As one of the largest commercial test laboratory we’re well-equipped to provide chemical analysis in the engineering phase and the supply management phase.

Cleanliness Testing in the printed circuit board and assembly world encompasses the analysis of a specimen to determine the “type” or “amount” of a contaminant material.

This contaminant material can be potentially anything; the material can be large or small and can be unknown, known, expected, or unexpected to the analyst or the requestor. The use of various analytical techniques for cleanliness testing can assist in determining what material is present and how much of said material exists. The following is a sampling of techniques that are available.

Electrical Testing

The AQSCERT facilities are furnished with a wide variety of electrical test equipment to verify the operating conditions of electronic components, assemblies, and products under various types of environmental conditions. Offering a full turnkey solution for your electronic and electrical testing needs. We have the expertise to provide you the information you require whether it involves active monitoring as part of a larger test program or instead stand-alone analysis of a component, board or device. Material properties such as resistance, capacitance and inductance can be determined in addition to the electrical parameters of current and voltage.

  • Arc Resistance – The intent of the Arc Resistance test is to make a relative distinction between solid electrical insulating materials. The ability of the test specimens to resist an arc at a high voltage but with a weak current in the vicinity of the insulating surface is investigated. The test focuses on the time until tracking paths start to form.
  • Dielectric Breakthrough/Strength – Dielectric breakthrough refers to the highest intensity of an electric field that a material can withstand without losing its composition, while Dielectric Strength refers to the lowest intensity of an electric field at which a material breaks down.
  • Dielectric Constant – The capacity of a substance to keep electrical energy in proportion to the permittivity of the surrounding space is the dielectric constant. When the constant intensifies but other factors stay the same, the electric force field grows in density. Under these conditions, an object of a specific weight and measurement can hold an electric charge — as well as greater amounts of charge — for lengthier time spans. Capacitates of high value are among the materials that benefit from having high dielectric constants.
  • Surface Resistivity – This is the ratio of DC voltage between the length and width of an object’s surface. Surface resistivity is among the characteristics of a given material that can be studied and assessed in order to determine the overall value of the material — which can also be compared and contrasted with the resistivity of other materials. Overall, the testing process aids in the selection of materials.
  • Volume Resistivity – The volume resistivity is an inherent quality that measures how intensely a certain substance contradicts the direction of electric currents. Low-level resistivity suggests that the substance will easily permit the flow of an electric charge. The unit of resistance is known as the ohm, which is symbolized by the letter “R”. If a one-ampere current goes through a part where the voltage could be at least one volt different, the resistivity of that part is one ohm.
  • Conductivity – The conductivity of an item is the level at which matter carries out electricity, such as in the rate that heat manages to travel from one point on a given object to another. If a one-ampere current goes through a part in which one volt is present, that part has a conductivity of one Siemens. In most cases, when the voltage application is steadily maintained, the CD circuit will have a relative current to the conductance. If the latter is twice as much, so too will be the current. Likewise, a 1/10 conductance will correlate to a 1/10 current.
  • Thermal Coefficient of Resistance – A thermal coefficient refers to the difference in physical makeup of a substance once it has undergone a shift in temperature. Coefficients are identified for numerous processes, such as reactivity and the magnetic and electric attributes of substances. If the resistance level to electrical currents in a piece of material goes up in light of heightened temperature, it’s referred to as positive temperature coefficient (PTC).

Environmental Testing

Guarantee top performance in every condition

Environmental testing

Technical products are frequently exposed to natural, induced or combined environments like climatic and/or mechanical stresses. in some cases, every day of every week. Heat, cold, damp, wind and weather, extreme environmental conditions can have an extreme effect on how everything functions.

 What is environmental testing?

Environmental testing simulates the different climatic conditions and mechanical stress that products are exposed during their lifetime. Sometimes environmental testing will expose weaknesses in a product’s design or performance that could occur in service, particularly at extreme levels. Manufacturers are constantly striving to demonstrate that their products are safe, reliable and compliant in every operational scenario.

Why is environmental testing important?

In general, environmental tests can prove the reliability of your products. You can demonstrate that your products have the build quality to work perfectly, no matter what the conditions. During testing, possible weaknesses can be identified and product improvements can be initiated at an early stage.

While ensuring that your products perform correctly in various environmental conditions you can demonstrate compliance of your products with international regulations, thereby increasing the possibility to gain global market access quicker and much easier.

How we can help you?

With us as your partner, you can be confident that your testing needs are covered, no matter how complex your product is or to which industry sector it belongs to. With globally accredited environmental testing laboratories (EN ISO/IEC 17025), we verify the fitness for use of components, technical equipment and products.

Mixed Flowing Gas (MFG) Testing

Any product or system component that’s exposed to the air has the potential to incur damage due to atmospheric conditions and contaminants. For telecommunications, aerospace, automotive and other equipment, these conditions can lead to premature wear and potential liability issues down the line. As a result, air testing equipment has become an important part of the quality-control process.

Temperature and humidity

Temperature and humidity testing determines how components, subsystems and complete systems behave in severe environments that involve elevated temperatures and high or fluctuating relative humidity. The tests can be static with constant temperature and humidity, they can involve the cycling of both, they can be temperature-humidity bias tests (where the moisture is used to induce a failure in an electrical device) or some combination of all of these.

Mechanical Testing Services

The physical and mechanical testing of a product comprises a critical part of the product and development process. Applied physical force such as vibration, shock stresses, and strain can reveal the inelastic behavior of the material. Mechanical testing allows the product developers to understand the product better, identify vulnerabilities, and establish stronger quality control. Mechanical testing employs a variety of strength tests that can determine the suitability of a material or component for the intended application. It measures characteristics such as elasticity, tensile strength, elongation, hardness, facture toughness, impact resistance, stress fracture, and the fatigue limit.

Types of Mechanical Testing

To ensure materials and products perform accordingly, there are different types of mechanical testing they may undergo:

  • Break Strength Testing

One of the most common of all testing requirements is the determination of break strength. Break strength is generally the tensile or compressive load required to fracture or to cause the sample to fail.

  • Compressive Strength Testing

Compression testing is a very common testing method that is used to establish the compressive force or crush resistance of a material and the ability of the material to recover after a specified compressive force is applied and even held over a defined period of time.

  • Flexural or Bend Testing

There are generally two types of bending tests. Three-point bend and 4-point bend. The materials that are tested using the flex test method vary from metal, plastic, wood, laminates, particle board, dry wall, ceramic tile, to glass. Bending tests vary greatly based on the product being tested.

  • Peel Strength Testing

Peel Strength Testing is generally used to measure the bond strength of a material, typically an adhesive.
