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!

SMT or Through Hole Technology？Which is Better for Your Project？
When designing and manufacturing electronics, one of the most important steps is selecting the appropriate assembly method. Nowadays we have through-hole technology and surface mount technology, which become the industry standards and are the two main approaches. The surface-mount technology (SMT) uses components that are perfectly aligned with the PCB surface. On the other hand through-hole technology (THT) uses leads that are placed into pre-drilled holes in the PCB and thereafter soldered. Consider......
