PCB circuit board design is an important step before PCB production. Once it is not well controlled, it will affect the subsequent production, and then affect the quality and performance of the product. So, what are the methods for successful PCB circuit board design?
  Method 1: Pay attention to the research of manufacturing methods and the chemical treatment process of the manufacturer

  There are many engineers who really don’t know the steps and chemical processes involved in generating PCBs from their design files, leading to novice designers making more complicated design choices that are not necessary.
  Method 2: Refer to the complete schematic diagram

  Schematic diagram is a visual description of a circuit, which can communicate information at many levels. When designing the PCB layout, having a schematic diagram used as a golden reference can make the work easier; use symbols to complete the connection; when dealing with the routing challenge, it is not necessary to think about the connection at the same time.
  Method 3: Use but don’t rely on auto-router

  Most professional PCB CAD tools have automatic routers. In order to give full play to their role, the router parameters must be carefully and thoughtfully set for each task, and even each module in a single PCB design must be set separately. There is no basic general default setting suitable for any occasion.
  Method 4: Circuit board geometry and current

  Most people who are engaged in electronic design know that, just like a river walking along a river, electrons may encounter throat points and bottlenecks. PCB designers occasionally produce similar electrical throat points in their PCB designs. For example: use a 90-degree bend where two quick 45s can be used to form an angle; the bend is greater than 90 degrees to form a zigzag shape.
  Method 5: Solve the fragmentation problem

   Fragmentation is a manufacturing problem, which can be best managed by correct circuit board design. When designing the PCB layout, it is best to avoid leaving a very narrow copper area. This area is usually caused when copper is applied at the intersection of the wire and the pad gap. Set the minimum width of the copper sheet to exceed the minimum allowed by the manufacturer, and your design should have no problems in this regard.
  Trick 6: Follow DRC

  Most design teams will eventually establish a set of design rules aimed at: standardizing bare board construction costs, maximizing yield; assembling, inspecting, and testing as consistently as possible.
  Trick 7: Know the foundry you are using

A good foundry will provide some helpful help and suggestions before you place an order, including how to improve your design to reduce design iterations, reduce problems encountered during final debugging on the test bench, and improve the yield of circuit boards .
  The above is the successful method of PCB circuit board design explained by senior engineers. I hope it will help you.
