The Royce Instruments System 610 is a wire pull-test bond tester designed for precision testing of wire bonds. It is a robust instrument capable of 100 gram testing force with a 0.1 gram resolution, making it suitable for a wide range of applications requiring accurate and repeatable bond strength measurements.
Function Description:
The System 610 is primarily used for wire pull testing, a method to determine the mechanical strength of wire bonds in microelectronic devices. It operates in both manual and semi-automatic test modes, offering flexibility for different testing needs. The system measures the force required to pull a wire until it breaks or detaches, providing critical data for quality control and process optimization in semiconductor manufacturing and related industries.
Key functional components include:
- Mainframe: The core unit houses the illumination system, LCD display, and ports for peripherals like a mouse, parallel printer, and RS232 serial communication. It incorporates standard features such as pull hook rotation and collision sensing, enhancing operational safety and efficiency.
- Optics: The system is equipped with a Leica S6 zoom microscope, featuring 20X eyepieces, a focusing arm, and a magnification range of 6.3x to 40x. This allows for precise visual alignment and inspection of the wire bonds before and during testing.
- Wire Pull Hooks: Standard wire pull hooks are available in diameters from 0.002" to 0.010". The hook diameter should generally be at least twice the diameter of the bonding wire to ensure proper engagement and accurate testing. Custom hooks can also be manufactured to user-specified dimensions.
- Sample Holders (SH) and Manipulators (MPS): The System 610 supports various sample holders and manipulators to accommodate diverse sample types and sizes.
- MPS-12 Manipulator: Connects to any Royce Instruments' test piece holder (TPS) to secure samples on the System 610.
- MPS-14 Manipulator: Utilizes a 4:1 pantograph linkage, which aids the operator in positioning parts with high precision.
- TPS-55 Sample Holder: A universal test piece holder suitable for many sample types. Its stepped jawset's clamping force is adjustable via a precision leadscrew.
- Control Interface: The system is controlled via front panel buttons, a three-button mouse, and an optional keypad. The LCD display provides real-time information on test status, pull force, and fail codes.
- Test Modes:
- Manual Testing: The operator manually positions the test hook and initiates each test.
- Semi-Automatic Testing: This mode automates certain steps, allowing the user to set a test hook position (Z-axis and rotation) that the system remembers and repeats. After initial setup, the operator only needs to position the sample and start the test.
- Failure Codes: The System 610 can assign failure codes to each test. Codes 1-9 are operator-assignable after inspecting the failure, while codes 10-13 are automatically assigned by the system. The optional keypad or mouse can be used for entry.
- Data Output: Test results and statistical reports can be printed via an optional thermal printer or sent to an external system via the RS232 serial port. The RS232 output format includes accumulative test number, test force, failure mode description, and failure mode code.

Usage Features:
- Test Setup Menu: This comprehensive menu allows operators to configure various high-level options, including test parameters (NDT limit, speed, NDT hold time, test stops at, hook Z speed, hook θ speed), printer output settings, time and date, operator identification, and sample identification. Fail code descriptions (CODE 1-9) can also be edited here.
- Statistics Menu: Provides statistical data and options for analyzing valid destruct test results. Operators can view minimum, maximum, mean, range, standard deviation (σ, STD DEV), Cpk, Cpl, and Cpu values. Upper and lower specification limits can be entered for statistical analysis. Reports can be printed or sent via RS232.
- Service Menu: Contains calibration and lighting control options.
- Mouse Control: The three-button mouse is used for test functions, pull hook placement (vertical movement and rotation), and menu navigation. Movement speed and rotation sensitivity are adjustable.
- Keypad (Optional): Facilitates alphanumeric data entry for items like group numbers, operator names, part numbers, and editing fail code descriptions.
- Display: The LCD shows the test number, pull force, fail code, test mode (Destruct/NDT, Auto/Manual), and test status (Ready/Pulling).
- Collision Sensing: A standard feature that stops the test head movement if the hook makes contact with the sample, preventing damage.
- Park Time: Configurable setting for the system to return to the reset position after a period of idle time.
Maintenance Features:
- Calibration: Test result accuracy is maintained through system calibration. Calibration procedures should be performed on a monthly basis.
- CALIBRATE: Guides the operator through the calibration process.
- CHECK CALIBRATION: Allows verification of the calibration status by hanging a known weight on the test hook and comparing the displayed value.
