Kunezinhlobo eziningi zamabhodi wesifunda emakethe, futhi amagama ochwepheshe ahlukile, phakathi kwawo ibhodi le-fpc lisetshenziswa kakhulu, kodwa abantu abaningi abazi okuningi ngebhodi le-fpc, ngakho-ke ibhodi le-fpc lisho ukuthini?

I-1, ibhodi le-fpc libizwa nangokuthi "ibhodi lesifunda eliguquguqukayo", ingenye yebhodi lesifunda eliphrintiwe le-PCB, iwuhlobo lokusetshenziswa kwezinto zokuvikela njenge-substrate, njengokuthi: ifilimu ye-polyimide noma i-polyester, bese ngenqubo ekhethekile eyenziwe. webhodi lesifunda eliphrintiwe. Ukuminyana kwezintambo zaleli bhodi lesifunda ngokuvamile kuphakeme ngokuqhathaniswa, kodwa isisindo sizoba lula uma kuqhathaniswa, ukushuba kuzoba mncane kakhulu, futhi kunokusebenza okuhle kokuguquguquka, kanye nokusebenza kahle kokugoba.

2, fpc board kanye PCB board umehluko omkhulu. I-substrate yebhodi le-fpc ngokuvamile i-PI, ngakho-ke ingagotshwa ngokungenasizathu, igobe, njll., kuyilapho i-substrate yebhodi le-PCB ngokuvamile i-FR4, ngakho ayikwazi ukugoba noma ukugoba. Ngakho-ke, ukusetshenziswa nezinkambu zokusetshenziswa kwebhodi le-fpc nebhodi le-PCB nazo zihluke kakhulu.

I-3, ngoba ibhodi le-fpc lingagoba futhi liguquguquke, ibhodi le-fpc lisetshenziswa kabanzi endaweni edinga ukuguquguquka ngokuphindaphindiwe noma ukuxhumana phakathi kwezingxenye ezincane. Ibhodi le-PCB liqinile, ngakho lisetshenziswa kakhulu kwezinye izindawo lapho lingadingi ukugotshwa futhi amandla anzima kakhulu.

I-4, ibhodi ye-fpc inezinzuzo zobukhulu obuncane, isisindo esincane, ngakho-ke inganciphisa ngempumelelo usayizi wemikhiqizo ye-elekthronikhi incane kakhulu, ngakho-ke isetshenziswa kabanzi embonini yomakhalekhukhwini, imboni yekhompyutha, imboni ye-TV, imboni yekhamera yedijithali nezinye. imboni yemikhiqizo ye-elekthronikhi encane uma kuqhathaniswa.

I-5, ibhodi le-fpc alikwazi ukugoba ngokukhululekile kuphela, kodwa futhi lingalimaza ngokungafanele noma ligoqwe ndawonye, ​​​​futhi lingahlelwa ngokukhululekile ngokuvumelana nezidingo zesakhiwo sesikhala. Esikhaleni se-three-dimensional, ibhodi le-fpc lingaphinde lihanjiswe ngokungafanele noma lifakwe nge-telescoped, ukuze inhloso yokuhlanganisa ingafinyelelwa phakathi kocingo nomhlangano wengxenye.

Ayini amafilimu omile e-PCB?

1, i-PCB yohlangothi olulodwa

I-base plate yenziwe ngephepha le-phenol copper laminated board (iphepha le-phenol njengesisekelo, elimbozwe nge-foil yethusi) kanye nebhodi le-Epoxy copper laminated board. Iningi lazo lisetshenziswa emikhiqizweni kagesi yasekhaya njengemisakazo, izinto zikagesi ze-AV, izifudumezi, iziqandisi, imishini yokuwasha, nemishini yokuthengisa efana namaphrinta, imishini yokuthengisa, imishini yesekethe, nezingxenye ze-elekthronikhi.

