Can a microwave oven be used to reflow solder joint?

[tmhobadcap]

I heard somebody suggested a way of repair faulty led light bulb which I have never heard of. The way is to put the led light bulb inside a microwave oven and turn on the microwave oven for a few seconds. He said that faulty led light bulb is usually caused by poor solder joint between the led and the pcb. Putting the bulb inside the microwave oven for a few seconds will heat and reflow the solder joint making it works again.

Is that possible? I do not want to try this unless I have a spare microwave oven.

(I do not mean to suggest somebody to try this. It may be very dangerous. If you want to try, you are taking your own risk.)

In a word NO. The microwave energy will NOT heat the solder and any coils/ circles of wire will likely be destroyed.

Thank you!

Well, whoever that somebody is... take your broken LED light bulb and hit him/her on the head with it, then tell them you heard from someone else that this is an alternative way to fix a dead LED bulb too.

you can use an LED light bulb in a microwave

If you mean the lamp that lights the cavity, yes you can because it is outside the cavity and not exposed to the microwave energy.

yea i've seen some weird and shocking things in my life. this one definitely takes the cake as one of the most weird and shocking i've ever heard! eek indeed!

i thought the "rumor" somebody spread about fastcharging iphones with contactless charging in the microwave was better!!

The LEDs of the lamps are usually 30mA and inside they have 1, 2 or 3 LEDs, generating drops from 2.7v to almost 11v, I test them with a current limited laboratory source. Normally the LEDs burn out in those cases you can directly bypass and go

This thread needs to die, it's like a Biden commercial full of shit and worthless.

Microwave ovens do NOT like metal ... it's a great way to make a bunch of sparks and potentially ruin the element.

Now, a CONVENTIONAL oven could potentially reflow solder at the right temp. I had a 2007 Mac Pro video card stop working, and I stuck it in the gas oven at like 400 or 450 I think (might have been higher I can't remember) for 10 minutes (might have been longer), then took it out and let it cool and it worked fine after that. I can only assume there were some micro-fractures in a solder joint somewhere. The computer was about 9 years old when I did that.
