With the continuous development of electronic industry, the size of components is also smaller and the density is bigger and bigger. PCBA board is the finished product formed after SMT patch, dip plug-in and PCBA test, and almost all electronic products need to use PCBA board.
Flexible circuit board is also called "soft board", which is a printed circuit made of flexible insulating substrate. Flexible circuit provides excellent electrical performance, can meet the design needs of smaller and higher density installation, and also helps reduce assembly process and enhance reliability. Flexible circuit board is the only solution to meet the requirements of miniaturization and movement of electronic products.
In the past, this interconnection technology was realized by wire interconnection. There are many kinds of flexible circuits
1. The double-sided flexible circuit is a kind of circuit with two conductive layers, which are respectively located on the two sides of the basic layer in the circuit; According to your specific requirements, the wiring pattern can be formed on the two sides of the substrate sheet, and the wiring on the two sides can be interconnected through copper plated through holes.
2. Bidirectional access flexible circuit, which is a kind of single-sided flexible circuit, the purpose of manufacturing this kind of circuit is to access conductive materials from both sides of the flexible circuit.
3. Multilayer flexible circuit is a combination of several single-sided or double-sided circuits with complex interconnection. Shielding technology and surface mount technology are often used in multilayer design.
4. Rigid flexible circuit integrates the advantages of rigid printed circuit board and flexible circuit. The circuit is usually interconnected by electroplating through holes between rigid circuit and flexible circuit.
At present, many electronic products are using PCBA board and flexible circuit. With the continuous development of electronic intelligent technology, the manufacturing technology of PCBA board is also improving. Runyuan electronics focuses on the processing and customization of PCBA board. Welcome to inquire.
