Ts'ebetso ea Kopano ea SMT
1. Sebaka (pheko)
Mosebetsi oa eona ke ho qhibilihisa sekhomaretsi sa patch e le hore likarolo tsa holim'a thaba le boto ea PCB li hokahane ka thata.
Thepa e sebelisoang ke onto e phekolang, e ka morao ho mochini o behang moleng oa SMT.
2. Re-soldering
Karolo ea eona ke ho qhibilihisa peista ea solder, e le hore likarolo tsa holim'a thaba le boto ea PCB li hokahane ka thata.Thepa e neng e sebelisoa e ne e le onto ea reflow, e ka mor'a liphahlo.
Mounter moleng oa tlhahiso ea SMT.
3. Ho hloekisa kopano ea SMT
Seo e se etsang ke ho tlosa masala a solder joalo ka ux
PCB e kopaneng e kotsi 'meleng oa motho.Thepa e sebelisoang ke mochine oa ho hlatsoa, sebaka se ka ba
Ha e lokisoe, e ka ba inthaneteng kapa ntle le inthanete.
4. Tlhahlobo ea kopano ea SMT
Mosebetsi oa eona ke ho hlahloba boleng ba welding le boleng ba kopano
Boto ea PCB e kopaneng.
Thepa e sebelisoang e kenyelletsa likhalase tse holisang, microscope, tester in-circuit (ICT), tlhahlobo ea nale, tlhahlobo ea othomathike ea optical (AOI), sistimi ea tlhahlobo ea X-RAY, tester e sebetsang, jj.
5. Ho tsosolosa kopano ea SMT
Mosebetsi oa eona ke ho tsosolosa boto ea PCB e hlōlehileng
Phoso.Lisebelisoa tse sebelisoang ke tšepe ea soldering, seteishene sa ho tsosolosa, joalo-joalo.
kae kapa kae moleng oa tlhahiso.Joalo ka ha u tseba, ho na le litaba tse nyane nakong ea tlhahiso, kahoo kopano ea ho lokisa matsoho ke eona tsela e molemohali.
6. Sephutheloana sa kopano ea SMT
PCBMy e fana ka kopano, ho paka ka tloaelo, ho ngola, ho hlahisa liphaposi tse hloekileng, taolo ea ho thibela likokoana-hloko le litharollo tse ling ho fana ka tharollo e felletseng ea litlhoko tsa k'hamphani ea hau.
Ka ho sebelisa othomathike ho bokella, ho paka le ho netefatsa lihlahisoa tsa rona, re ka fa bareki ba rona ts'ebetso e tšepahalang le e sebetsang ea tlhahiso.
Ka boiphihlelo ba lilemo tse fetang 10 re le mofani oa litšebeletso tsa tlhahiso ea elektroniki bakeng sa Khokahano ea Mehala, rona ANKE re ts'ehetsa lisebelisoa tse fapaneng le liprothokholo tsa likhokahano:
> Lisebelisoa le lisebelisoa tsa khomphutha
> Liseva le lirutha
> RF & Microwave
> Litsi tsa data
> Polokelo ya data
> Lisebelisoa tsa Fiber optic
> Li-transceivers le li-transmitters
Phapang lipakeng tsa FFC le FPC Line
Botenya ba thapo ea FFC ke 0.12mm.FFC thapo ka filimi e ka holimo le ka tlaase insulating, mahareng laminated bataletseng koporo conductors, kahoo kabel botenya ka filimi botenya + IT = + mokhanni botenya ka filimi botenya.Hangata e sebelisoa filimi botenya: 0.043mm, 0.060,0.100, ka tloaelo ho sebelisoa conductor botenya: 0.035,0.05,0.100mm joalo;
Ea bobeli, litheko li fapane ka lebaka la mekhoa e fapaneng ea tlhahiso.
Mekhoa e fapaneng ea tlhahiso e fella ka litšenyehelo tse fapaneng.Tse kang boto e entsoeng ka khauta le boto e entsoeng ka thini, sebōpeho sa ho tsamaisa le ho phunya, tšebeliso ea mela ea skrine ea silika le mela e omeletseng ea lifilimi e tla theha litšenyehelo tse fapaneng, tse hlahisang phapang ea theko.
2. Mohala oa FPC ke potoloho e hatisitsoeng e feto-fetohang.Ho ea ka pono ea tlhahiso, mekhoa ea ho theha potoloho ea mohala oa FPC le mohala oa FFC li fapane:
(1) FPC ke ho sebetsana le FCCL (flexible copper clad foil) ka lik'hemik'hale ho fumana liboto tsa potoloho tse feto-fetohang tse nang le mekhoa e fapaneng ea potoloho;
(2) Thapo ea FFC e sebelisa sekontiri sa terata ea koporo e bataletseng e pakeng tsa likarolo tse ka holimo le tse ka tlaase tsa lifilimi tsa foil tse sireletsang.
3, lintlha tsa mantlha tsa thapo tsa FFC le likarolo tse ikhethang:
Bophelo ba cable ea FFC hangata ke linako tse 5000-8000 tsa ho bula le ho koala, haeba karolelano ea ho bula le ho koala makhetlo a 10 ka letsatsi, bophelo bohle ba ho sebetsa e tla ba selemo le halofo kapa ho feta.
Litlhaloso tsa bohlokoa / Likarolo tse khethehileng:
Mocheso o sebetsang: 80C 105C.
Matla a lekantsoeng: 300V, sena se loketse lisebelisoa tsa elektroniki tse akaretsang, likhokahano tsa kahare tsa lisebelisoa tsa motlakase, joalo ka lisebelisoa tsa audio-visual, jj.
Mokhanni: 32-16AWG (0.03-1.31mm2), e kentsoeng kapa e se nang letho ea koporo.
