Ni izihe ngaruka z'abagurisha barwanya ibara kuri PCB?

Ubuyobozi bwa PCB ntabwo burenze amabara, nibyingenzi.

Mubyukuri, ibara ryibibaho bya PCB ni ibara rya mask yo kugurisha.Ubwa mbere, umugurisha arwanya arashobora gukumira kugurisha nabi ibice.Icya kabiri, irashobora gutinza ubuzima bwa serivisi yibikoresho, kugirango birinde okiside na ruswa yumuzunguruko.

Niba uzi byinshi kubuyobozi bwa PCB bwa HUAWEI, Ericsson nandi masosiyete manini, uzasanga ibara muri rusange ari icyatsi.Kuberako tekinoroji yicyatsi kibisi kubuyobozi bwa PCB niyo ikuze kandi yoroshye.

Usibye icyatsi, hari amabara menshi ya PCB, nka: cyera, umuhondo, umutuku, ubururu, ibara ryoroheje, ndetse na chrysanthemum, umutuku, umukara, icyatsi kibisi, nibindi. Umweru ni pigment ikenewe kugirango habeho itara kandi amatara.Gukoresha andi mabara ahanini bigamije kuranga ibicuruzwa.PCB ikora ibicuruzwa bya sosiyete kuva R&D kugeza ikuze mubyiciro byose, ukurikije imikoreshereze itandukanye yubuyobozi bwa PCB, akanama gashinzwe ubushakashatsi gashobora gukoresha ibara ry'umuyugubwe, ikibaho cyingenzi kizakoresha umutuku, ikibaho cyimbere cya mudasobwa kizakoresha umukara, byose bigomba gutandukanya no gushyira akamenyetso ku ibara.

PCB ikunze kugaragara cyane ni ikibaho kibisi, kizwi kandi nkamavuta yicyatsi, kandi uyigurisha arwanya wino ifite amateka maremare, ahendutse kandi azwi cyane.Amavuta yicyatsi afite ibyiza byinshi usibye ikoranabuhanga rikuze:

Mugutunganya PCB, kubyara ibicuruzwa bya elegitoronike birimo gukora amasahani no kumurika.Muri iki gihe, hariho inzira nyinshi zo kunyura mucyumba cyumucyo cyumuhondo, kandi icyatsi kibisi PCB gifite ingaruka nziza zo kugaragara mubyumba byumuhondo.Icya kabiri, mubuyobozi bwa SMT PCB, intambwe zo gutobora, kumurika no kugenzura AOI byose bikenera umwanya uhagaze neza na kalibrasi, kandi icyatsi kibisi PCB nibyiza mukumenyekanisha ibikoresho.

Bimwe mubikorwa byo kugenzura biterwa no kwitegereza abakozi (ubu benshi muribo bakoresha ikizamini cyo kuguruka aho gukoresha imirimo y'amaboko).Bakomeza kwitegereza ku kibaho munsi yumucyo ukomeye, kandi ibyatsi bibisi kumaso ni bike.Icyatsi kibisi PCB cyangiza ibidukikije, kandi nyuma yubushyuhe bwo hejuru, ntibisohora imyuka yubumara.

Andi mabara ya PCB, nk'ubururu n'umukara byanditseho cobalt na karubone.Kuberako bafite intege nke ziyobora, harikibazo cyumuzunguruko mugufi.

Nka kibaho cyirabura, birashoboka cyane ko bitera itandukaniro ryamabara bitewe nibikorwa nibibazo byibanze mubikorwa, biganisha ku gipimo kinini cya PCB.Guhindura inzira yumukara wumuzingi ntibyoroshye kubimenya, bizongera ingorane zo kubungabunga no gukemura nyuma.Kubwibyo, benshiAbakora inteko ya PCBntabwo yakoresheje ikibaho cyumukara PCB.Ndetse no mubijyanye ninganda za gisirikare no kugenzura inganda, ibicuruzwa bifite ubuziranenge bwo hejuru nabyo bikoresha ikibaho kibisi PCB.

Ni izihe ngaruka z'abagurisha kurwanya ibara rya wino ku kibaho cya PCB?

Kubicuruzwa byarangiye, ingaruka za wino zitandukanye kurubaho zigaragarira cyane mubigaragara.Kurugero, icyatsi kirimo icyatsi kibisi, icyatsi kibisi, icyatsi kibisi, icyatsi kibisi nibindi.Niba ibara ryoroheje cyane, Nyuma yo gucomeka umwobo, isura yubuyobozi izagaragara.Bamwe mubakora bafite wino mbi, resin hamwe n irangi ryibara ryibara, kandi hazabaho ibisebe nibindi bibazo Menya ihinduka ryamabara make.Kubicuruzwa bitarangiye, ingaruka zigaragarira cyane cyane murwego rugoye mubikorwa.Ibi bibazo biragoye kubisobanura.Irangi ryamabara atandukanye rifite uburyo butandukanye bwo gusiga amabara, harimo gutera amashanyarazi ya electrostatike, gutera no gucapa ecran, kandi igipimo cya wino nacyo kiratandukanye.Niba hari ikosa rito, ibara rizagenda nabi.

Nubwo ibara rya wino ridafite ingaruka ku kibaho cya PCB, ubunini bwa wino bugira uruhare runini kuri impedance.Cyane cyane kumazi ya zahabu, igenzura ubunini bwa wino cyane.Irangi ry'umutuku, umubyimba n'ibibyimba byoroshye kugenzura, kandi wino itukura irashobora gupfukirana inenge zimwe zumuzunguruko, bikaba byiza cyane mubigaragara, ariko ibibi nuko igiciro gihenze.Iyo ushushanya, umutuku n'umuhondo bigaragarira cyane, kandi byera nibyo bibi kugenzura.

Muncamake, ibara ntirigira ingaruka kumikorere yubuyobozi bwarangiye, kandi rifite ingaruka nke kuriSMT PCBikibaho nandi masano.Mu gishushanyo cya PCB, kugenzura neza buri kantu muri buri murongo ni urufunguzo rwubuyobozi bwiza bwa PCB.Amabara atandukanye yubuyobozi bwa PCB, cyane cyane kubireba neza ibicuruzwa, ntabwo dushimangira ibara nkikintu cyingenzi mugutunganya PCB.