2, i-PCB enamacala amabili

Izinto eziyisisekelo yibhodi le-Glass-Epoxy copper laminated board, i-GlassComposite copper laminated board, kanye nebhodi le-Epoxy copper laminated board. Iningi lazo lisetshenziswa kumakhompuyutha omuntu siqu, i-electronic Musical Instruments, izingcingo ezinemisebenzi eminingi, imishini ye-automotive electronic, ama-peripheral electronic, amathoyizi kagesi, njll. Ngokuqondene ne-Glass benzene resin copper laminated laminates, i-Glass polymer copper laminated laminates isetshenziswa kakhulu emishinini yokuxhumana. , imishini yokusakaza ngesathelayithi, nemishini yokuxhumana ephathwayo ngenxa yezici zayo ezinhle kakhulu ze-high-frequency, futhi-ke, izindleko nazo ziphezulu.

3, 3-4 izendlalelo ze-PCB

Izinto eziyisisekelo ngokuyinhloko ziyi-Glass-Epoxy noma i-benzene resin. Isetshenziswa kakhulu kumakhompiyutha omuntu, Mina (i-electronics yezokwelapha, i-medical electronics) imishini, imishini yokulinganisa, imishini yokuhlola i-semiconductor, imishini ye-NC (NumericControl, nokulawula izinombolo), ukushintshwa kwe-electronics, imishini yokuxhumana, amabhodi wesekhethi yememori, amakhadi e-IC, njll., kukhona futhi ingilazi yokwenziwa yethusi laminated ibhodi njengoba multi-ungqimba PCB materials, Ikakhulukazi gxila ezinhle kakhulu processing izici zayo.

4,6-8 izingqimba PCB

Izinto eziyisisekelo zisasekelwe ku-GLASS-epoxy noma i-Glass benzene resin. Isetshenziswa ekushintsheni kwe-elekthronikhi, imishini yokuhlola i-semiconductor, amakhompyutha womuntu anosayizi omaphakathi, i-EWS (EngineeringWorkStation), i-NC neminye imishini.

5, izingqimba ezingaphezu kuka-10 ze-PCB

I-substrate yenziwe kakhulu nge-Glass benzene resin, noma i-GLASS-epoxy njenge-multi-layer PCB substrate material. Ukusetshenziswa kwalolu hlobo lwe-PCB kukhethekile kakhulu, iningi lawo amakhompyutha amakhulu, amakhompyutha anesivinini esikhulu, imishini yokuxhumana, njll., ikakhulukazi ngoba inezici zemvamisa ephezulu kanye nezici ezinhle kakhulu zokushisa okuphezulu.

6, enye into engaphansi kwe-PCB

Ezinye izinto ze-PCB substrate ziyi-aluminium substrate, i-iron substrate nokunye. Isifunda sakhiwe ku-substrate, iningi lazo elisetshenziswa ekuguquleni (imoto encane) imoto. Ngaphezu kwalokho, kukhona PCB nezimo (FlexiblPrintCircuitBoard), isifunda kwakhiwa phezu polymer, i-polyester nezinye izinto eziyinhloko, ingasetshenziswa njengendlela ungqimba olulodwa, ungqimba double, ukuze multi-ungqimba ibhodi kungaba. Leli bhodi lesifunda eliguquguqukayo lisetshenziswa ikakhulukazi ezingxenyeni ezinyakazayo zamakhamera, imishini ye-OA, njll., kanye nokuxhumana phakathi kwe-PCB eqinile noma inhlanganisela yokuxhumana ephumelelayo phakathi kwe-PCB eqinile ne-PCB ethambile, mayelana nendlela yokuhlanganisa yokuxhuma ngenxa yokuphakama okuphezulu. nokunwebeka, ukuma kwayo kuhlukene.

Ibhodi elinezingqimba eziningi kanye nepuleti le-TG eliphakathi nendawo neliphezulu

Okokuqala, amabhodi wesekethe we-PCB anezingqimba eziningi ngokuvamile asetshenziswa kuziphi izindawo?

