微孔填充及镀通孔:技术选择及解决方案
Miniaturization of electronics is setting demands for smaller and high density interconnects(HDI)for printed circuit boards and packaging. Functional reliabi-lity is highly dependent on the quality of direct metallization technology as well as the quality of filling microvias and plating through-holes.The demand for improved process performance has resulted in increased process complexity:several group of additives are used making process control almost impossible. Inaddition PPR technology has been applied as a solution,eventually in combination with additive stability through redox-protection of functional chemistry.A new technology approach,preserving simplicity and ensuring efficient process control,has been developed for simultaneous filling of microvias and excellent plating of through-holes.And the new concept has been tested and proven in industrial applications for panel as well as pattern plating. The new process is a drop-in process:It uses existing DC-power supplies and plating equipment. In addition,since process chemistry has been reduced to a minimum,bath life is increased and process quality is easily controlled.
