Current Status Successfully passed the 17025 for SSL audit

Photometric test equipment is on order by second week of December Integrated burn-in test system for LM80 testing is currently available

Launch of cost-effective and higher test volume, revolutionary

stress test solution ITC360 - Innovative Thermal Controller 360

Convenience, safety and accuracy

Tests high-power devices and enables thermal regulation

Incorporates STS-developed IP

Closed loop to keep DUTs (Device-Under-Test) at temperature

within LM80 tolerances

Exceeds requirements, surpassing conventional burn-in methods

ITC360s Breakthrough Features

Convenience

State-of-the-art socket less and chamber less stress test, breaks the moldfor traditional stress test of high-power devices

Eliminates the use and quantity of burn-in ovens

1 ITC360 plate = 1-3 burn-in ovens

Removes variances due to test and test modules

Deployment of reliability testing - LM80 test

Cost-effective, yet ultra precision regulation

Provides DUTs the required ambience during test

Up to 24 DUTs can be tested at a time

Safety

Predictable, reliable integrity of test, user and customer protection andsafety

System automatically turns off in the event of possible setbacks

Safety redundancies



8/19

CONFIDENTIAL


Accuracy

Removes variances due to test and test modules Predictable performance and steady accuracy of results

Results have only a 1/2-1 variance vs. traditional burn-in results

which have a 5-10 variance

DUTs are tested at constant temperatures of 55, 85 or 105

Only 1 computer and software control different plates being testedat the various temperatures no room for errors or gaps in accuracy

Each DUT (i.e. LED) is individually controlled during testing by an individual

power supply
