An electronics technician stars in a video showing an intricate repair of a Razer gaming laptop motherboard by hand. This is one of the most challenging PCB repair tasks we have seen come to a successful conclusion. The repair fixes damage that appears to be the result of the same underlying issue outlined by another repair tech, who asserts that Razer’s Blade 14 mobo has “a fatal design flaw.”
It is definitely worth spending two minutes and 48 seconds watching this, even if you watch it at 2x speed, but you then need to remember to pick up your jaw from the floor.

Being adept at electronics repair is an enviable skill. Moreover, as components are continuously miniaturized, such highly skilled work pushes the bounds of human-level ability. In the above video, we see an unnamed technician work on a severely damaged Razer laptop motherboard.
The video begins with a close-up of the laptop motherboard, showing a chunk of its structure around a screw hole that is obviously missing. We'll discuss the potential causes of this damage later...
As a first step, the technician uses a grinding pen and takes away material at an angle. This work provides improved access to the multiple conductive layers of the PCB, enabling them to be addressed separately during upcoming soldering repairs. Think of this task a little like how ancient rice farmers would terrace the side of a mountain to provide workable paddy fields.
Pausing the video, we can see the deft grinding pen work makes more than 10 PCB layers distinguishable. Once they are happy with the layer exposure, the technician moves to the intricate cleaning of circuit traces at the chosen level to prepare them for reconnecting using hair-thin enameled wiring.

The technician deftly solders the first target PCB layer with their iron and ultra-thin connecting wires. With the first of several layers now considered fixed, solder mask is applied to insulate and add structure where it is currently missing. This meticulous work was repeated across several layers, restoring the damaged PCB both electrically and structurally.
