DC42 IR probe intermittent error
-
Would you like to return the sensor to me for repair?
-
I suspect it will be cheaper to just order a new one. I can try to solder it myself if it's a chance that it will work. Is it important how the sensor is aligned?
-
Yes, the alignment is important.
-
Ok guess I'm just going to order a new one then. Thanks for the reply.
-
I'd be happy to repair your old one for the cost of the postage.
-
Can I send both this one and the one I broke when I showed my screwdriver through the resistors (a old post you replied to)? Where should I send it? I can check what postage cost from my place and if it's not to bad I'll send them as a letter once I get my new one.
-
Sure, but I may not be able to mend the other one, it depends on the damage.

I did order a new sensor and was planning on doing a swap today. When I took out the old one I spotted a broken soldering on the sensor I had to push to get it working again. You can see it right below the cap in this picture. Soldered it up and it works good again giving consistant measurement and doesn't seem to drop out. As a feedback dc42 it would be smart with some more solder on this sensor as this would not have happend if it was thicker amount of thin on it like with the other SMD mounted parts.
The other sensor are missing a diode, a resistor and a cap if I'm not wrong all SMD mount. You can see a clear scratch where I pushed my screwdriver down so this is user error for sure but I was wondering if you had these components and could drop them in a envelope for me if the shipping isn't expensive ^^ I don't really need a third sensor but when I first got it it doesn't hurt to fix it up
-
There was a batch of IR sensors made several months ago which had faulty soldering on the phototransistor in a few instances, the same as in your photo. After that we added an extra visual inspection step to check that soldering.
Minim, send me a PM with your address and I'll put the LED and the resistor in the post to you. The capacitor isn't needed, we stopped fitting it on recent batches.

Ah all solved then
I'll throw on a blob of solder on the one I need to replace the resistor/led on also just as a safety measure. Both were bought at the same time.Thank you for that. PM sent. Is there any chance I could have damaged something else on the card if it was powered after those components where off? If you look closely it looks like the sensor is burned/brown on one of the ends if I compare it to the one I just soldered on. I can't recall if I tested it after I broke it during mounting.
-
I doubt that anything else has been damaged. The brown tinge is probably excess flux left over from touching up the soldering on the phototransistor by hand after the visual inspection I mentioned.
