Specification

A. Test items for some features

1. Flux residue test after heating

  Test method

     Flux shall be put to ceramic pan and heat the pan. After heating, Flux residue shall be observed by using optical micro scope.

     (Conditions) Flux mass:40mg  Heating temp:360℃  Atmosphere:N2  Heating rate:1.3℃/s

                                     Holding time:None

Test result                          Table. Conditions of flux residue after heating

2. Comparison of flux residual rate after heating

  Test method

    Flux shall be weighed to ceramic pan and heat the pan. After heating, Flux residue shall be weighed and calculate Flux residue rate by the formula as below.

Flux residual rate  = Flux residue mass Flux mass × 100 (%)

 

               (Conditions) Flux mass:300mg  Heating temp:360℃  Atmosphere:N2  Heating rate:1.3℃/s  

                                         Holding time: None

B. Test result for basic characteristics

1. Halide activator content

    Test method

         After preparing the flux by 5.0±0.1g, it shall be put into 300ml beaker and then 2-propanol by 200ml shall be added to them.               They shall be dissolved as possible as we can by stirring at room temperature. Stirring them strongly by using the magnetic                stirrer, they shall be titrated by using the electric titration equipment with silver nitrate standard solution.

    Criteria

       Halide activator content shall be 0.08~0.14(%).

2. Flux solution resistivity test

     Test method

             0.100±0.005ml test flux solution (toluene solution including flux by 25%) and 50ml ion exchanged water shall be put into a           50ml beaker. They shall be boiled for 60s on a hot plate, cooled down by flowing water and put into the water bath adjusted                 20±2℃. After they shall be reach thermal equilibrium, they shall be measured in resistivity by conductivity meter.

      Criteria

              Resistivity shall be more than 1000Ωm.

3. Copper plate corrosion

     Test method

              3mm depth hole shall be made at the center of copper plate by using steel sphere of 20mm diameter. After pretreating                copper plate, the resin cored solder shall be provided to 3mm depth hole of it and melted. After that copper plate shall be put into        the chamber which is adjusted to 40±2℃,90~95% and kept in this condition for 96 hours. 96 hours later, copper plate shall be            removed from the chamber and checked about the corrosion condition. After flux residue on copper plate shall be cleaned off by        using suitable solvent, the corrosion condition under flux residue shall be checked too.

      Criteria

            Corrosion shall not be found.

4. Copper mirror corrosion

     Test method

    The test flux and standard rosin (2-propanol solution including flux by 25%) shall be made. 0.05ml of each test solution shall        be dropped on a copper mirror test plate. The test copper mirror plate shall be kept in a chamber adjusted 25±2℃, 50±5% for 24        hours. 24 hours later, each flux on the test plate shall be removed by 2-propanol. Corrosion shall be checked.

    Criteria

    Corrosion shall be not found, in comparison with standard rosin.

5. Surface insulation resistance

     Test method

             The test boards specified JIS shall be coated with toluene solution including flux by 25%. They shall be dried for 5 minutes in        a dryer adjusted to 100℃. After that they shall be soldered by floating for 3 seconds on solder bath adjusted to 270±3℃. Before          putting them into a chamber, the initial value of surface insulation resistance shall be measured. In this case, coaxial cable shall          be used for wiring between measurement pad on test board and insulation resistance meter. They shall be put into the chamber          adjusted to 85℃ 85% being careful for a waterdrop not to drop down on the test pattern and 24, 96, 168, 408, 648, 840 and 1008        hours later, surface insulation resistance shall be measured applying the bias voltage DC100V.

6. Electrochemical migration test

     Test method

             The test boards specified JIS shall be coated with toluene solution including flux by 25%. They shall be dried for 5 minutes in       a dryer adjusted to 100℃. After that they shall be soldered by floating for 3 seconds on solder bath adjusted to 270±3℃. Before         putting them into a chamber, the initial value of surface insulation resistance shall be measured. They shall be put into  the                   chamber adjusted to 85℃ 85% and applied DC45 to 50V being careful for a waterdrop not to drop down on the test pattern and         24, 96, 168, 408, 648, 840 and 1008 hours later, surface insulation resistance shall be measured applying the bias voltage                   DC100V. 1008hours later, the test boards shall be taken out from the chamber and confirmed whether there shall be any                     evidence of migration or not.
