When to put the brakes on PCB tracking routing

Tracking routing isn't all red, yellow, green - you know how a yellow light shows a dozen different things depending on the driver? It's more like how many elements can affect the trace. All of the following factors affect the possibility of short circuits during manufacture and operation:

Line width: Same as adjusting the width of the road, the width of the line will affect the size of the trend. Carrying an overload with you can bring a lot of trouble, just like registering a new business on a small road. Occasionally, the traces are narrowed before connecting to the pads, which can add resistance and associated heating and board damage. Reducing the width of the stalk is generally not a good idea.

Connections: Increasing the number of connections connected to a pad or node also increases the risk of short circuits. Branch traces may be closer to each other, with more corners to accumulate charge. More uneven solder paste, resulting in skewed components or solder bridges. You should carefully evaluate any net or autorouting output that requires many traces to be connected on a single pad.

Pad Size: Larger pads give you more headroom, but you should also consider the spacing between pads. This is where the solder bridge shorts out, so a larger gap makes the bridge harder to form

Uniform dimensions: Having the same pad and trace dimensions makes it easier to keep up with design and error rule checking speed, especially if you're dealing with multi-layer boards. Like a city permit office, rules can be annoying, especially when you have to fix a bunch of warnings, but they generally shield you from bigger problems. double sided pcb board

<Guanjiao: A sharp turn creates an orientation where the electric field potential builds up. While good fabrication can adapt to corners, once the board is running, functional results increase the risk of arcing and short circuits. Instead, stick to rounded corners with a large radius.
