1 Folasaga

O le fa'amae'aina o luga e taua tele mo le fa'atuatuaina ma le fa'atinoga o le PCB laupapa fa'asalalau lolomi. Electroplated auro malo malosi ma faatofu auro ENIG Electroless Nickel Immersion Auro o ni auala e lua e masani ona faʻaaogaina auro. O lenei lipoti e iloilo ai o latou uiga faʻapitoa, tulaga lelei, tapulaʻa, ma le faʻaogaina talafeagai.

Maualuluga maualuga ona o le mafiafia o le auro.
Lelei mo la'ei maualuluga fa'ata'ita'iga so'oga pito.
E mana'omia le ufiufi lavelave mo le fa'ailoga filifilia.

B Faatofu Auro ENIG

Metotia. Autocatalytic chemical displacement tali e aunoa ma le taimi i fafo.
Laupapa. Nickelphosphorus layer 36 μm lanu auro manifinifi 00301 μm.
Vaega Autu.
Fa'ato'a fa'apipi'i i luga o mea uma 'apamemea fa'aalia.
Laupapa mafolafola lelei mo vaega finepitch.
E a'afia ile fa'aletonu o le papa uliuli pe a le manuia le fa'atonuga.

6 Faaiuga

O auro fa'apipi'i fa'aeletise e sili atu i le fa'aogaina o masini ma fa'aoga fa'apitoa ae fa'atupuina tau maualuga. Faatofu auro e ofoina atu se tali paleni mo le tele o mamanu PCB faapisinisi ae faaitiitia lavelave faagasologa. Filifiliga e fa'alagolago i mana'oga fa'atinoga, tala fa'atatau o tupe, ma le fa'aogaina o le si'osi'omaga. Fa'ata'ita'iga fa'atosina fa'ata'ita'iga fa'aeletise fa'aeletise ENIG ua fa'atuputeleina le fa'aogaina e fa'asilisili ai fua fa'atatau o tau.
