Njengeenjineli, siye sacinga ngazo zonke iindlela ezinokuthi zisilele ngayo inkqubo, kwaye xa sele isilele, sikulungele ukuyilungisa. Ukuphepha iimpazamo kubaluleke kakhulu kuYilo lwe-PCB. Ukuthatha indawo yeBhodi yeSekethe eyonakalisiweyo ebaleni kunokuba yindleko, kwaye ukungoneliseki kwabathengi kuhlala kubiza kakhulu. Esi sisizathu esibalulekileyo sokugcina sikhumbula izizathu ezithathu eziphambili zomonakalo we-PCB kwinkqubo yoyilo: ukuvelisa iziphene, izinto zokusingqongileyo kunye noyilo olungaphelelanga. Nangona ezinye zezi zinto zinokuphulukana, izinto ezininzi zinokuncitshiswa ngexesha lesigaba soyilo. Kungenxa yoko le nto ukucwangciswa kwemeko embi ngexesha lenkqubo yoyilo kunokunceda iBhodi yakho Yenza isixa esithile sokusebenza.

I-01 ivelisa isiphene semveliso

Enye yezizathu eziqhelekileyo zomonakalo weBhodi yeBhodi yeBhodi yeBhodi ngenxa yokwenza iziphene zemveliso. Ezi ziphene zinokuba nzima ukufumana, kwaye kunzima ngakumbi ukulungisa kwakufunyenwe. Nangona abanye babo banokulwa, abanye kufuneka bahlawulwe ngumvelisi wesivumelwano (cm).

I-02 ye-Envirtor

Enye into eqhelekileyo yoyilo lokuyila i-PCB yindawo yokusebenza. Ke ngoko, kubaluleke kakhulu ukuyila iBhodi yeSiphaluka kwaye imeko ngokwendawo esiya kusebenza kuyo.

Ubushushu: Ibhodi yesekethe ivelise ubushushu kwaye ihlala ityhilwa bubushushu ngexesha lokusebenza. Qwalasela ukuba uyilo lwe-PCB luya kujikeleza i-PCB ebiyelweyo, iveliswe lilanga, okanye amaqondo obushushu angaphandle, okanye afumane ubushushu obuvela eminye imithombo yolwazi. Utshintsho kubushushu obunokuchitha uhlangatye kwiTortor, isiseko kunye nendawo yokuhlala. Ukuba isekethe yakho iphantsi kwamaqondo obushushu aphezulu, kusenokufuneka ufundele ngokwamacandelo eHole, oqhele ukuqhuba ubushushu obungaphezulu kune-SMT.

Uthuli: Uthuli luyinto ye-elektroniki iimveliso ze-elektroniki. Qinisekisa ukuba ityala lakho linenqanaba le-IP elichanekileyo kunye / okanye likhetha izinto ezinokuthi ziphathe amanqanaba othuli alindelekileyo kwindawo yokusebenza kunye / okanye asebenzise iingubo ezifanayo.

Ukufuma: umzukisi ubeka isoyikiso esikhulu kwizixhobo ze-elektroniki. Ukuba uyilo lwe-PCB lusebenza kwindawo enomswakama apho ubushushu butshintsha ngokukhawuleza, umswakama buya kuphumelela emoyeni kwisekethe. Ke ngoko, kubalulekile ukuqinisekisa ukuba iindlela zokufuma zifakwe kuwo wonke umsebenzi webhodi yesekethe nangaphambi kofakelo.

Ukuguquka komzimba: Kukho isizathu sentengiso ye-elektroniki eqinileyo ukuba abantu bayiphosa elutyeni okanye kwikhonkrithi. Ngexesha lokusebenza, izixhobo ezininzi ziphantsi kothusi okanye inyikima. Kuya kufuneka ukhethe iikhabhathi, iibhodi zesekethe kunye namacandelo esekwe kwintsebenzo yoomatshini ukusombulula le ngxaki.

I-03 yoyilo olungathethiyo

Into yokugqibela yoyilo lweBhodi yePCB yoyilo ngexesha lokusebenza yeyona ibaluleke kakhulu: uyilo. Ukuba injongo ye-injineli ayikhethwanga ngokuthe ngqo ukuhlangabezana neenjongo zayo zomsebenzi; Ukubandakanya ukuthembeka kunye nobomi obude, oku kukufikeleleka nje. Ukuba ufuna iBhodi yakho yeSekeji ihlale ixesha elide, qiniseka ukuba ukhetha izinto kunye nezixhobo, zazise iBhodi yeSiphako, kwaye uqinisekise uyilo ngokweemfuno ezithile zoyilo.

Ukhetho lwecandelo: Ixesha elingaphezulu, amacandelo aya kusilela okanye ayeke ukuveliswa; Nangona kunjalo, ayamkelekanga koku kusilela kwenzeke ngaphambi kokuba ubomi obulindelekileyo beBhodi buyaphelelwa. Ke ngoko, ukhetho lwakho kufuneka luhlangabezane neemfuno zomsebenzi wendalo kwaye ube nomjikelo wobomi bobomi obaneleyo ngexesha lokujikeleza kobomi obulindelekileyo kwiBhodi yeSiphaluka.

Ukukhethwa kwezinto Ukuveza ubushushu, ukuhamba ngebhayisikile, ukukhanya kwe-therraviolet, kunye noxinzelelo loomatshini kunokubangela ukonakaliswa kwesekethe kunye nokungaphumli kwangaphambili. Ke ngoko, kufuneka ukhethe izinto zebhodi yebhodi eneenkcukacha ezilungileyo zokushicilela ngokohlobo lwebhodi yesekethe. Oku kuthetha ukuthathela ingqalelo iipropathi zezinto ezibonakalayo kunye nokusebenzisa ezona zinto zingasebenzi zilungele uyilo lwakho.

Uyilo loyilo lwePCB: Uyilo loyilo lwePCB lusenokuba ngunobangela wokungaphumeleli kwebhodi yesiphaluka ngexesha lokusebenza. Umzekelo, imiceli mngeni eyodwa yokubandakanya iibhodi ze-voltage ephezulu; Inqanaba le-IRC eliphakamileyo le-ARC, linokubangela ibhodi yesekethe kunye nomonakalo wenkqubo, kwaye nokubangela ukuba abasebenzi benzekala.

Ukuqinisekiswa koyilo: Eli inokuba lelona nyathelo libalulekileyo ekuveliseni isekethe elithembekileyo. Yenza i-DFM ijongene ne-CM yakho ekhethekileyo. Ezinye ii-CMS zinokugcina ubuchule obuqinileyo kunye nomsebenzi onezinto ezizodwa, ngelixa abanye bengakwazi. Phambi kokuba uqale imveliso, qiniseka ukuba i-CM inakho ukwenza iBhodi yakho yeSekeji ngendlela oyifunayo, eya kuqinisekisa ukuba uyilo oluphezulu lwe-PCB aliyi kusilela.

Akukho nto inomdla wokuthetha ukuba eyona meko imbi kakhulu yokufumana uyilo lwe-PCB. Ukwazi ukuba uyile iBhodi enokuthenjwa, ayiyi kusilela xa iBhodi idluliselwe kumthengi. Khumbula izizathu ezithathu eziphambili zomonakalo we-PCB ukuze ukwazi ukufumana kakuhle iBhodi yeSiphako engaguqukiyo nethembekileyo. Qiniseka ukuba ucwangcisa iziphene zemveliso kunye nezinto zokusingqongileyo ukusuka ekuqaleni, kwaye ugxile kwizigqibo zoyilo zamatyala athile.
