Why PCB Design Preparation is Critical to PCB Success- Part 1
Printed Circuit Board Assemblies (PCB) manufacturing is a far more complex process that it used to be, with the increasing complexity and diminishing size required for many PCB assemblies. As electronic devices shrink due to demand for highly portable, light-weight products, the need for PCB designers to invest significant time in their PCB layouts will only increase.
To make this point, here are some things that can happen from faulty PCB design, often linked to not taking care to have a proper PCB layout at the onset of the manufacturing process:
- Products that fail to perform according to specified standards or design parameters
- Quality issues caused by poor or interrupted circuit flow, electromagnetic interference, track width, physical board interference, and other issues related to board structure.
- Functional issues related to components and circuit paths that conflict with other board elements.
In these and other cases, preparation plays a critical role in the functioning of the PCB Assembly. As PCB Designers take the time to prepare, these and other consideration should be given a thought:
- Sizing and placement of critical elements
- Minimum and maximum tolerances
- Electrical demands
- Possible impedance factors
- Creating templates for subsequent designs
- Establishing constraints to reduce potential errors
- Efficiency of the design process itself
Most PCB Assemblies are designed using a CAD process that may or may not translate into a fully functioning design. Care must be taken from the onset of the design to test and ensure that the design is realistic, applicable and fully able to function as designed.
With these things in mind, there are some practical things that PCB Designers can do to meet the demands of an effective PCB layout. These will be discussed in our next post.
