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…

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…

How to choose circuit board components Deciding which PCB assembly to use can be a daunting task, because there are many different options to choose from. From deciding on the footprint of the component to checking the spare gate. It needs to carefully consider several different factors before deciding which printed circuit board component to…
