Ebhodini lokukopisha le-pcb, ukunganaki okuncane kungase kubangele ukuba ipuleti elingezansi liwohloke. Uma ingathuthukisiwe, izothinta ikhwalithi nokusebenza kwebhodi lekhophi ye-pcb. Uma ilahlwa ngokuqondile, izobangela ukulahlekelwa kwezindleko. Nazi ezinye izindlela zokulungisa ukuwohloka kwepuleti eliphansi.
01Ukuhlanganisa
Ukuze uthole ihluzo ezinemigqa elula, ububanzi bemigqa emikhulu kanye nesikhala, kanye nokuguqulwa okungajwayelekile, sika ingxenye ekhubazekile yefilimu engalungile, uphinde uyihlanganise ngokumelene nezindawo zembobo yebhodi lokuhlola lokumba, bese uyikopisha. Kunjalo, lokhu okwemigqa egogekile Lula, ububanzi bomugqa omkhulu kanye nesikhala, ihluzo ezikhubazekile ngendlela engavamile; akufanelekile kumanegethivu anocingo oluningiliziwe nobubanzi bomugqa nesikhala esingaphansi kuka-0.2mm. Lapho uhlanganisa, udinga ukukhokha kancane ngangokunokwenzeka ukuze ulimaze izintambo hhayi ama-pads. Lapho ubuyekeza inguqulo ngemva kokuhlanganisa nokukopisha, naka ukufaneleka kobudlelwano bokuxhumana. Le ndlela ifanele ifilimu engagcwali kakhulu futhi ukuguqulwa kwesendlalelo ngasinye sefilimu akuhambisani, futhi kusebenza ngokukhethekile ekulungiseni ifilimu ye-mask ye-solder kanye nefilimu yongqimba lwamandla webhodi le-multilayer. .
02Ibhodi lokukopisha le-PCB shintsha indlela yesikhundla sembobo
Ngaphansi kwesimo sokuphatha kahle ubuchwepheshe bokusebenza bensimbi yokuhlela yedijithali, qala uqhathanise ifilimu engeyinhle nebhodi lokuhlola ukumba, ulinganise futhi urekhode ubude nobubanzi bebhodi lokuhlola lokumba ngokulandelana, bese kuba sensimbi yokuhlela yedijithali, ngokuvumelana nebhodi lokuhlola lokumba. ubude nobubanzi okubili Usayizi we-deformation, lungisa indawo yembobo, futhi ulungise ibhodi lokuhlola lokumba elilungisiwe ukuze libhekane nenegethivu ekhubazekile. Inzuzo yale ndlela ukuthi iqeda umsebenzi onzima wokuhlela ama-negative, futhi ingaqinisekisa ubuqotho nokunemba kwehluzo. Okubi ukuthi ukulungiswa kwefilimu engalungile ene-deformation yendawo engathi sína kakhulu kanye ne-deformation engalingani akulungile. Ukuze usebenzise le ndlela, kufanele uqale kahle ukusebenza kwethuluzi lokuhlela ledijithali. Ngemuva kokuthi ithuluzi lokuhlela selisetshenziselwa ukunweba noma ukufinyeza indawo yembobo, indawo yembobo engaphandle kokubekezelela kufanele isethwe kabusha ukuze kuqinisekiswe ukunemba. Le ndlela ifanele ukulungiswa kwefilimu ngemigqa eminyene noma i-deformation efanayo yefilimu.
03Indlela yokugqagqana komhlaba
Khulisa izimbobo ebhodini lokuhlola zibe amaphedi ukuze adlulelane futhi ukhubaze ucezu lwesekhethi ukuze uqinisekise ubuncane bezidingo zobuchwepheshe bobubanzi beringi. Ngemuva kwekhophi egqagqene, iphedi i-elliptical, futhi ngemva kokukopisha okweqile, unqenqema lomugqa kanye nediski kuyoba halo futhi ikhubazekile. Uma umsebenzisi enezidingo eziqinile ekubukekeni kwebhodi le-PCB, sicela ulisebenzise ngokuqaphela. Le ndlela ifanele ifilimu enobubanzi bomugqa nesikhala esikhulu kuno-0.30mm futhi imigqa yephethini ayiminyene kakhulu.
04Izithombe
Vele usebenzise ikhamera ukuze wandise noma wehlise ihluzo elonakele. Ngokuvamile, ukulahlekelwa kwefilimu kuphakeme kakhulu, futhi kuyadingeka ukulungisa iphutha izikhathi eziningi ukuze uthole iphethini yesekethe eyanelisayo. Lapho uthatha izithombe, ukugxila kufanele kube okunembile ukuvimbela ukuhlanekezelwa kwemigqa. Le ndlela ifaneleka kuphela ifilimu kasawoti esiliva, futhi ingasetshenziswa uma kungenangqondo ukubhoboza ibhodi lokuhlola futhi isilinganiso sokuguquguquka kubude nobubanzi bezinkomba zefilimu kuyafana.
05Indlela yokulenga
Uma ubheka isenzakalo somzimba ukuthi ifilimu engalungile ishintsha ngokushisa kwemvelo kanye nomswakama, khipha ifilimu engalungile esikhwameni esivaliwe ngaphambi kokuyikopisha, bese uyilenga amahora angu-4-8 ngaphansi kwezimo zendawo yokusebenza, ukuze ifilimu engalungile ibe khona. ikhubazekile ngaphambi kokukopisha. Ngemva kokukopisha, ithuba lokuguqulwa lincane kakhulu.
Kuma-negative asevele akhubazekile, kufanele kuthathwe ezinye izinyathelo. Ngenxa yokuthi ifilimu engalungile izoshintsha ngokushintsha kwezinga lokushisa kwemvelo kanye nomswakama, lapho ilenga ifilimu engalungile, qiniseka ukuthi umswakama nokushisa kwendawo yokomisa nendawo yokusebenza kuyafana, futhi kufanele kube endaweni enomoya futhi emnyama. ukuvimbela ifilimu engalungile ukuthi ingangcoliswa. Le ndlela ifanele ama-negative angaguquki futhi ingavimbela ama-negative ukuthi angawohloki ngemva kokukopishwa.
