Ngaphambi kokuklama ibhodi lesifunda eliphrintiwe, kuyadingeka ukunquma ukuthi usebenzise isendlalelo esisodwa noma i-PCB enezingqimba eziningi. Zombili izinhlobo zokuklama zivamile. Ngakho-ke yiluphi uhlobo olulungele iphrojekthi yakho? Uyini umehluko? Njengoba igama lisho, ibhodi elinesendlalelo esisodwa linesendlalelo esisodwa kuphela sesisekelo, esibizwa nangokuthi i-substrate, kuyilapho i-PCB enezingqimba eziningi inezingqimba eziningi.
Izinzuzo kanye nokusetshenziswa kwamabhodi ongqimba olulodwa
Amabhodi anongqimba olulodwa ngezinye izikhathi abizwa ngokuthi amabhodi anohlangothi olulodwa. Ngokuvamile, kunezingxenye ohlangothini olulodwa lwebhodi kanye nemikhondo yethusi ngakolunye uhlangothi. Ibhodi elinesendlalelo esisodwa liqukethe isendlalelo sesisekelo, isendlalelo sensimbi esiqhubayo, kanye nemaski evikelayo ye-solder. Ukwakhiwa kwesikrini sefilimu nosilika.

Izinzuzo kanye nokubi kwe-PCB yongqimba olulodwa
Izinzuzo: izindleko eziphansi, ukuklama okulula nokukhiqiza, isikhathi esifushane sokulethwa
Ukungalungi: Kumaphrojekthi ayinkimbinkimbi, ikakhulukazi uma inani lezingxenye likhulu, uma izidingo zesayizi zincane, iphaneli eyodwa ayikwazi ukuphatha umthamo ophansi wokusebenza, usayizi omkhulu, nesisindo esikhulu.

Uhlelo lokusebenza lwe-PCB yesendlalelo esisodwa
Iphaneli elilodwa seliyinketho ekhethwayo yemikhiqizo ehlukahlukene ye-elekthronikhi ngenxa yezindleko zayo eziphansi kanye nokukhiqizwa okulula. Nakuba amabhodi anezingqimba eziningi aya ngokuya ethandwa kakhulu njengoba ubuchwepheshe be-elekthronikhi buba nzima nakakhulu, amabhodi anongqimba olulodwa asasetshenziswa kabanzi. Ngokuvamile zivela kumadivayisi anomsebenzi owodwa futhi awadingi ukugcina inani elikhulu ledatha noma ukufinyelela inethiwekhi.
Ama-PCB anongqimba olulodwa ngokuvamile asetshenziswa ezintweni zikagesi ezincane zasendlini (njengemishini yekhofi). Futhi ziyi-PCB esetshenziswa kuzibali eziningi, imisakazo, amaphrinta namalambu e-LED. Amadivayisi okugcina alula njengamadrayivu e-solid-state ngokuvamile asebenzisa ama-PCB anohlangothi olulodwa, njengoba kwenza izingxenye ezifana nezinto ezinikezwa amandla kanye nezinhlobo eziningi ezahlukene zezinzwa.
Izinzuzo kanye nokusetshenziswa kwamabhodi anezingqimba eziningi
Ama-PCB anezingqimba eziningi enziwe ngamabhodi anezinhlangothi ezimbili noma amathathu apakishwe phezu kwelinye. Ngokuvamile, inani lezendlalelo zebhodi lezingqimba eziningi ngokuvamile liyinani elilinganayo lezendlalelo, phakathi kwezingqimba ezi-4 nezingu-12. Kungani ungasebenzisi inombolo eyinqaba yezendlalelo? Ngoba inombolo eyinqaba yezendlalelo izodala izinkinga ezifana ne-warpage kanye nokuhlanekezela ngemva kokushisela.
Kunezinsimbi eziqhutshwayo ezinhlangothini zombili zongqimba ngalunye lwe-substrate ebhodini le-multilayer. I-adhesive ekhethekile isetshenziselwa ukuxhuma lawa mabhodi ndawonye, futhi kukhona into evikelayo phakathi kwebhodi ngalinye. Emaphethelweni angaphandle ebhodi le-multilayer kukhona imaski ye-solder.
Amabhodi amaningi asebenzisa izimbobo ukwenza izendlalelo ezihlukene zixhumane. Ngokusebenzisa izimbobo ngokuvamile zihlukaniswa izigaba ezintathu:
Ngembobo: ngokusebenzisa ungqimba ngalunye lwebhodi lesifunda;
imbobo eyimpumputhe: xhuma ungqimba lwangaphandle kungqimba lwangaphakathi;
Ingcwatshwe nge: Xhuma izendlalelo ezimbili zangaphakathi, futhi azikwazi ukubonakala ngaphandle.

