ENIG PCB inomisa ngura uye inochengeta zvemagetsi zvichishanda munzvimbo dzakaoma.
Nzvimbo yaro yakatsetseka inobatsira nekutengesa zviri nyore, kunyanya kune zvidimbu zvidiki.
ENIG inogona kugara yakanaka kwemakore makumi maviri, yakanakira kushandiswa kwenguva refu.
Miedzo inoitwa kuti ive nechokwadi chekuti ENIG inoshanda nemazvo uye yakavimbika.
ENIG inodhura kupfuura mamwe mapeji asi inogara kwenguva refu uye inoshanda zviri nani.
Iyo ENIG PCB Maitiro
The ENIG maitiro chinhu chakakosha pakugadzira maPCB akasimba. Iine matanho makuru maviri: kuwedzera nickel uyezve goridhe. Matanho ese ari maviri anobatsira PCB kugara kwenguva refu uye kushanda zvirinani.
Electroless Nickel Plating
Nhanho yekutanga kuwedzera nickel kumhangura. Izvi zvinoitwa pasina kushandisa magetsi. Nei izvi zvichikosha? Nickel inodzivirira mhangura kubva ku ngura uye inoita hwaro hwegoridhe.
Nickel inovhara nzvimbo dzisina kuenzana nemakomba madiki zvakaenzana.
Hapana magetsi zvinoreva kuti hapana kusaenzana coating matambudziko.
Nickel ine 10-12% phosphorus inodzivisa ngura, zvichiita kuti isimba.
Iyo nickel layer inochengeta PCB yakachengeteka mumamiriro ezvinhu akaoma. Iyi nhanho inobatsira magetsi ako kugara akavimbika kwenguva yakareba.
Kunyudza Goridhe Coating
Tevere, iyo PCB inowana goridhe layer. Bhodhi racho rakanyikwa mubhati regoridhe. Ndarama inotsiva imwe nickel iri pamusoro. Ndarama inomisa nickel kubva mukuora uye inoita kuti musodha zvive nyore.
The gold layer inogadzirwa kukora chaiko. Kazhinji inokora 1.2 kusvika 2.5 µm. Izvi zvinoita kuti kutengesa kuve nyore uye kunopa nzvimbo yakatsetseka yezvikamu zvidiki. Ndarama inoitawo kuti PCB iite seinopenya uye inyanzvi.
Kuvimbiswa Kwemhando mu ENIG
Kuongorora kwemhando kwakakosha zvakanyanya mukuita kwe ENIG. Ivo vanoita shuwa kuti PCB inoshanda nemazvo uye inogara kwenguva refu. Miedzo yakasiyana inoshandiswa kutarisa kunaka:
