Recommended Reflow ConditionsLead-free           Reflow Soldering Heat Endurance

/*回流焊条件(无铅)                              /回流焊耐热

                                                     

 

The reflow condition recommended above is according to the machine used by our company. Big differences will arise s a result of the type ofmachine, reflow conditions, method, etc used. Hence, before setting upyour reflow conditions, please confirm with the above./上面*的回流焊试验条件是根据本公司的回流焊设备测试结果得到.不同的试验设备﹑试验条件和试验方法及试验结果不同.因此回流焊试验条件的设定需要仔细地确认.

No mechanical and electrical defects are found after testing based on the

above profile and keeping under the conditions of room temperature and

humidity for 2 hours. /在该条件下进行回流焊,常温常湿条件下放置

2个小时后,无机械,电气特性缺陷发生。

Twice reflow test is acceptable with the test interval remaining 1 hour 

under the normal conditions.

/在常温常湿条件下,间隔1个小时可进行两次回流焊。

The reflow test profile may vary with the testing instruments.

/回流焊曲线图会因设备的不同有所差异
