SMT Foil Stencils are laser cut solder paste stencils designed to work on their own for hand printing or with stencil tensioning systems. These laser cut stencils do not need to be permanently glued in a frame. These so-called frameless stencils are

For the DIYer, hobbyist or technical researcher there are times where all you need is a simple means to apply solder paste for SMT devices for a few simple boards. In those cases a plastic SMT stencil may be the right solution. Eliminate the tedious

BEST Inc., has developed a line of Kapton™ SMT stencils for the prototype assembly market. These stencils, available in 4,5 and 6 thicknesses, present very flat coplanar printing surfaces for solder paste printing. . They are designed to be used when the there are very few boards to be made at one time and the pitch of the components is 1.00 and above.

Some of the new handheld communication devices offer real challenges to the paste printing process. Normally, there are very small devices like 01005 chip components as well as 0.3 mm pitch uBGA along with other devices that require higher deposits of solder paste. Surface mount connectors or RF shields with coplanarity issues fall into this category. Aperture sizes for the small devices require a stencil thickness in the 50 to 75 um (2-3 mils) range for effective paste transfer whereas the RF shield and SMT connector would like at least 150 um (6 mils) paste height. Spacing is too small to use normal step stencils. This paper will explore a different type of step stencil for this application; a "Two-Print Stencil Process" step stencil. Here is a brief description of a "Two-Print Stencil Process". A 50 to 75 um (2-3 mils) stencil is used to print solder paste for the 01005, 0.3 mm pitch uBGA and other fine pitch components. While this paste is still wet a second in-line stencil printer is used to print all other components using a second thicker stencil. This second stencil has relief pockets on the contact side of the stencil any paste was printed with the first stencil. Design guidelines for minimum keep-out distances between the relief step, the fine pitch apertures, and the RF Shields apertures as well relief pocket height clearance of the paste printed by the first print stencil will be provided.
