Foreword

GB/T 4909 "Test methods for bare wires" is divided into twelve parts. --- Part 1. General; --- Part 2. size measurement; --- Part 3. Tensile test; --- Part 4. torsion test; --- Part 5. --- bending test repeated bending; --- Part 6. bending test --- unidirectional bending; --- Part 7. winding test; --- Part 8. --- Brinell hardness test method; --- Part 9. continuity of coating --- more sodium sulfide; --- Part 10. Test for continuity of coating --- ammonium persulfate law; --- Part 11. Coating adhesion test; --- Part 12. solderability test methods --- balls. This section GB/T Part of 104,909, This Part replaces GB/T 4909.10-1985 "Test methods for bare wires - Test for continuity of coating ammonium persulfate law." Section compared with the GB/T 4909.10-1985 The main changes are as follows. --- According to GB/T 1.1-2000 requirements, and on the formatting has been modified, and the part of the text has been modified; --- Added "Normative References" chapter (1985 edition no; Chapter 2 of this edition); --- Modified with an organic solvent pretreatment regulations, and adds ammonia reagent provisions (1985 Version 2.2.3; Excerpts Chapter 3); --- Remove the test (1985 edition 3.1.2,5.3) for finished cable; --- Increased before testing the specimen surface cleaning requirements (edition 4.2).

1 Scope

GB/T 4909 provisions of this part of ammonium persulfate law continuity of coating test equipment, sample preparation, measurement procedures, test results Evaluation of fruit and the like. This section applies to test the copper conductor surface of the metal layer (such as tin, silver, nickel layer or the like) continuity. This test method GB/T 4909.9-2009 having equivalent effect, but no matter what method should meet product standards for gold Genus coating requirements shall prevail. This section should be used in conjunction with the GB/T 4909.1-2009.

3 Test Equipment

--- Glass cylinder 100mL; --- Chemically pure ammonium persulfate; --- CuSO4 chemically pure; --- Ammonia chemically pure; --- Ethanol or diethyl ether.

4 Sample Preparation

4.1 Sampling Sample delivery status by eight product packaging unit (circle or disc) components. Interception of a sample from each sample, each sample preparation When the depth of the solution is less than L, the specimen should be cut into several sections, the test process. 4.2 Pretreatment Cleaning coating specimens with ethanol or diethyl ether, and then with a clean, soft cloth and dried. Sealed with wax at both ends of the specimen head so that no copper exposed. Wax seal both ends should not be included in the determination of the length L within.

5 test procedure

5.1 The test solution had to produce ammonium 10g of ammonium persulfate dissolved in 500mL of distilled water, was added aqueous ammonia (specific gravity 0.90) 75mL, diluted with distilled water to 1000mL, prepared test solution temperature should be no higher than 35 ℃. ......
