With the development of science and technology, many electronic products are developing in the direction of small and precise, making the size of many SMD components smaller and smaller, not only the requirements of the processing environment are constantly improving, but also the SMT processing technology has been improved. high demands. In order to do a good job in PCBA processing, the SMT chip processing factory needs to do at least the following three points.
First, when the SMT processing process is carried out, everyone knows that solder paste needs to be used. For the solder paste just purchased, if it is not used immediately, it must be stored in an environment of 5-10 degrees. In order not to affect the use of the solder paste, it must not be placed in a sub-zero environment.
Second, when the SMT process is in the placement process, the placement machine equipment must be checked frequently. If the equipment is aging, or some parts are damaged, in order to ensure that the patch will not be skewed, there will be high In the case of throwing materials, the equipment must be repaired or replaced with a new one. Only in this way can production costs be reduced and production efficiency be improved.
Third, when carrying out the SMT process, if you want to ensure the quality ofPCB board welding, you must always pay attention to whether the setting of the process parameters of reflow soldering is very reasonable. If there is a problem with the parameter settings, the quality of PCB board welding will also be cannot be guaranteed. So typically, the furnace temperature must be tested twice a day, with a minimum of one. Only by continuously improving the temperature curve and setting the temperature curve of the welded products can the quality of the processed products be guaranteed.
The above is an introduction to the precautions of a good SMT chip processing factory. I hope it can help everyone. At the same time, if you want to know more about SMT chip processing information, you can send email to lisa.xu@pcb-hero.com
