Kukho iintlobo ezininzi zeebhodi zeesekethe kwimarike, kwaye imimiselo yobuchwephesha yahlukile, phakathi kwayo ibhodi ye-fpc isetyenziswa kakhulu, kodwa abantu abaninzi abazi kakhulu malunga nebhodi ye-fpc, ngoko ibhodi ye-fpc ithetha ntoni?
I-1, ibhodi ye-fpc ikwabizwa ngokuba "yibhodi yesekethe eguquguqukayo", yenye yebhodi yesekethe eprintwayo yePCB, luhlobo lokusetyenziswa kwezinto ezigqumayo njenge substrate, njenge: polyimide okanye ifilimu yepolyester, kwaye emva koko ngenkqubo ekhethekileyo eyenziweyo. yebhodi yesekethe eprintiweyo. Ukuxinana kweengcingo zale bhodi yesekethe ngokuqhelekileyo kuphezulu, kodwa ubunzima buya kuba lula, ubukhulu buya kuba buncinci, kwaye bube nokusebenza kakuhle kokuguquguquka, kunye nokusebenza kakuhle kokugoba.
I-2, ibhodi ye-fpc kunye nebhodi ye-PCB ngumahluko omkhulu. I-substrate yebhodi ye-fpc ngokubanzi i-PI, ngoko inokugoba ngokungenasizathu, iguquguquke, njl., ngelixa i-substrate yebhodi ye-PCB ngokuqhelekileyo i-FR4, ngoko ayikwazi ukugoba ngokungqongqo kwaye iguqulwe. Ngoko ke, ukusetyenziswa kunye neendawo zokusetyenziswa kwebhodi ye-fpc kunye nebhodi ye-PCB nazo zahluke kakhulu.
I-3, ngenxa yokuba ibhodi ye-fpc inokugoba kwaye iguquguquke, ibhodi ye-fpc isetyenziswe ngokubanzi kwindawo efuna ukuguqulwa ngokuphindaphindiweyo okanye ukudibanisa phakathi kwamacandelo amancinci. Ibhodi ye-PCB ilukhuni ngokwentelekiso, ngoko isetyenziswa ngokubanzi kwezinye iindawo apho kungafuneki ukuba igobe kwaye amandla anzima.
I-4, ibhodi ye-fpc ineenzuzo zobukhulu obuncinci, ubunzima obulula, ngoko inokunciphisa ngokufanelekileyo ubungakanani beemveliso zombane zincinci kakhulu, ngoko isetyenziswa ngokubanzi kushishino lwefowuni ephathwayo, ishishini lekhompyutha, ishishini leTV, ishishini lekhamera yedijithali kunye nezinye. incinci ngokwentelekiso, kushishino lweemveliso zombane eziphucukileyo ngokwentelekiso.
I-5, ibhodi ye-fpc ayinakugoba ngokukhululekileyo kuphela, kodwa inokuba nenxeba ngokungenasizathu okanye ihlanganiswe kunye, kwaye inokulungiswa ngokukhululekileyo ngokweemfuno zesakhiwo sendawo. Kwisithuba esine-dimensional emithathu, ibhodi ye-fpc nayo inokushukunyiswa ngokungekho mthethweni okanye i-telescoped, ukwenzela ukuba injongo yokudibanisa inokufezekiswa phakathi kocingo kunye nendibano yecandelo.
Ziziphi iifilimu ezomileyo zePCB?
1, iPCB enecala elinye
Isiseko seplate yenziwe ngephepha phenol copper laminated board (iphenol yephepha njengesiseko, ifakwe ngefoyile yobhedu) kunye nephepha le-Epoxy copper laminated board. Uninzi lwazo lusetyenziswa kwiimveliso zombane zasekhaya ezinje ngerediyo, izixhobo zombane ze-AV, izifudumezi, iifriji, oomatshini bokuhlamba, kunye noomatshini borhwebo abanje ngabashicileli, oomatshini bokuthengisa, oomatshini beesekethe, kunye nezinto zombane.
