Why your mass production PCB assembly cost so expensive? I have known some friends choose cheapest PCB, but spend expensive in mass production PCBA case. And ask me why resulting in this situation. If you have read our articles, you must find the cost breakdown of 2 layer PCB is differ from multilayer PCB. To […]

Why we discuss the way reduce costs in 2 layer and 4 layer PCB manufacture If you have read our articles, you will find the cost breakdown of 2 layers is different with the 4 layer PCB board. And the reduce cost also have different ways. But one of my friends asks me how to […]
Why we discuss the secrets of multilayer PCB board cost There were many secrets in different industry, most of sale or boss doesn’t want their customers know that. First of all Emma wants to clear that we all discuss factor were related the cost of multilayer PCB board, and not against anyone or PCB manufacturer […]
This post we are going to find a way to reduce cost use high quality Fr-4 PCB base material. Even there were many difficulties to achieve this goal, we also want to discuss to handle this issue. Emma thinks this is a very complex issue, we must separate many part to discuss. The composition of […]
This article we will discuss why some companies still use low quality FR-4 PCB base material to produce. If you have done some research, you will find this is a very complex problem. Many differing reasons to resulting in use low quality FR-4 PCB base material. Emma has list top 3 reasons that may use […]
The FR-4 PCB base material is used widely in China We have discussed many articles about FR-4 PCB base material。 If you have read some of them, you may know the FR-4 PCB base material is used widely in China. Most of conventional multilayer PCB boards were used FR-4 PCB base material. There were many […]
You have to know the common sense of PCB base material. There were many PCB base material use of different PCB manufacturer. This post will discuss the PCB base material use by China aluminum PCB manufacturers. There are 6 major different materials, FR-1 FR-2, FR-3, FR-4, CEM-1, CEM-3 (except Isola FR406N, Rogers, Aluminum), used to […]
The common sense of CEM PCB base material Compare the performance and the reliability, CEM PCB base material is better than FR-4. It is a complete replacement of FR-4. But it’s not popular in China, so it is not cost effective to use it. CEM definition introduces We are going to introduce another PCB base […]
Why introduce FR PCB base material? FR is the most normally material for PCB manufacture. To learn some FR PCB material is beneficial for purchase process or design process. Most important to learn FR PCB material knowledge, can help you understand why the PCB process should manufacture so many process steps. FR -1 and FR […]
Why we introduce PCB design tips During PCB design, engineer should consider many factors. But there were some very easy to ignore by the green designer PCB engineer. This is why Emma summarized this topic on our website. And there was another reason to introduce design related factors, it really benefit to all engineers. Many […]
