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.
There are many intermediate techniques used in several stages that build on the schematic or netlist. These functions include things such as library development, signal integrity checks, stress analysis, thermal simulation and EMI checking. All this leads up to the generation of the gerber file. This is the most commonly used format used for transferring complete PCB images ready for manufacturing.
Designers must be able to work on complex solutions involving everything from digital and analog to RF circuits and mixed PCBs. The board can be designed as per specifications as a single or double sided board, or a multi-layered one. The size is also likely to vary, and so will other factors such as component quantities and pin densities.
There's also the question of deciding on the characteristics of the board. This refers to the method used to mount components and create the traces for the circuit. Surface-mount technology is the most popular technique used now for mounting components.
Using this surface-mount technique, the end caps are directly soldered now on the same side of the board. This new method has almost completely replaced the earlier through-hole boards. In these older boards, leads were inserted from one side of the board and soldered onto traces on the 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.
There may, in fact, be other PCB design services required even after delivery of the end product. Customers often need to do minor changes to the design right away and on an ongoing basis, and reorders are also on the cards. Designers are sometimes asked to reverse engineer the process, starting with gerber files. Coming up with a netlist or schematic from a gerber file helps the client rebuild the circuit to implement large-scale changes.
