Kako?
Spajkanje (spajanje) je spoj delov z dodajanjem materiala. Spajkanje delimo na mehko in trdo spajkanje. Za spajkanje potrebujemo orodje: spajkalnik, plinski gorilnik, naprava, ki se cin preliva…
Spajkalo:
-električna, plinska, spajkalo brez energije…
-nizko napetostna 40V…
-visoko napetostna 230V…
-z regulacijo temperature in z ne regulacijo
Moč spajkalnikov:
-spajkalniki z močjo 5W,
-25-40W, so za standardna vezja (elementi),
-50-100W, v energetiki (kabli),
-nad 100w, so pa za vodovode, kleparstvo,
Konice spajkalnika:
-bakrene (nizka cena, lahko jo oblikujemo, slabo zato ,ker baker oksidira),
-polkovinjene (bakrene, so ponikljene, železove; teh konic nesmmo obdelovat, samo čistit z gobico(mokro)),
-iz jekla (najdražje,specilizirana jekla, ne oksidira, dolga življenska doba, cca. 2,5mil. spojev),
-po obliki: ravne, sploščene, zavite,
Žica za spajkanje:
cin, lot, spajka.
Cin sestavljajo: kositer, baker, svinec, srebro.
Uporablja se cin brez svinca…(višje telišče 190°C), oblika žiče je okrogla.
Talila:
gašena solna kislina, pasta za spajkanje (cinol pasta), ne vsebuje kislin, kolifonija!, telila v spajki.
Pogoji za dobro spajkanje:
vstrezno orodje, dobro očiščen material, znanje spajkanja…
Potek spajkanja:
-krivimo z ustreznim orodjem,
-elemente ne spajkamo tik ob vezju,
-poskrbimo za dodaten odhod toplote,
Dodatne potrebe (pripomočki):
stojalo, stojalo za spajkalnik, gobica, pumpica, pletenica…
Kako?
 Pravilno spajkanje |
