Printed circuit boards are considered to be one of the most important elements of electronic devices as PCBs must perform precisely to make the electronic device work with accuracy and efficiency. Printed circuit boards direct and regulate the transition of electronic current through the laminated sheets and etched copper pathways, which in turn allow the electronic devices to operate accurately. The necessity of PCB testing is evident by the fact that even the slightest of fault or error in any of the PCB components can cause to major quality issue in the device.
Importance and Relevance of PCB testing
PCB testing can be defined as the final step of the manufacturing process wherein the PCBs are tested against any manufacturing, operational or functional defects, errors or loopholes. It is hence very crucial for a customer to choose a PCB manufacturing company that provides an extensive range of testing and inspection services that will ensure highest quality and efficiency of the PCB sets.
PCB designs can be simple or complex, rigid or flexible, single-sided or double-sided, depending upon the kind of operation and type of application in varied industrial sectors. Immaculate PCB testing and inspection process is crucial to ensure that the final products would work with efficiency, reliability and high-quality on introduction to the market. Apt and complete PCB testing process aims at delivering high quality products with no loopholes, reducing net fabrication costs and increasing customers’ business revenues.
In other cases, PCB testing is capable to discover certain major latent quality and performance issues in PCB sets, the production and market introduction of which can ruin the brand name and image.
What are the PCB components that require proper testing?
There are certain complex electrical elements that a PCB consists of, which include resistors, diodes, capacitors, fuses and transistors. It is important for a PCB to be tested to make sure that each of these components is working efficiently and without any irregularity.
Resistors: These are tiny electronic elements in the PCBs with two terminals that help in transmitting electric current, producing voltage.
Capacitors: This element store energy in the form of electrostatic field and is made of an insulating material held between 2 conductive plates.
Diodes: This device makes the electric current flow in one direction and is made of semi-conductive material placed between 2 terminals
