+If you want to assemble 3 or more PCBs using surface mount parts, reflow soldering is safer and easier way instead of hand soldering. 
+However, reflow soldering requires solder stencils to print solder paste on the PCB pads.
+Generally, solder stencils are made of stainless steel foil and somewhat expensive.

+We introduce our method to prepare solder stencils in-house.
 This method is a low cost technique you can do yourself.
