Uyue 946c Phone Repair / SMD Reflow Hot Plate Review and Upgrade 

Good idea, that could be a good mod. Lots of room for an Arduino etc.

@@NearFarMedia You get some pretty good multipoint PID controllers in that standard 48x48 industrial format, and then you just have to either program in a temperature profile, or just change to the preset profiles as needed. Often they are USB programmable as well these days, meaning you can have a PC do the work for you.

Apparently you can switch the heating output off and on by holding down the Up-Key (most right at mine).

Ooh, measured on the exposed metal of the hotplate itself? Ouch. If you fixed it, good gob! They do work well after a couple mods like I showed. I still use mine from time to time.

@@NearFarMedia Yes, directly on the soldering surface of the hotplate. I first recognized it during rework due to a prickling on my arm. Then I took my multimeter and found that there is AC with respect to GND. I think I had a defective device from production, because the company logo was removed. It was only 40EUR or so all incl. I came here to see if the fault was a design or production issue. Something learned again, thanks to you.

Did you check the video description?

Hi, here's a link to the exact listing I purchased mine from. :) www.aliexpress.com/item/33016355254.html

I have added links to the manuals in the video description. I hope it helps. :) Some of the controllers have a cut down feature set depending on what the manufacturer decided to include so your mileage may vary depending on which specific controller you got.

That's great. Thanks. I did find those guides but I think I got a Rex knock-off version as the parameter labels did not match. I will take a second look though and I'll see if I can line them up so to speak!

Your board needs to be 185c then use hot air to break free.

As stated in the video........ it is nichrome wire wrapped around a mica former.

It's made from aluminium, around 5-6mm thick I think from memory.

Yep, I still have it and it works great. 🙂

@@NearFarMedia many thanks for you're reply

It's just normal fiberglass matting.

@@NearFarMedia thank you… I’ve bought it and was worrying. Now I can restart to Breath

You might be able to do it by rewiring the two elements from parallel to series connection.

This one is 200mm x 200mm square. It might work on 230V if you connect the heater elements in series instead of parallel, but you'd have to make sure the temperature controller is rated to 230V too.

@NFM Thankyou for replying back, my electrical knowledge is basic so maybe I will have purchase a heat plate from the United Kingdom, I was hoping to purchase one from from China because possibly they might be cheaper because times are difficult in the United Kingdom and Europe at the moment. Great video thankyou.

There's no need for ceramic heaters in this application, and the 6mm plate spreads the heat evenly enough so a thicker plate will only add thermal mass and cause it to take longer to cool down. The steel for the case is much thicker than a PC PSU case, it's physically larger too. The controller may be cheap, but here you are paying for a completed product, not a few loose parts. It might, maybe work out cheaper to DIY, but certainly not when you factor in your own labour costs to build something.

@@NearFarMedia Nobody factors in own labour cost as nobody is that busy.

@@juliusvalentinas I guess you speak for everyone and how import their time is... what an asinine comment to make.
