SEAM-Sealed Package Design for kHz Crystal Reliability

Hermetic sealing

Seam welding creates a metal-to-metal seal that blocks moisture and contamination, protecting the tuning-fork blank for decades.

Thermal performance

The robust package withstands reflow and thermal cycling without compromising seal integrity or frequency.

Mechanical strength

Seam-sealed packages resist mechanical stress and vibration better than plastic alternatives, suiting industrial and automotive duty.

Frequency Stability and Circuit Matching for Sealed kHz Crystals

Frequency tolerance

Hermetic sealing preserves tight tolerance, keeping the 32.768 kHz output accurate over temperature and time.

Load matching

Match CL and ESR to the RTC oscillator so the sealed crystal starts reliably and keeps time precisely.

Aging

The hermetic environment slows aging, keeping long-term drift low for battery-backed clocks and meters.
