PCB design services require skilled designers who know how to come up with an optimum physical layout for a printed circuit board. They use cutting-edge CAD tools and other PCB design software that helps them create all kinds of board designs. No matter what sort of board and layout is required to be made, it's always going to be a multi-stage designing process starting with schematic capture.
Designers typically require that clients should provide basic information regarding three key matters. The most important of them is the schematic, but it may alternatively be in the form of a netlist file. This is a file containing connectivity details and component descriptions.
The BOM or bill of materials is another key requirement which contains a listing of all the components to be used and their footprints. Some designers offer to do the component footprint capture process too. All this and the board outline together provide the designer with everything needed for getting started with the design process.
Designers start with the netlist or schematic and use techniques such as library development, signal integrity checks, thermal simulation, stress analysis, EMI checking, etc. The series of intermediate steps lead to the development of a file in the gerber format. This is the final end product that designers hand over as a complete PCB image that is directly used in the manufacturing process.
Electrical and electronics circuit designers are expected to be able to work with and create complex designs for digital, analog, RF and mixed PCBs. The boards themselves may be single or double sided or multi-layered. They can be designed to match the customer's needs in different sizes with varying pin densities and component quantities.
The designer also has to decide the board characteristics. This is the method that must be used for mounting components and creating circuit traces. The most popular technique that is now in use is called surface-mount technology.
Under this method, end caps will be soldered on the same side of the board as the component itself. This is a huge improvement over an earlier system that made use of through-hole boards. These older boards required the leads to be inserted from one side and soldered on the traces on the board's other side.
In addition to designing new boards, PCB designers are often called upon to perform other tasks. For instance, one common service is an evaluation of an existing design, its components and the footprint captures. They may also be asked to help out with procuring prototypes, check for availability and price information against the bill of materials.
Certain PCB design services are required even after the client receives the finished product. Customers may seek changes to the design immediately or in future, and reorders are quite common. It works the other way around too, with designers asked to reverse engineer gerber files or film artwork into a netlist format or schematic. This is often required when complex circuits require heavy modifications at the most basic level.
