Monoana oa Khauta

Ho li-memory sticks tsa k'homphieutha le likarete tsa litšoantšo, re ka bona lethathamo la likhokahano tsa khauta, tse bitsoang "menoana ea khauta". Monoana oa Khauta (kapa Edge Connector) indastering ea moralo le tlhahiso ea PCB e sebelisa sehokelo sa sehokelo e le sebaka sa hore boto e hokahane le marang-rang. Ka mor'a moo, a re utloisise mokhoa oa ho sebetsana le menoana ea khauta ho PCB le lintlha tse ling.

Mokhoa oa kalafo oa sefahleho oa monwana oa khauta PCB
1. Electroplating nickel khauta: botenya ho fihlela ho 3-50u ", ka lebaka la conductivity ea eona e phahameng, ho hanyetsa oxidation le ho hanyetsa ho apara, e sebelisoa haholo ho li-PCB tsa menoana ea khauta tse hlokang ho kenngoa le ho tlosoa khafetsa kapa mapolanka a PCB a hlokang ho ferekanngoa khafetsa ha mechine Ka holimo, empa ka lebaka la theko e phahameng ea ho maneha khauta, e sebelisoa feela bakeng sa ho maneha karolo e itseng ea khauta joaloka menoana ea khauta.

2. Khauta e qoelisoang: Botenya bo tloaelehile 1u ", ho fihlela ho 3u" ka lebaka la conductivity ea eona e phahameng, ho bata le ho solderability, e sebelisoa haholo ka mapolanka a PCB a phahameng a nepahetseng a nang le maemo a likonopo, IC e kopantsoeng, BGA, joalo-joalo. ka litlhoko tse tlaase tsa ho hanyetsa li ka boela tsa khetha mokhoa oohle oa ho qoelisoa oa khauta. Litsenyehelo tsa ts'ebetso ea khauta ea qoeliso e tlase haholo ho feta ea ts'ebetso ea elektro-khauta. Mmala oa Immersion Gold o mosehla oa khauta.

Khauta monwana dintlha sebetsa ka PCB
1) E le ho eketsa ho hanyetsa ha menoana ea khauta, hangata menoana ea khauta e lokela ho kenngoa ka khauta e thata.
2) Menoana ea khauta e hloka ho chesoa, hangata 45 °, li-angles tse ling tse kang 20 °, 30 °, joalo-joalo Haeba ho se na chamfer ka moralo, ho na le bothata; 45 ° chamfer ho PCB e bontšitsoe setšoantšong se ka tlase:

3) Monoana oa khauta o hloka ho tšoaroa e le karolo e feletseng ea mask a solder ho bula fensetere, 'me PIN ha e hloke ho bula letlooeng la tšepe;
4) Lesenke la ho qoelisoa le liphaephe tsa ho qoelisa tsa silevera li hloka ho ba bohole bo bonyane ba 14mil ho tloha holimo monoana; ho kgothaletswa hore pad e be hole ho feta 1mm ho tloha monoana nakong ea moralo, ho kenyeletsoa ka liphahlo;
5) U se ke ua ala koporo holim'a monoana oa khauta;
6) Likarolo tsohle tsa lera le ka hare la monoana oa khauta li hloka ho khaola koporo, hangata bophara ba koporo e khaotsoeng ke 3mm e kholoanyane; e ka sebelisoa bakeng sa koporo e sehiloeng ka monoana oa halofo le koporo e sehiloeng ka monoana oohle.

Na “khauta” ea menoana ea khauta ke khauta?

Pele, a re utloisiseng lintlha tse peli: khauta e bonolo le khauta e thata. Khauta e bonolo, hangata khauta e bonolo. Gauta e thata ka kakaretso ke motsoako oa khauta e thata haholoanyane.

Mosebetsi o ka sehloohong oa monoana oa khauta ke ho hokahanya, kahoo o tlameha ho ba le motlakase o motle oa motlakase, ho hanyetsa ho apara, ho hanyetsa oxidation le ho hanyetsa kutu.

Hobane sebopeho sa khauta e hloekileng (khauta) se batla se le bonolo, menoana ea khauta ka kakaretso ha e sebelise khauta, empa ke lesela feela la "khauta e thata (motsoako oa khauta)" e kentsoeng holim'a eona, e ke keng ea fumana conductivity e ntle ea khauta feela, empa. hape e etsa hore e se ke ea hlola e sebetsa ka Abrasion le khanyetso ea oxidation.

Joale na PCB e sebelisitse “khauta e bonolo”? Karabo ke 'nete hore ho na le ts'ebeliso, joalo ka sebaka sa ho ikopanya le likonopo tse ling tsa mohala oa thekeng, COB (Chip On Board) ka terata ea aluminium joalo-joalo. Tšebeliso ea khauta e bonolo ka kakaretso ke ho kenya khauta ea nickel holim'a boto ea potoloho ka electroplating, 'me taolo ea eona ea botenya e fetoha habonolo.
