This section applies to testing tinned copper surface by molten solder wetting characteristics, this characteristic expressed by a specific time. This part of the method is to use the sample of the molten solder ball split halves cut sample was measured into the sample stream into the solder balls around you to cover the time required for the sample. This time indication weldability of the sample. This part should GB/T 4909. 1-2009 together.

Test methods for bare wires Part 12. solderability test methods --- balls1 ScopeGB/T 4909 provisions of this part of the test equipment of bare wire ball method solderability test, sample preparation, measurement procedures, tests Evaluation results and the like. This section applies to testing tinned copper surface by molten solder wetting characteristics, this characteristic is represented by a specific time. This part of the method is to use a sample of molten solder ball split in half, cut the measurement sample flows into the solder balls to four weeks and the test sample Comp time live coverage required. This time indicates the solderability of the specimen. This section should be used in conjunction with the GB/T 4909.1-2009.2 Normative referencesThe following documents contain provisions which, through reference to GB/T 4909 to the present, constitute provisions of this section.
