Kwimveliso kunye nokulungiswa kwe-PCBA ye-AutoMotive, ezinye iibhodi zesekethe kufuneka zidityaniswe nobhedu. Ukudibana kobhedu kunokunciphisa ngokufanelekileyo impembelelo yeemveliso zokulungisa i-SMT patch ekuphuculeni ubuchule bokuphazamiseka kunye nokunciphisa indawo yeloop. Iziphumo zayo ezihle zinokusetyenziswa ngokupheleleyo kukhuseleko lwe-SMT. Nangona kunjalo, zininzi izinto ekufuneka ziqwalaselwe ngexesha lenkqubo yobhedu. Makhe ndizise iinkcukacha zenkqubo yokuqhuba ye-PCBA yoshicilelo locwangco.
一. Inkqubo yokuThumela kobhedu
I-1. Ngaphambi kokugada kocwaba kobhedu olusemthethweni, ibhodi ye-PCB kufuneka ihlulwe, kubandakanya ukususwa, ukususwa, ukucoca kunye nokugudla komgangatho webhodi kunye nokulalela isiseko esihle sobhedu.
I-2. Ukubetha kocofe ucofe: ukuthantamisa ulwelo lolwelo olungenamkhethe kumphezulu weBhodi yeSheet ukuya kwi-shemil idibanise ifilimu yobhedu yenye yeendlela eziqhelekileyo zokubekwa kobhedu. Inzuzo kukuba ubukhulu kunye nokufana kwefilimu yobhedu kunokulawulwa kakuhle.
I-3. Ukubekwa kocaphu ngoomatshini: Umphezulu webhodi yesekethe ugutyungelwe ngumaleko we-foil yobhedu ngokuqhubekeka koomatshini. Leyo nenye yeendlela zokubeka kobhedu, kodwa iindleko zemveliso ziphezulu kunomgaqo wobhedu, ukuze ukhethe ukuzisebenzisa ngokwakho.
I-4. Ukuhamba kobhedu kunye nokulelisa: linyathelo lokugqibela lenkqubo yobhedu. Emva kokugqitywa komgaqo-nkqubo, i-foil yobhedu kufuneka icinezelwe kumphezulu webhodi yesekethe ukuze iqinisekise ukuba indibaniselwano epheleleyo, ngaloo ndlela iqinisekisa ukudityaniswa ngokupheleleyo, oko ke kukuqinisekisa ukuqhutywa kweMveliso kunye nokuthembeka kwemveliso.
二. Indima ye-Copper
1. Nciphisa ukudinwa kwe-wire yomhlaba kunye nokuphucula ubuchule bokuphazamiseka;
2. Nciphisa i-voltage hla kwaye uphucule ukusebenza kakuhle kwamandla;
3. Qhagamshela kwi-wire yomhlaba ukunciphisa indawo yeloop;
三. Amanyathelo okhuseleko lokugalela ubhedu
1. Sukugalela ubhedu kwindawo evulekileyo ye-wiring kwiBhodi ephakathi yeBhodi yeZininzi.
I-2. Unxibelelwano lwamanqaku amabini kwizizathu ezahlukeneyo, le ndlela kukunxibelelana nge-0-ofisi ka-Ohm okanye ubuhlalu obukhulu okanye izikhuselo.
3. Xa uqala uyilo oluqhelekileyo, ucingo oluphantsi kufuneka lubekwe kakuhle. Awunakho ukuthembela kwi-Vias emva kokuthulula ubhedu ukuba luphelise izikhonkwane zomhlaba ezingafunekiyo.
4. Galela ubhedu kufutshane ne-crystal oscillator. I-crystal oscillator kwisekethe ingumthombo oPhezulu we-Right. Indlela yokuthulula i-terstillator ejikeleze i-crystal oscillator, emva koko ibe yindawo yeqokobhe le-crystal oscillator ngokwahlukeneyo.
5. Qinisekisa ubukhulu kunye nokufana kwe-copper clad. Ngokwesiqhelo, ubukhulu bobhedu lwecala luphakathi kwe-1 ukuya kwaphela. I-copper yamacala e-copper enqabileyo okanye incinci kakhulu iya kuchaphazela umgangatho wokusebenza okuqhubayo kunye nomgangatho wokudluliselwa kwePCB. Ukuba ungqameko lobhedu alulingani, luza kubangela ukuphazamiseka kunye nokuphulukana neBhodi yeSekethe, kuchaphazela intsebenzo ye-PCB.
