You know the PCB assembly decision is very important PCB performance.
If you use low PCB stencil to assembly PCB components.
The PCB products performance were very bad.
Inexperienced PCB stencil design
An inexperienced CM may select a “middle ground” 5 or 6-mil thick stencil for a mixed-signal PCB design and thus eliminate the two different and critical cycles of paste deposition.
As a result, defects are created at assembly.
That also they use best material can’t produce best PCB stencils.
For example, if you have finer pitch devices such as QFNs or micro BGAs, there is the possibility of shorts between the balls.
