Phambi kokuyila ibhodi yesekethe eprintiweyo, kuyimfuneko ukugqiba ukuba usebenzisa umaleko omnye okanye multi-layer PCB. Zombini iintlobo zoyilo ziqhelekileyo. Ke loluphi uhlobo olulungele iprojekthi yakho? Yintoni umahluko? Njengoko igama lisitsho, ibhodi yomgangatho omnye inomaleko omnye kuphela wesiseko, ekwabizwa ngokuba yi-substrate, ngelixa i-PCB ye-multilayer ineleya ezininzi.
Izinto eziluncedo kunye nokusetyenziswa kweebhodi zoluhlu olulodwa
Iibhodi ezinomaleko omnye ngamanye amaxesha zibizwa ngokuba ziibhodi ezicalanye. Ngokuqhelekileyo, kukho amacandelo kwelinye icala lebhodi kunye nemikhondo yobhedu kwelinye icala. Ibhodi ye-single-layer iqukethe isiseko sesiseko, i-metal conductive layer, kunye ne-mask solder ekhuselayo. Ifilimu kunye nokwakheka kwesikrini sesilika.

Izinto eziluncedo kunye nezingeloncedo kwi-PCB eyodwa
Izinto eziluncedo: ixabiso eliphantsi, uyilo olulula kunye nemveliso, ixesha elifutshane lokuhambisa
Ukungalungi: Kwiiprojekthi eziyinkimbinkimbi, ngakumbi xa inani lamacandelo likhulu, ukuba iimfuno zobukhulu zincinci, iphaneli enye ayikwazi ukuphatha umthamo ophantsi wokusebenza, ubungakanani obukhulu kunye nobunzima obukhulu.

Isicelo esisodwa se-PCB
Iphaneli enye iye yaba lolona khetho lukhethwayo kwiimveliso ezahlukeneyo ze-elektroniki ngenxa yexabiso eliphantsi kunye nokuveliswa okulula. Nangona iibhodi ezinamaleko amaninzi zisiya zithandwa ngakumbi njengoko itekhnoloji ye-elektroniki iya isiba nzima ngakumbi, iibhodi ezinomaleko omnye zisasetyenziswa ngokubanzi. Ngokuqhelekileyo zivela kwizixhobo ezinomsebenzi omnye kwaye akufuneki ukugcina inani elikhulu ledatha okanye ukufikelela kwinethiwekhi.
Ii-PCB ezikumgangatho omnye zidla ngokusetyenziswa kwizixhobo ezincinci zasekhaya (ezifana noomatshini bekofu). ZikwayiPCB esetyenziswa kwiikhaltyhuleyitha ezininzi, oonomathotholo, abashicileli kunye nezibane ze-LED. Izixhobo zokugcina ezilula ezifana ne-slid-state drives zihlala zisebenzisa ii-PCB ezicalanye, njengoko kwenza amacandelo afana nombane kunye neentlobo ezininzi ezahlukeneyo zezivamvo.
Izinto eziluncedo kunye nokusetyenziswa kweebhodi ezininzi
Ii-PCB ezinomaleko amaninzi zenziwe ngeebhodi ezintathu okanye ngaphezulu ezinamacala amabini ezibekwe phezu kwenye. Ngokuqhelekileyo, inani leeleya zebhodi ye-multilayer ngokuqhelekileyo linani elilinganayo leeleya, phakathi kwe-4 kunye ne-12 yomaleko. Kutheni ungasebenzisi inani elingumnqakathi lamaleya? Ngenxa yokuba inani elingaqhelekanga leeleya liya kubangela iingxaki ezifana ne-warpage kunye nokuphazamiseka emva kwe-welding.
Kukho iintsimbi eziqhubayo kumacala omabini omaleko we-substrate nganye kwibhodi ye-multilayer. I-adhesive ekhethekileyo isetyenziselwa ukudibanisa ezi bhodi kunye, kwaye kukho i-insulating material phakathi kwebhodi nganye. Kumda ongaphandle webhodi ye-multilayer kukho imaski ye-solder.
Iibhodi ezininzi zisebenzisa ngemingxunya ukwenza iileya ezahlukeneyo zinxibelelane. Ngemingxuma yohlulwe ngokubanzi ngokweendidi ezintathu:
Ngomngxuma: ngomaleko ngamnye webhodi yesekethe;
umngxuma oyimfama: qhagamshela umaleko wangaphandle kwinqanaba elingaphakathi;
Ungcwatywa nge: Qhagamshela iileya ezimbini zangaphakathi, kwaye azinakubonwa ngaphandle.

