Pájecí pasty ALMIT - všeobcené vlastnosti
- velmi dobré vlastnosti při tisku (možné větší rychlosti stěrky a odtržení planžety), po tisku má velmi
ostré hrany a eliminuje zanášení šablony
- maximálně eliminuje tvorbu kuliček
- větší povrchovou přilnavostí čímž snižuje riziko ?Tomb-ston? efektu – velmi dobré vlastnosti při pájení v parách
- pasta se mnohem lépe a ryhleji roztéká
- eliminace jevu zvaný „chip floating“ (pasta nevytvoří meniskus, ale podteče pod součástku)
- eliminace zkratů u finepitch součástek po reflow procesu
ostré hrany a eliminuje zanášení šablony
Pasta ALMIT se také vyrábí ve specielních úpravách:
- tzv. Longlife provedení (L) - vydrží dvakrát déle bez ztráty vlastností.
- High speed (S) - pro tisk až 150mm/s.
- Pasta pro velmi těžce pájitelné a nestandardní povrchy (P) - tavidlo orientované na smáčivost
- GUMMIX - u této pasty po zapájení zůstává tavidlo plastické (neodloupne se, vhodné pro namáhané povrchy u nemytých produktů)
- slitiny jiné než klasické olovnaté/bezolovnaté - pájky s různými obsahy stříbra, stříbro nahrazeno bizmutem, indiem.., pasty pro bezolovnaté pájení profilem pro olovnaté pasty, pasta s velmi nízkým bodem přetavení (139 stupňů), např. pro pájení displejů a jiné..
