PN436 No obvious clogging between QFP lead frame after 20 prints.

After 20 prints, the surface of QFP lead frame is observed to be uneven, causing noticeable clogging.

In the process of SMT printing, the stencil needs cleaning every 4 or 5 prints. With usage of  PN436  lead free solder paste, the cleaning frequency is substantially lowered, saving lots of time and costs of stencil cleaning, which in turn helps improve productivity.
 
PN436 lead free solder paste carries out perfect printing performance with excellent deposition, stable viscosity after continuous printing for 8 hours and full and complete printing shape without clogging.
