How to avoid breaking the board when the thin and narrow connection is broken?
In actual production, sometimes there are narrow and long connections, some of which may be wired. After the PCB is processed by V-cutting, the customer's force is uneven when dividing the board, and the force on the narrow place is weak. It is easy to break when breaking the board (at A in the figure below). At this time, we can change the way of jigsaw puzzles, and open a gap of 1.6-2MM between the boards, so that these narrow and long connection positions can be made out of the edge (as shown in B in the figure below), so that there is no need to break them. Open this place to avoid breaking the board.
Special attention: If the depaneling method is adopted, the width of the narrow and long connection position needs to be more than 1MM, and the length should be within 30MM. If the length exceeds this length, the connection position needs to be appropriately widened!

These carrier boards are characterized by their small size and a row of metalized castellated h......
Understanding the Importance of Annular Rings in PCB Design
Annular rings play a crucial role in printed circuit board (PCB) design, ensuring the proper electrical connection of two pads. The signal and current flow are characterized based on the placement of annular rings between two layers. Incorrect calculation of size and improper placement can lead to transient behavior and flicker noise in electronic components. In this article, we will consider all important steps to improve our design from annular ring issues, tangency, and breakout. An annular ring in......
