Description
Data Sheet

1. Industry Development Trend & PCB Technical Requirements

With the continuous development of electronic information technology, most electronic products are moving towards miniaturization and compactness, which puts forward higher requirements for the performance and size of printed circuit boards (PCBs). In the era of high-density interconnection technology, the line width, line spacing, and overall board size of PCBs are inevitably developing towards miniaturization and ultra-compactness. To adapt to this development trend, PCB designers and manufacturers are constantly updating design schemes and optimizing production processes, striving to meet the increasingly strict application requirements.

2. Challenges of Traditional Processes in Miniaturized PCB Production

Along with the trend of miniaturization and compactness, there are more and more PCBs with smaller external dimensions. For small-size PCBs, traditional processing technologies can no longer meet the production needs, especially in the communication microelectronics processing and assembly industry. The growing demand for ultra-small and ultra-thin high-frequency PCBs has become a key challenge that needs to be addressed urgently.

Traditional PCB production processes fail to meet the technical requirements of ultra-thin and ultra-small high-frequency PCBs, such as an overall size of less than 3mm, a shape tolerance of ±0.1mm, a board thickness of less than 0.3mm, and a smooth, burr-free surface around the board.

3. Key Specifications & Application Scenarios of Small-Size & Ultra-Thin PCBs

For small-size PCBs, the minimum overall size can reach 1×1mm, with a minimum shape tolerance of ±0.05mm. Ultra-thin PCBs can have a thickness of less than 0.1mm, and the board contour is required to be smooth without burrs. These high-precision, miniaturized PCBs are widely used in 5G communication component PCBs, SMD dielectric antenna PCBs, 5GHz band on-board SMD antennas, and interconnection device antenna PCBs, providing reliable support for the miniaturization of high-frequency electronic products.
