What are Prototype SMT Stencils?

What you see here is the image of a prototype SMT Stencil.

Prior to manufacturing the PCBs in mass, a prototype of it is made. This is generally an expensive affair because it requires a lot of equipments. Manufactures of printed circuit boards usually outsource the advanced Prototype SMT Stencils.

I think you require a little bit of explanation about SMT stencils. While SMT implies Surface Mount Technology, the stencil means a thin sheet of metal where the various electronic components such as semi-conductors and chips are soldered.

Only after ordering a prototype PCB stencil and testing it to check whether it works alright, mass production of PCBs is undertaken.

Feeling elated with this newly gained knowledge?

There is some more to it. Producing the precision stencil is the most important aspect while developing a prototype. Laser cutting is employed to produce the basic stencil on which electronic components are soldered.

Fine Line Stencil manufactures laser cut prototype SMT Stencil that is consumed in thousands by various electronic printed circuit board assemblers.
