We produce electroplating steel ball which utilize in roll electroplating process for chip electronic components, such as chip capacitors, chip resistors, chip inductors, and so on. It also called nickel-plate steel ball, tinning steel ball, or small steel ball. Composition: The basical material of electric Steel Ball is carbon steel, then process 2 layers nickel-plate arround its surface. Its Chemical Composition show as below: Grade C (%) Si (%) Mn (%) S (%) P (%) Carbon steel 0.***1.*0 0.**1.2 0.**1.*0 < 0.*5 < 0.*5 Specifications: 1.∮0.3mm ~∮0.4mm, use in plating for type***2, or even more smaller chip componets. 2.∮0.5mm ~∮0.6mm, use in plating for type***3, ***5 etc chip components. 3.∮0.8mm ~∮1.0mm, use in plating for type***6, or other larger chip components. Divide into three categories according their surface: *****’s the normal carbon steel ***** doesn’t deal with any plating. This steel ball cann’t be used directly, because the iron oxide surface will destroy the plating chemical medicine. 2. It’s nickel-plating steel ***** ball can be used directly.Due to nickel price come down and its good conductivity, so this ball become more and more popular. 3. It’s tinning steel ***** ball can be used directly, too. Why the plating factory must use the Electroplating Steel Ball in the process of chip components electroplating ? In the process of the chip components electroplating, nickel-plate steel ball act as the conductor, its most important function is that can avoid the current add on the chip components directly, then prevent the chip component from being burned.
