Passo 7
Taking a peek beneath the motherboard, we make a couple cool observations. That massive copper heat pipe under the board is much beefier than the one in the S9—it looks more like the one we found in the Note9. Meanwhile, we peel off an additional, multi-layer piece of thermal interface material from the board. All that copper makes a great, big, flat surface, for better thermal transfer—but it's soft metal, so you need this soft interface to fill in any gaps that might otherwise kill performance or overheat your phone.

  • This thin sticker also seems to provide some RF shielding, as there's a big hole in the can lid underneath—where we find a PMIC and a big pink thermal pad.

  • TL;DR: We surmise that fast charging + reverse wireless charging puts some serious thermal stress on the electronics in this system. Samsung has pulled out all the stops to cool it off.

Quelques trucs cool nous attendent sous la carte mère.

Ce caloduc en cuivre massif semble bien plus costaud que celle du S9 et ressemble beaucoup à celle dénichée dans le Note9.

Entretemps, nous décollons une autre pièce multi-couches de matériel thermique de la carte. La grande surface en cuivre plate transfère très bien la chaleur, mais comme c'est un métal malléable, cette couche molle est nécessaire pour combler tous les espaces susceptibles d'empêcher le refroidissement et de causer la surchauffe de votre téléphone.

Ce fin autocollant semble également servir de blindage RF, car il y a un grand trou dans le dispositif en dessous – plus un CI de gestion d'alimentation et un gros bloc thermique rose.

TL;DR : nous supposons que la recharge rapide + sans fil inversée soumet l'électronique de cet appareil à de fortes sollicitations thermiques. Samsung a donc mis le paquet pour refroidir le tout.
