Mylar Shielding

[Caius Filimon]

Hey everyone,

 

I was hoping I could get a little advice on the importance of Mylar Shielding in extremely thin laptops the likes of the 2018 HP Spectre x360 13 inch. 

 

I am interested in taking off the Mylar shielding paper on the motherboard so I can expose more of the back of the CPU (to get to the front of the CPU, the motherboard has to be flipped around so I can't be bothered). 

 

Do you believe that would have any negative effects on the laptop? The reason I want to take off the Mylar shielding on the back of the CPU slot is to add more thermal pads connecting it to the aluminium bottom cover of the laptop. I'm already using some thermal pads on a small surface area not covered by the shielding, and I've seen decent thermal gains given the tiny dual heatsinks of the laptop.

 

The Mylar shielding seems to be glued very strongly to the back of the CPU holder so I'd have to rip it apart, most likely. is the shielding terribly important? I suppose it's only really required to cover the rest of the motherboard, not the back of the CPU, surely?

 

Thank you very much for any advice you can give.

The likely reason why that's there is to prevent any solder points from touching the chassis. So if you're going to take it off, take off only what you need and no more.

Thank you very much for your help.

 

Would you be so kind so as to explain why it is that solder points should not touch the metal chassis? I'm very curious.

Anyone have any insight as to why? ^

They will cause the mobo to short circuit, essentially destroying your laptop. It's quite common in thin laptops since to achieve that title, they have to place the board really close to the chassis, hence why they then avoid shorting by putting mylar shields. That and also it's kind of good for not feeling the heat on your lap as much as you normally would?
