The weak current/home appliance category refers to all electronic devices that operate at low voltage, covering a wide range from consumer electronics to industrial control equipment and communication infrastructure. Key characteristics include rapid advancements in miniaturization, enhanced functionality, energy efficiency, and smartification through IoT integration, leading to a noticeable shortening of product lifecycles. Applications are diverse, encompassing improved convenience in daily life, entertainment, and information communication, as well as FA (Factory Automation), measurement, and security systems. Services provided span the entire supply chain, from product planning, design, and development to mass production through EMS (Electronic Manufacturing Services), quality assurance, reliability evaluation, and after-sales service, as well as embedded software development and IoT platform construction. This field consistently demands high quality, reliability, and security.
