Web1 apr. 2024 · This measure of bond strength is extremely important in determining two features: 1) the integrity of the metallurgical bond which has been formed, and. 2) the quality of ball bonds to die or package bonding surfaces. This test method covers thermosonic (ball) bonds made with small diameter wire from 15 μm to 76 μm (0.6 mil to 3.0 mil). … WebWire pull testing is the most basic type of wire bond test, but testing procedures can vary based on thickness. Typically, wires up to 3 mil in diameter are classified as thin. Wires with larger diameters are …

WebWire bond strength and acceptability of wire-bonded parts can be evaluated using either a destructive pull test (DPT) or a non-destructive pull test (NDPT). The most commonly accepted standards for these tests are MIL-STD-883, Method 2011.7 Bond Strength and MIL-STD-883, Method 2024.5, respectively.

MIL-STD-883E BOND STRENGTH (DESTRUCTIVE BOND PULL TEST)
WebThe principle behind basic wire bond testing is positioning of a hook underneath the wire and pulling in the Z axis either until the bond breaks (destructive testing) or a pre-defined force is reached (non-destructive testing). Wire bond testing is covered by the external standard MIL-STD-883 (Methods 2011.7 for destructive testing and 2024.5 ... WebThe FMT-W40 is a motorised wire-terminal pull tester. It is available in 2 models with a tensile strength capacity up to either 500N (110 lbf) or 1000N (220 lbf). It is rugged, … WebNondestructive Pull Test Standards Failure Criteria: According to Mil-STD-883, any wire bond pull which causes a separation at an applied pull force value less than the value assigned to the wire composition in the table is considered a failure.
