How Are Printed Circuit Boards Manufactured?


Printed Circuit Boards or PCBs form the backbone of all major electronics like computers, televisions, smartphones, digital cameras, calculators, digital electronics, etc. A PCB is responsible to direct electrical signals through electronics, which satisfies the device’s electrical and mechanical circuit requirements. In short, PCBs are the components that tell the electricity where to go, thus bringing your electronics to life. PCBs direct the current around their surface through a network of copper pathways, the complex system of which determines the unique role of each piece of the PCB.
To design a PCB, circuit designers and fabricators communicate with each other over the manufacturing demands, which reduces the risk of errors in the designing stage. There are various stages involved in the production of PCBs, which are mentioned in this blog. A leading manufacturer like Miracle Aerospace takes care that all these processes are precisely followed to provide clients with the best quality PCB assembly from India.

Why Are Expanded Beam Connectors Preferred In Harsh Conditions?

When cable connections fail in a remote area, where there could be power failure and storm, connectors are a better alternative to be used in such harsh environments. And, even better are expanded beam connectors, which are specifically designed to operate in harsh environments of dirt, dust, water, oil, and the like.

Unlike in the case of butt-joint fiber optical connectors, there is no physical contact between fiber connectors in expanded beam connectors. These connectors thus employ a non-contact technique where the fiber is completely sealed behind a precision lens that increases the diameter of the beam by many orders of magnitude. This lens effectively enlarges the active area of the finer, thus providing a connector with significantly reduced dirt sensitivity and greater reliability, when used in adverse conditions. The lens expands and collimates the light emitting from an optical fiber, which is then transmitted through an air gap to a mating connector where the light is collected and focused by a second lens into a second optical fiber to complete the connection. This entire process reduces the connector’s sensitivity to dirt, dust, and all other types of contaminants that can otherwise disrupt the transmission between butt-joint connectors.
