auto dry cabinet for electronic component

1. The problem leaded by unappropriate choosing and using the auto dry box
        The damp air would enter into the IC through the sealed material and lead the internal electric catec dry cabinet circuit oxidize and decay, and the highly degree temperature within the welding process would make the damp air inside the IC inflate and create pressure, as a result that the plastics is taking off from the chip or the inner part, the chip is damaged, the internal crack and the crack extend to the component's surface is coming out, even the component are damaged and the articles constructed by them are discard. The more important is that the unseen and latent blemish conceals in the product and affects its credibility. catec dry cabinet Other IC electronics component also exists this kind of problem leaded by damp mostly.
         Because the auto dry box at normal temperature belongs to a new product, general customer does not understand it and is hard to choose an accommodate one but is easily induced by the superficial phenomenon such as price or appearance. In fact, many customers have already been not satisfied with the product after purchase it. The problems are concentrated as following:

     (1) The dehumidifying time is too long. It would take 8 to 12 hours or 3 to 5 days, even 10 days to half a month to lower the inside humidity from RH70-80% to RH10%. Even more, some products catec dry cabinet can't lower the inside humidity down.
     (2) It is very inconvenient to customer that it should take a long time to lower the humidity down to RH10% again when open the door for taking or placing articles at the same time the damp air enters the box after the inside humidity is lowered down to RH10%. Because the auto dry box can't start to dehumidify immediately but should prepare for more than 2 hours and goes to preparing stage again after dehumidifying for a little time and thus repeats catec dry cabinet again and again. For this reason, some customers have to adjust the production to adapt the rhythm of the auto dry box, or only put the articles seldom used into the auto dry box, or purchase many dry boxes to solve this problem. But for the customers who want to take the auto dry box as tools, it is unable to attain the purpose.
     (3) The product's life and dependability. Some products don't dehumidify after they has only  catec dry cabinet used for short time as a few months or 2 to 3 years. But some products still work normally after they are already used for more than 10 years.
     (4) The problem of anti- static electricity. Some products have no measures for anti-static electricity and the IC is damaged by static electricity.
According to the above-mentioned problem, it is necessary to carry on analysis to the structure of auto dry box at normal temperature and provide science standard for catec dry cabinet the costumers to choose a fit product.
