-Mobile phone test cards (also known as white cards) are used for signal testing in communications industry production. It is often used for mobile phones to cooperate with comprehensive testers and self-built networks to conduct interference-free comprehensive testing of mobile phones. During production, mobile phones need to perform relevant signal tests on finished products, but large-scale screen display requires more manpower, material resources and testing time, which makes the production process difficult. The complexity and cost increase. The test card can realize the only path from the signal to the instrument to the mobile phone, making the test environment more concise and solving this complicated problem. The test card can carry out coupling test and bit error rate test, and has complete equipment and can be used for terminal and comprehensive tester testing, etc.
2. Brands of test instruments that the product is suitable for:
Suitable for various foreign and domestic test instruments such as Agilent, Anritsu, Rohde, Schwarz, R, D, D, D, etc. as well as self-built network etc.
Three: Product quality assurance:
Our company's test cards use special chips/compatible-contact compatible designs produced by internationally renowned semiconductor manufacturers. They are suitable for all mobile phones and equipped with special systems to fully comply with the requirements for mobile phone cards. Specification of the special semiconductor silicon lining ensures that the card can withstand pressure in Newtons per square meter. (Standard is Newton/per square meter) Suitable for use in industrial production lines. It adopts ultra-long life to ensure that the number of reading and writing times is more than 10,000 times. (The standard only requires 10,000 times of reading and writing per mobile phone according to general production line measurement requirements. Ten thousand mobile phones can be measured.) The patented chip protection layer ensures card security against electronic attacks. Pressure resistance. The above special card coating is antistatic (D) waterproof (hour immersion test) special card body material (mixed high temperature) high temperature resistance and can work normally for more than hours. Temperature shock test
Our company's products are authorized by the National Integrated Circuit Card Registration Center to use several imported Samsung and other chips [authorized scope with contact card chip series]. The physical properties, chemical resistance, and contact electrical properties of all smart cards have passed the inspection of the National Computer Quality Supervision and Inspection Center and the Card Quality Supervision and Inspection Center of the Ministry of Information Industry, providing authoritative quality assurance.
