CAD which stands for Computer Aided Designing was originally developed to ease the process of engineering product designs and drawings. Designing and drawing for engineering purposes has been around for centuries. Drawings have been used in construction, in civil developments and manufacturing industries since their early inception.
The importance of drawing for engineering, designing, and manufacturing processes has led to the development of CAD. But CAD is more than just a designing tool. Especially when it comes to the electronics industry.
A PCB, which is an abbreviation for Printed Circuit Boards, has many complex components and circuits embedded into a small piece of plastic like material. The leading manufacturers of PCBs, mjsdesigns.com, explains how CAD has evolved more than just a designing tool for the electronics industry.
Specialized Design Tools
For applications in electronics, specialized software packages are available in the market. These software programmes are known as ECAD or EDA. The difference between a typical CAD tool and ECAD is, ECAD has pre-programmed features to sort the development of an electronic component and can also combine components to design a gadget.
The ease of use and multi-platform accessibility allows the designer to review and check the designs anytime. The designs created are simultaneously backed up and can be shared with different users.
Eliminates The Need Of Physical Prototypes
Since CAD is able to perform testing on the design, it eliminates the need for physical prototypes. For example, in a PCB CAD layout, the software can check all the components of the circuit and correct their faults. The alignment and laying of different layers of PCB can be optimized precisely with the help of CAD.
It can perform all the logical functions as the original product is supposed to. These programmes are capable of testing, checking, and rectifying any fault in the design that can affect the performance of the product. Thus, reducing the financial and material losses as well.
The Design Can Be Directly Manufactured
With the help of CAM (Computer Aided Manufacturing), the designs can directly be converted into product. Since the electronics have complex designing aspects down to the sub-atomic levels, directly manufacturing the products from the designs can prove to be highly efficient. This results in higher production rates in lesser time.
Moreover, the integration of CAD and CAM also allows monitoring the production line while the manufacturing process is being carried out. Thus ensuring the product quality online.
Reduces Manual Errors
As already mentioned, the integration of manufacturing processes and the designs eliminate the need for any human intervention. Since human involvement is not necessary, it reduces the risk of manual errors.
Also, the software can run simulation programmes on the electronic components to ensure that there are no faults in the product. In fact, the faults due to designing can also be easily rectified with the help of designing tools.
Further Scope For CAD In The Industry
As the electronics have evolved from a gigantic size for a single transistor to thousands of them embedded onto a single microchip, an increase in the demand of CAD applications down the line is assured.
With the introduction of nanotechnology and increased demand in high-performance electronics, the applications for CAD in designing and product development has increased folds. And it is going to increase in the coming years.
