Inspection Instruction of
PCB5-1-B-5V |
1.Check for scratches, marks, and appearance of tracks are
clean with a good finish. |
2.board should not be warped. |
3. Ensure all parts are exactly as per BOM (Bill of material) |
4. Ensure all components have been installed
to look good with a straight looking alignment |
5. Ensure the finish of soldering covers the
whole pad and has a shine. |
6. Check to ensure no excess solder is left,
as we don't want the possibility of creating shorts between pads |
7. Check insulation of wires is full
covering with no exposed wire. |

参考测试线路图
注意此PCB有两块相同分开的线路组成,PCB6-1-B-5V表示用底部的部分,PCB6-1-T-5V表示用顶部的部分,PCB6-1-2-5V表示用顶部和底部两部分都用
连接一个5VDC电源到J2,注意极性不能接反,J2的第一脚为正极
连接一个自复位开关到J3和J4
连接一个电压表到J1
接上电源到,未闭合连接到J3;J4开关时,连接到J1的电压表读数应是5VDC,相应的LED灯应不亮
闭合连接到J3;J4的任一开关时,连接到J1的电压表读数应是零,相应的LED灯应亮
如是PCB6-5-2-5V板,重复上述测试在另一部分
如上述测试合格,打上序列号码 |
