When you start searching for a PCB manufacturer, you will find a long list of companies offering different capabilities, price, delivery, and quality. You might find that a company provides exceptional quality and price for a 4 layer board, but they can’t deliver the quality you need for a more complex design. This could also work the other way – a PCB manufacturer with advanced capabilities might not offer competitive pricing for a 2 layer board.
To help you with your search, we have compiled this list of printed circuit board manufacturers and we have provided an overview of their capabilities and services.
