For PCB and plate made from the same material, the flex cut and non-flex cut will affect the typing sound and typing feel. Typing sound with flexcut PCB might not be as resonant as that none flexcut PCB, yet the typing feel of the flex-cut PCB could be gentler and smoother. If the typing feel is your primary concern, choose the flex-cut PCB, and if sound quality is your main concern, then a non-flexcut PCB might be more suitable. However, if you consider both, we suggest selecting a flex-cut PCB, and you can mod the PCB to enhance the typing sound.
Here are the differences in typing sound and typing feel for different plates.
PC Plate:
Typing Sound: PC material typically produces a soft, crisp sound with subtle resonance.
Typing Feel: PC keyboards generally offer a lighter feel, and the key presses might feel more lightweight yet slightly elastic.
POM Plate:
Typing Sound: Keyboards made from POM material might generate a pronounced "sliding" sound, often with a deep and stable tone.
Typing Feel: POM keyboards offer a relatively smooth feel, with a slight gliding sensation in key presses and a sense of stability.
Aluminum Plate:
Typing Sound: Aluminum keyboards can produce a clear, solid sound with potential metallic resonance.
Typing Feel: Aluminum keyboards generally offer a solid feel, and key presses might feel tight with a sense of stability.
FR4 Plate:
Typing Sound: Keyboards with FR4 material usually produce a mellow sound without significant resonance.
Typing Feel: FR4 keyboards typically provide a moderate feel, where key presses might have some elasticity, but the overall feel is balanced.
Please note that the descriptions provided are general in nature. Various factors, including keycaps, cutout designs, spring types, and more, influence actual sound and feel. The best choice depends on personal preferences, so if possible, it's recommended to try different keyboard materials to find the one that suits you best.
