PCB stencil manufacturer important
PCB stencil manufacturer design is very important for solder paste transfer.
The sole purpose of an PCB stencil is to transfer solder paste to a bare circuit board.
Most line PCB stencil worker can easy transfer.
But why PCB stencil worker can do that?

PCB stencil manufacturer design
This must introduce PCB stencil manufacturer design.
A stainless steel foil is laser cut creating an opening for every surface mount device on the board.
Once the stencil is properly aligned on top of the board, solder paste is applied over the openings (making a single pass, using a metal squeegee blade).
When the stainless steel foil is separated from the board, solder paste will remain, ready for placement of the SMD.
This process, as opposed to hand soldering methods, ensures consistency and saves time.

PCB stencil manufuacturer suggestions
Stainless steel foil thickness and aperture opening size control the volume of paste deposited on the board.
Too much solder paste causes solder balling, bridging, and tomb-stoning.
A lack of solder paste creates insufficient solder joints. All of which compromise the electrical functionality of the board.
