Whether FCCL materials can meet production needs cannot only be determined by the manufacturer’s test report. When purchasing FCCL materials, a series of experiments must be conducted to test and prove them. Usually, for FPC factories, the following experiments are required to test whether FCCL can meet our needs: 1.Heat resistance test Testing equipment: high-temperature…
Flexible printed circuit board (FPC), also known as flexible board, has the advantages of softness, lightness, thinness and flexibility. With the rapid trend of information and electronic products towards lightness, thinness, shortness and smallness, it has been widely used in notebook computers, digital-related, mobile phones, liquid crystal displays and other uses. 1.Traditional flexible board materials…
This article discusses the causes of pinholes in the copper plating layer in the copper plating process of printed circuit boards, and proposes ways to find pinholes in the copper plating layer for reference. 1.Possible causes of pinholes in the copper plating layer: The chloride ion in the plating solution is too low, the air…
Today’s switching regulators and power supplies are more sophisticated and powerful, but one of the challenges they face is that the ever-increasing switching frequency makes PCB design more difficult. PCB layout is becoming a watershed that distinguishes a good switching power supply design from a bad one. This article will provide suggestions on how to…
I. High-density FPC flexible circuit graphic transfer process control technology In the high-density FPC flexible circuit manufacturing process, graphic transfer is a key control point and a technical difficulty. Its quality directly affects the qualified rate of FPC flexible circuits. Therefore, in the production process, the following points must be achieved: II. In the process…
Content: Crosstalk is perhaps the most difficult to understand and predict in high frequency circuits, however, it can be controlled and even eliminated. As switching speeds increase, modern digital systems encounter a series of problems, such as signal reflection, delay fading, crosstalk, and electromagnetic compatibility failure. When the switching time of integrated circuits drops to…
FPC is a flexible circuit board, which belongs to a type of PCB circuit board. FPC soft board is widely used, such as FPCC connector, FPC antenna, wireless charging coil array, etc. So what materials are FPC made of? 1.Raw materials (1) Glue material and non-glue material; the copper on the material is divided into…
Signal isolation allows digital or analog signals to be sent without a galvanic connection across the barrier between the transmitter and receiver. This allows the difference between the ground or reference level outside the transmitter and receiver to be as high as several thousand volts and prevents loop currents between different ground potentials that could…
When analyzing the prospects of the domestic FPC market in 2023, we need to consider many factors. First, market demand will continue to grow, especially in the fields of smartphones, tablets, automotive electronics, wireless terminals, etc., which have great demand and value and will become the core driving force for the development of the FPC…
Content: To successfully use today’s SOCs, board-level and system-level designers must understand how to best place components, route traces, and utilize protective components. They are called digital cellular phones, but they contain more analog functions than the previous varieties of so-called analog cellular phones. In fact, any system that needs to process continuous state values…
