Coating machine in the design of cent what should notice?

A good coating machine, from the design at the beginning is expected late may attack all the trouble, and in the design of cent can prevent these problems, the vacuum leak detection work continuously is a big flaw in the industry, a lot of people don't get treatment, how to do? From a design standpoint say first!
First of all, in accordance with the process of equipment request to certain vacuum machine can accept the largest leak rate. And follow the probability of each component's biggest floor rate. Then based on the equipment best to resolution that allows the leakage rate of sealing and cohesion, and vacuum coating machine as one of guiding and modulation of the criterion, equipment parts maximum allowable leakage rate, the demand is thought to accepted by pressurized leak detection of pressure and structural strength, in the structure design of cent, in container or system must keep leak detector using excuses, such can lunch bento equipment in the assembly, the debugging process, leakage, if any, have ever found it must turn off the power supply maintenance, in parts design, to prevent possible interference to the possibility of leak detection work, due to the leakage of cent, all needs to use the machine parts, if there was something wrong with a component, and leak detection work can't stop! You must pay attention to this problem!
