Izvo Zvakanakira uye Zvishandiso zveGoridhe Plated PCBs

Goridhe Finger PCB

Munyika yakaoma uye inogara ichishanduka yemagetsi, maPCB anoumba musana wezvishandiso zvisingaverengeki. Pakati pekufambira mberi kwakasiyana muPCB tekinoroji, maPCB akaiswa goridhe akabuda semhinduro yakamira, ichipa musanganiswa wekuvimbika, kuita, uye nemazvo. Ichi chinyorwa chine chinangwa chekuongorora iyo yakawanda nyika yeaya akasarudzika maPCB.

Chii chinonzi Gold Plating PCBs

Ndarama yakapfekwa maPCBs anoreva maPCB ane chitete chegoridhe chakaiswa kune zvikamu zvenzvimbo yavo, kunyanya mapadhi nemabatiro. Kuiswa kwegoridhe uku hakusi kwekunaka chete; inoita basa rakakosha mukushanda kwePCB. Nhoroondo, kushandiswa kwegoridhe muPCB kwave kuchifambiswa nesimbi yakanakisa conductive zvivakwa uye kuramba kwayo kune oxidation uye corrosion. Hunhu uhu hunoita kuti goridhe ive sarudzo yakanaka yekuchengetedza kushanda kwenguva refu munzvimbo dzakasiyana siyana.

Maitiro ekuisa goridhe kumaPCB, anowanzo kunzi goridhe plating, anosanganisira akati wandei akaomesesa matanho ayo anovimbisa kusimba uye kushanda kwePCB muzvikamu zvemagetsi. Pamusoro pezvo, kune marudzi akasiyana egoridhe plating anoshandiswa muPCBs, imwe neimwe iine yakasarudzika maitiro uye mashandisiro. Kunzwisisa mhando idzi kwakakosha pakusarudza iyo chaiyo PCB kune chaiyo application.

Iyo Goridhe Plating Maitiro muPCBs

Maitiro ekuputira goridhe paPrinted Circuit Boards (PCBs) chinhu chakakosha chinopa mabhodhi aya neayo akasiyana. Kunzwisisa maitiro aya kunopa nzwisiso yekuti nei goridhe rakaputirwa PCBs richikosheswa mumagetsi.

1. Kugadzirira Kwepamusoro

Kuchenesa uye Kutsvedza: Pamberi pekuputirwa goridhe, iyo PCB yepamusoro inofanirwa kunyatsocheneswa uye kutsetseka. Chero zvinosvibisa kana zvisizvo zvinogona kukanganisa kunamatira uye kunaka kweiyo goridhe plating.
Micro-etching: Iyo micro-etching process inowanzo shandiswa kukoromoka zvishoma pasi, ichisimbisa kunamatira kwegoridhe kune iri pasi pendarira.

2. Base Layer Plating

Nickel Plating: Muzviitiko zvakawanda, chidimbu che nickel chinotanga kuiswa paPCB. Nickel inoshanda semhinganidzo kudzivirira goridhe kuti risapararire mumhangura uye inopa nzvimbo yekuti goridhe rinamate kwariri.
Kufanana uye Hukobvu: Iyi nickel layer inofanirwa kuve yakafanana muhukobvu uye isina hurema kuti ive nechokwadi chemhando uye hupenyu hurefu hwegoridhe replating.

3. Goridhe Plating

Pre-Plating Kugadzirira

Kucheneswa Kwepamusoro: Danho rekutanga rinosanganisira kucheneswa kwePCB kumeso kubvisa chero zvinosvibisa. Izvi zvinowanzoitwa uchishandisa akatevedzana emakemikari ekugezera anobvisa pamusoro pemafuta, tsvina, uye oxidation zvigadzirwa.
Microscopic Surface Etching: Kutevera kucheneswa, yakapfava asidhi mhinduro inowanzo shandiswa kuseta pamusoro. Iyi nzira inogadzira chimiro chakakanganisika padanho remicroscopic, iyo inobatsira mukunamira kwezvikamu zvesimbi zvinotevera.

Nickel Underlayer Application

Electroless Nickel Plating: Isati yaiswa goridhe, musara we nickel unoiswa. Izvi zvinowanzoitwa uchishandisa electroless plating process, iyo, kusiyana neyechinyakare electroplating, haidi yemagetsi ikozvino.
Barrier Properties yeNickel: Nickel inoshanda sechipinganidzo kudzivirira kupararira kwemhangura mudura regoridhe. Izvi zvakakosha sezvo kupararira kwemhangura kunogona kutungamira kune oxidation, kukanganisa magetsi ePCB.

Yakadzama Goridhe Plating Maitiro

Kunyudza Goridhe Plating: Iyo chaiyo goridhe plating inowanzoitwa uchishandisa kunyudza maitiro. PCB inonyudzwa mubhavhu rine munyu wegoridhe nemamwe makemikari. Kuburikidza nekuchinja kwekuita, chidimbu chitete chegoridhe chinoiswa pane nickel layer.
Ukobvu Kudzora: Kudzora ukobvu hwegoridhe layer kwakakosha. Kune akawanda maapplication, iyo goridhe layer inochengetwa yakatetepa, kazhinji ingori mashoma mamicroinches gobvu. Izvi zvakakwana kupa zvinodiwa pamusoro pezvivakwa pasina kudhura zvakanyanya.

Post-Plating Kuongorora uye Kudzora Kwemhando

Kuyerwa kwehukobvu: Mushure mekuputira, ukobvu hwegoridhe rinoyerwa uchishandisa matekiniki akaita seX-ray fluorescence kana coulometric ukobvu kuyedzwa.
Adhesion Testing: Kuti ive nechokwadi chekuti goridhe rinonamira zvakanaka kune nickel, bvunzo dzakasiyana dzekunamatira, senge tepi bvunzo, dzinoitwa.

Zvakanakira Gold Plated PCBs

Ndarama yakaputirwa maPCB haangozivikanwi nekuda kwekunaka kwawo; vanopa huwandu hwezvakanakira izvo zvinoita kuti vatsvake zvakanyanya muindasitiri yemagetsi. Ichi chikamu chinoongorora mabhenefiti aya, kuratidza maitiro avanoita mamwe maPCB anopedza.
