MATECH ASSOCIATES was established in 1989 in Scranton, PA, as an independent commercial, for profit materials testing and product development laboratory, serving chemicals, plastics, man-made materials as well as electronic, semi-conductor and divergent industries in the U.S. for thermal, mechanical and electrical techniques. Testing protocol and specification services were also offered internationally.
The organization has developed into a highly specialized materials consultancy for critical problem solving, training of laboratory personnel and group seminars in materials testing as well as electrical testing and evaluation, metrology, inspection, validation from the contact location given below.
NOTE: In 2001, a full line of thermal and electrical equipment plus laboratory furniture were donated to Wilkes University, Pennsylvania, by MATECH ASSOCIATES for laboratory facilities for students.

Developing and understanding of the electrical testing requirements for materials in electrical and electronic applications:
♦Study of electrical properties of materials is based mainly on their dielectric state,
intermediate between totally insulating and totally conducting characteristics.
♦This intermediate state is characterized in terms of a dimensionless pair of values
called DIELECTRIC CONSTANT and DISSIPATION FACTOR.
♦Dielectric Constant is measured as a ratio of the parallel capacitance of the material
under test to that of a dimensionally equivalent vacuum (air in practice).
♦Dissipation Factor is determined from the ratio of the resistive to the capacitive
component of current that results from an applied frequency.
♦It is thus possible to evaluate the extent to which the material is able to maintain
dielectric integrity within its designed limits.
♦Maximum Voltage Withstanding Capacity is expressed in terms of BREAKDOWN
VOLTAGE which provides a safeguard value against dielectric failure.
♦Resistivity measurements afford judgement of the magnitude of resistance through
the VOLUME and along SURFACE of the material.
♦Residual Conductivity or Insulation Resistance can be obtained from measurement of
♦Interfacial Charge Crowding from DISCHARGE CURRENT measurement can account for
low frequency AC losses.
♦STATIC DECAY testing by EIA-541 method can safeguard against damage of sensitive
electronic materials by ELECTROSTATIC DISCHARGE.
