Screen printing room carbon oil board process control
The technical control of screen printing room carbon oil board is actually simple and not simple. It is complicated and not complicated. Let's take a look at the following aspects:

The operator must wear gloves.
1. During the production operation, the technological parameters of each machine and equipment must be in accordance with the relevant operating instructions and must not be arbitrarily changed.
2. The machines and equipment must be clean and free of dust, garbage, oil, and other debris.
3. The screen printing speed and the speed of the ink return suction pressure are controlled in the optimal range. (Based on the printing effect as the inspection basis).
4. Wire mesh, scraper and carbon oil are selected according to the requirements of the engineering MI.
5. Before the use of carbon oil must be stirred evenly, using a viscometer to detect the viscosity within the required range, the ink promptly sealed after use.
6. Before printing, the oil, oxides, and other contaminants on the board surface must be cleaned. All carbon-filled carbon plates must be confirmed by the QA board before they can be officially produced.
7. In the process of screen printing, the operator must at least self-check 2PNL for each printed board, and in particular, increase the number of self-checks.                                                                                                                     8.Carbon Oil Drying Temperature 150°C 45 minutes.  Carbon oil hole drying temperature 150°C for 20 minutes, after
Carbon oil resistance measurement, carbon oil through hole resistance value should be less than 100 ohms.

9. carbon wire square resistance is less than 25Ω / mouth (carbon wire length ÷ carbon wire width × 25Ω), carbon oil filling holes Within 2 / 3 or more, according to The drawings of the engineering department and points required by the MI are tested.
10.The operator of the fascia board fills in the temperature amount of each time the board enters the furnace, and the operator shall notify the QA of the carbon resistance check and adhesion test after the furnace is cooled.
11.Each carbon oil screen used up to 2500 prints must be returned to the net room to re-shine the new screen.
