The LPKF ProtoPrint S4 is a precision manual stencil printer. This tabletop model can be used for prototypes and for small batches of fine pitch SMT boards. Precise parallel separation between stencil and circuit board is guaranteed to meet the specifications of contact printing, as small as 0.4mm (16 mil) pitch (ultra-fine-pitch area).
Precise three-dimensional (X, Y, theta and clearance) adjustment of the stencil with three micrometer screws is vital for superior printing results. Excellent positioning accuracy and a specially designed lever for speed controlled parallel separation makes ultra-fine-pitch printing possible, as well as excellent screen printing. Micrometer screws easily and precisely adjust the PCB-screen gap.
The LPKF ProtoPrint S4 features freely adjustable, high clearance PCB nesting pins that allow boards populated on one side to be printed on the other. Frames, such as the LPKF ZelFlex, easily mount on adjustable clamps. The LPKF ProtoPrint S4 includes a test print screen for fast set up of new print jobs.
The ability to use milled polymer stencils (limited to 0.625 mm / 25 mil pitch) reduces costs and increases efficiency in the production of circuit board prototypes.
Insert plastic or metal stencils into double-sided LPKF ZelFlex ZR frames -- the fast exchange and patented stretching system of ZelFlex ZR frames ensures optimal tensioning and easy handling.
