Las placas de circuito impreso se utilizan en una amplia gama de dispositivos electrónicos, como ordenadores, teléfonos inteligentes y otros equipos digitales. Se han convertido en omnipresentes porque ofrecen una gran fiabilidad a bajo coste. Sin embargo, hay muchas formas diferentes de tratar la superficie de una placa de circuito impreso antes de ensamblarla con otros componentes en un dispositivo electrónico. ¿Qué...

Muchos clientes debido a la falta de comprensión del proceso de prensado de laminación de PCB, han sufrido un montón de pérdidas: obtener el tablero de múltiples capas, pero encontró deformación, estratificación es evidente, e incluso la existencia de graves problemas de calidad, tales como el circuito abierto de la capa interna. La razón principal es que algunas fábricas no...

General PCB producción hará la inspección completa después de la finalización de dos pasos: uno es la finalización del circuito (capa interna y capa externa); El segundo es después de que el producto terminado. La forma de comprobar el circuito después de la capa interna y externa El método de medición eléctrica es una de las pruebas de estrés....

After we finished PCB design, send it to the PCB factory for PCB prototyping or mass production, will enclose a copy of the PCB process document, one is to indicate the PCB surface finishes, and different PCB surface finishes, their cost, and the application situation is different. Firstly, why do we need special treatment of…

Problem Cause Effect LNA/tank circuit arrangement (receiver) Inductor orientation RF feedthrough Degeneration/π-network arrangement (transmitter) Inductor orientation RF feedthrough Shared ground vias between legs of π network Via parasitics Feedthrough, RF leakage Shared ground vias between receiver blocks Via parasitics Crosstalk, RF feedthrough,     RF leakage Long traces for decoupling capacitors Higher-impedance connections Reduced decoupling Wide component…

Introduction to wave soldering technology DIP plug-in and SMD adhesive process special wave soldering is one of the important processes of modern electronic manufacturing in PCB assembly industry, although it has been affected by SMT technology, but there are still quite a lot of electronic components can not be completely replaced by SMT packaging technology,…

Nowadays, the demand for electronic PCBA hardware terminal customers for electronic contract manufacturing services is increasingly strong. The traditional PCBA manufacturers, due to weak supply capacity, lack of price advantage, unstable supply, and low labor efficiency, lead to low conversion rate and face the problems of fewer and fewer customers. However, in the process of…

IoT chip to the module, the whole process of R&D and production The development of the Internet of Things and smart home has deepened the connection and interaction between people and things, making our lives more colourful, more convenient and more closely connected. The connection of people and things (equipment) depends on the Internet wireless…

what is a printed circuit board? The structure and characteristics of commonly used copper clad laminates Copper clad phenolic paper laminate A laminate made of insulating impregnated paper (TFS-62) or cotton fibre impregnated paper (1TZ-63) impregnated with phenolic resin and then hot pressed. In conclusion, with a single sheet of alkali-free glass impregnated cloth that…

For decades, printed circuit board assembly (PCBA) has successfully developed in a stable manner. It is a key component of various machines, computing terminals, automobiles and other electronic equipment. It is compact and efficient. In addition, they electronically introduce new inventions and technologies on a global scale. They have set off an innovation in the…
