The Significance of Constructing ISO27001 Information Security Management System
After the rapid development of computer technology, network technology has been applied in a full range, and the ensuing information security problem has gradually received the attention of all sectors of society. Information security has not only been fully developed in the field of communication and data, but also involved in computer security, communication security and network security. To establish an information security system that conforms to modern enterprise business and management, improve information construction, and reduce security loopholes through the IS027001 information security management system is of great significance to the long-term development of enterprises.
The benefits of constructing IS027001 Information Security management system：
(1) It can effectively protect information resources and promote the orderly, healthy and sustainable development of informatization process. IS027001 is a standard system in the field of information security management, similar to the quality management system certification IS09000 standard.
(2) When the enterprise passes the IS027001 certification, it is equivalent to the enterprise's information security management is scientific and reasonable, and can effectively protect customer information and internal information. After the IS027001 Information security management system certification, you can have a number of benefits or advantages. The introduction of information security management system can coordinate information management at all levels, simplify management links and improve management efficiency.
(3) Through the IS027001 information security management system certification, it can also increase the credit degree of e-commerce exchanges between enterprises, establish a trusted cooperative relationship between the website and trading partners, and deepen the development of enterprise business information.
(4) Through the IS027001 information security management system certification, it can promote the relevant enterprises to achieve information security commitments, eliminate the distrust of customers and employees, and improve business performance. In addition, it can even gain international recognition so that the business can expand overseas.
The significance of constructing IS027001 information security management system：
In essence, information security management system is an information security management mode, its purpose is to improve the management level of enterprises, promote the benign development of enterprises, ensure the security of various information resources of enterprises, and not be stolen by the outside world to cause negative impact on enterprises. Information security management system with many standards, the main reference is IS027001 information security management standard. To achieve enterprise information security management standardized and orderly through the reference of the standard, so that enterprise information security management can be more scientific and reasonable. Information security management develops with the development of information technology. In the information society, information resources have become a precious resource and has high economic value.
Under the realistic background of information security problems, strengthening the construction of information security management system has extremely important practical role and future significance. Under the IS027001 information security standard, we develop advanced technologies, carefully evaluate information security risks, and build an information security management system that conforms to the current situation and future development of enterprises.
Thermal Cycling Test(TC) & Thermal Shock Test(TS)
Thermal Cycling Test(TC):
In the life cycle of the product, it may face various environmental conditions, which makes the product appear in the vulnerable part, resulting in product damage or failure, and then affect the reliability of the product.
A series of high and low temperature cycling tests are done on the temperature change at the temperature variation rate of 5~15 degrees per minute, which is not a real simulation of the actual situation. Its purpose is to apply stress to the test piece, accelerate the aging factor of the test piece, so that the test piece may cause damage to the system equipment and components under environmental factors, in order to determine whether the test piece is correctly designed or manufactured.
Common ones are:
Electrical function of the product
The lubricant deteriorates and loses lubrication
Loss of mechanical strength, resulting in cracks and cracks
The deterioration of the material causes chemical action
Scope of application:
Module/system product environment simulation test
Module/System Product Strife test
PCB/PCBA/ Solder Joint Accelerated Stress Test (ALT/AST)...
Thermal Shock Test(TS):
In the life cycle of the product, it may face various environmental conditions, which makes the product appear in the vulnerable part, resulting in product damage or failure, and then affect the reliability of the product.
High and low temperature shock tests under extremely harsh conditions on rapid temperature changes at a temperature variability of 40 degrees per minute are not truly simulated. Its purpose is to apply severe stress to the test piece to accelerate the aging factor of the test piece, so that the test piece may cause potential damage to the system equipment and components under environmental factors, in order to determine whether the test piece is correctly designed or manufactured.
Common ones are:
Electrical function of the product
The product structure is damaged or the strength is reduced
Tin cracking of components
The deterioration of the material causes chemical action
Seal damage
Machine specifications:
Temperature range: -60 ° C to +150 ° C
Recovery time: < 5 minutes
Inside dimension: 370*350*330mm (D×W×H)
Scope of application:
PCB reliability acceleration test
Accelerated life test of vehicle electric module
LED parts accelerated test...
Effects of temperature changes on products:
The coating layer of components falls off, the potting materials and sealing compounds crack, even the sealing shell cracks, and the filling materials leak, which causes the electrical performance of components to decline.
Products composed of different materials, when the temperature changes, the product is not evenly heated, resulting in product deformation, sealing products cracking, glass or glassware and optics broken;
The large temperature difference makes the surface of the product condense or frost at low temperature, evaporates or melts at high temperature, and the result of such repeated action leads to and accelerates the corrosion of the product.
Environmental effects of temperature change:
Broken glass and optical equipment.
The movable part is stuck or loose.
Structure creates separation.
Electrical changes.
Electrical or mechanical failure due to rapid condensation or freezing.
Fracture in a granular or striated manner.
Different shrinkage or expansion characteristics of different materials.
The component is deformed or broken.
Cracks in surface coatings.
Air leak in the containment compartment.

The Relationship Between the Altitude of the Standard Atmosphere and Air Temperature and Pressure
The standard atmosphere referred to here refers to the "1964, ICAO Standard atmosphere" adopted by the International Civil Aviation Organization. Below an altitude of 32 km, it is the same as "1976, U.S. standard atmosphere". Changes in air temperature near the surface (below 32 km) are:
Ground: The air temperature is 15.0℃, the air pressure P=1013.25mb= 0.101325MPa
Temperature change rate from ground to elevation 11 km: -6.5 ℃/ km
On the 11km interface:
The air temperature is -56.5 ℃ and the air pressure P=226.32mb
Temperature change rate at elevations of 11-20 km: 0.0℃/ km
Temperature change rate at altitude 20-32 km: +1.0/ km
The following table lists the temperature and pressure values of the standard atmosphere at different altitudes. In the table, "gpm" is the altitude meter, and its negative sign represents the altitude
