Eldaas announces their distribution partnership on security & surveillance solutions with D-Fence, Israel.

Bangalore, KA, India – 5th June 2020

Eldaas Technologies India Pvt Ltd announces their distribution partnership on security & surveillance solutions with D-Fence Electronic Fencing and Security Systems Ltd, Israel.

In today’s scenario camera-based security alone is not enough to detect intruders or prevent them from entering. We need a stronger and proven solution which can’t be cracked down by any person.

Our partner D-Fence solutions based out of Israel, spent many years on studying & researching in this field. They have developed a variety of perimeter security solutions using cutting edge technology which can meet the need of a private property to a large defense establishment.

Eldaas Technologies, an expert embedded solutions provider for defense & Aerospace, Automotive and Industrial Embedded partnering with D-Fence in solutioning to various customers in India.

The available solutions are from footstep detection to an electronic fencing with a combination of camera and various sensors for accurate identification and differentiation between animals and human.

“We believe that our partnership with D-Fence, will enable us to serve our customers with value added solutions in the Defence and security domain” says Co-founder & CEO Mr. Suneel Kumar.

“We are happy to appoint Eldaas Technologies as our Authorized Representative in India. By entering this relationship, we anticipate an exponential growth for us in this region” says, D-Fence solutions, Israel.

ENVIRONMENTAL STRESS SCREENING

Reduced Cost – Increased Profitability – Satisfied Customers

1.     Objective:

Objective of this article is to summarize the concept of Environmental Stress Screening (ESS), its benefits, process and applicability for various stages in the manufacture of Electronic Equipment.

2.     Environmental Stress Screening:

Environmental Stress Screening (ESS) is a means of screening electronic   assembly’s at the most cost effective point of manufacture to expose defects that can’t be detected by visual inspection or electrical testing. These defects are typically related to defective parts or workmanship and are normally found as early field failures. ESS works by subjecting 100% of a group of products to an environmental stimulus or a set of stimuli for a predetermined time for the purpose of forcing failures to occur before shipment, in fact, at the board level. Failures are normal and expected when ESS is applied. This makes ESS radically different than more conventional certification testing which requires failure free operation as proof of reliability. ESS is not a test, it is a process

Key factors for proper ESS implementation are:

  1. The stress environment must not exceed the electrical or mechanical limits of the product.
  2. An optimum level of stress must be applied to the product.

Expected benefits:

  1. Reduced field repair expense
  2. Fewer defects and waste
  3. Elimination of less effective screening procedures
  4. Lower unit cost
  5. Increased product value
  6. Improved customer satisfaction
  7. Better return on investment (ROI)

Test Flow Chart

ESS may be conducted at any point in the manufacturing flow. It may be applied at more than one point, if justified. For electronic products, the three most common points are at the

  1. Component level,
  2. Sub-assembly level (circuit card level) and
  3. Final assembly level.

Because the types of defects are different at each level, the stress conditions may be different at each level.

Following are the screening test will be carried out at different stages of product life cycle.

ComponentSub-assemblyAssembly/SubsystemSystem
Temperature-Power OffTemp.Cycling-Power OffTemp.Cycling-Power OnBurn-In:Power On(Dynamic)
Temp.Cycling-Power OffVibration- Power OffVibration-Power On
Temperature-humidity-bias

ESS is product-specific, since each product has its own set of potential defects, and since the applied ESS stresses affect each product differently. Even though the ESS process must be set up separately for each product, there are many common features of both products and stresses which cause many ESS processes to be similar.

The stresses applied in ESS are those which are expected to precipitate manufacturing defects. They are not necessarily those which the product will see in service. The two most common ESS stresses for electronic products are temperature cycling and vibration. They may be applied sequentially or simultaneously. ESS may be conducted anywhere in the manufacturing process flow.

7 Endurance 168hrs at room temperature for sonars, communication equipment AIO systems, NAV aid equipment etc. and 08 hrs for radar equipment with 04 hrs ON The equipment/ system is to be subjected to endurance test post FATS  

4.     Summary

ESS is a process to expose defective components and workmanship defects at the manufacturing stage and avoid their occurrence in early life of the product in the field.  Though they look similar to environmental tests, they are not environmental tests which are carried out to bring out the defects due to design and engineering.
