Introduction The avalanche photodiode (APD) is a highly responsive semiconductor device that converts light into electric signals using the photoelectric effect. First designed in 1952 by the Japanese engineer Jun-ichi Nishizawa, the APD has become a key component in various applications, especially in fiber-optic communication systems. In recent years, graphene layers have been added to […]

What is a Multilayer PCB? A multilayer PCB is different from a standard printed circuit because it uses more than two layers of copper. At least a minimum of three layers of foil, core, and materials are sandwiched together with prepreg (PP) or adhesive, forming strong boards. The multilayer boards are linked through vias, NC

What is Flex PCB? A flexible board like FPC or FPCB is designed with printed circuits and components that can be bent, folded, or even twisted without losing stability. Built on polyimide film and other substrates, the material ensures thermal stability and high Flexibility, making it reliable for automotive, medical, consumer, and wearables devices. Its
