International Crystal Manufacturing (ICM) manufactures a broad line of
custom precision crystals. Precision crystals are tight tolerance crystals
having a calibration tolerance of less than ±10 PPM and or a temperature
tolerance of less than ±10PPM or any other special processing requirements
such as ovenized crystals, low phase noise crystals, Quartz Microbalance
crystals (QCM), military crystals, BT-cut crystals, SC-cut crystals, IT-cut
crystals, and FC-cut crystals. ICM manufactures our precision crystals
using tight production controls based on our ISO 9001:2008 certification

Precision crystal product types
- any crystals made to operate at a temperature above the anticipated
ambient temperature (typically +50°C to +110°C) in order to
eliminate changes in frequency due to the change in temperature.
Low phase noise crystals
- crystals designed to have as pure a spectral signal as possible.
Quartz microbalance crystals
- are also referred to as QCM crystals which are piezoelectric quartz
crystals that utilize the Converse Piezoelectric Effect to determine
mass changes as a result of frequency change of the crystal.
Special cut crystals
- special cut crystals are those crystals that have been cut at a
different angle of orientation to enhance performance for specific
needs. Typical special cuts would include BT-cut crystals, SC-cut
crystals, IT-cut crystals, and FC-cut crystals.
- Military crystals
- quartz crystals that are designed to meet military specifications
(mil-spec) and produced to Mil-Spec requirements (QPL).
ICM custom high precison crystals typically have frequency ranges of
4 MHz to 180 MHz.
If your application requires higher frequencies for your precision crystal
applications, please contact our crystal engineers at 1-800-725-1426.
Precision crystals are often used in oscillators and filters that serve
as higher-end stable frequency references for personal communications
systems, telecom switching systems, medical equipment, cellular phones,
WAN/LAN equipment, test instrumentation, and satellite communications.
Features and benefits
ISO 9001:2008 certified ensures ICM customers always receive high
quality reducing costly returns and reinspection while keeping production
lines running as scheduled.
All ICM custom manufactured high end precison crystals are 100% inspected
on state of the art computer-controlled test equipment, not lot inspected,
to meet specifications before shipment ensuring customers receive
product that functions to required specifications every time ensuring
no production downtime, minimizing rework, and eliminating customer
returns due to component failure of ICM products.
U.S.-based complete automated, state of the art, manufacturing facility
providing faster request response, better customer service, and faster
Total control of all precision crystal production processes on custom-produced
products ensuring deliveries meet needed product specifications.
Family owned, on-site management, ensures customers can speak directly
to the ultimate decision maker resolving problems or providing solutions
No minimum order ensures customers can get exactly the quantities
of product they need reducing receiving, inspection, and testing costs
while also reducing inventory management costs.
On-shore automated manufacturing of precision crystals ensures quick
deliveries reducing inventory-carrying costs.
Ability to produce prototypes to orders of tens of thousands of units
ensuring customers get exactly what they want and reducing the number
of needed suppliers to one.
Have crystal engineers on staff to provide design, prototyping, and
pre-production support eliminating the need for multiple vendors and
associated paperwork costs by having a single source for specialized
precision crystal expertise.
