CDP Lines

Technic’s CDP-2000 is a precision electroplating machine designed for high accuracy controlled depth precious metal plating onto loose parts, typically for pins and sockets for the electronic connector industry. Considering that only a small area at the end of the part needs to be electroplated, tremendous savings can be realized when compared with conventional plating methods.

Parts may include:

  • Electrical connector pin and socket components
  • Spring plunger contacts
  • Terminal posts
  • Or any other pin/cylindrical shaped objects manufactured as single components

Key Design Features

  • Transport belts available with permanent inserts or removable cartridges depending on the volume and required flexibility.
  • Dual processing lanes can be configured with the same or two different component configurations. Common chemical reservoirs supply process cells in each lane.
  • Plating cells utilize precision fluid flow and level controls to produce controlled depth repeatability to within 0.5mm.
  • Menu driven computer reconfigurable anodes provide plating flexibility for a variety of part types including difficult to plate parts requiring high throw into internal recesses.
  • Contact roller connects cathode current to transport belt, providing noise-free low resistance electrical contact with minimal drag and no particle generation.
  • Plating cells utilize a synchronized backup conveyor, which provides pressure on each part through the cells for reliable cathode electrical connection in transport belt.

Features & Benefits

  • High, medium, or low volume production – Plated component throughput of 1000-20000 parts per hour
  • Rapid payback with up to 70% gold savings over conventional barrel plated parts
  • Unique plating cell and sparging design provides accurate and repeatable plating depth control and consistent part to part thickness uniformity
  • Plating cell eliminates the ‘brown ring’ at the demarcation line between controlled depth deposit and base deposit.

Load/Unload Options

Manual or fully automatic, in-line or off-line loading and unloading of parts is available. Automation is accomplished using various technologies including:

  • Vibratory bowl feeders
  • Inline conveyor
  • Scara robot
  • Cassette-to-cassette

Gold Savings Case Study

Data presented here is the summary data from an actual case study demonstrating Gold & Dollar savings achievable when using the CDP-2000 versus barrel plating of connector sockets and pins. Plating thickness profiles used for the calculation of savings are averages of a 20 piece sample size taken from a 200 part run for both the parts.

Gold Savings for Pin

  • 50m” overall barrel plate*
  • 1.2 gm/1000 parts
  • Selective plate + Au flash remainder
  • 0.54 gm/1000 parts
  • Gold savings of 0.66 gm/1000 parts, 55%
  • 660 gm or 21 troy oz of Au for 1 million pins
  • $16,800 at $800/troy oz Au

Gold Savings for Socket

  • 50m” overall barrel plate*
  • 2.16 gm/1000 parts
  • Selective plate + Au flash remainder
  • 0.69 gm/1000 parts
  • Gold savings of 1.47 gm/1000 parts, 68%
  • 1470 gm or 47 troy oz of Au for 1 million pins
  • $37,600 at $800/troy oz Au
