How PCB Design Affects the Performance of a Device

To have quality machines and devices means they must be made with quality components as well. Thus, devices must be designed for reliability. Otherwise, they will be rendered useless or obsolete in a short span of time. A device can be reliable for two things: one, it lasts; and two, it can carry out what it was originally meant to do. Suppose a mobile phone has a lot of glitches and cannot be used for sending messages, then what use does it have for people?

How a device performs also has something to do with how it was manufactured and design. Printed-circuit board (PCB) fabrication figures a lot in this aspect. When a design is right, it will offer the following:

Thermal Reliability

PCBCan the PCB conduct away heat? If it does not, it might result to problems and failure. PCB fabrication and design should prioritize thermal reliability so that the device does not heat up and conk out. Hence, the PCB board must be able to remove heat through convection and keep the components of the device cool and dust-free.

Electrical Reliability

The PCB layout software must determine the noise in narrow traces, insufficient current-return paths, and cutouts in ground planes. When this noise has been blocked properly, interference and other technical disruptions will be prevented. If you are designing your own PCB, make sure that the signal delivery has its own return-path, and that this return-path must be parallel with the signal line. Any break in ground planes or power will cause disruptions, and possibly, major problems.

Thermomechanical Reliability

An inflexible solder will crack and fail. This happens when the size of the PCB solder is not aligned with the leads of the package. Moreover, there must be a pattern created beforehand to ensure that the solder deposited to the PCB is of the right quantity or size. Keep in mind that thicker PCB boards are less flexible and may cause damage to solder joints. In contrast, a thinner PCB board bends more easily and lessens the stress on the solder joint.

Mechanical Reliability

Similar to thermomechanical reliability, mechanical ability accounts for the solder joint attached to the PCB board. When a solder joint becomes too stressed by bending, it can lead to cracks and leakage. Another cause of solder joint stress is shock damage, wherein vibrations or slight tremors pass through the PCB. One way to reduce solder joint stress is to use frames or plates that even out the distribution of shock waves.

At the same time, PCB mount connectors may improve the reliability of a device. These d-subminiature and standard-density mount connectors have been found to improve reliability and at such low prices. If you are thinking of creating your own PCB design, then you might want to get samples of such connectors to avoid any glitches in the device.

Clearly, PCB fabrication and design has a huge impact on device performance. Thus, it is crucial for engineers and other PCB developers or creators to use standard materials. When done properly, devices would also work in their best capacity. Any problem with a device is attributed to its internal machinations, and must be addressed preemptively.

Fortunately, there are tools that facilitate PCB fabrication and design. Multisim 7 simulation and Multicap 7 schematic capture tools improve and accelerate PCB board design. With these two, schematic entry tasks are reduced, information can be stored in a special database, and analysis is faster and better. Parts are also easily found and placed. Should developers and engineers lack these tools, they can always rely on other strategies to ensure that their PCBs will deliver the task it was intended to do.
