Laminate-This aspect establishes the life of the PCB. Therefore, it needs to be tested in a sharp and detailed manner. If the test is not carried out, it may cause problems with the final function of the ship. The tester focused on looking at the resistance of the laminate in order to force peeling or use heat.
With an increasing number of companies in China seeking to expand their customer base and compete in international markets, particularly the high-growth industries in the Asia Pacific and beyond, offering a complete range of Pcb assembly service in China will provide a vital edge over local competitors.
The copper plating tester analyzes the quality of copper in the laminate used to provide electrical conductivity. They examined the tensile energy and elongation in detail.
Solderability-The test here evaluates the wettability or outer lining welcome water solder education. This is indeed essential because it can determine the function of the PCB, mainly because it ensures that the component can be firmly connected to the circuit board.
Hygiene-This means your PCB's ability to withstand environmental variables such as humidity and corrosion. It includes evaluations before and after PCBS suffering from various environmentally friendly conditions.
Solderability: The solderability test of materials is essential for a powerful PCB because it ensures that the component can be firmly connected to the circuit board. The most commonly analyzed factor is wetting, or the surface acceptance of liquid solder.
Setup: Several PCBs are run in a wet setup, so the repeated evaluation of the PCB is the water absorption. In these types of tests, the PCB is weighed before and after it is placed in a humid environment, and any significant weight change will result in failure.
Electrically test PCB conductivity to minimize current leakage.
Hole wall surface quality-this is indeed another important inspection component to ensure that when the PCB enters the World Wide Web page, the starting wall area does not crack or delaminate. Analyze components in an environment with periodic and rapidly changing temperatures to understand their response to heat and stress.
