Tailoring is accomplished by evaluating
35、the applicability of each requirement for the specific application. Upon completion of the evaluation, requirements may be added, modified or deleted. Tailoring decisions, including rationale, shall be documented. 5 Packaging application requirement 5.1 General Transportation of ESDS requires packag
36、ing that provides protection from electrostatic hazards. Within an EPA in which all ESD risks are well controlled, ESD protective packaging may not be necessary. 5.2 Inside an EPA Packaging used within an EPA shall consist of dissipative or conductive materials for intimate contact. Items sensitive
37、to 100 V human body model (HBM) may need additional protection depending on application and program plan requirements. NOTE Dissipative materials are preferred for intimate packaging in situations where charged device model (CDM) damage is a concern. BS EN 61340-5-3:2010 8 61340-5-3 IEC:2010 5.3 Out
38、side an EPA Transportation of sensitive products outside of an EPA shall require packaging that provides both: a) dissipative or conductive materials for intimate contact; b) a structure that provides electrostatic discharge shielding. NOTE 1 If electrostatic field shielding materials are used to pr
39、ovide discharge shielding, a material that provides a barrier to current flow should be used in combination with the electrostatic field shielding material. NOTE 2 Dissipative materials are preferred for intimate packaging in situations where charged device model (CDM) damage is a concern. 6 Classif
40、ication of ESD packaging material properties 6.1 General Materials and packages that are useful in preventing damage to sensitive electronic devices exhibit certain properties. These properties include: a) resistance properties: conductive; dissipative; b) Shielding properties: electrostatic dischar
41、ge; electrostatic field. 6.2 Material resistance properties Most standard packaging materials are electrically insulative and insulative materials retain charge. Making the package less insulative provides a path for the charge to dissipate from the package to a material at a lower potential. Specif
42、ic ranges of resistance are useful for different purposes. Packaging can be classified by these resistance ranges of its construction. 6.2.1 Resistance of conductive materials Conductive materials may be surface conductive, volume conductive or both. A surface conductive material shall have a surfac
43、e resistance of 1 104 . Volume conductive materials shall have a volume resistance 1 104. 6.2.2 Resistance of electrostatic field shielding materials Within the conductive materials classification, electrostatic field shielding materials shall have a homogeneous layer with a surface resistance of 1
44、103 or a volume resistance of 1 103. Other methods may also define the electrostatic field shielding classification. NOTE These resistance values do not necessarily imply RFI/EMI/EMP shielding. BS EN 61340-5-3:201061340-5-3 IEC:2010 9 6.2.3 Resistance of dissipative materials A static dissipative ma
45、terial shall have a surface resistance 1 104 and 1 1011, or a volume resistance 1 104 and 1 1011. 6.2.4 Resistance of insulative materials Electrostatic insulative materials have a surface resistance 1 1011, or a volume resistance 1 1011. 6.3 Material electrostatic shielding properties NOTE Electros
46、tatic shielding materials protect packaged sensitive electronic items from the effects of electrostatic discharges and fields that are external to the package. 6.3.1 Electrostatic discharge shielding Electrostatic discharge shielding packaging is capable of attenuating an electrostatic discharge. Th
47、e calculated energy allowed inside a static discharge shielding bag shall be less than 50 nJ when tested according to IEC 61340-4-8 or equivalent test method modified to accommodate the product. 6.3.2 Electrostatic field shielding Electrostatic field shielding packaging is capable of attenuating an
48、electrostatic field. NOTE Classified field-shielding materials may allow current flow through their volume. 7 Technical requirements for ESD protective packaging 7.1 Packaging and material properties Table 1 and 2 provide test methods for determining material classifications for finished packages an

When possible, testing should be performed on the finished package. 7.2 Packaging marking 7.2.1 Classification symbol ESD protective packaging shall be marked with the ESD classification symbol as shown in Figure 1 or in accordance with customer contracts, purchase orders, drawings or other documentation. 7.2.2 Packaging classification The primary function code shall be marked below the ESD classific
