Ngophuhliso olukhawulezayo lweshishini lombane, iibhodi zePCB ziye zaba yinxalenye eyimfuneko yezixhobo ezahlukeneyo zombane.Nokuba kubathengi be-elektroniki, i-elektroniki yeemoto, okanye kwezonyango, kwimizi-mveliso kunye namanye amacandelo, ukusetyenziswa kweePCB kubaluleke kakhulu.Iibhodi zePCB Ukwenziwa ngokwezifiso kunye nemveliso yobuninzi zibalulekile ekuqinisekiseni ukusebenza kwemveliso kunye nomgangatho.Ke, makhe sifunde malunga nezilumkiso zokwenza ngokwezifiso ibhodi yePCB kunye nemveliso yobuninzi.
一、Amalungiselelo apheleleyo phambi koyilo
Phambi kokwenza ngokwezifiso kunye nokuveliswa kweebhodi zePCB, uyilo olwaneleyo kunye nocwangciso ngamanyathelo ayimfuneko.Abaqulunqi kufuneka bacacise injongo yebhodi yesekethe, iintlobo zezixhobo ze-elektroniki ezifuna ukuqhutyelwa, kunye nemigangatho yokusebenza elindelekileyo.Uphando lwemarike ngaphambi koyilo nalo lubaluleke kakhulu.Inokunceda abaqulunqi baqonde itekhnoloji entsha, izixhobo ezintsha kunye neenkqubo ezintsha kwimarike ukuze bahlangabezane ngcono neemfuno zemveliso kunye nolawulo lweendleko.
二 、 Khetha imathiriyeli efanelekileyo
Ukusebenza kwebhodi ye-PCB kuxhomekeke kumlinganiselo omkhulu kwizinto ezikhethiweyo zesiseko kunye nezixhobo zobhedu ezifake i-laminate.Izinto ezisisiseko eziqhelekileyo ziquka i-FR-4, i-CEM-1, njl njl. izicelo frequency, high-frequency izinto ezine-dielectric ephantsi rhoqo kunye nelahleko ephantsi kufuneka kukhethwe ukunciphisa ilahleko ngexesha lokuhanjiswa komqondiso.
三、Ubeko oluchanekileyo kunye nendlela
Abaqulunqi kufuneka baphephe imigca yesignali yesantya esiphezulu emide kakhulu okanye enqamlezayo ukunciphisa ukuphazamiseka komqondiso kunye nokulibaziseka kokudluliselwa.Uyilo lonikezelo lwamandla kunye neengcingo zomhlaba kufuneka kwakhona kucwangciswe ngokufanelekileyo ukuqinisekisa ukunikezelwa kombane wesekethe ezinzileyo kwaye kuthintelwe ingxolo yokubonelela umbane.Ngexesha lenkqubo yoyilo, isoftware yoyilo lwePCB yobuchwephesha, efana noMyili weAltium, iCadence, njl.
四、Uvavanyo lwePrototype kunye nokuqinisekiswa
Ngaphambi kokuveliswa kobuninzi, ukwenza kunye nokuvavanya ubungqina be-PCB linyathelo eliphambili lokuqinisekisa ukusebenza kakuhle koyilo.Ngobungqina kunye novavanyo, iingxaki kuyilo zinokufunyanwa kwaye zilungelelaniswe ngexesha, njengokucwangcisa okungekho ngqiqweni kwamanye amacandelo kunye nobubanzi bomgca obanelanga.
五、 Khetha iqabane elifanelekileyo lemveliso
Umgangatho wemveliso eninzi yeebhodi zePCB ixhomekeke kakhulu kwinqanaba lobugcisa kunye nomthamo wemveliso yomenzi.Inkampani yaseShenzhen Fastline PCB ngumenzi wePCB onamava onezixhobo zokuvelisa eziphucukileyo.Xa ukhetha iqabane, ngaphezu kokuqwalasela i-quotation kunye neendleko zokuvelisa, kufuneka uhlawule ingqalelo kwinkqubo yokulawula umgangatho, ixesha lokuhambisa kunye nenkonzo emva kokuthengisa.
六、Ukubekwa esweni komgangatho kunye nophuculo
Kwinkqubo yokuvelisa ubuninzi be-PCB, ukuphunyezwa komgangatho oqhubekayo wokubeka iliso kumlinganiselo obalulekileyo wokuqinisekisa ukuhambelana kwemveliso, kubandakanywa ukubeka iliso ngokungqongqo kwikhonkco ngalinye kumgca wemveliso, njengokuhlolwa kwezinto eziluhlaza, ulawulo lwenkqubo yokuvelisa, uvavanyo lokugqibela lwemveliso, njl. , kunye nenkqubo yokuvelisa Ukuqhuba uhlalutyo lwengcambu yeengxaki ezifunyenwe kwinkqubo kunye nokuphucula inkqubo yokuvelisa ngokufanelekileyo yindlela esebenzayo yokuphucula ngokuqhubekayo umgangatho wemveliso.
Ukwenziwa ngokwezifiso kunye nokuveliswa kobuninzi beebhodi zePCB yinkqubo enzima ebandakanya iingqwalasela ezininzi.Ukusuka ekukhethweni kwezinto eziphathekayo, ukulungiswa koyilo ukuya ekukhethweni kwamaqabane emveliso, ikhonkco ngalinye lifuna ukucwangciswa ngokucophelela kunye nokwenziwa.Ngokusebenzisa izilumkiso ezixoxwe ngokweenkcukacha apha ngasentla, sinethemba lokunceda iinkampani ezifanelekileyo kunye nabayili baphucule ukusebenza kakuhle kwemveliso, ukunciphisa iindleko, kwaye ekugqibeleni bafezekise imveliso ekumgangatho ophezulu.
