Where the Equipment Fits
From Wafer Probe to Final Test and Device Sorting.
Semiconductor testing depends on more than the tester alone. Device presentation, contact repeatability, temperature stability, test time and sorting logic must work together to maintain reliable results and production efficiency.
01
Wafer-Level Circuit Probing
Position the wafer accurately, align the probe interface and identify electrically acceptable dies before dicing.
02
Device Loading & Thermal Conditioning
Load packaged devices automatically and stabilize them at the required test temperature before contact.
03
Electrical Contact & ATE Execution
Present each device to the contact interface while the ATE system applies the selected test program and records results.
04
Result Sorting, Binning & Unloading
Direct tested devices into the correct output category according to pass, fail, grade or customer-defined binning rules.
Equipment Direction
Match the Test Stage with the Correct Equipment Route.
The equipment combination changes according to whether testing is performed on the wafer, after packaging, under controlled temperature or as part of high-speed production sorting.
| Test Requirement | Primary Equipment | Main Function | Key Selection Point |
|---|---|---|---|
| Wafer-Level CP Test | Wafer Prober + ATE | Probe individual dies before wafer dicing | Wafer size, probe interface, alignment and test program |
| Packaged IC Final Test | Test Handler + ATE | Automated electrical test and result sorting after packaging | Package type, contactor, tester interface and throughput |
| Hot or Cold Testing | Temperature-Controlled Test Handler | Condition and test devices at the required temperature | Temperature range, soak time and thermal stability |
| High-Speed Device Sorting | Turret, Gravity or Pick-and-Place Handler | Rapid device presentation, testing and multi-bin sorting | Index time, package protection and output configuration |
| Engineering & Device Evaluation | Probe Station or Flexible Test Platform | Device characterization, failure analysis and development testing | Measurement access, flexibility and changeover requirements |
Selection Priorities
How to Select Semiconductor Test & Handling Equipment.
Before comparing models, define the test stage and the conditions that affect device compatibility, contact reliability, output and long-term equipment support.
Test Stage & Device Form
Confirm whether the project involves wafer-level CP, packaged-device final test, engineering evaluation or production sorting.
Package, Tooling & Contact Interface
Review package dimensions, lead or ball layout, socket, contactor, change kit and device-orientation requirements.
Temperature Test Requirements
Define the required test temperature, conditioning method, soak time and stability expectations for the actual device.
Throughput & Index Time
Compare handler movement time, tester test time, parallel-site capability and the required production output.
Tester Integration & Communication
Verify mechanical docking, electrical interface, communication protocol, test-head arrangement and software compatibility.
Maintenance & Installed-Base Support
Consider spare-parts availability, change-kit continuity, repair capability, operator knowledge and future replacement planning.
Device and Package Applications
Equipment configuration must be verified for the actual package format, electrical test requirement and production environment.
Flexible Project Support
Support Beyond a Standard New-Equipment Purchase.
Test operations may require available legacy platforms, replacement handlers, tester-compatible configurations, spare parts, contact hardware or repair support to maintain installed production.
Available Inventory & Legacy Platforms

Semiconductor Test & Handling Equipment FAQ.
What does a semiconductor test handler do?
A semiconductor test handler automatically loads packaged ICs,
conditions them at the required temperature, presents each device
to the contact interface and sorts the tested devices according
to results received from the ATE system.
What is the difference between a test handler and an ATE system?
The test handler manages the physical device movement, temperature,
positioning, contact and sorting process. The ATE system applies
electrical test signals, measures device responses and determines
the test result. The two systems normally operate together.
What is the difference between CP and final test?
CP, or circuit probing, tests individual dies while they are still
on the wafer using a wafer prober and probe interface. Final test
is performed after packaging and normally uses a test handler,
contactor and ATE system to test and sort completed devices.
Which test handler type is suitable for my device?
The correct handler type depends on the package format, device fragility,
orientation, test temperature, throughput requirement, contact method,
output format and tester interface. Gravity, turret and pick-and-place
handlers are suitable for different production conditions.
Can a test handler perform hot and cold testing?
A temperature-capable test handler can condition devices before
electrical testing, but the supported range and stabilization method
depend on the machine configuration. The required temperature,
soak time and production output should be confirmed before selection.
Can a used or refurbished test handler be suitable for production?
Yes. Suitability depends on machine condition, package tooling,
tester compatibility, temperature configuration, control-system status,
spare-parts availability and the required production output.
The exact configuration should be inspected before purchase.
What parts are commonly required for test handler support?
Common requirements include package change kits, sockets, contactors,
nests, tracks, belts, sensors, motors, pneumatic components,
temperature-control parts, interface hardware and control modules.
Compatibility should be verified using the machine model and part number.
What information should be provided for a test-equipment inquiry?
Provide the device package, dimensions, test stage, required temperature,
tester model, handler model if known, contact interface, expected UPH,
input and output format, preferred equipment condition and destination country.
