The LPKF ProtoPrint S is a manual stencil printer from LPKF that prints solder paste on SMT prototypes and small batches. The ProtoPrint S prints down to 0.3 mm (12 mil) pitch using on-contact printing with parallel stencil separation. The ProtoPrint S is available in a standard version and a ProtoPrint S RP version that adds an integrated ZelFlex clamping frame for polyimide film stencils.[1][2][3]
What it is
The LPKF ProtoPrint S is a manual stencil printer for surface-mount technology (SMT) solder paste application. The machine is designed for prototyping and small-batch production of fine-pitch boards. Two configurations exist: the ProtoPrint S and the ProtoPrint S RP. The ProtoPrint S uses stainless steel stencils, while the ProtoPrint S RP includes a ZelFlex clamping frame for polyimide film stencils.[1][2]
How it works
The ProtoPrint S uses on-contact printing where the stencil contacts the PCB during the print stroke. Separation is achieved through a parallel vertical lift of the stencil from the board. The machine provides adjustment of the print table in X and Y (±10 mm) and rotation (±5°). A test print screen allows the user to print onto a film to verify setup before printing on a board.[2][1][3]
Where it fits in the process flow
The ProtoPrint S is used in the solder paste printing stage of SMT assembly, before component placement and reflow soldering. The machine can print on double-sided boards, allowing one side to be populated before printing the opposite side. A vacuum table option enables transfer of the board directly to the LPKF ProtoPlace S pick-and-place system without breaking vacuum.[2][3]
