The carbon ink has strong adhesion, peeling resistance, and strong abrasion resistance, which can reach ≥ 1 million times, and the resistance change rate is ≤ 10%. The square resistance of conductive paste is relatively large compared to other metals. The square resistance of the current carbon oil board can generally be controlled at ≤ 20 ohms, but the cost is low with a high-performance cost ratio. The conductive paste is a crucial material for electronic component packaging, electrodes, and interconnection of electronic components. It mainly includes two types: burn-in conductive paste and curing conductive adhesive (conductive ink).
How big is the gap between the copper pad and the carbon oil window?
3. The size of the carbon oil window and the gap between the copper pattern: Due to the alignment tolerance and oil leakage and to ensure copper is not exposed, the carbon oil must be 6mil (HOZ bottom copper) or 8mil (1-3OZ bottom copper) larger than the copper pad on one side. Correspondingly, a gap of 6 mil (HOZ bottom copper) and 8 mil (1-3OZ bottom copper) between the carbon oil window and the surrounding copper pattern is required. This is to prevent carbon oil from covering the surrounding copper pattern, to avoid short circuits.

How does tattoo ink work?
The tattoo artist has to inject the ink solution into the right layer of the skin to achieve permanent results. Ink needs to reach the skin’s dermis layer, which is the thickest layer between the epidermis and hypodermis. The ink needs to get to the dermis because it does not shed itself as quickly as the epidermis. Every person has a fresh epidermis layer every three to four weeks, and if the ink does not penetrate past the epidermis, the tattoo will fade away within a matter of weeks.
Why is carrier important for tattoo design?
When selecting a tattoo design, most individuals are focused on the color of the ink. However, the carrier plays a strong role that is equally important to the success of the overall design.