Izinzuzo kanye nokubi kwe-PCB ye-multilayer
Izinzuzo: ukwazi ukuphatha imisebenzi eyinkimbinkimbi, ikhwalithi ephezulu, amandla amakhulu, amandla amakhulu okusebenza kanye nesivinini esisheshayo, ukuqina okuthuthukisiwe, usayizi omncane nesisindo esincane.
Ukungalungi: izindleko eziphezulu, ukuklama nokukhiqiza okuyinkimbinkimbi, isikhathi eside sokulethwa, ukulungiswa okuyinkimbinkimbi.

Uhlelo lokusebenza lwe-Multilayer PCB
Ngokuthuthuka kobuchwepheshe, ama-PCB anezingqimba eziningi ayanda kakhulu. Imishini eminingi ye-elekthronikhi namuhla inemisebenzi eyinkimbinkimbi nosayizi abancane, ngakho-ke kufanele kusetshenziswe izingqimba eziningi kumabhodi azo wesifunda.
Amabhodi wesekethe aphrintiwe we-Multilayer avela ezingxenyeni eziningi zekhompiyutha, okuhlanganisa amabhodi omama namaseva. Kusukela kumakhompyutha aphathekayo namathebulethi kuya kumafoni ahlakaniphile namawashi ahlakaniphile. Amafoni ahlakaniphile ngokuvamile adinga izendlalelo ezingaba ngu-12. Eminye imikhiqizo ayiyona inkimbinkimbi njengama-smart phone, kodwa iyinkimbinkimbi kakhulu kumabhodi esekethe aphrintiwe ohlangothini olulodwa, ngokuvamile asebenzisa izendlalelo ezi-4 kuye kweziyisi-8. Okufana nama-oven microwave nama-air conditioners.
Ukwengeza, ngenxa yokuthembeka, usayizi omncane kanye nomklamo ongasindi odingwa yimishini yezokwelapha, ngokuvamile angagijima ebhodini elinezingqimba ezingaphezu kwezintathu. Amabhodi wesifunda aphrintiwe we-Multilayer nawo asetshenziswa emishinini ye-X-ray, iziqapha zenhliziyo, imishini yokuskena ye-CAT nezinye izinhlelo zokusebenza eziningi.
Izimboni zezimoto kanye ne-aerospace nazo ziya ngokuya zisebenzisa izingxenye ze-elekthronikhi ezihlala isikhathi eside nezingasindi, futhi lezi ngokuvamile zisebenzisa amabhodi ezendlalelo eziningi. Lezi zingxenye kumele zikwazi ukumelana nokugqoka, izinga lokushisa eliphezulu nezinye izimo ezinzima. Amakhompuyutha asebhodini, izinhlelo ze-GPS, izinzwa zenjini, namaswishi amalambu angaphambili ngokuvamile nawo asebenzisa amabhodi anezinhlaka eziningi.
Ungasithola kanjani isidingo se-PCB enesendlalelo esisodwa noma enezingqimba eziningi
Ukuze unqume ukuthi iphrojekthi yakho idinga ungqimba olulodwa noma ibhodi lesifunda eliphrintiwe le-multilayer, udinga ukucabangela izidingo zephrojekthi kanye nohlobo olufaneleka kakhulu. Zibuze imibuzo emihlanu elandelayo:
1. Iliphi izinga lokusebenza engilidingayo? Uma iyinkimbinkimbi kakhulu, kungase kudingeke izendlalelo eziningi.
2. Yimuphi usayizi omkhulu webhodi? Amabhodi anezingqimba eziningi angakwazi ukwamukela imisebenzi eyengeziwe endaweni encane.
3. Ingabe ukuqina kunikezwa kuqala? Uma kunjalo, sebenzisa izendlalelo eziningi.
4. Ithini ibhajethi yami? Ukuze uthole ibhajethi enesizotha, amabhodi anesendlalelo esisodwa asebenza kahle kakhulu.
5. Ngidinga i-PCB ngokushesha kangakanani? Uma kuqhathaniswa namabhodi esekethe aphrintelwe izendlalelo eziningi, amabhodi esekethe aphrintelwe isendlalelo esisodwa anesikhathi esifushane sokuhola.
