Bakeng sa litšebeletso tsa kopano ea PCB e le 'ngoe, likarolo tse ngata li ameha, tse kang tlhahiso ea PCB, theko ea likarolo, kopano ea potoloho e hatisitsoeng, tlhahlobo, joalo-joalo Ka litlhoko tse phahameng tsa bokhoni ba ho etsa lihlahisoa tsa lihlahisoa tsa elektronike, litlhoko tse phahameng tsa tlhahiso ea tlhahiso.Baetsi ba kopano ea elektroniki ba tlameha ho ela hloko ho feta taolo ea boleng ba PCBA.PCBFuture e u tsebisa lintlha tsa bohlokoa tsa taolo ea boleng ba boleng ba elektroniki ba PCBA.
Ntlha ea bohlokoa ea 1: Tlhahiso ea PCB
Ho na le lintlha tse ngata tse khethollang boleng ba PCB, eo har'a eona thepa ea substrate, taolo ea tlhahiso, le botenya ba koporo e leng tsona tse bohlokoa ka ho fetisisa.Ha u khetha fektheri ea PCB, ha ua lokela ho ela hloko theko ea eona feela, empa hape u ele hloko lintlha tsena tsa bohlokoa tsa boleng.Litefiso tsa thepa ea substrate li tloha ho A ho ea ho C, 'me litheko li fapana haholo.Tsamaiso ea boleng bo felletseng le lits'ebeletso tsa botekgeniki tsa litsebi li tla ba le tšusumetso e kholo ho boleng ba PCB.
Ntlha ea bohlokoa 2: Theko ea likarolo
Netefatsa hore likarolo li tsoa ho mofuta oa mantlha, e leng senotlolo sa ts'ebetso ea ho paka, e ka thibelang liphoso tsa batch ho tsoa mohloling.Moetsi oa kopano ea elektronike o hloka ho theha libaka tsa tlhahlobo ea thepa e kenang (IQC, Taolo ea Boleng bo Kenang), hlahloba ho lumellana ha thepa e kenang, 'me u etse mohlala oa ponahalo, litekanyetso tsa likarolo, liphoso, joalo-joalo moetsi oa PCBA o boetse o hloka ho tsoela pele ho ntlafatsa liteishene tsa mofani oa thepa ea eona. .
Ntlha ea bohlokoa ea boraro: ts'ebetso ea holim'a thaba
Ts'ebetsong ea SMT chip processing surface mount process, lik'hamphani tse etsang lisebelisoa tsa elektroniki tsa PCBA li hloka ho netefatsa ho ts'oana le ho ts'oana ha khatiso ea solder paste, mananeo a utloahalang a mechine ea SMT, le ho netefatsa lihlahisoa tse phahameng tsa IC le BGA.Tlhahlobo ea 100% ea AOI le tlhahlobo ea boleng ba boleng (IPQC, Taolo ea Boleng ba Ts'ebetso) e hlokahala haholo.Ka nako e ts'oanang, hoa hlokahala ho matlafatsa tsamaiso ea tlhahlobo ea lihlahisoa tse felileng.
Ntlha ea bohlokoa 4: Tlhahlobo ea PCBA
Baenjiniere ba meralo ka kakaretso ba boloka lintlha tsa tlhahlobo ho PCB mme ba fana ka merero e tsamaellanang ea liteko ho baetsi ba lisebelisoa tsa elektroniki ba PCBA.Litekong tsa ICT le FCT, motlakase oa potoloho le li-curve tsa hajoale lia hlahlojoa, hammoho le liphetho tsa liteko tsa ts'ebetso ea sehlahisoa sa elektroniki (mohlomong ka liforeimi tse ling tsa liteko), ebe meralo ea liteko e bapisoa ho theha nako ea kamohelo, eo le eona e leng bonolo. hore bareki ba tsoelepele ho ntlafatsa.
Ntlha ea bohlokoa ea bohlano: tsamaiso ea batho
Bakeng sa lik'hamphani tsa tlhahiso ea lisebelisoa tsa elektroniki tsa PCBA, lisebelisoa tse tsoetseng pele tse phahameng ke karolo e nyane feela ea eona, 'me ntho ea bohlokoahali ke taolo ea batho.Ntho ea bohlokoa le ho feta ke hore basebeletsi ba tsamaiso ea tlhahiso ba theha mekhoa ea tsamaiso ea tlhahiso ea saense le ho laola ts'ebetsong ea seteishene ka seng.
Tlholisanong e matla ea 'maraka, lik'hamphani tsa tlhahiso ea elektroniki li tsoela pele ho ntlafatsa matla a tsona a kahare le ho ntlafatsa taolo ea bona ea tlhahiso ke senotlolo sa ho ikamahanya le' maraka kamehla.Taolo ea boleng ba tlhahiso le litšebeletso e tla ba mohloli oa tlholisano.
