Part identity
Review brand, full ordering code, suffix, frequency and datasheet revision rather than relying on similar part names.
SUPPLY & QUALITY COMMUNICATION
Clear specifications, documents & delivery terms
Move procurement forward with actual part and supply information, and keep specifications, documents and differences clear.
Documentation by requirement
Request datasheets, material declarations, lot information or other documents at inquiry stage so scope and applicability can be confirmed.
Explicit delivery terms
Confirm quantity, minimum order, packaging and delivery. Supply status and quotations can change; agreed purchase documents govern.
A manufacturer certification or product declaration is not a certification of MERLIN and does not automatically cover every part. Review the issuing entity, product scope, revision and validity for projects with compliance requirements.
Alternatives need clear differences & validation.
We can help organize specification and sourcing information. Customers perform and confirm circuit compatibility, reliability and application validation against project requirements.

MANUFACTURING REFERENCE
From quartz wafer to finished crystal
Explore wafer processing, assembly and testing alongside product specifications.
01 / Quartz wafer process
Slicing → Coarse lapping → Angle inspection → Rounding → Fine lapping → Beveling → Etching → Frequency sorting
02 / Quartz crystal process
Cleaning, blank alignment, base plating, mounting and curing; SMD / DIP adjustment and sealing, followed by aging, leak tests, solder oven, final testing, laser marking and taping.
