Introduction to FPC material Polyimide Introduction to Polyimide, a material for flexible boards: (1) Polyimide has excellent heat dissipation performance and can withstand thermal shock during high temperature processing of lead-free soldering; (2) For small devices that require more emphasis on signal integrity, most device manufacturers tend to use flexible [...]

At present, electronic equipment is still used in printed circuit boards as the main assembly method for various electronic devices and systems. The practice has proved that even if the circuit schematic design is correct, improper design of the printed circuit board will also have an adverse effect on [...]

Factors affecting PCB prices When we design a project, we care more about layout and wiring, and often overlook the additional PCB manufacturing cost in the design. We discuss what factors in the design affect the price of pcb and avoid increasing costs for customers. Number of wiring layers: [...]

Through the analysis of the parasitic characteristics of vias, we can see that seemingly simple via in high-speed PCB designs can also bring great negative effects to circuit design. In order to reduce the adverse effects of the parasitic effects of vias, you can do as much as possible [...]

About the relationship between PI and FPC boards PI refers to a polyimide resin material, which is now widely used in various fields and is a very good material. Some people call PI a symbolic material that promotes the reform of electronic products. . We mainly explain the location [...]

PCB board is an important electronic component, and it is the mother body of all electronic components. It has become more and more complex since the beginning of the last century. From a single layer to double layer, four layers, and multiple layers, the design is also difficult. Increasing. [...]

PCB through hole introduction Via is one of the important components of a multi-layer PCB. The cost of drilling is usually 30% to 40% of the cost of PCB board. Simply put, every hole in the PCB can be called a via. From the perspective of function, the vias [...]

How to produce FPC double-sided anti-oxidation board Select materials This is one of the main factors affecting the production of FPC flexible boards, so the materials selected will affect the entire circuit board production process. Cutting and drilling This is a step that every FPC board must go through. [...]

Single-sided PCB process flow: Blanking → screen printing → etching → removal of printing materials → hole processing → printing mark → coated flux → finished product. The process flow of multilayer printed boards: Inner Material Processing → Positioning Hole Machining → Surface Cleaning → Inner Layer Traces and [...]

Five steps of PCB copying PCB copy board, under the premise that there are already electronic products and circuit boards, use the reverse technology to reversely analyze the circuit board, and carry out the technical documents such as the PCB file, bill of materials and schematic diagram of the [...]
