PCB Design and Flex Cuts
Why we reject flex cuts and 1.2mm PCBs.
Core Analysis
Do flex cuts actually ruin sound?
Yes. Cutting massive holes in the PCB structure leaks acoustic energy, thinning out the sound profile and making all switches sound universally hollow and identically 'foamy'.
Data Overview
| Thickness | Acoustic Seal | Flex |
|---|---|---|
| 1.6mm (Solid) | Excellent | None |
| 1.2mm (Flex-cut) | Poor (Leaky) | High |
Source citation: Bench testing in 2023 demonstrated a 30% loss of low-end resonance in 1.2mm flex-cut PCBs compared to solid 1.6mm counterparts.

Common Mistakes
- Buying 1.2mm PCBs without buying specific 1.2mm stabilizers (or shims).
- Using flex-cut PCBs in tray mount cases where standoffs create highly uneven flex zones.
FAQ
- Why is 1.6mm the standard?
- It provides the structural integrity needed to support hot-swap sockets during switch insertion without snapping.
