Gasket Mount vs Tray Mount Keyboards: What's the Difference and Why It Matters
When you start exploring the world of custom mechanical keyboards, you quickly realize that the switch type and keycap material are only part of the equation. The mounting style — how the internal plate and PCB assembly is secured inside the keyboard case — has an enormous impact on how the keyboard sounds and feels. The two most common mounting styles you will encounter are tray mount and gasket mount. Understanding the difference is essential to making an informed purchase.
What is a Tray Mount Keyboard?
Tray mount is the traditional, most common keyboard mounting style. In a tray mount design, the PCB (the circuit board) is screwed directly into standoffs that rise from the bottom case of the keyboard. The plate — the metal or polycarbonate layer that holds the switches — is then attached to the PCB. The entire assembly is rigidly connected to the case.
This design is cost-effective to manufacture, which is why it dominates the budget and mid-range keyboard market. However, the rigid connection between the PCB and the case creates several acoustic and tactile drawbacks. Because the mounting points are distributed unevenly across the board, different areas of the keyboard can feel and sound noticeably different. Keys near a mounting point feel stiffer and sound sharper. Keys between mounting points have slightly more flex and a different acoustic character. This inconsistency is often described as "hotspots" by enthusiasts.
What is a Gasket Mount Keyboard?
Gasket mount is the premium alternative. In a gasket mount design, the plate and PCB assembly is not screwed directly to the case. Instead, it is sandwiched between the top and bottom halves of the case using pieces of rubber or silicone — the gaskets. These gaskets act as shock absorbers, isolating the internal assembly from the rigid case.
The Odin Gaming Aurora65 uses a full gasket mount system. The result is a keyboard that feels dramatically different from anything in the tray mount category. The entire typing surface has a uniform, cushioned feel — there are no hotspots because the assembly floats freely within the case. When you press a key, the flex is consistent whether you are typing in the center of the board or at the corners.
The Acoustic Difference
The acoustic difference between tray mount and gasket mount is significant and immediately noticeable. Tray mount keyboards tend to produce a sharper, higher-pitched sound with a metallic ping that resonates through the rigid case. This is the sound that gives many budget keyboards their characteristic "clacky" or "pingy" character.
Gasket mount keyboards, by contrast, produce a deeper, more resonant sound that enthusiasts describe as a "thock." Because the internal assembly is isolated from the case, the sound energy is absorbed by the gaskets rather than transmitted directly into the case walls. The result is a fuller, more premium-sounding keystroke that is significantly more pleasant for both the typist and anyone nearby.
The Typing Feel Difference
Beyond acoustics, the typing feel of a gasket mount keyboard is fundamentally different. The slight flex of the gaskets creates what is often described as a "bouncy" or "springy" feel — each keystroke has a subtle give that makes extended typing sessions noticeably more comfortable. This is particularly valuable for gamers who spend hours at the keyboard, as the reduced impact on the fingers and wrists can help prevent fatigue and repetitive strain.
Tray mount keyboards, being rigidly mounted, transmit the full impact of each keystroke directly through the case to the desk. Over long sessions, this can contribute to finger fatigue, particularly when using heavier tactile or clicky switches.
The Aurora65: Gasket Mount for Gamers
The Aurora65 was designed from the ground up as a gasket mount keyboard built for gaming. It features a 65% layout — the optimal size for gaming, eliminating the numpad and function row while retaining dedicated arrow keys and a cluster of navigation keys. This compact layout keeps your mouse hand closer to the keyboard, reducing shoulder strain during long gaming sessions.
The Aurora65 is also hot-swap capable, meaning you can change switches without soldering. This allows you to experiment with different switch types — from light linear switches for gaming to heavier tactile switches for typing — without purchasing a new keyboard. Combined with the gasket mount system, the Aurora65 represents the pinnacle of what a gaming keyboard can be.
Which Mounting Style Should You Choose?
If you are buying a keyboard purely based on price and have no strong preference for acoustics or typing feel, a tray mount keyboard is a perfectly functional choice. However, if you spend significant time at your keyboard — whether gaming, working, or both — the gasket mount experience is genuinely transformative. Once you type on a quality gasket mount board, it is very difficult to go back. The Aurora65 is the ideal entry point into this category, offering premium gasket mount construction at an accessible price point.
