GESP TECH -TRUSTWORTHY ONE-STOP PCB SERVICES MINIMIZE RISKS WITH PRECISE DESIGN RULE CHECK SERVICES

Introduction

A design rule check(DRC) is a set of rules that a PCB circuit designer can use in schematic design. These DRCs ensure that the schematic meets all manufacturing tolerances. and dimensional tolerances set by the designer for the board. whether small-scale or large-scale, the design is bound to change. This is especially true when PCB processing is performed on CNC machines. As a service provider with extensive experience in PCB production. GESP believes that a manufacturer’s ability to manage these changes . directly affects the quality of their final product. So, it is best to account for possible variations by providing enough margin of error in the design.

ADVANTAGE OF DESGIN RULE CHECK (DRC)

BENEFITS-OF-DESIGN-FOR-TEST-1

PCB design is a very complex process. because there are thousands of connections and electrical components on a multilayer board. No matter how careful or skilled you are, there will be some errors in your design . when working with so many components. Often, you will become aware of these errors during the production. forcing you to make corrections that require time and are costly. Fortunately, you can take steps to prevent such errors early on. At the top of the list is to perform a design rule check (DRC).

TYPE OF DESGIN RULE CHECK (DRC)

For manufacturability, the layout of a design must adhere to a set of specified technology rules provided by the foundry. After the layout and physical connection are completed, an automatic program will evaluate each polygon in the design against these design principles and report any infractions. This entire procedure is known as Design Rule Checking (DRC). There are numerous design guidelines at various technology nodes, a few of which are listed here.

listed of Design Rule Check

  • Minimum width and spacing of metal
  • Minimum width and spacing of overholes
  • Thick line Via keep out Enclosure
  • End of line spacing
  • Minimum area
  • Over maximum stack level
  • Wide metal jogging
  • Unaligned over-the-hole lines
  • Different web spacing
  • Special notch spacing
  • Violation of shorts
  • Different mesh cut spacing
  • Less than minimum side length
