AXTAL CONSULTING Test House

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)
