PCBs (Printed circuit boards), are the dynamic forces forming the core of each and everything that we use ordinarily and are the driving forces behind almost everything we use today—smart phones, control panels for industrial machines, the display screens at fast food restaurants. When a PCB fails or fails to function, it disrupts both our personal and business lives tremendously.
The reasons of PCB failure can be commonly be associated to two factors: performance problems from environmental stresses, or performance problems originating from the design and manufacturing stage of the board’s production. Sometimes these failures happen after years and years of use, and sometimes the issues have been accidentally built into the board during its production, setting it up to fail even prior to its first use. Thankfully, due to the physical nature of the PCB, most issues are repairable.
One factors is Manufacturing Problems
Human error is the root of all printed circuit board manufacturing problems. From misinterpreting a diagram to wrongly labeling a component, there is an unending list of issues that can sprout at any given point in the design and manufacturing phases of PCB development.
Here’s a quick overview of some of some common and ordinary PCB manufacturing problems: components installed incorrectly or incorrectly placed; Improper soldering resulting in weak solder joints;
Unsuitable thickness of the board eventually causing it to bend or break;
Meager padding of traces leading to a voltage sweep, can be a probable cause of a burnt board;
Traces and pathways unintentionally placed very closely to one another, causing short circuit;
Improper connection between the layers of board contributing to unproductive performance;
Another factor is Environmental Problems
Environmental problems occur when a printed circuit board is exposed to elements or situations that affect its performance. Variables like temperature, dirt and debris, and moisture are the most common performance hinderers, but accidental impacts (dropping, electrostatic discharge, crushing, etc) or power overloads from lightning strikes or power surges can also be severely detrimental to your circuit board. Not even the most expertly crafted circuit board stands a chance against an electrical fire! Elements like dirt will degrade your board in a gradual manner, corroding it and reducing its overall lifespan. High environmental temperatures, like those found on some manufacturing floors, will also degrade components.
Some of these issues (like burned out components) are easily spotted, but if your board is failing and the problem is not easily identified, it needs to be tested with diagnostic equipment to pinpoint the issue. Your repair technician can do this for you.
