As part of our electrical testing services, PTL regularly conducts dielectric constant and dissipation factor testing (e.g. ASTM D150) on various insulating materials. Dielectric constant (also known as relative permittivity, or Dk) is the ratio of the permittivity of a medium to that of a vacuum. In other words, it is the property of a material that determines the relative speed that an electrical signal will travel in that material. Dissipation factor (also known as loss tangent, or Df), is the ratio of the loss index (Κ”) to the relative permittivity (Κ’). Testing is most commonly conducted at frequencies between 60 Hz to 1 MHz. However, PTL also has the capability to test at higher frequencies, such as 1 GHz, 2.5 GHz, 5 GHz, and 10 GHz (X-Band). For more information about services offered by our electrical testing laboratories, please do not hesitate to contact us.
PTL is pleased to announce that it recently received a Supplier Trust and Recognition Award from Jet Propulsion Laboratory (JPL). The Certificate of Appreciate was presented by JPL’s Procurement Quality Assurance, for providing quality and integrity in critical testing support for JPL.
PTL has been re-approved by the Jet Propulsion Laboratory (JPL). As an approved supplier for JPL, the scope of approval includes preparation of metallographic specimens of printed wiring products (PWB) and evaluation of the finished microsections for the quality of the laminate system and the plated-through holes (PTHs). This includes PWB coupon testing.
Featuring PTL’s new SEM/EDS system, currently utilized for applications involving Failure Analysis, high magnification imaging, and elemental characterization: JEOL JSM-IT500 InTouchScope Scanning Electron Microscope (SEM) equipped with a Thermo Scientific UltraDry EDS Detector and Pathfinder X-Ray Microanalysis Software for Energy Dispersive X-Ray (EDS) analysis. A few major highlights of the instrumentation include examination in both high vacuum and low vacuum modes, a large specimen chamber, light element sensitivity down to beryllium, spectral imaging, and linescans.
Pacific Testing Laboratories, Inc. has completed the International Traffic in Arms Regulations (ITAR) registration process with the U.S. Department of State, Directorate of Defense Trade Controls (DDTC). ITAR compliance will allow Pacific Testing to better serve our Customers, in support of their current and future needs.
To enhance and increase its Vibration and Impact Shock capabilities, Pacific Testing Laboratories has recently added an Unholtz-Dickie Model SAB15F-S202-LP intermediate range Vibration System.
The performance of this Vibration System supports a wide variety of Vibration and Impact Shock capabilities, at g levels and weight-handling levels not previously available at Pacific. Applications include product development, design conformance, qualification, certification, and production screening to Military, Aerospace, Automotive, and Medical specifications.
The System is capable of performing to a variety of Test Methods, which may be found in MIL-STD-202, MIL-STD-810, MIL-STD-750, FED‑STD‑101C, or ISO 5344: 2004, etc.
The salient characteristics of the System are a usable Frequency Range of DC to 3500Hz; 100g peak positive and negative maximum Shock Pulse @ 18 pounds; 100g peak maximum Acceleration for Sine Vibration; 70g peak maximum Acceleration for Random Vibration; 2.0 inch displacement; 2500Hz Armature Resonance; Automatic Armature Centering; Isolation Mounting; ESD compatible, etc.
The System is under control of a Vwin II Controller, which controls the entire Vibration or Shock program from inside the workstation. The Controller features an Automated Calibration Kit, for Self-Test with an NIST-Certificate; it generates an MS Word report, on command. Typical programs are Random; Sine, both swept and fixed; Resonance Dwell; Classical Shock Pulse, etc.
The Test Engineer maintains full visibility over the Test Program at all times from his position in the Control Room; he is able to continuously monitor the vibration or shock levels, frequencies, sweep count, etc. In addition, the test engineer can immediately abort the test program in the event of an equipment or Test Sample failure.
PTL has recently added a new Perkin-Elmer Dual View Inductively Coupled Plasma-Optical Emission Spectrometer (ICP-OES), Model Optima 7000V.
With the ICP-OES, PTL can now simultaneously analyze a variety of elements in solution, with improved detection limits and the option to use either the radial or axial view modes.
Dual viewing allows for lower detection limits and wide working ranges for a variety of samples.
