Casio Computer Company, Tokyo, now uses BASF’s high-performance plastic Ultramid®Advanced N in its latest digital watch G-Shock GBD-H1000. The new flame retardant polyphthalamide (PPA) is used to manufacture the terminal header which sits on the terminal block and contributes to power charging and data synchronization. The high heat resistance as well as the exceptional mechanical and dimensional stability of the BASF material enhance the robustness, functionality and performance for which the G-shock watches are renowned. Due to its low moisture uptake and high heat deflection temperature, the BASF PPA is especially suitable for Surface Mount Technology (SMT) processes in electronics manufacturing as it prevents blistering or changes in dimensions of the processed part. With its intrinsic good laser transparency, Ultramid® Advanced N also offers more freedom for post-processing.
The newly launched GBD-H1000 sports watch serves as a fitness tracker with five different sensors. This requires a combination of technologically innovative and durable materials that are resistant to chemicals, shock and water especially during extreme sports. Ultramid® Advanced N displays excellent dimensional stability under humidity and heat as well as exceptional chemical resistance while having good adhesion to the metal terminal block. This prevents water leakage under harsh conditions and fulfills the waterproof requirements of Casio. The part made of the BASF PPA is about 1.2cm wide with a wall thickness of 0.2 mm and weighs less than 0.1 gram: The material thus contributes to downsizing while keeping high mechanical strength.
The successful collaboration between Casio, BASF and the Taiwanese connector company Aces Electronics has not only enhanced Casio’s ultimate tough watch design concept but also increased the speed and efficiency in delivering the right material for the G-Shock GBD-H1000. With the BASF PPA, Casio can make watches more durable while integrating new digital and interactive functions.
The terminal header made of Ultramid® Advanced N was manufactured by Aces Electronics. The terminal block and header are fixed to the motherboard by SMT, which is often applied in electronics manufacturing such as watch assembly today. So a stronger material than usual was required to meet the heat distortion temperature of up to 260°C during the production process using SMT. In extensive tests the BASF PPA proved its superior accuracy and quality during different production processes when compared to other materials currently available on the market.