2, iPCB enamacala amabini
Izinto ezisisiseko ziyi-Glass-Epoxy copper laminated board, i-GlassComposite copper laminated board, kunye ne-paper Epoxy copper laminated board. Uninzi lwazo lusetyenziswa kwiikhompyuter zobuqu, izixhobo zoMculo ze-elektroniki, iifowuni ezisebenza ngeendlela ezininzi, oomatshini be-elektroniki bezemoto, iiperipherals zombane, iithoyi zombane, njl. , oomatshini bokusasaza ngesathelayithi, kunye noomatshini bonxibelelwano oluphathwayo ngenxa yeempawu zabo ezibalaseleyo zokuphindaphinda, kwaye ke, iindleko nazo ziphezulu.
3, 3-4 umaleko PCB
Izinto ezisisiseko ziyi-Glass-Epoxy okanye i-benzene resin. Ikakhulu isetyenziswa kwiikhompyuter zobuqu, oomatshini beMe (i-elektroniki zonyango, i-elektroniki yezonyango), oomatshini bokulinganisa, oomatshini bokuvavanya i-semiconductor, oomatshini beNC (Ulawulo lwamanani, ulawulo lwamanani), oomatshini bombane, oomatshini bonxibelelwano, iibhodi zeesekethe zememori, amakhadi e-IC, njl., kukho kwakhona iglasi eyenziwe ngobhedu ibhodi elaminethiweyo njengoko multi- umaleko PCB izixhobo, Ikakhulu kugxininise iimpawu zayo ezibalaseleyo processing.
4,6-8 umaleko PCB
Izinto ezisisiseko zisasekelwe kwi-GLASS-epoxy okanye kwi-Glass benzene resin. Isetyenziselwa ukutshintshwa kombane, oomatshini bokuvavanya i-semiconductor, iikhomputha zomntu ophakathi, i-EWS (i-EngineeringWorkStation), i-NC kunye nabanye oomatshini.
5, ngaphezu kwe-10 umaleko we-PCB
Isubstrate yenziwe ikakhulu ngeGlasi benzene resin, okanye iGLASS-epoxy njengesixhobo esinemigangatho emininzi sePCB substrate. Ukusetyenziswa kolu hlobo lwePCB kukhethekileyo, uninzi lwazo ziikhompyuter ezinkulu, iikhompyuter ezinesantya esiphezulu, oomatshini bonxibelelwano, njl.
6, ezinye PCB substrate imathiriyeli
Ezinye izinto ze-PCB substrate ziyi-aluminium substrate, i-iron substrate njalo njalo. Isekethe yenziwe kwi-substrate, ininzi yayo isetyenziswe kwi-turnaround (imoto encinci) imoto. Ukongeza, kukho i-PCB eguquguqukayo (i-FlexiblPrintCircuitBoard), isiphaluka senziwa kwi-polymer, i-polyester kunye nezinye izinto eziphambili, zingasetyenziswa njengomaleko omnye, i-double layer, kwi-multi-layer board ingaba. Le bhodi yesekethe bhetyebhetye isetyenziswa ikakhulu kwiindawo ezishukumayo iikhamera, oomatshini OA, njl, kunye noqhagamshelo phakathi PCB enzima okanye udibaniso olusebenzayo uxhulumaniso phakathi PCB enzima kunye PCB ethambileyo, njengoko udibaniso indlela yodibaniso ngenxa eliphezulu. u-elasticity, ukumila kwayo kuhlukeneyo.
Ibhodi ye-Multi-layer kunye nepleyiti ye-TG ephakathi kunye nephezulu
Okokuqala, iibhodi zesekethe ze-PCB ezinamanqwanqwa amaninzi zisetyenziswa ngokubanzi kweziphi iindawo?
