Precision Electroformed Components

Precision electroforming is an additive process in which 2D and 3D micro structures are formed by electrochemically depositing metal into a precisely formed photo-resist mold. Such structures can include:

• Micro nozzles
• Microstructures
• Slits
• Micro screen/mesh
• Discs
• Embossing tools

Typically, the physical characteristics of micro structures are defined by their x,y,z, plane dimensional relationships. The x and y plane features (rectangles, spirals and virtually any geometric shape) are defined and controlled by the photo-resist mold.  Using precision electroforming, the minimum x,y feature size can be as small as 0.001mm.

The z plane dimensions are defined and controlled by the aspect ratio capability of the photo-resist mold material. Aspect ratio is defined as the maximum z value divided by the minimum feature size, x or y. Maximum possible aspect ratio values can range from 5:1 to 10:1, depending on the mold material and specific structural dimensions.

Precision electroforming provides the capability to create complex, multi-level structures and commonly uses materials such as:

• Nickel cobalt
• Pure gold
• Hard gold
• Copper
• Nickel

The process also can accommodate:

• Platinum
• Palladium
• Rhodium
• Magnetic nickel/iron
