Umahluko phakathi kwePCB kunye nendibano yePCB

Yintoni PCBA

PCBA sisishunqulelo seindibano yebhodi yesiphaluka eprintiweyo.Kuthetha ukuba, ii-PCB ezingenanto zihamba kuyo yonke inkqubo ye-SMT kunye ne-DIP plug-in.

I-SMT kunye ne-DIP zombini ziindlela zokudibanisa iinxalenye kwibhodi yePCB.Umahluko ophambili kukuba i-SMT ayifuni gqobhoza imingxuma kwibhodi yePCB.Kwi-DIP, kufuneka ufake i-PIN kumngxuma ogrunjiweyo.

Yintoni i-SMT (iTekhnoloji eFakelwe phezulu)

ITekhnoloji yoMphezulu oNyuliweyo ikakhulu usebenzisa umatshini wokunyusela ukunyusela iinxalenye ezincinci kwibhodi yePCB.Inkqubo yemveliso yile: Ukubekwa kwebhodi yePCB, ukuncamathelisa i-solder yokushicilela, ukunyuswa komatshini, isithando somlilo sokufudumeza kunye nokuhlolwa okugqityiweyo.Ngophuhliso lwenzululwazi kunye nobuchwepheshe, i-SMT inokuphinda ifake iindawo ezinobungakanani obukhulu, obunje: ezinye iinxalenye zesixhobo sobungakanani obukhulu zinokuxhonywa kwi-motherboard.

Indibano ye-SMT PCBudibaniso lunovakalelo kwindawo kunye nobukhulu benxalenye.Ukongeza, umgangatho we-solder paste kunye nomgangatho wokushicilela nawo udlala indima ephambili.

I-DIP yi-“plug-in”, oko kukuthi iinxalenye ze-PCB board.Ngenxa yobukhulu bamacandelo bukhulu kwaye ayifanelekanga ukunyuswa okanye xa umenzi engakwazi ukusebenzisa iteknoloji yokudibanisa i-SMT, kwaye iplagi isetyenziselwa ukudibanisa iindawo.Okwangoku, kukho iindlela ezimbini zokuqaphela iplagi-in kunye ne-robot plug-in kwishishini.Iinkqubo eziphambili zemveliso zezi: ukuncamathela ngasemva iglu (ukuthintela ukucakwa kwetoti kwindawo ekungafuneki ukuba ifakwe kuyo), iplagi-in, uhlolo, i-wave soldering, i-plate brushing (ukususa amabala asele kwinkqubo yokudlula kwesithando somlilo) kwaye igqityiwe. ukuhlolwa.

Yintoni iPCB

I-PCB ithetha ibhodi yesekethe eprintiweyo, ekwabizwa ngokuba yibhodi yocingo eprintiweyo.I-PCB yinxalenye ebalulekileyo ye-elektroniki, ikwayinkxaso yamacandelo e-elektroniki kunye nomthwali woqhagamshelo lombane lwamalungu e-elektroniki.Ngenxa yokuba yenziwe ngoshicilelo lwe-elektroniki, kwaye ibizwa ngokuba yibhodi yesekethe eprintiweyo.

Emva kokusebenzisa i-PCB yezixhobo zombane, ngenxa yokungaguquguquki kohlobo olufanayo lwePCB, impazamo yocingo yesandla inokuthintelwa, kwaye izinto ze-elektroniki zinokufakwa okanye zincamatheliswe ngokuzenzekelayo, zithengiswe ngokuzenzekelayo, kwaye zibhaqwe ngokuzenzekelayo, ukuze kuqinisekiswe umgangatho. wezixhobo zombane, nokuphucula imveliso yabasebenzi, ukunciphisa iindleko nokuququzelela ulondolozo.

I-PCB inokusetyenziswa ngokubanzi nangaphezulu, kuba ineenzuzo ezininzi ezizodwa:

1. Uxinaniso oluphezulu: Kangangamashumi eminyaka, ukuxinana okuphezulu kwePCB kunokuphuhlisa ngokuphuculwa kokuhlanganiswa kwe-IC kunye nokufakwa kweteknoloji.
2. Ukuthembeka okuphezulu.Ngoluhlu lokuhlola, uvavanyo kunye novavanyo lokuguga, i-PCB inokusebenza ngokuthembekileyo ixesha elide (iminyaka eyi-20 ngokubanzi).
3. ŸUkuyilwa.Kwiimfuno zentsebenzo ye-PCB (umbane, umzimba, iikhemikhali, oomatshini, njl. njl.), uyilo lwePCB lunokuphunyezwa ngokuyila 4. Ukulinganisa, ukulinganisa, njl., kunye nexesha elifutshane kunye nokusebenza okuphezulu.
5. Ukuvelisa.Ngolawulo lwangoku, ukulinganisa, isikali (ubuninzi), i-automation kunye neminye imveliso inokuqhutyelwa ukuqinisekisa ukuhambelana komgangatho wemveliso.
6. ŸUzinzo.Kusekwe indlela yovavanyo epheleleyo, imigangatho yovavanyo, izixhobo ezahlukeneyo zovavanyo kunye nezixhobo zokubona nokuchonga isiqinisekiso semveliso yePCB kunye nobomi benkonzo.
7. ŸUkudityaniswa.Iimveliso ze-PCB azilungele kuphela ukuhlanganisana okusemgangathweni kwamacandelo ahlukeneyo, kodwa kunye nemveliso ezenzekelayo kunye nenkulu enkulu.Kwangaxeshanye, iPCB kunye neenxalenye ezahlukeneyo zendibano yecandelo zinokudityaniswa zenze iinxalenye ezinkulu, iinkqubo, kunye nomatshini wonke.
8. ŸUkugcinakala.Iimveliso zePCB kunye neenxalenye ezahlukeneyo zendibano yecandelo ziyilelwe kwaye ziveliswe ngokwemigangatho, ezi ndawo nazo zisemgangathweni.Ngoko ke, xa inkqubo ingaphumeleli, inokutshintshwa ngokukhawuleza, ngokufanelekileyo kunye nokuguquguqukayo, kwaye inkqubo inokubuyiselwa ngokukhawuleza.Kakade ke, kukho imizekelo emininzi.Njengokwenza inkqubo encinci ye-miniaturization, i-lightweight, i-high-speed signal transmission kunye nokunye.

Yintoni umahluko phakathi PCB kunye PCBA

1. I-PCB ibhekisa kwibhodi yesekethe, ngelixa i-PCBA ibhekisa kwindibano yeplagi yebhodi yesekethe, inkqubo ye-SMT.
2. Ibhodi egqityiweyo kunye nebhodi engenanto
3. I-PCB yibhodi yesekethe eprintiweyo, eyenziwe nge-epoxy glass resin.Yahlulahlulwe yaba yi-4, 6 kunye ne-8 umaleko ngokwemigangatho yemiqondiso eyahlukeneyo.Eyona nto ixhaphakileyo yi-4 kunye ne-6-layer 4. iibhodi.I-Chip kunye nezinye i-patch elements zincanyathiselwe kwi-PCB.
5. I-PCBA inokuqondwa njengebhodi yesekethe egqityiweyo emva kokuba inkqubo kwibhodi yesekethe igqityiwe kwaye ingabizwa ngokuba yi-PCBA.
6. PCBA=IBhodi yeSekethe eShicileleyo +Indibano
7. Ii-PCB ezingenanto zihamba kuyo yonke inkqubo ye-SMT kunye ne-dip plug-in, ibizwa ngokuba yi-PCBA ngokufutshane.

PCB sisishunqulelo sebhodi yesekethe eprintiweyo.Ngokuqhelekileyo kubizwa ngokuba yisekethe eprintiweyo eyenziwe ngesekethe eprintiweyo, amacandelo aprintiweyo okanye ipateni yokuqhuba eyenziwe ngokudityaniswa kwebhodi yesekethe eprintiweyo kunye nebhodi yesekethe eprintiweyo.Ipatheni yokuqhuba ebonelela ngoqhagamshelo lombane phakathi kwamacandelo kwi-insulating substrate ibizwa ngokuba yisekethe eprintiweyo.Ngale ndlela, isekethe eprintiweyo okanye ibhodi egqityiweyo yesekethe eprintiweyo ibizwa ngokuba yibhodi yesekethe eprintiweyo, ebizwa ngokuba yibhodi yesekethe eprintiweyo okanye ibhodi yesekethe eprintiweyo.

Akukho malungu kwi-PCB eqhelekileyo, edla ngokubizwa ngokuba yi-“printed wiring board (PWB)”
