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.
At this point, it would be appropriate to note that the client is usually required to provide the designer with information about at least three basic aspects. One is the aforementioned schematic, although it may also be provided by the client as a netlist file. The netlist is simply a file that contains all the connectivity information for the design, along with descriptions of components used.
The client also has to provide the BOM (bill of materials) that lists all the components to be used and their footprints, although some designers also offer assistance with component footprint capture. Then there's also the board outline that must be provided. The outline, schematic/netlist and the BOM together constitute all the necessary information that will be used for designing the PCB.
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.
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.
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.
Apart from the schematic capture and subsequent board designing steps, the designer may also be called upon to evaluate existing designs, components and footprint captures. Sometimes they're also involved in prototype procurement, and may be asked to do availability checks and collect pricing information against the BOM.
As a matter of fact, PCB design services continue to be required even after the product is delivered. Customers frequently need to make changes, and reorders bring a lot more business. Reverse engineering is another service that needs a highly skilled designer. In this case, the designer is given the gerber file and must come up with the schematic or netlist, which the client can then use for making wide-ranging changes.
