Avoiding Ambiguities for Non-Standard PCB Shapes

- 1. Routing Only Along the Outer Layer
- 2. Routing Along the Indents
Typically, PCBs have regular rectangular shapes. However, nowadays, many PCBs are becoming smaller in size, and with the changing market, they are incorporating more functions and accommodating more diverse casing shapes. This has led to more complex designs, especially for non-standard shapes that often require more care in design and manufacture.
Now, let's explore the different outcomes that can arise due to the improper design of non-standard shapes.
1. Routing Only Along the Outer Layer
(Green line in the image is the track of the router bit) The final result will look like the image below:
2. Routing Along the Indents
For this kind of non-standard design with ambiguity, different outcomes can emerge. Some design engineers might be careless and might simply say "produce it as per the original drawing." In such cases, the result might be:
The produced board could be like this:
A PCB file should convey your manufacturing intentions clearly. Engineering design should be rigorous and meticulous. A casually designed or ambiguous approach can lead to misunderstandings and produce products that don't align with your expectations. It's important to avoid these ambiguities by ensuring precise and detailed design in order to achieve the desired outcomes in production.

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......
Castellated PCBs: Introduction and Design Requirements
With the rapid development of electronic technology, electronic products are moving towards miniaturization, portability, multi-functionality, high integration, and high reliability.Consequently, printed circuit boards (PCBs) are frequently designed to integrate pre-existing, off-the-shelf modules. For example, IoT Bluetooth modules or NB-IoT modules, which are indispensable communication modules, can be soldered onto PCBs just like chips. These carrier boards are characterized by their small size and......
Copper Balancing in PCBs: Achieving Optimal Performance and High Yields with JLCPCB
Key Takeaways Copper balancing strategically distributes copper across PCB layers to create uniform density, preventing warpage, uneven plating, inconsistent etching, and signal integrity issues. The ideal copper density target sits within the 40%–60% golden ratio, with mirrored layers maintaining density variation within 15%–20% per IPC-6012 standards. Copper thieving (dot patterns or crosshatch meshes) equalizes current density during electroplating without introducing parasitic capacitance on spars......
PCB Design : How to Resolve Short Circuit Defects Caused by HASL
Key Takeaways In high-density PCB designs, HASL frequently causes solder bridging and short circuits due to its uneven surface and molten solder flow, especially on fine-pitch and dense traces. The most effective solution is to switch to ENIG (Electroless Nickel Immersion Gold), which provides superior planarity, significantly reduces bridging risks, and improves assembly yield. By selecting ENIG for dense layouts, optimizing solder mask design, and running DFM checks, designers can effectively elimin......
