Defects in PCB assembly and how can they be prevented?

In today’s world, printed circuit boards or PCBs have become an integral part of every advanced electronic application. Even though this electronic equipment may have different needs and h and purposes, they will all need error-free and performance-driven PCBs. PCBs have also become a crucial part of mission-critical applications like in the case of the military, defense, and medical where people‘s lives may be at stake. Therefore, it is important that during manufacturing, the PCBs are perfect. With bulk production, it is impossible to identify if the manufacturing is going wrong somewhere. Therefore, the PCB manufacturers employ various inspection and testing methods during the designing and manufacturing steps themselves.

They have electrical equipment pertaining to all kinds of testing and inspection systems which will ensure a smooth and flawless production.

PCBs are not only a part of the big electrical devices. They are also part of small electrical devices like digital thermometers. Therefore, a malfunction in the PCB can lead to malfunction in the device, both big and small. Here are a few common defects found in the case of PCBs

Missing electrical components

• Misalignment of the component
• Wrong orientation
• Opens and shorts
• Component misalignment
• Inconsistent soldering and many more

PCBs in smart thermometers

As I previously mentioned, PCBs are not only a part of high-end electrical equipment; they are also part of small electrical equipment like digital thermometers and temperature indication systems. Smart thermometer works on the principle of sending details of the temperature to the user’s phone. The user can see a history of their temperature readings. There is an option where the user can consolidate this information to check their overall temperature map. This way, the user will know when the high spots of temperatures occurred, and this information can be used to identify and diagnose diseases.

Smart thermometers contain PCBs in their circuit boards. These thermometers will not be able to function without PCB. PCB can be considered as the brain of the thermometer. PCB is responsible for recording, analyzing, and presenting the data to the user. PCB is also responsible for any kind of consolidation that occurs on the user demand.

If there is any defect in the manufacture of this PCB component, the thermometer will remain defective. Clearing the defect once the entire unit has been manufactured becomes very difficult. 

Therefore, companies emphasize on finding potential defects during the manufacturing process so that they can be cleared and the perfect product can be released in the market. With the outbreak of COVID-19, it has become imperative that everyone is able to have access to a thermometer. This has given rise to these smart thermometers.
