CCRETECH UF200R semiconductor prober station

The ACCRETECH UF200R is a fully automated, cost-effective semiconductor prober from ACCRETECH (Japan) for 120–200mm (5–8 inch) wafers. It's used for electrical testing (CP testing) of wafer-level chips before dicing.

What does it do?

Simply put: Before the wafer is diced into individual chips, probes contact the chip pads to perform electrical/functional testing, separating good and defective chips. Stage: Wafer Testing (CP)

Target: Primarily 200mm (8-inch), also suitable for 5/6-inch wafers

Typical Chips: Logic, Analog, Power Devices, Discrete Devices, MEMS

II. Core Specifications (At a Glance)

Wafer Size: 120/150/200mm (5–8-inch)

Positioning Accuracy: ±1.5μm (XY)

Moving Speed:

XY: Up to 300 mm/s

Z: Up to 30 mm/s

Temperature Range: -40℃ ～ +150℃ (Optional Temperature Control)

Stage: High-rigidity Z/θ platform, compatible with ultra-thin/warped wafers

Operation: Fully automated loading and unloading, automatic alignment, probe inspection

III. Main Functions

Fully Automated Testing Process

Automatic Wafer Loading → Image Alignment → Probe Contact → Electrical Testing → Segmentation and Recording → Automatic Unloading

Multi-Category Compatibility

Standard Logic, Analog, Power, MOSFET, Diode, Transistor, MEMS All can be measured. Wide temperature range and special tests. Complete options for low/high temperature, micro-current, high-voltage testing, etc. Ultra-thin/warped wafer processing. Backside adsorption + special handling mechanism, supporting ultra-thin (≤50μm) and high-warped wafers.

IV. Advantages (Compared to similar products)

High cost-performance ratio: Near the precision and platform of the high-end UF2000 (same as MMI), but at a more affordable price.

High throughput: XY high speed + quick pin change card, suitable for high-volume 8-inch production lines.

Stable and reliable: Mature ACCRETECH platform, low maintenance, long lifespan.

Flexible expansion: Modular design, can be added later with temperature control, high voltage, micro-current, dual-bin, etc.

V. Common comparisons (helping you quickly locate the right product)

UF200R: General 8-inch mass production, logic/power/discrete, cost-effectiveness priority.

UF190R: More compact, entry-level, biased towards discrete devices/small batches.

UF2000: High-end 8-inch, higher precision, wider temperature control, MEMS/ Advanced Technology

In short: The UF200R is the "mainstay cost-effective probe station" in the 8-inch mid-test market—it offers sufficient accuracy, high speed, stability, durability, and expandability, making it suitable for high-volume, multi-variety 8-inch production lines.
