What are the hazards of PCB deformation? Can it be solved?
printed circuit board is usually represented by "PCB", not "PCB".
In the automatic surface mounting or inserting line, if the PCB board is not flat, it may cause inaccurate positioning, which may lead to the failure of components to be mounted or inserted on the board, and may even lead to equipment failure and damage.
If the PCB board after welding is deformed, it is difficult to cut the pin of the plug-in, and the operation difficulty of tin holding and other processes is improved. However, there will also be a lot of empty soldering, false soldering and other abnormalities associated with the patch, greatly improving the subsequent work load of board repair.
Finally, in the assembly process, the deformed PCB may cause serious problems to the production. For example, the PCB does not fit well with the housing. When assembling individual PCB, the efficiency may be only one tenth of that of other PCB, and the probability of subsequent defects has increased several times, which further aggravates the after-sales problems.
Therefore, with the development of the industry, more and more attention is paid to the deformation of PCB, and higher requirements are constantly put forward.
Some customers with high requirements for product reliability have begun to develop their own more stringent standards based on IPC standards to ensure that their products have more competitive advantages. During the PCB production process of Circuit, they are committed to delivering products with high reliability and high standards for customers.
However, PCB board is composed of copper foil, resin, glass fiber cloth and other materials. There are differences between the physical and chEMIcal properties of various materials. During the processing, the PCB board will undergo chemical solution, cold and hot changes, and deformation is inevitable. The improvement of deformation is an industrial problem, which cannot be solved overnight, but it can be improved step by step.
