A diferença entre a montagem de placas flexíveis rígidas e a montagem de sistemas de placas múltiplas

The Difference Between Rigid Flex Board Assembly and Multi Plate System Assembly One of the differences between rigid flex PCB and multi plate system assembly is the materials used for the substrate. In rigid flex PCB, the substrate material is typically woven fiberglass or an epoxy resin. However, these materials are not as reliable as […]

Quais são os factores comuns que causam a falha da placa de circuito impresso?

What Are the Common Factors That Cause PCB Circuit Board Failure? PCB circuit boards can fail for a variety of reasons. These include manufacturing defects, human error, and plating violations. While these reasons can’t be eliminated completely, they can be addressed during the design phase or during the CM’s inspection of the board. Human error […]

Estratégias de conceção de PCB para linhas de microfitas paralelas com base em resultados de simulação

PCB Design Strategies For Parallel Micro Strip Lines Based on Simulation Results Several PCB design strategies for parallel micro strip lines are presented in this paper.
