Pájecí dráty

Pájecí dráty ALMIT

Dráty firmy ALMIT se všeobecně vyznačují následujícími vlastnostmi:

  • nulová prskavost a snížená kouřivost tavidla
  • možnost vyššího obsahu tavidla 3,5% – lepší pájitelnost
  • mnohem lépe a rychleji se taví a roztékají ( lepší prokovovací vlastnosti )
  • výrobce garantuje stejný obsah tavidla po celé délce drátu – pokud se při namotávání drát přetrhne je vyhozen a cívka se namotává znovu.
  • dráty šetří pájecí hroty – 6x delší životnost
  • dráty GUMMIX (stejné vlastnosti jako pasta s tímto názvem)
  • dráty pro nestandardní aplikace – pájení Al, Ni a nerezových vývodů
  • dráty se zvýšeným obsahem mědi (eliminace jevu „Cu leaching“ – rozpouštění měděných vývodů
    v pájce během pájení)
  • dráty pro pájení robotem
  • bezolovnatý drát (SW09 LFM48) s velmi aktivním (clean) tavidlem omyvatelným vodou..
