Week 12

Tittle

• Construct the heart rate circuit on PCB board

Objective

• To draw PCB layout for the heart rate circuit
• To construct the circuit on the PCB board

Content/procedure

• At this stage,we need to draw the PCB layout of heart rate circuit using DipTrace.After that, we can do etching process and next put all the component on the PCB board before soldering process
• We put the heart rate circuit on the PCB board to reduce noise causes  by jumper

Result/Analysis

• We found that the result is same like on the breadboard.
• When circuit is put on the PCB board, its look neat and orderly

Conclusion

• We need to be careful when draw the circuit on the PCB layout because when mistakes occur on  the connected the component ,it will make all next process like etching disturbed.
