Jardine Xing has always adhered to the perfect integration of professionalism and quality as the concept, the establishment of a good enterprise system. The company has excellent industrial moisture-proof drying dehumidification technology, independent research and development and production of various specifications ofElectronic moisture-proof cabinets、Nitrogen cabinets, Constant temperature and humidity cabinets, ovens, rubber machines and other products. The following is an explanation for the high bad rate of dispensing in automatic dispensing machine:
In the information age, electronic chip packaging has been a major problem in the industry. In recent years, the skill of dispensing machine has developed rapidly, and there has been a breakthrough in precision. Automatic dispensing machine yield and bad rate has become a lot of people pay attention to the problem, the following we to analyze the automatic dispensing machine bad rate is caused by what reason?
Factor one, automatic dispensing machine dispensing amount is not reasonable
Generally speaking, we should follow a principle when dispensing any product, that is, the size of the amount of glue in the automatic dispensing machine does not exceed half the spacing between the solder joints, if more than this point of glue may cause an increase in the bad rate!
Factor two, control of dispensing pressure
Automatic dispensing machine dispensing when the pressure is greater, the greater the amount of dispensing, the smaller the dispensing pressure, the smaller the amount of dispensing, we should synthesize the glue characteristics, temperature, environment and other factors to set up reasonably!
Third, the choice of needle size of automatic dispensing machine
Generally speaking, the diameter of the needle of the automatic dispensing machine should be about half of the diameter of the dispensing volume, which is the most suitable needle size, otherwise it may cause the automatic dispensing machine out of the glue is too large or too small, increase the bad rate of the product!
Iv. control of Glue temperature
Epoxy resin glue storage environment should be around 0~5摄氏度, the use of temperature is around 23 degrees Celsius, in the use of glue we should let the glue and the surrounding environment better adapt to, to avoid the use of glue in the process of drawing problems!
Five, the viscosity of the glue
Automatic dispensing machine glue viscosity is large, dispensing machine dispensing small amount, glue viscosity is small, dispensing machine dispensing amount is small, automatic dispensing machine in the dispensing before we have to reasonable control of the glue viscosity, so as not to affect the normal dispensing work!
Vi. Avoiding Air entry
Automatic dispensing machine around the environment selection is very important, in the dispensing machine before, we need to place the dispensing machine in a dry, closed environment, to avoid air entry, dispensing machine appearance phenomenon, is also to reduce the rate of bad dispensing!
