5.1Porosity Test
5.1.1Porosity Test Method
Use EIA 364, Test Procedure 53A, Nitric acid test. Porosity test to be performed for 20 contacts, randomly selected per socket, five sockets.
5.1.2Porosity Test Criteria
Maximum of two pores per set of 20 contacts, as measured per EIA 364, Test Procedure 60.
5.2Plating Thickness
Measure various plating thickness on contact surface per EIA 364, Test Procedure 48, Method C or Method A. Test to be performed using 20 randomly selected contacts per socket, five sockets. No plating thickness measured shall be less than the minimum plating thickness specified in Section 3.9.3.
5.3Solvent Resistance
Requirement: No damage to ink markings if applicable. EIA
5.4Solderability
(Applicable for leaded sockets) Requirement: 95% coverage per ball/surface mount feature. EIA 364, Test Procedure 52, Class 2, Category 3. Test to be performed on 20 randomly selected contacts per socket, five sockets.
