Printing carbon oil production capacity
Let's take a look at the production capacity of India Carbon Oil.
1. Carbon oil gap: Because of the good conductivity of carbon oil, the carbon oil on the finished board needs a certain gap to ensure no short circuit, usually requiring a minimum of 8 mil gap (HOZ bottom copper) and 12 mil gap ( 1-3OZ bottom copper), if the production of film can increase the gap, try to increase the gap of the finished product to ensure that there is no short circuit.
2. Minimum alignment tolerance of carbon oil: +/- 6mil
3. Size of carbon oil window and gap with copper PATTERN: Considering factors such as alignment tolerance and oil seepage, carbon oil is 6 mil (HOZ copper) and 8 mil (1-3 OZ copper) on one side of copper PAD. Do not expose copper. Correspondingly, the distance between the carbon window and the surrounding copper PATTERN also needs to be 6 mils (HOZ copper) and 8 mil (1-3OZ copper) to avoid the carbon oil covering the surrounding copper PATTERN, thus avoiding short circuits.
4. Carbon oil thickness: once screen printing carbon oil thickness: 0.3-1.0mil, once screen printing carbon oil thickness tolerance: +/-0.3mil; if the carbon oil thickness is more than 1.0mil, the second printing carbon oil is required. The second time, the carbon thickness of the printed ink is 1.0-2.0 mil, and the thickness tolerance is +/- 0.4 mil. The second printing carbon film is 3 mil smaller than the first screen printing carbon film, so two sets of tools are required on MI.
