Key Features

  • Designed for QFP80 IC packages with precise bellowed-type contact alignment
  • Beryllium-copper contacts with gold-over-nickel finish for reliable low-resistance mating
  • 700 VAC dielectric withstanding voltage for robust electrical isolation
  • 1,000,000,000 Ohm insulation resistance ensuring high signal integrity
  • Polysulphone housing for thermal and chemical resistance in demanding environments

Applications

The IC51-0804-956-2 is used in test and burn-in sockets for QFP80 ICs, enabling repeated insertion and removal without soldering during development and production testing. Its bellowed Be-Cu contacts provide consistent low contact resistance across thousands of cycles, making it ideal for engineering evaluation boards and incoming inspection fixtures. This socket also fits automated test equipment (ATE) setups where reliable 80-pin QFP device handling is required.

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.
