One pitfall that you absolutely must avoid is making a design, that is impossible or difficult to produce. You can often end up focusing too much on material selection, structure, and components, that you forget to think about the end product and the production hereof.
Start by setting up your design rules in the program you are using. Here you can, for example, set up rules on how close the various components can be placed. This way you ensure that your design rules help achieve the intended result.
Design in a way that allows mass production
It is crucial to get your PCB designed in a way that allows more manufacturers to be able to produce it. It is also a question of the cost price of the end product. If multiple factories can carry out the production, the price is lower. If, on the other hand, only one or two factories can do it, it can often be too expensive or too risky to do. Therefore, spend some time considering how your design will be produced after development.
Also, keep in mind that the more complex a PCB becomes, the more expensive it will be to produce – and that is something you want to avoid. It is all about making it as simple as possible.
There are many PCB manufactures out there, and they all have varying requirements for the items they produce. For example, some factories can only make transistor radios, and are unable to manufacture fine technology. This requires specialist manufacturers who can handle the more complex products.
The standard can affect production
Another factor that can influence if it is possible to produce the PCB, is if you comply with requirements and standards, that was mentioned in a previous blog post. If you follow the IPC standard correctly, you can be sure that the PCB can be produced.
If you do not comply with the applicable requirements and standards, production errors may occur. For example, if 10% fails, it may be because you have not complied with the standards.
To avoid this, you must ensure throughout the entire process – and before it starts – that the structure, material choice and thickness is correctly outlined. If you do not define it properly, the result may be, that the PCB cannot be produced.
