Micropull IV Semiautomatic Wire Bond Pull Tester
The Unitek MICROPULL IV (MP4) is a semiautomatic machine designed to perform wire bond pull tests in the 0.5 to l000 gram-force range, using three interchangeable beams, at rates of up to one test per second.
According to industry statistics, insufficient bond strength is a major cause of device failure. Bond pull tests are routinely used to evaluate and/or control the mechanical strength of wire bonds in microcircuit devices. The Miyachi Unitek Micropull IV (MP4) is a semi-automatic machine designed to perform wire bond pull tests in the 0.5 to 1000 gram force range. It can automatically detect wire bond failures occurring during the test, as well as excessive wire bond loop height.
To perform a wire bond test, the operator need only position the hook directly under the midpoint of each wire bond. The hook is then raised until the bond is stressed to a predetermined value (non-destructive pull test-NDPT), or the wire breaks (destructive pull test-DPT). The MP4 displays the results and outputs them via an RS-232 type serial interface. Using three interchangeable beams, the MP4 may perform these tests at rates of up to one test per second.
The intent of the NDPT is to use a force great enough to cause weak bonds to fail, yet insufficient to damage good bonds. Recommended values for the maximum safe forces for NDPT may be found in MIL-STD-883, Method 2023. MIL-STD-883 Method 2001 covers DPT. The MP4 complies fully with and performs wire pull tests that meet the requirements of MIL-STD-883.
The accuracy of the MP4 system is 2% of reading or 2 gf, whichever is greater.
The MP4 software keeps track of the test number, device number and pull strength. At the conclusion of each test, the MP4 software displays and prints summary statistical data for the device and histogram information for the device or group of devices.
