Manual SMT Stencil Cleaning

Apart from an automated cleaning process for stencils, SMT adhesive and solder paste residues can also be removed manually. A manual stencil wash process is oftentimes a popular alternative if the throughput of the stencils that need to be cleaned is low as, for example, it is when building prototypes.
