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!

Design for Manufacturing and Assembly: A Complete DFMA for PCB Design Guide
Key Takeaways DFMA covers both PCB fabrication and assembly: DFM addresses bare-board fabrication, while DFA addresses component assembly and related process constraints. The biggest decisions happen early: Package choice, layer count, and board outline are usually set well before Gerber export and become expensive to change later. Passing DRC does not guarantee a good footprint: Design rules can verify clearances and copper geometry, but they cannot confirm that a footprint matches the component data......
Get More From Every PCB Panel: Choosing the Right Panel Size
Key Takeaways Panel Drives Cost: Fabs price the whole panel, so maximizing utilization lowers per-board cost. 3 Panel Types: Distinguish raw sheets, fab working panels, and your delivery array. Keep Clearances: Reserve 5 mm process rails and 1–2 mm spacing around V-scores. Match Depaneling Method: Use V-cut (0 mm gap) for rectangles, tab routing for complex shapes. Test Both Orientations: Rotate boards 90° to find the best fit before ordering. PCB panel size is the one number on your order that you ne......

Understanding the Importance of DFM Analysis in PCB Design
Design for Manufacturing (DFM) analysis helps you on whether a printed circuit board (PCB) is fit for manufacturing, assembly, and sales. Early in the planning process, it looks for and fixes any possible problems arising throughout production. This will increase manufacturing efficiency and help to save expenses. DFM analysis is quite vital in the complex world of electronics, where even little design errors can create delays costing a lot of money. This article discusses the different types of DFM i......
Thermal Vias in PCB Design for Heat Management
Thermal vias are specialized vias designed to transfer heat from one layer of a PCB to another. These vias are placed near heat-generating components to create a thermal pathway, helping to dissipate heat and reduce the risk of overheating. They are often used with heat sinks, thermal pads, or copper planes to enhance their effectiveness. They are simply plated through holes (PTHs) that are located under a surface-mounted heat source component in a printed circuit board (PCB) that allow heat transfer.......
The Ultimate Guide to PCB Panelization: Tools and Techniques
Printed circuit boards (PCBs) are the backbone of modern electronics. One critical aspect of PCB manufacturing is panelization — the process of arranging multiple PCBs onto a single larger panel for efficient manufacturing and assembly. This technique allows multiple boards to be processed simultaneously, significantly reducing costs and improving production efficiency. In this article, we will provide a comprehensive guide to PCB panelization, covering the tools and techniques required for successful......
