Many factories in Shenzhen have 100-level workshops, and many small factories also have 100-level workshops. However, due to the issue of product authorization, some factories do not have formal business licenses, so it is temporarily impossible to make statistics.
Environment is very important for the production and processing (bonding) of capacitive screen. Generally, medium-sized enterprises have several purification workshop at the same level, such as 10,000-level, 1,000-level and 100-level.
A Brief Introduction to Hundred-level purification workshop:
To put it simply, 100 purification workshop means that the dust particles suspended in the air per cubic meter of space in the workshop are less than 100PCS, so it is impossible to be clean. Of course, the industry is represented by relevant data, and the diameter of dust particles is also needed.
The smaller the purification workshop grade, the higher the cleanliness (that is, the less dust particles suspended in the air). Purification workshop has strict requirements on people's walking (no running inside), clothing and temperature and humidity. It is equipped with air conditioners, humidifiers, FFU and even large temperature and humidity control equipment to control the particle size of dust.
