Tempotac 385

Tempotac (385-TEM) is a well-established tacky flux. The flux has the basic ingredients of a solder paste flux including some activators.

 With the introduction of lead-free solders which, include higher process temperatures, a new product has been introduced;  This is the 120-TEM. This product  can withstand higher temperatures and can be supplied in a blue color version for inspection purposes when required.


Tempotac is used in all kinds of rework applications:

  • Reballing: where availability of BGA's with lead free spheres is limited, replace lead free spheres by SnPb spheres before mounting (e.g. military, aerospace, medical etc.)
  • Repair applications: remove and replace BGA's
  • Placement of BGA's - insted of using solder paste, Tempotac can be used
  • Remove bridges in rework of QFP's
Tempotac is safe, it passes all SIR tests. However if customers don’t like the minimal residues, these can be removed using a typical flux-remover.
