Yila ibhodi yesekethe yePCB epheleleyo, efuna iinkqubo ezininzi ezidinayo nezinzima. Ngokubanzi, ikakhulu ibandakanya ukucacisa iimfuno zemveliso, uyilo lwenkqubo yehardware, ukhetho lwesixhobo, umzobo wePCB, ukungqina imveliso yePCB, ukulungisa i-welding kunye namanye amanyathelo.
Ngokubanzi, abaqulunqi banoluhlu lwabo lokukhangela umgangatho woyilo, ezinye zazo zivela kwinkampani okanye kwisebe. Elinye icandelo livela kwiinkcukacha zoyilo kwaye elinye inxalenye livela kwisishwankathelo samava ethu. Uhlolo olukhethekileyo lubandakanya ukuhlolwa kwe-DRC kunye nokuhlolwa kwe-DFM yoyilo. Ezi nxalenye zimbini zijolise kwimveliso yoyilo lwePCB kunye neefayile ze-photolithography zangasemva.
Abaqalayo ukuyila i-PCB, bahlala bedibana neengxaki eziqhelekileyo zomgangatho ophantsi ngenxa yokunqongophala kwamava kunye noyilo olungachanekanga. Imveliso eyiliweyo ayinakuphumelela ngexesha elinye, inokuthatha uhlaziyo oluninzi ukuze iphumelele, kwaye kunokubakho okushiyiweyo ngexesha lenkqubo yohlaziyo. Ezinye iingxaki eziqhelekileyo , umzekelo : Umgca owaphukileyo.
Yintoni umgca owaphukileyo? Njengoko igama libonisa, ngumgca ongenasiqalo okanye isiphelo, okanye umgca oyekisiweyo kuthungelwano .
Oku kulandelayo kuya kuchaza indlela i-software ye-Huaqiu DFM enokukhangela ngayo imigca ephukileyo yeefayile ezipeyintiweyo zeefoto ukuphepha uluhlu lweengxaki ezibangelwa yimigca ephukileyo. imiba yomgangatho wemveliso.
Uvela njani umgca ophukileyo?
1. I-fan-out hole yomzila ide kakhulu, ibangele iingcingo eziphukileyo: Emva kokuguqula ifayile yokuyila, ngaphandle kokusebenzisa i-DFM iitshekhi, i-cloth ye-routing Akukho kubhobhoza umngxuma ixesha elide, kwaye ayixhunyiwe kuyo nayiphi na indawo, okubangelwa iingcingo eziphukileyo. Ukuba i-DFM isetyenziselwa ukujonga lo mgca Wophukileyo Enyanisweni, lo mgca wophukileyo unokucinywa kwaye urhoxiswe.
2. Iziphelo eziphukileyo zocingo lobhedu: Akukho ukulungiswa kobhedu okwenziwa emva kokuba uyilo lugqityiwe, ukususa ubhedu obuseleyo, okubangele iingcingo eziphukileyo. Uyilo olugqityiweyo Sebenzisa ukukhangela kwe-DFM emva kokugqitywa ukuphepha lo mgca ophukileyo , isofthiwe ibona olu hlobo locingo oluphukileyo , unokubeka olu hlobo lomgca ophukileyo Cima ukuqhutyelwa phambili.
3. Iingcingo ezaphukileyo kuthungelwano oluvulekileyo: Olu hlobo lwengxaki lubangelwa ngokuqinisekileyo kukungenzi isheke ye-DRC, kwaye ungasebenzisi i-DFM yokukhangela emva kokuzoba ukukhanya. Ukuvela kweengxaki ezinjalo akuyona nje ingxaki yokwenziwa kwezinto ezibangelwa iingcingo eziphukileyo, kodwa ngokugqithiseleyo, iisekethe ezivulekileyo, ezikhokelela ekungaphumeleli kwebhetshi yonke yeemveliso. Ayifumaneki.
Zeziphi iingxaki eziziswa ngocingo olwaphukileyo kwimveliso?
4. Isekethe evulekileyo: Ibhodi eveliswa ngokuvelisa ifilimu engalunganga, indawo ehlanganiswe yifilimu eyomileyo yisekethe, kwaye i-foil yobhedu ngaphandle kwefilimu eyomileyo ifakwe I-substrate. Xa kukho umgca ophukileyo kwifayile yesekethe, umgca ophukileyo awugqunywanga yifilimu eyomileyo emva kwe-lamination, i-exposure and development, kunye ne-etching iya ku-Etch off ubhedu kwindawo yocingo oluphukileyo, okubangela isiphaluka esivulekileyo.
2. Isiphaluka esifutshane: Emva kwe-etching, ukuba kukho ucingo olude oluphukileyo, xa udlula kumatshini wokugaya , ngenxa yokuba umgca ophukileyo awukho uxhulumaniso kunye nezinye Iingcingo eziphukileyo zixhunyiwe kwindawo efanayo, ngoko akukho ukunamathela kwaye kulula ukuwa. Xa ukugaya ipleyiti, iingcingo ezaphukileyo ziya kuwa kwezinye iingcingo, ebangela ezinye iingcingo kwiLocal network yesekethe emfutshane.
3. Ukulibaziseka komjikelezo wokuvelisa: Ngethuba lenkqubo yokuvelisa, injineli ye-CAM yefektri yebhodi yafumanisa ukuba umgca ophukileyo kufuneka uqinisekiswe kunye nonjiniyela woyilo. Ngaba kufuneka uqhagamshele kwezinye iindawo? Ngenxa yokuba injineli ye-CAM yefektri yebhodi isebenza kuphela imidwebo yeefayile zefotolithography kwaye ayiyi kudibanisa inethiwekhi eyilwe ngokuthanda. Ukuba kukho nakuphi na ukungaqhelekanga kwifayile yoyilo, nxibelelana kwakhona. , kuthatha ixesha , ukuba imveliso yokuhanjiswa ngokukhawuleza, Ngokuqinisekileyo iya kulibazisa ukuhanjiswa kwemveliso , kwaye unxibelelwano lunazo iindleko.
