Frequently Asked Questions
What contact material and finish does the IC51-0804-956-2 use, and why does it matter for test reliability?
The IC51-0804-956-2 uses beryllium-copper contacts with a gold-over-nickel finish. Gold provides low and stable contact resistance over many insertion cycles, while beryllium-copper delivers the spring force needed for reliable mating with QFP80 IC leads across thousands of test insertions.
What insulation and voltage ratings make this QFP80 socket suitable for high-reliability burn-in testing?
The socket provides 1,000,000,000 Ohm insulation resistance and a 700 VAC dielectric withstanding voltage, ensuring excellent electrical isolation between the 80 contacts during high-temperature burn-in tests where leakage currents and voltage stress must remain tightly controlled.
How does the IC51-0804-956-2 body size accommodate a QFP80 device in ATE fixtures?
The IC51-0804-956-2 body measures approximately 0.551 inch × 0.551 inch, sized to house an 80-pin QFP IC. Its polysulphone housing resists temperatures and chemicals encountered in burn-in ovens, and the bellowed contact style self-aligns leads during insertion into automated test equipment fixtures.
