By such action, EIA does not assume any liability to any patent owner, nor does it assume any obligation whatever to

5、parties adopting the Standard or Publication. (From Project Number 3335, formulated under the cognizance of the EIA P-2.1 Ceramic and Mica Dielectric Subcommittee.) EIA INTERIM STANDARDS EIA Interim Standards contain information deemed to be of technical value to the industry, and are published at t

6、he request of the originating Committee without necessarily following the rigorous public review and resolution of comments which is a procedural part of the development of an EIA Standard. EIA Interim Standards should be reviewed on an annual basis by the formulating Committee and a decision made o

The qualification program is defined in table 1. Specification sheets can be added, as required, to define specific products or to cover unique/s

14、pecific requirements. 1.2 Preconditioning This process is intended to simulate exposure to the thermal and cleaning environments of the assembly process before qualification testing. The component assembly process simulation requirements for different types of processes are described in annex A 1.3

The encapsulating material, when applicable, shall be certified to meet the minimum flammabi

30、lity requirements of UL-94 V-O or V-1 and an oxygen index of 28% minimum as defined in ASTM-2863-91. The supplier must provide certificates of compliance to both tests upon request. When UL and oxygen-index testing are not feasible, the IEC “needle-flame“ test (EC 695-2-2), may be used. In all cases

31、, appropriate documentation must be maintained. 4.13 Solderability Capacitors shall be tested per EIA-198-D, Method 301, except: both terminals (terminations) shall be tested. 4.14 Surface mount thermal shock Capacitors shall be tested per EIA-198-D, Method 307.
