High end boards refer to circuit boards with multiple layers, complex structures, and complex manufacturing processes in PCB (Printed Circuit Board). This type of circuit board typically includes high-density interconnect (HDI) printed circuit boards, chip size flip chip packaging (FCCSP), and rigid flex PCBs.
Application areas of high-order boards
High end boards are commonly used in high-end electronic products such as smartphones, tablets, laptops, etc. due to their complex structure and intricate craftsmanship. These products often require higher performance and stability, therefore there is a greater demand for high-order boards.
Technical characteristics of high-order boards
1. Complex manufacturing processes
The manufacturing process of high-order boards is relatively complex, involving various advanced manufacturing technologies such as laser direct imaging (LDI), electrochemical etching, photoresist development, and wet chemical etching.
2. High precision requirements
High order boards require extremely high precision, which is mainly reflected in their micro blind buried hole technology and micro hole coating technology. These technologies can effectively improve the density and performance of circuit boards.
3. Signal delay and interference control
The design of high-order boards should follow the principles of minimizing signal delay, maximizing signal integrity, and minimizing electromagnetic interference. This indicates that the quality of signals and the stability of the system need to be considered in the design of high-order boards.
In summary, a high-end board is a high-level product in PCB, representing the high-level application of PCB manufacturing technology. With the development of electronic technology, the demand for high-end boards will continue to grow, and their technology is also constantly advancing to meet market demands.
