FAQ

Why EMC test is required?

Electro-Magnetic Compliance (EMC) test is required by National or International standardization or legislation in the target market. It is also required by your customers in their specifications. The EMC tests are generally comprised of two groups: 1. Tests the equipment under test immunity to interferences that originate in other electrical equipment that operates nearby. 2. Test that verifies the radiation levels of the equipment under test do not exceed limits that may interfere with other electrical equipment operating in its vicinity.

Why Radio test is required?

Communication services utilizing radio channels are controlled by target market legislation and regulated by bodies such as FCC in the USA and the Notified Bodies under the R&TTE Directive in the EU. The purpose of the legislation is to control proper utilization of the frequency bands allocated by the regulation bodies in order to reduce interferences and to reduce safety hazards for those exposed to Radio frequency radiation.

What is the Product Safety purpose?

The Safety tests performed in the lab are based on the international standards and legislation in the target markets. The purpose of those tests is hazard assessment and prevention to the user under standard operating conditions or during a failure. The hazards assessed are such as: electrical shock, product overheating, fire, various sources radiation and many more.

What is the purpose of Environmental Test?

Environmental test are usually required by your customer's product specification document. Those tests are required for product's quality proof and for proof of the product's ability to operate in various environments it was designed to. The tests are performed on the products prototype and before product's delivery to the customer. The tests will be performed based on the application applicable standard - military or commercial and the product will be tested either operational or packed for storage or transportation. Environmental testing may be use as an axcelerator for statistical reliability proof.

What is HALT?

HALT - Highly Accelerated Stress Screening - is a test process of products prototypes intended to increase final product reliability. The accelerated test combines thermal shock and random vibration in six degrees of freedom. Stress profile is adapted for each product individually based on its basic capabilities. During HALT the product itself is operational and its being monitored for performance quality. The stress continues until the product's function fails. Each failure is analyzed for it root cause, repaired and the test continuse until the products technological limit.

HALT enables to increase safety margins of the product, decrease its vulnerability and increase its reliability.

What is HASS?

HASS - Highly Accelerated Stress Screening - is a complementary process to HALT. It is performed using the same test equipment as HALT. Its purpose to screen-out production induced failures. Its profile is based on the limits characterized during HALT therefore it can effectively screen the product without affecting the reliability or its life span. HASS is much shorter and faster process than conventional ESS or Burn-im. HASS can be used as a statistical tool to control the average outgoing quality level (AOQL).

What is Calibration and how to ensure its quality?

Calibration is defined as comparison of a test equipment parameter measurement capability, its resolution and accuracy with a higher standard. In order to assure professionalism and high performance quality of a Calibration lab, it is required that the Calibration lab is ISO17025 accredited by a third party (ILAC). ISO17025 accreditation assures Calibration lab staff high performance quality, high quality test equipment used and therefore high result repitability. The ISO17025 accreditation scope of the Calibration lab is part of the accreditation certificate and it can be also found on the web site of the accreditation body. Calibration lab may issue calibration certificate under scope only for those parameters it is accredited for.
