ASTM F1996-14

Отменен
Standard Test Method for Silver Migration for Membrane Switch Circuitry (Withdrawn 2023) — 3 стр.
Причина отмены This test method is used to determine the susceptibility of a membrane switch to the migration of the silver between circuit traces under dc voltage potential.

Formerly under the jurisdiction of Committee F01 on Electronics, this test method was withdrawn in January 2023 in accordance with section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.

Значение и использование

4.1 The effects of silver migration are short circuiting or reduction in insulation resistance. It is evidenced by staining or dicoloration between the cathode and anode conductive traces.

4.2 Accelerated testing may be accomplished by increasing the voltage over the specified voltages. (A typical starting point would be 5Vdc 50mA).

Область применения

1.1 This test method is used to determine the susceptibility of a membrane switch to the migration of the silver between circuit traces under dc voltage potential.

1.2 Silver migration will occur when special conditions of moisture and electrical energy are present.
