Amabhodi esekethe e-PCB asetshenziswa kabanzi emikhiqizweni ehlukahlukene ye-elekthronikhi ezweni lanamuhla elithuthukile ezimbonini.Ngokusho kwezimboni ezahlukene, umbala, umumo, usayizi, ungqimba, kanye nempahla yamabhodi wesifunda se-PCB ahlukile.Ngakho-ke, ulwazi olucacile luyadingeka ekwakhiweni kwamabhodi wesifunda se-PCB, ngaphandle kwalokho ukungaqondi kahle kujwayele ukwenzeka.Lesi sihloko sifingqa amaphutha aphezulu ayishumi ngokusekelwe ezinkingeni zenqubo yokuklama yamabhodi wesifunda se-PCB.
1. Incazelo yezinga lokucubungula ayicacile
Ibhodi elinohlangothi olulodwa liklanywe kungqimba lwe-TOP.Uma ungekho umyalo wokwenza ngaphambili nangemuva, kungase kube nzima ukudayisa ibhodi ngamadivaysi kulo.
2. Ibanga phakathi kwendawo enkulu yefoyili yethusi kanye nohlaka lwangaphandle liseduze kakhulu
Ibanga phakathi kwe-foil yethusi yendawo enkulu kanye nefreyimu yangaphandle kufanele okungenani ibe ngu-0.2mm, ngoba uma ugaya umumo, uma ugaywe ku-foil yethusi, kulula ukubangela ukuba i-foil yethusi iguqe futhi ibangele ukuthi i-solder imelane. ukuwa.
3. Sebenzisa amabhulokhi okugcwalisa ukudweba amaphedi
Amaphedi okudweba anamabhulokhi okugcwalisa angadlula ekuhlolweni kwe-DRC lapho aklama amasekhethi, kodwa hhayi ukucutshungulwa.Ngakho-ke, amaphedi anjalo awakwazi ukukhiqiza ngokuqondile idatha yemaski ye-solder.Lapho i-solder resist isetshenziswa, indawo ye-filler block izohlanganiswa ne-solder resist, okubangela ukuthi idivayisi ye-Welding inzima.
4. Isendlalelo somhlaba kagesi siyiphedi lembali kanye nokuxhumana
Ngenxa yokuthi iklanywe njengomthombo wamandla ngendlela yamaphedi, ungqimba lomhlabathi luphambene nesithombe ebhodini eliphrintiwe langempela, futhi konke ukuxhumeka kuyimigqa engayodwa.Qaphela lapho udweba amasethi amaningana okunikezwa kwamandla kagesi noma izintambo ezimbalwa zokuhlukaniswa komhlaba, futhi ungashiyi izikhala ukuze wenze amaqembu amabili Isekethe emfushane yokuphakelwa kwamandla ayikwazi ukubangela ukuthi indawo yokuxhuma ivinjwe.
5. Abalingiswa abadukile
Amaphedi e-SMD ekhava yezinhlamvu aletha ukuphazamiseka ekuhlolweni okuvaliwe kwebhodi eliphrintiwe kanye nengxenye yokushisela.Uma ukwakheka komlingiswa kukuncane kakhulu, kuzokwenza ukuphrinta kwesikrini kube nzima, futhi uma kukhulu kakhulu, izinhlamvu zizodlulana, okwenza kube nzima ukuhlukanisa.
6.amaphedi edivayisi yokukhweza angaphezulu mafushane kakhulu
Lokhu okokuhlola ukungasebenzi.Kumathuluzi okukhweza aminyene kakhulu, ibanga phakathi kwamaphini amabili lincane kakhulu, namaphedi nawo mancane kakhulu.Lapho ufaka izikhonkwane zokuhlola, kufanele zinyakaziswe phezulu naphansi.Uma i-pad design imfushane kakhulu, nakuba ingekho Izothinta ukufakwa kwedivayisi, kodwa izokwenza izikhonkwane zokuhlola zingahlukaniseki.
7. Isilungiselelo sokuvula iphedi elinohlangothi olulodwa
Amaphedi anohlangothi olulodwa ngokuvamile awabhojwa.Uma izimbobo ezibhoboziwe zidinga ukumakwa, indawo yokuvula kufanele yakhelwe njengoziro.Uma inani lenzelwe, khona-ke lapho idatha yokumba ikhiqizwa, izixhumanisi zembobo zizovela kulesi sikhundla, futhi kuzovela izinkinga.Amaphedi anohlangothi olulodwa afana nezimbobo ezibhoboziwe kufanele amakwe ngokukhethekile.
8. Ukugqagqana kwephedi
Phakathi nenqubo yokumba, i-drill bit izophulwa ngenxa yokubhoboza okuningi endaweni eyodwa, okuholela ekulimaleni kwembobo.Izimbobo ezimbili ebhodini lezingqimba eziningi ziyagqagqana, futhi ngemva kokudwetshwa kwe-negetive, izovela njengepuleti lokuhlukanisa, okuholela ekulahlekeni.
9. Kunamabhulokhi amaningi okugcwalisa ekwakhiweni noma amabhulokhi okugcwalisa agcwele imigqa emincane kakhulu
Idatha ye-photoplotting ilahlekile, futhi idatha ye-photoplotting ayiphelele.Ngoba ibhulokhi yokugcwalisa idonswa ngamunye ngamunye ekucubunguleni idatha yokudweba ukukhanya, ngakho inani ledatha yokudweba ukukhanya elikhiqiziwe likhulu kakhulu, okwandisa ubunzima bokucubungula idatha.
10. Ukuhlukunyezwa kongqimba lwezithombe
Okunye ukuxhumeka okungenamsebenzi kwenziwe kwezinye izendlalelo zezithombe.Ekuqaleni bekuyibhodi elinezingqimba ezine kodwa kwaklanywa izingqimba ezingaphezu kwezinhlanu zamasekethe, okwadala ukungezwani.Ukwephulwa komklamo ovamile.Ungqimba lwezithombe kufanele lugcinwe luqinile futhi lucacile lapho uklama.
