The effect of 2-Mercaptobenzothiazole on laser-assisted electroless copper plating
Effect of 2-Mercaptobenzothiazole(2-MBT)on laser-assisted electroless copper plating,using formaldehyde as reducing agent as well as ethylenediaminetetraacetic acid(EDTA)and ethylenediaminetetrapropionic acid(EDTP)as complexing agents,has been investigated.The surface morphology,roughness,and crystallinity of copper coating depend on 2-MBT concentration.The plating rate enhances significantly with the increase of 2-MBT contents.Accelerating mechanism of electroless copper plating has been studied by means of Tafel plots and linear sweep voltammetry.It is found that the appropriate amount of 2-MBT can improve the quality of copper coatings and accelerate the electroless copper plating process due to the promotion of controlling step,as 2-MBT additions can form new electrostatic forces resulting in the decrease of absorption of or and then make controlling step occur more easily.
