Hardware Switch won't turn on

[Agilato]

After cleaning:
Mid 300= 300°C and half air speed?

Not bad at all for first time. Just do not stress it out.
Have fun with a project.

What temp you used to take off MT?

I think 350 half speed, will work well.

I lost the resistor in the top right corner. Can you tell me which one I have to order?

I removed the M92T36 with 420°C using a Yihua 8786D station, on 3/4 of its max. airspeed

You had to buy a book i advertised with resistors and capacitors.

Here is the nice topic we have:

How do I solder the capacitor? Using hot air or solder iron?

Make sure pads have solder on them place elements heat it up and surface tension will do the rest.

Should I remove the one on the left first?

Clean board from old flux.
Make sure elements aren't over tinned.
Place tiny layer of new flux and place elements on places.
On slow flow heat the place.
Its really works like a magic, even they will "magnet" to each-other you can use Tweezers to separate them.
Yes it's need some precision but you will get used to it.

Those capacitors are the same like the ones I ordered already, right?

Check topic i gave you earlier. All needed info is there.

 

[ds34]

According to the information you provided me they're "compatible", but I want to make sure that I understood it correctly.
However, thank you so much for your help. I will continue this tomorrow (it's 12:57 pm over here)

I'm unable to remove the flux even with 90% isopropyl alcohol...

You need good 99.9% it's game changer in flux cleaning especially.
I use cheap 99% for regular use such as cleaning and non important stuff.
For flux I use fancy one: MG Chemicals 824-1L 99.9% Isopropyl Alcohol Liquid Cleaner
Cleans flux in seconds, i was blown away how much better this thing is compare to regular IPA

 

[ds34]

I'm using MGChemicals 8341 and fake Amtech flux that I bought in a store (I already reported that to Amtech, and ordered genuine flux from their store)

Doesn't matter, i used 90% before... it does nothing to flux... spent hours to make boards clean.

How can I check if the chip is still usable?

 

[Agilato]

Check pins 5 and 6 if they have continuity to mid-ground pad, if any of this pins have - chip is dead. If you already ordered new one I would place new. Also at this stage check caps around BQ and P13USB

What do you mean by "Also on this stage"?
Btw: my genuine Amtech flux arrived

Now you don’t have MT with this short you might have others chips dead. Just check.

Can I use the resistor from the pdf file?

Do you mean that I might have killed other chips by removing the M92T36?