Iibhodi zesekethe ze-Multilayer PCB zisetyenziswa ngokubanzi kwizixhobo zonxibelelwano, izixhobo zonyango, ulawulo lwemizi-mveliso, ukhuseleko, i-automotive electronics, aviation, computer peripheral fields; Njengoko "amandla angundoqo angundoqo" kule mimandla, kunye nokwanda okuqhubekayo kwemisebenzi yemveliso, imigca exineneyo ngakumbi nangakumbi, iimfuno zemarike ezihambelanayo zomgangatho webhodi nazo ziya ziphezulu nangaphezulu, kunye nemfuno yomthengi phakathi kunye nephezulu. Iibhodi zeesekethe ze-TG zihlala zisanda.
Okwesibini, ubuchule beebhodi zeesekethe ze-PCB ezininzi
Ibhodi ye-PCB eqhelekileyo iya kuba ne-deformation kunye nezinye iingxaki kumaqondo obushushu aphezulu, ngelixa iimpawu zoomatshini kunye nombane zinokuhla ngokukhawuleza, ukunciphisa ubomi benkonzo yemveliso. Intsimi yokusetyenziswa kwebhodi ye-PCB ye-multi-layer ifumaneka ngokubanzi kwi-teknoloji ephezulu, efuna ngokuthe ngqo ukuba ibhodi ibe nozinzo oluphezulu, ukumelana neekhemikhali eziphezulu, kwaye inokumelana nokushisa okuphezulu, ukufuma okuphezulu njalo njalo.
Ngoko ke, ukuveliswa kweebhodi ze-PCB ezininzi zisebenzisa iipleyiti ze-TG150 ubuncinane, ukwenzela ukuba kuqinisekiswe ukuba ibhodi yesekethe iyancitshiswa yimiba yangaphandle kwinkqubo yesicelo kwaye yandisa ubomi benkonzo yemveliso.
Okwesithathu, ukuzinza kohlobo lweplate ye-TG ephezulu kunye nokuthembeka okuphezulu
Yintoni ixabiso le-TG?
TG ixabiso: TG lelona qondo lobushushu liphezulu apho iphepha lihlala liqinile, kwaye ixabiso le-TG libhekiselele kwiqondo lobushushu apho i-polymer e-amorphous (ikwabandakanya inxalenye ye-amorphous ye-crystalline polymer) iinguqu ukusuka kwimo yeglasi ukuya kwimo ye-elastic ephezulu (irabha ilizwe).
Ixabiso le-TG liqondo lobushushu elibalulekileyo apho i-substrate inyibilika ukusuka kokuqinileyo ukuya kulwelo lwerabha.
Inqanaba lexabiso le-TG lihambelana ngokuthe ngqo nokuzinza kunye nokuthembeka kweemveliso ze-PCB, kunye nexabiso eliphezulu le-TG yebhodi, ukuqina kozinzo kunye nokuthembeka.
Iphepha le-TG eliphezulu lineenzuzo ezilandelayo:
I-1) Ukumelana nobushushu obuphezulu, obunokunciphisa ukudada kweepads ze-PCB ngexesha lokunyibilika kwe-infrared, i-welding kunye ne-thermal shock.
I-2) I-coefficient yokwandisa i-thermal ephantsi (i-CTE ephantsi) inokunciphisa i-warping ebangelwa yimiba yokushisa, kwaye inciphise ukuphuka kobhedu kwikona yomngxuma obangelwa ukwanda kwe-thermal, ngokukodwa kwiibhodi ze-PCB ezineemigangatho ezisibhozo okanye ngaphezulu, ukusebenza kwe-plated ngokusebenzisa imingxuma. ingcono kuneebhodi zePCB ezinamaxabiso eTG ngokubanzi.
I-3) Inokumelana neekhemikhali ezibalaseleyo, ukwenzela ukuba ibhodi ye-PCB ifakwe kwinkqubo yonyango emanzi kunye nezisombululo ezininzi zeekhemikhali, ukusebenza kwayo kusekho.
