So, what is the most important thing in maintenance? 1.Classification of equipment…
How does the lamination of multi-layer FPC flexible PCB accomplish? What is the difference between the lamination of multi-layer FPC flexible PCB and traditional rigid PCB? Following is a brief introduction of multi-layer FPC lamination technology. First of all, the multi-layer soft PCB lamination process flow: lamination, die opening, feeding, die closing, pre-pressing, forming, cooling…
Manufacture of flexible printed circuit board The production process of flexible printed circuit boards is basically similar to that of rigid boards. For some operations, the flexibility of laminates requires different devices and completely different treatment methods. Most flexible printed circuit boards adopt a negative approach. However, there are some difficulties in the mechanical processing…

The basic characteristics of printed circuit board depend on the performance of the substrate, to improve the technical performance of printed circuit board must first improve the performance of printed circuit board, the basic characteristics of PCB depend on the performance of PCB. To improve the technical performance of PCB, it is necessary to improve…
Circuit board goldfingers are special part which needs to be processed by gold plating technology when processing circuit board, but when drawing circuit schematic diagram, there is no special golden finger component. Different plates need different number of golden finger, which can not be unified into components. In fact, when drawing a schematic diagram,…
The assembly of double sided flexible PCB is basically the same as that of rigid PCB components. In the actual manufacturing process, operators will adopt different processes according to the different requirements of the process. Double sided flexible PCB is connected to rigid PCB: Double sided flexible PCB is easy to deform due to…
Blind and buried vias fabrication is an effective method to improve the density of multi-layer plate, reduce the number of layers and the size of plate surface, and greatly reduce the number of plated through vias. Most of the buried and blind vias are small vias with diameters ranging from 0.05 mm to 0.15…
The basic performance of edge finger connector can be divided into three categories: mechanical properties, electrical properties and environmental performance. 1. Mechanical properties As far as the connection function is concerned, the pull-out force is an important mechanical property. Plugging force is divided into insertion force and pull-out force (pull-out force is also called separation…
Edge plating slots are features commonly used in printed circuit boards (PCBs). These slots are cut into the edge of the PCB to provide specific functionalities or to facilitate connections to other components or devices. Here are some key points about edge plating slots: Functionality: Edge plating slots serve various purposes, including electrical connections, mounting…
At present, various flexible electronic devices are proposed for various applications, such as pulse and activity monitoring, electrolyte balance measurement and so on. This makes it difficult to generalize and universalize the electronic devices of flexible circuit boards. However, most of the flexible electronic devices proposed at present involve sensors, power supply, onboard data storage,…
With the increasing integration of IC, IC feet are more and more compact. Vertical tin spraying process is difficult to smooth the thin solder pad, which brings difficulties to SMT mounting. In addition, compared with gold plated circuit board, the shelf life of tin spraying board is very short. Gold plated circuit boards just solve…
The assembly process of half hole pcb is relatively cumbersome, which requires many processes. The following is a brief description. Firstly, the bare half hole pcb is transported to SMT workshop by PCB manufacturer. PCB bare board is sent to SMT equipment by feeder for patching. In front of the feeder, components are patched…
What is hard gold on PCB? Gold plating can be divided into hard gold plating solution and soft gold plating. Electroplated hard gold is alloy, so its hardness is relatively hard. It is suitable for use in places where friction is required. It is commonly used as PCB board edge contact point (commonly known as…
Printed circuit board (PCB) is a structural component composed of insulating material and conductor wiring. When the final product is manufactured, it will be equipped with integrated circuits, transistors, dipoles, passive components (such as resistors, capacitors, connectors, etc.) and various other electronic components. By means of wire connection, electronic signal connection and corresponding functions can…
