PET Transparent Flexible PCB: A Cutting-Edge Solution for Advanced Electronics


Welcome to Bicheng PCB's blog, where we are excited to introduce our latest innovation: the PET Transparent Flexible PCB 3M Sticker. This cutting-edge PCB offers an array of features and benefits that make it an ideal solution for various applications, particularly those that demand transparency and flexibility. In this blog post, we will delve into the key properties, construction details, and typical applications of the PET Transparent Flexible PCB.

Unveiling the PET Transparent Flexible PCB:

The PET Transparent Flexible PCB is built with a single-sided adhesive transparent flexible PCB copper clad laminate known as SF490-500515SET. With an impressive visible light transmittance of 90.2%, this PCB ensures optimum clarity in visual displays and touch panels. It also boasts exceptional electrical properties, featuring a volume resistivity of 1.5×10^8 MΩ-cm and a surface resistance of 4.1×10^5 MΩ. Furthermore, the PET Transparent Flexible PCB offers remarkable dimensional stability and high bonding strength, ensuring reliable and durable performance.

Features and Advantages:

The PET Transparent Flexible PCB comes equipped with an extensive array of features that set it apart from conventional PCBs. Its exceptional transparency allows for the seamless transmission of visible light, making it the perfect choice for applications that rely on visual displays or touch panels. This innovation ensures crystal-clear visuals and outstanding touch sensitivity, greatly enhancing the user experience.

Furthermore, the FPC PET Board exhibits remarkable resistance to various chemicals, making it suitable for applications in harsh environments or those involving exposure to corrosive substances. Its excellent electrical properties contribute to reliable and consistent performance in a wide range of operating conditions.

Moreover, this flexible PCB is fully compliant with the EU RoHS directive. RoHS compliance guarantees that the pcb stiffener PCB is free from any harmful substances, such as lead, mercury, and cadmium, making it environmentally friendly and safe for use in various industries.

Construction Details:

The PET Transparent Flexible PCB is designed as a 1-layer flexible PCB. It consists of a single copper layer with a weight of 18 μm and a polyester core SF490 measuring 0.05 mm in thickness. With dimensions of 61mm x 41mm (with a tolerance of +/- 0.15mm), our PCB offers compact yet reliable construction. It features a minimum trace/space of 5/6 mils and a minimum hole size of 2.0mm. Notably, the PCB includes a 3M tape sticker for convenient installation. To ensure the highest quality, the PET Transparent Flexible PCB undergoes a 100% electrical test prior to shipment, meeting the IPC-Class-2 quality standards.
