The material properties of the eutectic 63Sn/37Pb solder, the hypoeutectic 96.5Sn/3.0Ag/0.5Cu and the PCB were all dependent with temperature.
Except the solder alloys, all the other materials are modeled as linear elastic material, but PCB is treated as linear orthotropic material, as shown in Table 2.The left side of the model is the symmetry axis and the bottom right node is fully constrained from axial displacement (UX=UY=0) to prevent rigid body motion.

Design and Fabrication of RC Quad-Copter for Video Surveillance Chiranjeet Paul1, a*, Nadimpalli Raghukiran2, b 1,2School of Mechanical and Building Sciences, VIT University, Chennai, India.
The tensile strength of the material is 3445MPa and the compressive strength is 1080MPa.
In general aluminum is also used as frame material, but this material gives us strength and resistance nature since we are dealing with surveillance operation.
Other prescribed material for frame is carbon fiber, plastic and also balsa wood.
