Now Si8000m and Si9000e also have the new option of XFE cross modeling function, Polar Instruments can provide. More than 98% of PCB manufacturers including Hongtai use Polar.

In the production of electronic products, there will be a production process of printed circuit board. Printed circuit boards are used in electronic products in all industries. It is the carrier of electronic schematic diagram that can realize the design function and turn the design into physical products

1. Introduction to chips What is a chip? A chip is an integrated circuit that can be compared to the brain of an electronic device. The components on a chip can perform various tasks, such as processing information, storing data, performing calculations, and controlling operations. Why is it called a chip? "Core" represents the core and center, and "chip" represents a thin piece or fragment. A chip is a thin piece made of semiconductor materials, which, as the core part of the entire circuit system, integrates key circuit structures.

When designing a four layer PCB circuit board, how to design the stack? Theoretically, there can be three schemes

the difference between longitude and latitude causes the change of substrate size; Due to the failure to pay attention to the fiber direction during shearing, the shear stress remains in the substrate.

The difference between the excimer laser and the impact carbon dioxide laser through-hole of the flexible circuit board:
