Njengeenjineli, siye sacinga ngazo zonke iindlela enokuthi le nkqubo isilele ngayo, yaye yakuba isilele, sikulungele ukuyilungisa. Ukuphepha iimpazamo kubaluleke ngakumbi kuyilo PCB. Ukutshintsha ibhodi yesekethe eyonakaliswe kwintsimi kunokubiza, kwaye ukunganeliseki kwabathengi kudla ngokubiza kakhulu. Esi sizathu esibalulekileyo sokukhumbula izizathu ezithathu eziphambili zomonakalo we-PCB kwinkqubo yoyilo: iziphene zokuvelisa, izinto zokusingqongileyo kunye noyilo olungonelanga. Nangona ezinye zezi zinto zinokungalawuleki, izinto ezininzi zinokuncitshiswa ngexesha lesigaba soyilo. Yingakho ukucwangcisa imeko embi ngexesha lenkqubo yoyilo kunokunceda ibhodi yakho yenze inani elithile lomsebenzi.
01 Isiphene sokwenziwa kwemveliso
Esinye sezizathu eziqhelekileyo zomonakalo webhodi yoyilo lwePCB kungenxa yeziphene zokuvelisa. Ezi ziphene kunokuba nzima ukuzifumana, kwaye kunzima ngakumbi ukuzilungisa xa zifunyenwe. Nangona ezinye zazo zinokuyilwa, ezinye kufuneka zilungiswe ngumenzi wekhontrakthi (CM).
02 factor yezendalo
Omnye unobangela oqhelekileyo wokusilela kuyilo lwePCB yindawo yokusebenza. Ngoko ke, kubaluleke kakhulu ukuyila ibhodi yesekethe kunye necala ngokuhambelana nendawo eya kusebenza kuyo.
Ubushushu: Iibhodi zeesekethe zivelisa ubushushu kwaye zihlala zisesichengeni sobushushu ngexesha lokusebenza. Cinga ukuba uyilo lwePCB luyakujikeleza na kwindawo ebiyelweyo, lube sesichengeni selanga namaqondo obushushu angaphandle, okanye lufunxe ubushushu obuvela kweminye imithombo ekufutshane. Ukutshintsha kweqondo lobushushu kunokuqhekeka amajoyinti e-solder, izinto ezisisiseko kunye nezindlu. Ukuba isekethe yakho ixhomekeke kumaqondo obushushu aphezulu, kunokufuneka ukuba ufunde ngemingxunya, edla ngokuqhuba ubushushu obuninzi kune-SMT.
Uthuli: Uthuli sisiphelo seemveliso ze-elektroniki. Qinisekisa ukuba ityala lakho linomlinganiselo ochanekileyo we-IP kunye/okanye ukhethe amacandelo anokusingatha amanqanaba othuli alindelekileyo kwindawo yokusebenza kunye/okanye asebenzise ii-coatings ezihambelanayo.
Ukufuma: Ukufuma kuyingozi enkulu kwisixhobo sombane. Ukuba uyilo lwePCB luqhutywa kwindawo efumileyo kakhulu apho ubushushu buguquka ngokukhawuleza, ukufuma kuya kuxinana ukusuka emoyeni ukuya kwisekethe. Ngoko ke, kubalulekile ukuqinisekisa ukuba iindlela zobungqina bomswakama zifakwe kwisakhiwo sebhodi yesiphaluka nangaphambi kokufakwa.
Ukungcangcazela komzimba: Kukho isizathu sentengiso eyomeleleyo ye-elektroniki yokuba abantu bazijule ematyeni okanye kwimigangatho yekonkile. Ngexesha lokusebenza, izixhobo ezininzi ziphantsi komothuko womzimba okanye ukungcangcazela. Kufuneka ukhethe iikhabhinethi, iibhodi zeesekethe kunye namacandelo asekelwe ekusebenzeni koomatshini ukusombulula le ngxaki.
