Oh, if you think this cable of the heat-plate is kind of dodgy, wait for a video which I planned to do soon. The one I bought screams "I'll kill you" when you just look at it :) Though, I have to admit, it did the job which I needed it for. Anyhow, nice insights. Thanks!

@Tony359_2 19 күн бұрын

Oh yes, I was expecting something MUCH more dangerous. There is a proper SMPS inside with some separation. I was expecting 220V dropped to 12V with a resistor :D Looking forward to watching the killing machine video! :D

You can put a pcb in a bag with solvent/cleaner and then stick it in an ultrasonic full of water. You use less cleaner that way and the junk that comes off stays in the bag.

Hi Tony! Reflow soldering is only done with SMD stencil. Any PCB manufacturer will have an SMD stencil option, it must be used for solder paste, it makes sure that a precise solder paste quantity is used on each pad. You do not have to waste too much time for precise component positioning, the solder once melted will center them quite nicely. It takes some practice to perfect this method but once it is done, the results are quite spectacular. PS: Still, in my view, reflow soldering is no fun, at least for me anyway. I feel i have done nothing unless is solder each component by myself, and i love doing it all day long, especially for small SMD components 😅 I have done one such video, showing my way of soldering...

@Tony359_2 18 күн бұрын

Yes, PCBWay actually mentioned that after I sent them the video! :) There is an option when you order the PCBs. I still like the screwdriver method! :D

Great video Tony! I think the trick to getting a smooth result with solder paste and a hot plate is a stencil. I’ve seen people use them elsewhere-I think you could scan the PCB, trace the solder pads, & send it out to be laser cut. You could get one laser cut out of thin plastic & then apply a thin film of paste with a squeegee. Never done it before-but I think it’s the trick to getting the proper amount of paste so as to limit or eliminate solder balls and bridges. If you try this-show us! I’d love to see the process in action. I’ve only seen snippets of the procedure.

@Tony359_2 22 сағат бұрын

Indeed - PCBWay sent me a message on that subject: stencils can be ordered along with the PCB, it’s an option on the order page, I had no idea. Much funnier to use a screwdriver though 😂

As a re-tiered electrician. I can confirm the fuse should always be in the live conductor and not the neutral. And agree with @piotrokrutny477 stated below the metal plate could become live under fault conditions leaving it at 240volts.

Hi Tony, great job. I really like watching your videos. I repair various electronics myself, especially old motherboards, etc. In my opinion, you should reverse the polarity of the mains power cables. The Blue wire should be Neutral and the Brown wire should be Live. It will be safer if the phase passes through a fuse. If you have connected the phase as in the video, and a failure occurs, blowing the fuse will not cut off the phase from the device. The phase may still be on the hot-plate. Best wishes

@Tony359_2 19 күн бұрын

Very interesting thanks. I followed the "N" and "L" on the SMPS legs. I didn't realise it ended up with the Neutral going on the fuse. Your point is solid. Do you think it might upset the SMPS? I doubt it as the plug it came is non-poiarised. Thanks for spotting that!

@cs233 19 күн бұрын

Not to be too picky, but you should always use ring style terminals, not the U shaped ones, for safety grounds. It prevents the ground from coming completely disconnected if the screw loosens a bit. I believe it is even a requirement of safety certifying agencies like UL, CSA, etc. Not something g that would be easy to add after the fact, but it would also be nice if the top of the plate had at least been silk screened with a large “HOT” label. If they can manage to put their logo on it, you’d think the warning would be pretty easy. You could probably do it after the fact with a 3D printed stencil and some high temperature engine paint if you really wanted to. I’m working on some projects that will need assembly of SMD parts and am looking at hot air stations and hot plates. Don’t think I’ll get this one - plus need 120V).

19:08 reminds me of the xbox one x power supplies where the primary side cap is covering some IC's that get extremely hot and cook the cap. Let alone theres no ventilation even if you get the type of supply that doesn't have the IC's under the cap. The one I replaced the cap on didn't have the IC's under it. That hot plate is neat. Might pick one up if the price is right. Thanks Tony.

@@Tony359_2 Right. Well how else would you buy the next new thing? Like a laptop I got recently. Battery is dead. 4 cell battery. One cell died, the other 3 are fine. Guess I just need to make a few 3200mAh battery banks now and buy a new one. Instead of the BMS just locking me out, some diagnostics would of been great. Without buying a $600 bit of equipment. Literally color coded holes corresponding to each cells +/- strips would suffice. Marks on where to safely cut so you can extract and change the cell.. Thousands of shops probably PAY to dispose of them, when they're repairable/still good. Designed poorly.

They do! I didn't know, they let me know after watching the video LOL! Components can withstand temperatures up to 170C I think no problem - more and you need to be quick. Pre-heating for soldering is only up to 100/120C so that is totally fine even for capacitors! Thanks for watching!

That low 5 volt rail screams poor capacitors to me, the way it changes with load and where on the circuit you measure it. Also, when you were trying to remove bridges from the your newly made BlueSCSI board try a soldering iron bit with some flat face on it, flat surface will create an area of higher surface tension for a solder blob to form on the bit and off the pcb.

@Tony359_2 18 күн бұрын

Thanks! My other flat tips are too big, I should buy a T210 knife bit, thanks for the suggestion! The PSU on those old Mac's are not great - though that is a Sony PSU in a can. I only then remembered that I need to replace the socket of the ADB chip on that Mac - I replaced the chip (the cool repair video is on the main channel kzfaq.info/get/bejne/qc-CYLt2zcuxaWQ.html) and someone recommended the "turned" or "machined" sockets for better results. They were wrong! I should install a regular socket there asap! :)

xt30's are rated to 30 amps of dc current, at 500V. so while not technically mains rated, ~240 at what, an amp? maybe 2 at most? i can't imagine its that bad, aside from the obvious concern. questionable, but i've seen infinitely worse.

Oh absolutely. It's just that there is already a perfect standard for that - in the UK we call it "figure of 8" :) I was 100% not concerned about the ability of the connector to carry 220V and the current needed for the plate - my concern is that it comes off and shocks me :) Thanks for watching!

Ok, couldn’t help myself not making a second comment. If you do decide to get an ultrasonic cleaner sometime and are worried about things like the little solder balks accumulating in the cleaning solution, just get some paint filters online or any hardware or paint store or even coffee filters and a stainless funnel that they will fit in and occasionally pour the solution through a filter to remove any accumulated particles. If you really want to be picky, order some laboratory chemical filter papers instead which will generally be even finer.

Your hot plate unit looks substantially more dodgy in all the little nooks and details than the one I got for hardly more money. The plug isn't centered in the moulding, whereas mine is perfectly centered! I cut my power lead short and replaced part of it with a copper one. The copper clad aluminium conductors in the original cable are fine and safe like they are, but I have a zero tolerance on copper clad wiring in my shop to eliminate the chance of confusion.
