I found some battery sockets on ali and sent you the link on Discord as youtube does not like link here.
Hello would the BK-335-SM battery holder fit on the board? Really enjoying your delve into designing and build your own circuit, never realised how easy it is to create your own PCB.
Do you have a link for that one? I have found similar such as this listing but I don't think any of them are small enough for my purpose
www.aliexpress.com/item/4001226560199.html
Very nice. Could you show how you can use this? I understand you inject a signal, but what is this used for in trouble shooting a circuit and or board. Thanks
Yeah I will when i get chance. It is mostly used for audio and radio frequency circuit repair
@@LearnElectronicsRepair Thanks for taking the time to answer.
Nice job Richard. I wonder could you just solder a button cell directly to the board. Might be too dangerous though as they can explode easily. I'd definitely be wearing glasses if I was going to do it. Or run wires off the cell to the board.
@Mr Guru If you roughen both sides with course sandpaper first, you can get solder to stick. But yea you're right about it not wanting to stick. I just tried it with stranded mains wire and I got it to stick eventually using leaded solder of course. I don't think the lead free solder would be worth trying at all.
When I built the original prototype (this is how you do SMD on Veroboard!) I did exactly that and soldered wires to the button cell battery
ruclips.net/video/_aI6TLLVpDQ/видео.html
@@LearnElectronicsRepair Nice job on that Richard, I must of missed that vid. Personally I would choose this option again. Then you could just remove the bottom battery section of the pcb to gain more space. If you get Carlos to come back with your spot welder, even easier still 😉
Link dissapeared, digikey have retainer for 5.8mm battery but needs negative pad in the middle.
Smallest Battery holders I have used are for CR1220 I think too big...cheers.
CR1220 are available with spot-welded terminals. You can solder them straight to the board.
why not put some components on the back with vias?
I found a battrery cage/holder on digikey but my links keep getting removed.
I see you found that one too, my links from ther also gets removed 🥴
They are 12 mm wide😁
and first like! whoooo hooo!
I couldn't understand about 80% of what he said.
First!!!! haha
