Ukulawula iindleko zePCB kufuna uyilo lwebhodi yokuqala engqongqo, ugqithiso olungqongqo lweenkcukacha zakho kubaboneleli, kunye nokugcina ubudlelwane obungqongqo nabo.
Ukukunceda, siqokelele iingcebiso ezisi-8 kubathengi kunye nababoneleli onokuzisebenzisa ukunciphisa iindleko ezingeyomfuneko xa uvelisa iiPCB.
1.Qwalasela ubungakanani kwaye udibane nomenzi
Kwanangaphambi kwesigaba sokugqibela soyilo lobunjineli bobugcisa, iincoko nababoneleli bakho zinokukuvumela ukuba uqalise iingxoxo kwaye uqonde imingeni enxulumene nemveliso yeprojekthi yakho.
Ukususela ekuqaleni, qwalasela imiqulu yakho ngokuqokelela ulwazi oluninzi onokuthi ulufumane kubaboneleli bakho: izinto ezikhethekileyo zemathiriyeli, landelela iinkcukacha zobugcisa, okanye ukunyamezela ibhodi. Ukukhetha okungalunganga kunokukhokelela kwisixa esikhulu senkcitho kwaye kuvelise iindleko ezingeyomfuneko eziye zamiselwa kwangoko kwisigaba soyilo. Ngoko zinike ixesha lokuxoxa kwaye uvavanye iingenelo kunye nezingeloncedo kuzo zonke izisombululo ezikhoyo kuwe.
2.Nciphisa ubunzima bebhodi yesekethe
Le yeyona ndlela ilula yokunciphisa iindleko zePCB: khulisa ukubekwa kwecandelo lebhodi ngoyilo olulula. Unokunciphisa iindleko ngokungasebenzisi naziphi na iifom ezinzima kunye nokunciphisa ubungakanani, kodwa qaphela, kule meko khumbula ukushiya indawo eyaneleyo phakathi kwendawo nganye.
Iifom ezintsonkothileyo, ngakumbi ezo zingaqhelekanga, zonyusa iindleko. Ukusikwa kwe-PCB yangaphakathi kuthintelwe kakuhle ngaphandle kokuba ifuneka kwindibano yokugqibela. Umvelisi ukhupha i-invoyisi eyongezelelweyo kuzo zonke izithintelo ezongezelelweyo. Iinjineli ezininzi zikhetha inkangeleko yokuqala, kodwa kwihlabathi lenene, lo mahluko awuchaphazeli umfanekiso woluntu kwaye awongezi naluphi na umsebenzi.
3.Chaza ubungakanani obuchanekileyo kunye nobukhulu
Ifomathi yebhodi inempembelelo ephezulu kwinkqubo yocingo: ukuba i-PCB incinci kwaye inzima, ixesha elininzi kunye nomzamo uya kufuneka ukuba umhlanganisi ayigqibe. Ubukhulu obubambene kakhulu buya kuhlala bubiza. Ngoko kusoloko kuyinto elungileyo ukugcina indawo, sincoma ukuba singayinciphisi ngaphezu kwemfuneko ukuphepha imisebenzi emininzi kwibhodi enye.
Kwakhona, khumbula ukuba iifom ezintsonkothileyo zinempembelelo kwixabiso: isikwere okanye i-PCB exande iya kukuvumela ukuba ugcine ulawulo.
Okukhona ubuninzi bePCB busanda, kokukhona ixabiso lokwenziwa liphezulu liya kuba…kwithiyori nakanjani! Inani leeleya ozikhethayo lichaphazela ibhodi yesekethe nge-vias (uhlobo kunye nobubanzi). Ukuba ibhodi ibhityile, iindleko zebhodi zizonke zinokuncitshiswa, kodwa imingxuma emininzi inokufuneka, kwaye abanye oomatshini ngamanye amaxesha abanakusetyenziswa ngeePCB ezibhityileyo. Ukuthetha nomthengisi wakho kwangethuba kuya kukunceda wonge imali!
