Thin film resistors have a metallic film that is vacuum deposited on an insulating substrate. Thick film resistors are produced by firing a special paste onto the substrate. The paste is mixture of glass and metal oxides. Thin film is more accurate, has better temperature coefficient and is more stable.
PCB design translates electrical schematics into a functional product, and its quality directly impacts production efficiency and product reliability. For beginners, mastering PCB layout can be challenging despite familiarity with design software, and common issues often arise. Here, seasoned engineers from KKPCB share their PCB layout insights to help avoid these pitfalls and inspire best practices.
Proper PCB design requires careful planning and attention to detail, from schematic creation to component layout and wiring. Following these best practices ensures optimized signal integrity, reduces interference, and minimizes manufacturing issues, leading to higher-quality and more reliable PCB designs.
PCB layering or stacking is a way of stacking multiple printed circuit boards together while ensuring that there are predefined interconnections between them, allowing multiple printed circuit boards to be installed in the same device. These multi-layer PCBs can multiply the speed and functionality of a device and are composed of at least three conductive layers, with the bottom layer being composited with an insulating board
