AXTAL CONSULTING Services

AXTAL CONSULTING is an independent test house for Frequency Control Products.
The company is privately owned by Bernd Neubig, a Physicist and Electronics enigneer with more than 40 years experience in the quartz crystal industry.
AXTAL CONSULTING's laboratory facility is located in Mosbach/South-West Germany
.
It offers a broad range of services in the field of quartz crystal units, resonators, crystal oscillators, and crystal filters, some of them listed below:

 

  • Failure Analysis of Crystals and its Oscillator Circuit. Determination of the required corrective actions

    The most frequent causes of crystal failures are
    ► Insufficient safety margin ("oscillation allowance") of the oscillator stage for oscillation start-up
    ► Strong Drive Level Dependance ("DLD") of the crystals's resonance resistance
    ► Too low or excessive crystal drive level (crystal current or power)
    ► Frequency jumps (discontinuities) or stopping of oscillation in a certain temperature range due to so-called "Activity Dips" of "Frequency Dips" of the crystal
    ► Mismatch between the specified crystal load capacitance and the effective load conditions given by the oscillator circuit

     
  • Optimization of the crystal application to assure high operational reliability

    ► Support in the design of the circuit of on-chip and discrete oscillators
    ► Worst-Case Analysis of the safety factor of oscillation start-up
    ► Testing of the crystals for Drive Level Dependency (DLD) and Activity Dips
    ► Measurement of crystal drive level in the circuit
    ► Determination of the working frequency and the equivalent load capacitance of the oscillator circuit
    ► Proposal for modification of the oscillator circuit in case of issue shown in above points
    ► Support in modification or setting up an appropriate crystal specification

     
  • Testing of Quartz Crystals, ceramic resonators, Oscillators, SAW devices and Filter

    ► Electrical testing of crystals and resonators according to IEC 60122, IEC 60444 and MIL-PRF-3098
    ► Electrical testing of oscillators according to IEC 60679 and MIL-PRF-55310
    ► Electrical testing of crystal filters according to IEC 60368
    ► Electrical testing of SAW Devices according to IEC61019 (SAW resonators) and IEC 60862(SAW filters)
    ► Environmental testing according to IEC 60068, AEC-Q, MIL-STD-202, MIL-STD-883 and others
    ► Testing according to ESA and other Space specifications
    ► Testing to customer specifications

     
  • Screening Tests and Component Selection Tests

    ► For High Reliability applications such as Downhole, Military, Aerospace and Space
    ► As immediate measure in case of failures, before the corrective actions are effective

     
  • Qualification Tests for Commercial, Automotive, MIL, Aerospace and Space

    ► Capability approval test procedures
    ► Qualification approval test procedures
    ► For crystals and resonators according to IEC 60122, IEC 60444 and MIL-PRF-3098
    ► For oscillators according to IEC 60679 and MIL-PRF-55310
    ► For crystal filters according to IEC 60368
    ► For SAW Devices according to IEC61019(SAW resonators) and IEC 60862 (SAW filters)
    ► Environmental testing according to IEC 60068, AEC-Q, MIL-STD-202, MIL-STD-883 and others
    ► According to ESA and other Space specifications
    ► Qualification testing to customer specifications (also shared test strategies)

     
  • Training Courses, Seminars and Workshops

    ► Annual "Quartz Seminar" at the Technical Academy Esslingen (TAE). Please see our calender for the next event.
    ► Inhouse Seminars at your facility with topics focussing on your particular needs
    ► Workshops with experimental demonstrations, e.g. on Crystal Measurment Techniques

     
  • Consulting Services about various topics

    ► Identification and solving of specific problems in short terms (Failures in production testing, field failures, zero-miles failures)
    ► Standards for Frequency Control Products
