Vecoplus SMT:
the electroformed stencil
The electroforming process has several inherent advantages over other
techniques for producing stencils. The Nickel Vecoplus SMT
stencils are much harder than competitive products making it possible
to use them from 3 to 5 times longer. The increased hardness likewise
reduces the risk of damage during handling. Even the use of a metal
squeegee will not wear the stencil. The extended life cycle of the
stencil results in increased printing process yields and reduced costs
for the user.
Easy paste release
Another major advantage of electroforming is the ability to produce
smooth, tapered slot walls. By making the slot width on the printed
circuit board side of the stencil mask slightly larger than on the
squeegee side, the paste is not disturbed when the stencil is removed.
The much smoother side walls also allow for easy release of the solder
paste.
