Shenzhen Huahai Smart Card Co., Ltd. specializes in testing white cards and is a manufacturer of testing white cards for all types of mobile phones.
Welcome to inquire and negotiate at the telephone number:
1. Brief description of product use: test card, test card, - card, - card, test card, test card, test card, R test card, mobile phone test, test card, test card, mobile phone test card (also known as white card), use Signal testing for communication industry production (Long-term evolution) is a long-term evolution of technical standards formulated by 3 organizations. The project was officially established and launched at the Toronto meeting on March 3, 2019. The system introduced key transmission technologies such as multi-antenna and multi-antenna, significantly increasing It improves the spectrum efficiency and data transmission rate (the peak rate can reach uplink b/, downlink b/), and supports a variety of bandwidth allocation: .3 and etc., the spectrum allocation is more flexible, the system capacity and coverage are significantly improved. The wireless network architecture is flatter ization, reducing system delay, network construction costs and maintenance costs. The system supports interoperability with three other systems. - It has become the most widely adopted standard in countries and regions in the world and has the richest types of terminals. .). Commonly used in mobile phones, mobile phones, mobile phones, mobile phones, mobile phones, R mobile phones, mobile phones, with comprehensive testers and self-built networks to conduct interference-free comprehensive testing of mobile phones. Mobile phones require relevant signal testing of finished products during production, but large-scale A poor screen requires more manpower, material resources and test time, which complicates the production process and increases costs. 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 well solving this complex problem. question. The test card can be used for coupling testing, bit error rate testing, and has complete functions and can be used for terminal and comprehensive tester testing.
2. Brands of testing instruments that the product is suitable for:
Suitable for various foreign and domestic testing instruments such as Agilent, Anritsu, Rohde, Schwarz, Galaxy Highlights, etc. Networks built by mobile phone manufacturers or operators themselves, etc.
Three: Product quality assurance:
Our company's test card, test card, - card, - card, test card, test card, test card, test card, R test card, mobile phone test, test card , test card, mobile phone test card adopts special chips produced by internationally renowned semiconductor manufacturers, 3/compatible-contact compatible design, suitable for all mobile phones. Equipped with a dedicated system, it fully complies with mobile phones, 3 pairs of mobile phones, mobile phones, etc., our company's Various specifications of the test card include a special semiconductor silicon lining to ensure that the card can withstand the pressure of Newtons per square meter. (Standard is Newton/square meter) It is 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. (Standard 3 only requires 30,000 times. According to the general production line measurement requirements, the number of reads and writes per mobile phone is times, and it can test 10,000 mobile phones.) The patented chip protection layer ensures card security and prevents electronic attacks. Pressure resistance. The above special card coating, antistatic (), waterproof (hour immersion test) special card body material (B mixed high temperature), high temperature resistance, can work normally for more than 1 hour. Temperature shock test
Our company's products are authorized by the National Integrated Circuit Card Registration Center to use several imported chips from Samsung, Hitachi, Philips, etc. [Scope of authorization: () contact card chip series]. The physical properties, chemical resistance, and contact electrical properties of all tested smart cards have passed the inspections 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.
