In the 1990s, electronic devices continued to shrink, leading to a greater demand for PCBs in mechanical manufacturing. The Internet was also born and began a revolution, gradually popularizing personal computers worldwide. Later, mobile phones were introduced, and without the advancement and minimization of PCB technology, this technological leap would not have occurred.
In the 2000s, PCBs became more complex, functional, and smaller in size Especially the design of multi-layer and flexible circuit PCBs makes these electronic devices more operable and functional, with small-sized and low-cost PCBs
At the beginning of the 21st century, the emergence of smartphones propelled the development of HDI PCB technology Simultaneously retaining the micro holes drilled by laser drilling, stacking through holes begins to replace staggered through holes, and combined with "any layer" construction technology, the final line width/line spacing of HDI board reaches 40 μ M
This arbitrary layer method is still based on the subtraction process, and it is certain that for mobile electronic products, most high-end HDIs still use this technology However, in 2017, HDI began to enter a new stage of development, shifting from a reduction process to a pattern-based electroplating process
Nowadays, various types of printed circuit boards, including rigid PCBs, rigid flexible junction boards, multi-layer printed circuit boards, and HDI PCBs, are widely used in the market and have undergone multiple evolutions. The circuit board manufacturing industry is still making great strides. The future impact of PCB is expected to go further in the following major areas.
