Protect-A-Probe™
ADG Coating to Lessen/Eliminate Probe Cleaning

FEATURES

The Protect-A Probe™ ADG (Anti-Diffusion Gold) coating is designed to lessen or eliminate the need for probe cleaning by applying a proprietary, anti-diffusion gold coating onto the probe before assembly. This coating, once applied, acts like a "Teflon" barrier preventing solder and other debris from adhering to the probe tip, lessening (or eliminating) cleaning, which reduces downtime and provides increased throughput!

When used in HAST, HTOL or standard burn-in applications, this ADG coating can prevent the IC solder balls/bumps from "sticking" to the probe causing damage to the IC and/or socket. When used in test (including RF testing) applications, a probe that stays cleaner, longer, will yield more consistent contact resistance (CRes) readings over a longer period of time, thus saving time and money.

ADG coating has been tested in a socket with an IC which had SAC 405 balls on 0.35mm pitch for over 1500 hours at 150°C. No debris or IC or socket damage was noticed.

The ADG coating is now available for Aries' complete line of spring-probe, standard and custom Test and Burn-in Sockets as well as the complete line of spring-probe based RF Test sockets.

ADG Protect-A-Probe Test Plates

Two plates prepared for testing:

Plate #1 – a Cu base, plated with Nickel and Hard Gold
Plate #2 – a Cu Base, plated with Nickel and ADG

Both test plates were evenly coated with Sn and exposed to 155ºC for 24 hours and the quantity of Sn diffused into the surface measured.

Sn diffused into Plate #1 = 4.8mg ±0.5mg (Standard Gold)
Sn diffused into Plate #2 = 0.0mg ±0.5mg (ADG-coated)
