The WCDMA test card of our company adopts the special chip produced by the international famous semiconductor manufacturer, 3v/5v compatible and 5-6 contact compatible design, which is suitable for all mobile phones Equipped with a special cos system, it fully complies with the specifications of 3G mobile phones and test cards. The special semiconductor silicon lining ensures that the card can withstand a pressure of 10 Newtons / square meter. (GSM standard is 4 Newtons / square meter) it is suitable for industrial production lines. It adopts ultra long-life EEPROM to ensure that the number of reads and writes is more than 100000. (the 3G standard only requires 30000 times. According to the measurement requirements of the general production line, the reading and writing times of each mobile phone is 10 times, and 10000 mobile phones can be measured.), The patented chip protective layer ensures the card security and prevents electronic attacks. Special card coating with voltage resistance above 6.5V, antistatic (ESD), waterproof (48 hour immersion test) special card body material (ABS mixed with high temperature PVC), high temperature resistance, 45 degrees can work normally for more than 4 hours. 75 degree temperature impact test

Our products are authorized by the national integrated circuit card registration center to use several imported chips such as Samsung [scope of authorization: s3c89k8 (ks88c92008) s3xc9xx IC card chip series with contacts]. The physical properties, chemical resistance and contact electrical properties of all tested smart cards have passed the inspection of the national computer quality supervision and inspection center and the IC card quality supervision and inspection center of the Ministry of information industry, with authoritative quality assurance