4.Ubungakanani obuchanekileyo bemingxuma kunye namakhonkco
Iipads ezinkulu kunye nemingxuma zezona zilula ukwenza kuba azifuni oomatshini abachaneke kakhulu. Kwelinye icala, ezincinci zifuna ulawulo olubuthathaka kakhulu: zithatha ixesha elide ukwenziwa kwaye oomatshini bayabiza kakhulu, nto leyo eyonyusa kakhulu iindleko zakho zokuvelisa iPCB.
5.Nxibelelana ngedatha ngokucacileyo kangangoko kunokwenzeka
Iinjineli okanye abathengi abaodola ii-PCB zabo kufuneka bakwazi ukuthumela isicelo sabo ngokucacileyo kangangoko kunokwenzeka, kunye namaxwebhu apheleleyo (iifayile zeGerber ezibandakanya zonke iileya, i-impedance checking data, ukupakishwa okuthe ngqo, njl.njl.): ngaloo ndlela ababoneleli abanasidingo sokutolika. kunye namanyathelo okulungisa atya ixesha kunye neendleko ezinkulu aya kuphetshwa.
Xa ulwazi lungekho, ababoneleli kufuneka bakwazi ukuqhagamshelana nabathengi babo, bachithe ixesha elixabisekileyo elinokusetyenziswa kwezinye iiprojekthi.
Okokugqibela, amaxwebhu acacileyo enza kube nokwenzeka ukuchonga ukusilela okunokwenzeka ukuphepha ukuqhekeka kunye nesiphumo sokungavisisani kwabathengi nababoneleli.
6.Optimise paneling
Ukusasazwa okugqwesileyo kweesekethe kwiphaneli kukwadlala indima ephambili: yonke imilimitha yendawo esetyenzisiweyo ivelisa iindleko, ngoko ke kungcono ukungashiyi indawo enkulu phakathi kweesekethe ezahlukeneyo. Khumbula ukuba amanye amacandelo anokudibana kwaye afune indawo eyongezelelweyo. Ukuba ipaneli iqinile kakhulu ngamanye amaxesha ifuna i-soldering yezandla ekhokelela ekunyukeni kwamaxabiso.
7.Khetha uhlobo olululo lokugqitha
Iindlela zokungena zifikeleleka zixabiso eliphantsi, ngelixa imingxunya engaboniyo okanye engeneyo ivelisa iindleko ezongezelelweyo. Ezi zifuneka kuphela kwiibhodi eziyinkimbinkimbi, ezixinzelelekileyo okanye eziphezulu.
Inani le-vias kunye nohlobo lwazo lunempembelelo kwiindleko zemveliso. Iibhodi ezininzi zidla ngokufuna imingxunya emincinci edayamitha.
8.Cinga ngokutsha imikhwa yakho yokuthenga
Nje ukuba uzifezekise zonke iindleko zakho, unokuphinda ujonge amaxesha okuthenga kwakho kunye nenani. Ngokucwangcisa iiodolo unokonga imali eninzi. Ngokomzekelo, ukuba uthengela ikhulu leesekethe ezingamashumi amabini ngonyaka, unokugqiba ukutshintsha i-frequency ngoku-odola kuphela kahlanu ngonyaka.
Qaphela ukuba ungazigcini ixesha elide nangona ngenxa yomngcipheko wokuphelelwa yisikhathi.
Ngoku uyazi ukuba ungenza njani iindleko zePCB yakho kangangoko. Qaphela, kuba kwezinye iimeko, ukwenza ukonga kwindalo yesekethe eprintiweyo ayinakuhlala ilungile. Nokuba iindleko zincitshisiwe kwimveliso yokuqala, zinokubiza kakhulu ekuhambeni kwexesha: awunakuze uqiniseke ukuba akusayi kufuneka utshintshe iibhodi rhoqo… Kuya kufuneka kwakhona ulawule ukunganeliseki kwabathengi kwaye ufumane isisombululo esitsha kamva. ukuphepha ezi lahleko.
Naluphi na ukhetho olwenzayo, ekugqibeleni, esona sisombululo silungileyo sokulawula iindleko kukuhlala uxoxa ngezinto nababoneleli bakho. Baya kuba nako ukukunika ulwazi olufanelekileyo noluchanekileyo ukuhlangabezana neemfuno zakho. Banokukunceda ukuba ulindele iingxaki ezininzi onokujamelana nazo kwaye ziya kongela ixesha elixabisekileyo.
