19、uctor die to package headers or other substrates (for the purpose of this test method, the term “semiconductor die” should be taken to include passive elements). This test method is generally only applicable to cavity packages or as a process monitor. It is not applicable for die areas greater than

20、10 mm2. It is also not applicable to flip chip technology or to flexible substrates. NOTE 1occurs, the type of failure resulting from the application of force and the visual appearance of the residual die attach medium and the header/substrate metallization. 2 Description of the test apparatus The a

21、pparatus for this test shall consist of a load applying instrument in the form of a linear motion force-applying instrument or a circular dynamometer with a lever arm. In addition it shall have the following: a) a contact tool which applies a uniform load to the edge of the die, perpendicular to the

22、 die mounting plane of the package or substrate (see Figure 3). A compliant material on the contact tool may be used to ensure that the load is applied uniformly (see Figure 1); b) an accuracy of 5 % of full scale or 0,5 N, whichever is the greater tolerance; c) a means of indicating the load applie

23、d; d) a facility, fitted with suitable light source, to allow visual observation (e.g. at 10 magnification) of the die and contact tool during testing; e) a fixture with rotational capability relative to the die contact tool and package/substrate holding fixture to allow line contact of the tool alo

24、ng the whole edge of the die from end to end (see Figure 2). NOTE Many measuring equipments are graduated in kilogram-force (kgf) (1 kgf = 9,8 N). Page 3NOTE 2 In cavity packages, die shear strength is measured in order to assure the strength of the die attachment within the cavity. In non-cavity pa

25、ckages, such as plastic encapsulated packages, die bonding is used to prevent die movement until the resin mould is completely cured. Normally, specification of the die shear strength and the minimum adhesion area of die bond after moulding are unnecessary, except in the following circumstances: whe

26、n the die needs to be electrically connected to die pad; when heat from the die needs to be diffused through the die bond.This determination is based on a measure of the force applied to the die or to the element, and, if a failure BS EN 60749-19:2003+A1:2010EN 60749-19:2003+A1:2010 (E)3 Test method

27、 A force sufficient to shear the die from its mounting, or equal to twice the minimum specified shear strength (see Clause 4), whichever is the smaller, shall be applied to the die using the apparatus of Clause 2, with the following provisions. a) When a linear motion force-applying instrument is us

28、ed, the direction of the applied force shall be parallel with the plane of the header or substrate and perpendicular to the die being tested. b) When a circular dynamometer with a lever arm is employed to apply the force required for testing, it shall be pivoted about the lever arm axis and the moti

29、on shall be parallel with the plane of the header or substrate and perpendicular to the edge of the die being tested. The contact tooling attached to the lever arm shall be at a proper distance to ensure an accurate value of applied force. c) The die contact tool shall load against an edge of the di

30、e which most closely approximates a 90 angle with the base of the header or substrate to which it is bonded (see Figure 3). d) After initial contact with the die edge and during the application of force, the contact tool shall not move vertically with respect to the die such that contact is made wit

31、h the header/substrate or die attach medium. If the tool rides over the die, a new die may be substituted or the die may be repositioned, provided that the requirements of item c) of Clause 3 are met. 4 Failure criteria The strength of attachment of a die shall be considered to have failed the test

32、if any of the following criteria exists: a) Unless otherwise specified in the relevant specification, die separation at a force not greater than the following: 1) 4,1 mm2 die area 10 mm2: 25 N, 2) die area 10 mm2: not applicable (see clause 1); b) die separation at a force less than 1,25 times that

33、in item a) above and evidence of less than 50 % adhesion of the die attach medium to the die (as determined by visual inspection); c) die separation at a force less than 2 times that in item a) above and evidence of less than 10 % adhesion of the die attach medium to the die (as determined by visual

34、 inspection). NOTE Residual die material attached in discrete areas of the die attach medium should be considered as evidence of such adhesion. 5 Requirements When specified, the force required to achieve separation and the category of the separation shall be recorded.

36、etails shall be given: a) Minimum die attach strength if other than that given by the expressions in item a) of Clause 4. b) The number of devices to be tested and acceptance criteria. c) Requirements for data recording, when applicable (see Clauses 5 and 6).
