| Summary: | Soldering is used extensively in the electronic industry. It used to connect
printed circuit board to join the circuit between electronic parts. The quality and
reliability of electronic products strongly depend on those of solder joints. The
quality reliability of solder joint as the title of this project is to study about joint
solder of lead free solder (SnO.7Cu) and printed circuit board with various heat
treatments. The objectives of this project is to analyze the strength between solder
and printed circuit board by various heat treatment temperature besides investigate
whether the change of temperature treatment will affect the joint strength of solder
and printed circuit board. Tensile test is used in this project to analyze the reliability
of the solder joint. At the end of the project, the reliable and efficient temperature is
determined, 120°C at 1 hour heat treatment while unreliable temperature is 120°C at
2 hours of heat treatment. |
