Technical details and manufacturing context for Probe Card Interface
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Contact Resistance | ≤50 mΩ | Higher resistance causes signal attenuation and heating. |
| Current Rating | 1–5 A | Exceeding rating damages contacts. |
| Insulation Resistance | ≥1000 MΩ | Below this, leakage currents affect measurements. |
| Dielectric Withstanding Voltage | 500–1000 V DC | Ensures insulation integrity under high voltage. |
| Operating Temperature | -40–85 °C | Outside range, materials degrade. |
| Contact Force | 5–15 g | Too low causes poor contact; too high damages pads. |
| Probe Travel | 50–150 µm | Required for overdrive and planarization. |
| Planarity | ±10 µm | Ensures uniform contact across all probes. |
| Probe Pitch | 40–150 µm | Determines minimum pad size and density. |
| Number of Probes | 100–2000 pcs | Depends on device under test complexity. |
| Capacitance | ≤1 pF | Low capacitance for high-frequency signals. |
| Inductance | ≤1 nH | Low inductance for high-speed testing. |
| Weight | 0.5–2.0 kg | Affects handling and mechanical stability. |
| Connector Type | ZIF–LIF | ZIF for easy replacement, LIF for high density. |

Manufacturer profiles associated with Probe Card Interface.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
It provides the electrical and mechanical connection between the probe card and the test head/controller, ensuring precise alignment and reliable signal transmission during wafer testing.
The reference range is ≤50 mΩ. Higher resistance can cause signal attenuation and heating, so it should be verified for the specific model.
Materials include high-frequency PCB material, precision machined aluminum, gold-plated contact pins, and ceramic insulators, as listed in the directory.
Check the interface's parameters (e.g., number of probes, connector type, planarity) against your test requirements and confirm with the legal manufacturer or supplier.
