Performance Characteristics
It has high dispersibility and good stability, and can be added the solution with 5X concentration
The carbon film is easy to remove and peels off in 5-7 seconds. It is suitable for the production of multi-layer soft board and black hole of blind hole board, without residual carbon
It is suitable for direct electroplating. After the black hole, it can be coated and developed for direct electroplating
It is especially suitable for hard board production, replacing PTH and conductive polymer. It only needs to make one black hole, saving water, electricity and labor
Treatment Effect
Comparison of hole climbing performance of production line - DTV
(left) DTV film of other black hole production line
(right) DTV film of Shangrong third generation black hole production line
Shangrong third-generation black hole DTV has 8 high and 7 low hole climbing capacity, and the copper layer around the hole has a large spreading area, reflecting the good dispersion and excellent conductivity of the third-generation black hole.
Multilayer plate and blind hole plate slicing
Shangrong third-generation black hole products, multi-layer soft board and blind hole board electroplating chips, because the carbon layer is easier to peel off from the surface of the copper layer, it is more suitable for the production of multi-layer soft board and blind hole board, and there will be no residual carbon.
