Why PCB testing is needed

Testing is a major requirement in the PCB assembly industry. If you do not test properly, it means that the entire printed circuit board will be defective in various ways.

Testing avoids errors, and problems that may be overlooked during the production phase. It has the potential to cause field failures and defects. In order to reduce the chance of failure and maintain customer satisfaction, it is important to conduct PCBs through testing procedures. Please note that the manufacturer's Implementation is to ensure that the PCB and components are fully functional. Here are some of the advantages of PCB testing;

Vulnerability Identification: The main advantage of PCB testing is that it helps to identify problems in the PCB. If the problem is with manufacturability, functionality, or elsewhere, PCB testing is able to identify what a PCB design is so that designers can adjust.

save Time: PCB testing as an early stage helps save time in the long run. Testing also allows designers to identify major issues during the prototyping stage. During testing, enables designers to quickly and easily govern proposed The root cause of each problem. It also helps to decide early whether to make adjustments so they can continue production at a faster rate and manage production time.

lower Cost: PCB testing plays a key role in reducing wasteful production of defective products by applying prototypes and small-scale assembly to test products. When testing is done early in the design process, it helps designers prevent wasteful full-scale assembly of the PCB. It also helps ensure that the design is as flawless as possible before it goes into production. This step helps reduce production costs significantly.

What is being tested

laminate - This component determines the lifespan of the PCB. It therefore needs to be tested keenly and in detail. Failure to test may cause problems with the final functionality of the ship. Testers focus on viewing the laminate's Resistors for forced stripping or use of heat.

plating Copper-testers test the quality of copper used in laminates to provide electrical conductivity. They analyze tensile strength and elongation in detail.

Solderability - This test does analyze the wettability or how well the surface accepts liquid solder. This is essential as it determines the functionality of the PCB as it ensures that components can be securely attached to the board.

clean Degrees – This means the ability of the PCB to resist environmental factors such as humidity and corrosion. It includes analyzing the PCBS before and after experiencing various environmental conditions.

Yes Solderability: Solderability testing of materials is critical to a functional PCB as it ensures that components can be securely attached to the board. The most frequently analyzed factor is wetting, or the surface that accepts liquid solder degree.

environment : Many PCBs operate in wet environments, so a common test for PCBs is water absorption. In these types of tests, the PCB is weighed before and after being placed in the wet environment, and any significant weight change will result in a failure .

Electrical - Tests PCB conductivity to minimize current leakage.

hole Wall Quality – This is another very important test component to ensure that the hole walls do not crack or delaminate when the PCB enters the field. This component is analyzed in environments with cycling and rapidly changing temperatures to see How they respond to thermal stress
