    Who knew electroplating could look so awesome? The contrast between the copper metal and the solution looks pretty cool.

    This is what the copper looks like when I get it from my supplier. I need to buff this to a mirror finish without any marks or scratches before I can electroplate it with silver.

Two major types of copper foil are used for FCCL–electrolytic copper foil and rolled copper foil. Electrolytic copper foil is typically 18 or 12 microns in thickness, and rolled copper foil 18 microns thick. Generally, rolled copper foils demonstrate flexural properties superior to those of electrolytic copper foil. In recent years, flexural properties of electrolytic copper foil have been much improved and these foils are being increasingly used for optical pickup applications. This article describes a new electrolytic copper plating technology which is an essential step in the manufacturing process of FPCs. In general, FPC is manufactured with a flexible copper clad laminate (FCCL) or one of many combinations. FCCL may be broadly grouped into the following four types: 1) material made from single polyimide and copper clad sheets connected with epoxy adhesive. FPCs fall into three broad categories: single-sided flexible printed wiring boards, double-sided flexible printed wiring boards and multilayer flexible printed boards. HDD applications, in particular, require high flexibility and reliability, so rolled copper foils dominate this segment. and 4) material made by coating polyimide varnish on copper foil (casting) followed by a curing step. This new electrolytic copper plating technology improves the manufacturing process and realizes higher functionality. FPC Materials Polyimide is a crucial material which provides key features to FPCs and is used in almost all FPCs. Both types of copper foils are moving to thinner dimensions. Application of FPC FPCs are employed in a wide variety of applications due to the nature of their characteristics. However, multilayer FPCs only represent approximately 3 to 4% of the total FPC production by finished board area base. FPC Manufacturing Process As mentioned previously, FPCs fall into three broad categories. Single sided and double sided FPCs are widely employed for personal computers, optical pickup (OPU), HDD and cell phones. Flexible printed circuit boards (FPCs) are applied to various electronic devices due to their mechanical characteristics and are indispensable to electronic devices requiring system miniaturization, weight reduction and multi-functionality. In particular, multilayer FPCs have a wide variety manufacturing processes based on the specifics of desired structures and performance characteristics. Examples of applications for FPCs include cell-phone liquid crystal display enclosure, hinge parts, keypad, battery enclosure and interface components. single sided, double sided and multilayer. Each type of FPC has a series of required manufacturing process steps, examples of which are provided below. FPCs are also used in optical pickup and device interfaces inside hard disk drives, digital still cameras and digital camcorders.

electroplating copper?

Jan 16, 2009 by nyahhh | Posted in Engineering

i want to electroplate a metal thing with copper, which, as we all know, can be done by any high school chemistry student -- put the metallic object to be electroplated and a chunk of copper in a strong CuSO4 (aq) bath and apply atleast (3V was it?) of


I think it depends on what you need it for, how thick you need the Cu layer. But yeah you can use a solution mixture of sulfuric acid and hydrochloric acid diluted in DI water. Electronics grade Cu is also available in order to have a high purity Cu layer.(Note

While doing electroplating of Copper as a project I found the Cathode is depositing with a Black material.Why?

Oct 05, 2007 by kuriaksabu | Posted in Chemistry

I used copper sulphate solution as electrolyte and then tried with Sodium chloride and dilute acids .All cases in place of copper I found black material is depositing on cathode.any one suggest a good electrolyte for copper plating?


Well, I do not quite understand what you did. What do you mean "then tried with Sodium chloride and dilute acids"? Please put forward details. anyway, since the reduction potential of C++ is greater than H+, even if you simply put a piece
