Compare with Metal parts, we must reserve space for ANT cover area to solve RF performance impaction issue.
First step is using CNC or stamping process to remove partial metal for reserving space, then using insert molding to fill
with plastic material in this space, adding putty to fill the gap, then using polish process to remove gap/step, finally we
will get final parts using painting for surface treatment, then we could get finished good parts.
Compare with Glass parts, some persons study using glass material for laptop housing, but most of glass material only
2D and bonding with plastic frame for core side feature. First trim glass plate, then using forming process to get the 2D
forming parts and using surface treatment to get the cosmetic surface side feature, then using molding to get the plastic
frame, finally we will get final parts using boding process.
