Ultra-clean bench has a lot of optical industry, quite a lot of lens contamination is the cause of the change under the protection of the mirror operation is not standardised, resulting in inhalation or blowing into the dust caused by the protection of the mirror contamination. Cutting in the insertion and extraction of the lower protection draw too often will also increase the risk of contamination of the middle protection mirror. In maintenance, insertion and removal of optical fibres and inspection lenses often cause contamination of the upper protective mirror, optical path cavity. Therefore, the replacement of protective lenses in the field of whether to comply with the norms and whether the correct use of class 100 purification workbench is quite critical to reduce the failure rate of the cutting head. According to Dersion editorial understanding of the common problems are as follows.
What should we pay attention to when using a Class 100 purification bench on site?) There is a Class 100 purification workbench on site, but the storage environment is not set up in a special area. Often observed that there are debris on the workbench; or shared with office areas and storage areas. Clean bench has not been used before the heavy source of contamination.
2) There is no filter maintenance and replacement programme. Even if the use of less frequent filter is no annual update plan. Filter operation with disease, the clean effect is greatly reduced.
3) Class 100 purification workbench before the use of the lack of preparatory work. Generally need to start at least half an hour or more in advance, if the site air environment is very dirty it is recommended that the first do not open the air supply system of the bench, the internal side walls of the bench up and down the surface with alcohol wipes clean.
4) Operation of nearby supporting facilities or heavy-duty machine types are not suspended. Need to turn off the fan, exhaust system to minimise air flow.
5) Temporary alternatives bring new risks of contamination. Some users do not have a class 100 purification workbench but with a large clean plastic bag set up to operate, the problem of doing so is:.
The existence of a fluke. As a result of not having a clean environment, it is likely to skip checking the interface cavity and fibre optic connector surface cleanliness of this critical step. 2 cross-pollution: the cutting head surface has a large amount of metal dust, contact with the plastic bag cross-pollution, thereby contaminating the fibre optic head and then contaminate the cutting head lens plastic bag cleanliness itself can not be guaranteed.
6) insufficient number of class 100 purification workbench or after-sales personnel quality awareness is weak. Workbench in a region with a number of customers. Normally placed in the office, the volume is large, not easy to transport, sometimes in a hurry lazy to move around!
7 Some customers use sponge-tipped swabs, and we have found that these swabs tend to leave a mark. The white mark under violet light affects the detection of dust. Not recommended. We recommend purchasing branded dust free cloths or fibre swabs. dust cloth or fibre swabs.
