Finding a PCB manufacturer could prove to be a time-consuming and risky task. A web search returns many search results with no easy way to compare the various PCB companies.
When choosing a PCB manufacturer, there are a number of factors to consider such as quality, capabilities, customer service, price, customer satisfaction, and trustworthiness.
The good news is that we have done a lot of the research and analysis for you.
Here is our list of the top 10 PCB manufacturers

Aspect Ratio
The Aspect Ratio is defined as the scale of board thickness compared to the diameter of the drilled via. If you have a board with a 0.24″ thickness and a via with a 0.02″ diameter, the aspect ratio is 12:1. The higher this ratio, the increased plating that will be around a via compared to inside the via.