Izinto eziluncedo kunye nezingeloncedo kwi-PCB yamanqanaba amaninzi
I-Advantages: iyakwazi ukusingatha imisebenzi enzima ngakumbi, umgangatho ophezulu, amandla amakhulu, amandla amakhulu okusebenza kunye nesantya esikhawulezayo, ukuqina okuphuculweyo, ubungakanani obuncinci kunye nobunzima obulula.
Ukungalungi: ixabiso eliphezulu, uyilo olunzima kunye nemveliso, ixesha elide lokuhambisa, ukugcinwa okunzima ngakumbi.

Usetyenziso lwePCB yemultilayer
Ngokuhambela phambili kwetekhnoloji, iiPCB ezininzi ziye zaxhaphaka ngakumbi. Izixhobo ezininzi zombane namhlanje zinemisebenzi enzima kunye nobukhulu obuncinci, ngoko ke kufuneka kusetyenziswe iileya ezininzi kwiibhodi zesekethe.
Iibhodi zesekethe eziprintiweyo ezininzi zivela kumacandelo amaninzi ekhompyuter, kubandakanya iibhodi zoomama kunye neeseva. Ukusuka kwiilaptops kunye neetafile ukuya kwii-smartphones kunye neewotshi ezihlakaniphile. Iifowuni ze-Smart zidla ngokufuna iileya ezili-12. Ezinye iimveliso azinzima njengeefowuni ezihlakaniphile, kodwa zinzima kakhulu kwiibhodi zesekethe eziprintiweyo kwicala elinye, ngokuqhelekileyo zisebenzisa i-4 ukuya kwi-8 layers. Njengee-oveni ze-microwave kunye ne-air conditioners.
Ukongeza, ngenxa yokuthembeka, ubungakanani obuncinci kunye noyilo olulula olufunwa zizixhobo zonyango, banokuqhuba ngokuqhelekileyo kwibhodi enemigangatho engaphezu kwezintathu. Iibhodi zesekethe eziprintiweyo ezininzi zikwasetyenziswa koomatshini beX-reyi, iimonitha zentliziyo, izixhobo zokuskena zeCAT kunye nezinye iinkqubo ezininzi.
Amashishini eemoto kunye ne-aerospace nawo asebenzisa izinto ze-elektroniki ezomeleleyo kunye nezikhaphukhaphu, kwaye ezi zisebenzisa iibhodi ezininzi. Ezi zixhobo kufuneka zikwazi ukumelana nokugqoka, ukushisa okuphezulu kunye nezinye iimeko ezinzima. Iikhompyuter ezisebhodini, iinkqubo zeGPS, izivamvo ze-injini, kunye nokutshintsha kwesibane esikhulu ngokuqhelekileyo zisebenzisa iibhodi ezininzi.
Indlela yokumisela imfuno yomaleko omnye okanye iPCB enamaleko amaninzi
Ukuze unqume ukuba iprojekthi yakho idinga ibhodi yesekethe eprintiweyo enye okanye ibhodi yesekethe eprintiweyo, kufuneka uqwalasele iimfuno zeprojekthi kunye nohlobo olufanelekileyo. Zibuze le mibuzo mihlanu ilandelayo:
1. Leliphi inqanaba lokusebenza endilidingayo? Ukuba intsonkothe ngakumbi, kungafuneka iileya ezininzi.
2. Yintoni ubukhulu bobungakanani bebhodi? Iibhodi zeMultilayer zinokuthatha imisebenzi emininzi kwindawo encinci.
3. Ngaba ukomelela kunikwa indawo yokuqala? Ukuba kunjalo, sebenzisa iileya ezininzi.
4. Ithini ibhajethi yam? Kuhlahlo lwabiwo-mali oluphantsi, iibhodi ezinoluhlu olunye zisebenza kakuhle.
5. Ndiyifuna ngokukhawuleza kangakanani iPCB? Xa kuthelekiswa neebhodi zeesekethe eziprintiweyo ezininzi, iibhodi zeesekethe eziprintiweyo zodwa zinexesha elifutshane lokukhokela.