03 Uyilo olungangqalanga
Into yokugqibela yomonakalo webhodi yoyilo lwePCB ngexesha lokusebenza yeyona nto ibalulekileyo: uyilo. Ukuba injongo yenjineli ayikokuhlangabezana neenjongo zayo zokusebenza; kubandakanywa ukuthembeka kunye nokuphila ixesha elide, oku kulula ukufikelela. Ukuba ufuna ukuba ibhodi yakho yesiphaluka ihlale ixesha elide, qiniseka ukuba ukhethe amacandelo kunye nezinto eziphathekayo, ubeke ibhodi yesiphaluka, kwaye uqinisekise ukuyila ngokweemfuno ezithile zoyilo.
Ukukhetha icandelo: Ngokuhamba kwexesha, amacandelo aya kusilela okanye ayeke ukuvelisa; nangona kunjalo, akwamkelekanga ukuba oku kusilela kwenzeke phambi kokuba ubomi obulindelekileyo bebhodi buphelelwe lixesha. Ngoko ke, ukhetho lwakho kufuneka luhlangabezane neemfuno zokusebenza kwendawo yayo kwaye lube nomjikelo wobomi becandelo elaneleyo ngexesha lomjikelo wobomi obulindelekileyo bebhodi yesekethe.
Ukukhetha izinto eziphathekayo: Kanye njengokuba ukusebenza kwamacandelo kuya kusilela ekuhambeni kwexesha, kuya kuba njalo nokusebenza kwezinto. Ukubonakaliswa kobushushu, ukuhamba ngebhayisikile eshushu, ukukhanya kwe-ultraviolet, kunye noxinzelelo lomatshini kunokubangela ukuthotywa kwebhodi yesekethe kunye nokusilela kwangaphambi kwexesha. Ngoko ke, kufuneka ukhethe izinto zebhodi yesiphaluka kunye nemiphumo emihle yokushicilela ngokohlobo lwebhodi yesekethe. Oku kuthetha ukuqwalasela iipropati eziphathekayo kunye nokusebenzisa ezona zinto zingasebenziyo ezifanelekileyo kuyilo lwakho.
Uyilo loyilo lwePCB: Uyilo loyilo lwePCB olungacacanga lusenokuba ngunobangela osisiseko wokusilela kwebhodi yesekethe ngexesha lokusebenza. Ngokomzekelo, imingeni ekhethekileyo yokungabandakanyi iibhodi eziphezulu ze-voltage; ezifana nesantya sokulandelela i-arc ephezulu, inokubangela ibhodi yesekethe kunye nomonakalo wenkqubo, kwaye ibangele nokwenzakala kubasebenzi.
Ukuqinisekiswa koyilo: Oku kunokuba lelona nyathelo libalulekileyo ekuveliseni isekethe ethembekileyo. Yenza iitshekhi zeDFM kunye neCM yakho ethile. Ezinye ii-CM zinokugcina ukunyamezela okuqinileyo kunye nokusebenza ngezinto ezikhethekileyo, ngelixa ezinye zingenako. Ngaphambi kokuba uqale ukuvelisa, qiniseka ukuba i-CM inokuvelisa ibhodi yakho yesekethe ngendlela ofuna ngayo, eya kuqinisekisa ukuba uyilo oluphezulu lwePCB aluyi kusilela.
Ayinamdla ukucinga eyona meko imbi kakhulu yoyilo lwePCB. Ukwazi ukuba uyile ibhodi ethembekileyo, ayiyi kusilela xa ibhodi ithunyelwa kumthengi. Khumbula izizathu ezithathu eziphambili umonakalo PCB uyilo ukuze ukwazi ukufumana ngokutyibilikayo ibhodi yesekethe engaguqukiyo. Qinisekisa ukucwangcisa iziphene zokuvelisa kunye nezinto zokusingqongileyo ukusuka ekuqaleni, kwaye ugxininise kwizigqibo zoyilo kwiimeko ezithile.
