Conductive Diamond Plating Process for Probes and Interconnects
Closup of GPCD Gigaprobes(tm) tip
DVT Solutions LLC is partnering with Giga Connections inc. to apply Gold Plated Conductive Diamond (GPCD) particles to the GigaProbes probe tips. This forms a superior, multi-point diamond connection system on the rough surface that can pierce any contaminants on either the DUT leads or test contacts. The resulting contact resistance is fewer than 5 milliohms with no measurable inductance or capacitance after thousands of mate/demate cycles. This controlled impedance material is electrically invisible, requires as little as 10-15 grams contact force, and resists oil and dirt contaminates. Conductive Diamond Plating has been used in military systems, including super computers and satellites, while meeting all military environmental specifications. When used as contacts on interposers, The GPCD enables 10 to 40 Gbp/s devices to perform the same or better within RF test socket, CPU socket applications than if they were soldered directly to the board, thereby opening opportunities for a new lead-free interconnect technology

Giga Connections Inc. 40 GHz interconnects technology deposits 1000’s of Very Sharp, Non-Oxidizing, and Conductive Gold Plated Diamonds on surfaces to be connected. This Creates a 40 GHz Board to Board Connection.
Highly reliable connections:>100,000 mate/de-mate cycles without measurable degradation in signal integrity.
Small pitch: Plated contact pad size of 5um (4 mil pitch) can be achieved
No scrubbing necessary:Easily breaks though surface oxide; creating a temporary or permanent connection as good as solder
Low mating force required: Decreases necessary minimum force to make low-resistive contact
Below are products where GPCD has been used to improve the performance over standard gold on gold, Delphi Gold Dot or any spring contact interconnects.