Amabhodi wesekethe we-Multilayer PCB avame ukusetshenziswa emishinini yokuxhumana, okokusebenza kwezokwelapha, ekulawuleni izimboni, ezokuphepha, ezobuchwepheshe bezimoto, ezondiza, nezinkambu zamakhompiyutha; Njengoba “amandla amakhulu” kule mikhakha, ngokwanda okuqhubekayo kwemisebenzi yomkhiqizo, imigqa eminyene ngokwandayo, izidingo zemakethe ezihambisanayo zekhwalithi yebhodi nazo ziya ngokuya zikhuphuka, kanye nesidingo samakhasimende esiphakathi nendawo nesiphezulu. Amabhodi wesifunda we-TG akhula njalo.

Okwesibili, ukubaluleka kwamabhodi wesekethe we-PCB anezingqimba eziningi

Ibhodi le-PCB elivamile lizoba nokuguquguquka nezinye izinkinga emazingeni okushisa aphezulu, kuyilapho izici zemishini nezikagesi nazo zingase zehle kakhulu, zinciphise impilo yesevisi yomkhiqizo. Insimu yokusetshenziswa kwebhodi le-PCB enezingqimba eziningi ngokuvamile itholakala embonini yezobuchwepheshe ephezulu, edinga ngokuqondile ukuthi ibhodi libe nokuzinza okuphezulu, ukumelana namakhemikhali aphezulu, futhi lingakwazi ukumelana nokushisa okuphezulu, umswakama ophezulu nokunye.

Ngakho-ke, ukukhiqizwa kwamabhodi we-PCB anezingqimba eziningi kusebenzisa okungenani amapuleti e-TG150, ukuze kuqinisekiswe ukuthi ibhodi lesifunda lincishiswa yizici zangaphandle ekusetshenzisweni kwesicelo futhi linweba impilo yesevisi yomkhiqizo.

Okwesithathu, ukuqina kohlobo lwepuleti le-TG eliphezulu nokuthembeka okuphezulu

Liyini inani le-TG?

Inani le-TG: I-TG izinga lokushisa eliphakeme kakhulu lapho ishidi lihlala liqinile, futhi inani le-TG libhekisela ekushiseni lapho i-polymer e-amorphous (okuhlanganisa nengxenye ye-amorphous ye-crystalline polymer) ishintsha isuka esimweni esiyingilazi iye esimweni sokunwebeka esiphezulu (irabha. izwe).

Inani le-TG izinga lokushisa elibalulekile lapho i-substrate encibilika khona ukusuka kokuqinile kuye koketshezi lwerabha.

Izinga levelu ye-TG lihlobene ngokuqondile nokuzinza nokuthembeka kwemikhiqizo ye-PCB, futhi uma liphakeme inani le-TG lebhodi, kuqina ukuzinza nokuthembeka.

Ishidi le-TG eliphakeme linezinzuzo ezilandelayo:

I-1) Ukumelana nokushisa okuphezulu, okunganciphisa ukuntanta kwamaphedi e-PCB ngesikhathi sokuncibilika okushisayo kwe-infrared, i-welding kanye nokushaqeka okushisayo.

I-2) I-coefficient ephansi yokwandisa okushisayo (i-CTE ephansi) inganciphisa ukungqubuzana okubangelwa izici zokushisa, futhi inciphise ukuphuka kwethusi ekhoneni lomgodi okubangelwa ukwanda okushisayo, ikakhulukazi kumabhodi e-PCB anezendlalelo eziyisishiyagalombili noma ngaphezulu, ukusebenza kwe-plated ngokusebenzisa izimbobo. ingcono kunaleyo yamabhodi e-PCB anamanani ajwayelekile e-TG.

I-3) Inokumelana okuhle kakhulu kwamakhemikhali, ukuze ibhodi le-PCB lifakwe enqubweni yokwelapha emanzi kanye nezixazululo eziningi zamakhemikhali, ukusebenza kwayo kusenjalo.
