16、 human body model (HBM) electrostatic discharges (ESD) and the basic requirements for equipment used to develop and verify these waveforms. This standard covers HBM ESD waveforms for use in general test methods and for application to materials or objects, electronic components and other items for ES

17、D withstand-test or performance-evaluation purposes. The specific application of these HBM ESD waveforms to non-powered semiconductor devices is covered in IEC 60749-26. The waveforms defined in this standard are not intended for use in the testing of powered electronic systems for electromagnetic c

18、ompatibility (EMC), which is covered in IEC 61000-4-2. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 unit under test UUT material, object, item or product to be subjected to the HBM ESD test 2.2 UUT failure condition in which a UUT does not

19、 meet one or more specified parameters as a result of the ESD test 2.3 ESD withstand voltage maximum applied ESD voltage level that does not cause failure parameter limits to be exceeded, provided that all UUTs stressed at lower levels have also passed EN 61340-3-1:2007 4 3 Equipment 3.1 HBM ESD wav

20、eform generator This equipment produces an electrostatic discharge current pulse simulating an HBM ESD event for application to the UUT. The equivalent waveform generator circuit and tester evaluation loads are illustrated in Figure 1. 3.2 Waveform verification equipment 3.2.1 General Equipment capa

21、ble of verifying the HBM current waveform is defined in this standard. This equipment includes but is not limited to a waveform recording system, a high-voltage resistor and a current transducer. 3.2.2 Waveform recording system The waveform recording system shall have a minimum single shot bandwidth

22、 of 350 MHz. 3.2.3 Evaluation loads Two evaluation loads are necessary to verify the functionality of the waveform generator: a) load 1: a shorting wire; b) load 2: a 500 low-inductance resistor, with a tolerance of 1 % appropriately rated for the voltages that will be used for waveform qualificatio

23、n. The lead length of the evaluation loads (shorting wire or resistor) shall be as short as possible and consistent with connecting the evaluation load to the appropriate reference terminals (A and B in Figure 1) while passing through the current transducer. 3.2.4 Current transducer The current tran

24、sducer shall have a minimum bandwidth of 350 MHz. 4 HBM current waveform requirements 4.1 General Prior to UUT testing, HBM ESD waveform generator qualification shall ensure waveform integrity of the discharge current through both a shorting wire and a resistive load. The shorting wire waveform requ

25、irements are specified in Figures 2a and 2b for all positive and negative voltages defined in Table 1, while the resistive load waveform requirements for 1 000 V are shown in Figure 3 and Table 1. 4.2 Waveform qualification and verification Equipment qualification shall be performed during initial a

26、cceptance testing. Re-qualification is required whenever equipment repairs are made that may affect the waveform. Additionally, the waveforms shall be verified periodically. 5 EN 61340-3-1:2007 If a test fixture or circuit board is used to perform UUT testing, the test fixture board shall also be us

27、ed during equipment qualification tests. If the waveform no longer meets the waveform parameters described in Table 1 and Figures 2a, 2b and 3, all ESD testing performed after the previous satisfactory waveform check shall be considered invalid.

NOTE 1 The performance of th

NOTE 2 Precautions should be taken in the design of the waveform generator to avoid recharge transients and double pulses.

35、s appropriate to the UUT shall be established for the following parameters: sample size; pulse count; pulse interval; stress voltage levels; test temperature and humidity; relevant parameter specification limits indicating ESD test failure. 5.2 Evaluation of UUTs that have electrical terminals Evalu

36、ation of the ESD robustness of a UUT that has electrical terminals will often require that the terminals are classified into different types, for example, input, output, power supply or ground. Each non-power supply terminal shall then be tested (one at a time) with respect to power supply or ground

37、 terminals. 9 EN 61340-3-1:2007 In the case of the evaluation of UUTs that have electrical terminals, its purpose should be ti find the weakest pin combination and failure threshold for HBM. Thus, UUTs that do not have many electrical terminals are generally tested for HBM on all pin combination; bu

38、t, in the case of UUTs having many electrical terminals, it is possible to select the test pin combination as a pin grouping. The specific application of the HBM waveform to determine the ESD robustness of semiconductor devices is given in IEC 60749-26. 5.3 Evaluation of UUTs that do not have electr

39、ical terminals In the case where the UUT is a material or an object that does not have electrical terminals (for example, packaging materials), it may be necessary to apply the waveform to the UUT via applied electrodes or other appropriate means. 6 Test procedure An appropriate test procedure shall

40、 be defined according to the specific application. NOTE 1 The specific application of the HBM waveform to determine the ESD robustness of semiconductor devices is given in IEC 60749-26. It is permitted to use any voltage level as the starting stress level. One pulse of both polarities shall be appli

41、ed for all UUT terminal or electrode combinations and stress levels. NOTE 2 Some types of UUT may have “fail windows” in which no failures are sustained over a range of applied ESD stress levels (for example, no fail at 500 V, fail at 1 000 V, no fail at 1 500 V and fail again from 2 000 V upwards).

42、 It is recommended that no stress level should be missed in order to detect such fail windows. It is permitted to use separate samples for each UUT stress combination and/or polarity. It is permitted to use the same samples at the next higher voltage level if all UUT samples pass the failure criteri

43、a at testing after stressing at the lower level. If a different UUT sample is stressed at each level and/or combination and/or polarity, it is permitted to perform UUT testing after all samples have been stressed. 7 Failure criteria A UUT is considered to have experienced an ESD failure if it does n

44、ot meet all relevant parameter specifications following ESD test. 8 HBM ESD withstand classification An appropriate classification system for the application shall be established if required. NOTE The ESD withstand voltage will normally be an appropriate basis for classification but in some cases ot

45、her bases may be used. In many cases it will be sufficient to refer to the UUT ESD withstand voltage without the need for an additional classification system. The basic HBM ESD withstand classification applicable to semiconductor devices is given in IEC 60749-26. EN 61340-3-1:2007 10 Bibliography IE
