Avoiding Ambiguities for Non-Standard PCB Shapes

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.
