Disassembly

Given the hot-swappable nature of the switches and this being my first time with the HaiMu x AQIRYS Super Silent switches, it only made sense to take one of these apart. This is a linear switch with a pre-lubed stem and spring, and well lubed to where I don't expect to gain much from taking these apart for cleaning and re-lubing. It is also a silent switch in having a dampened bottom housing where the stem hits when bottoming out, but otherwise the switch design is quite similar to other such Cherry MX-style switches in that the stem pushes the copper contacts in the bottom housing together to initiate switch actuation that is read by the microcontroller on the keyboard.


Disassembly of the keyboard is not hard given the gasket mount doesn't usually rely on screws and yet the two-piece plastic construction means you need to use a thin, flat object to pry apart interlocking plastic tabs keeping the top and bottom panel together. As such, I do not recommend taking apart the keyboard unless you have a very good reason, since it is likely you will leave marks on the plastic or even potentially break off the tabs. Once it's loosened enough, the top case panel comes off easily whereas the plate/PCB section in the middle can be lifted from the bottom panel enough to access the two cabless going from the two separate batteries in the bottom panel. This is how AQIRYS has managed to put in a whopping 8000 mAh of combined battery capacity in the Libertas. Here we also get a better look at the shaped thick silicone sheet placed between the PCB and the case to dampen keystrokes and minimize any reverberations from occurring in the otherwise empty case.


At this point you can choose to remove all keycaps and switches to further separate the plate from the primary PCB itself, and this would allow you to also potentially replace and re-lube the stabilizers too. The PCB itself is the usual black in color although the lime green Kailh hot-swap switch sockets are an interesting choice. We also see the clear use of a gasket mount here with AQIRYS having added soft, thick silicone gaskets on the top and bottom case panels that the plate/PCB piece gets sandwiched into at various points all around the sides—this is one of the better implementations for a pre-built keyboard anyway. Powering the functionality of the PCB is a combination of two EVision VS12L17A and a VS11K34A microcontrollers; these are used in more budget-friendly keyboards but punch above their weight. I imagine one of these also does double duty as a 2.4 GHz/Bluetooth transceiver, but there isn't much info available to confirm as much. All the components, including the switch sockets, SMD LEDs, and capacitors, are soldered to a multi-layered PCB.

Before we move on, be advised that disassembly may void the warranty and that TechPowerUp is not liable for any damages incurred if you decide to go ahead and do so anyway.
