Yiziphi izimfuneko zekhwalithi zokwenziwa kwe-PCB?

Ukuthuthukiswa kwesayensi nobuchwepheshe bengxenye yezimboni kusobala ngokwengeziwe, imboni ye-elekthronikhi iyinsimu ephelele kakhulu njengamanje, ukuhwebelana kwembulunga yonke, ukumaketha, nokuphishekela ubuchwepheshe obusha obuphezulu kanye nezindleko eziphansi kuwumkhuba ongenakugwenywa wokuthuthukiswa kwe-electronics. imboni, enekhwalithi ephezulu kuphela nenzuzo yezindleko eziphansi,Ukwakhiwa kwe-PCBizinga izinga lezinga lomkhiqizo, iqoqo lekhwalithi, idumela, umthwalo wemfanelo namasiko, Kuwukuphishekela esihlale sikuphishekela.

Uma kukhulunywa ngekhwalithi, kungakhathaliseki ukuthi ibhodi lesifunda elinamacala amabili noma ibhodi lesifunda le-PCB elinezingqimba ezi-4 noma elinye.multi-layer PCB ephrintiwe wesifunda ibhodiizindaba zekhwalithi ezihlobene nolwazi lwamakhasimende.Amakhasimende akhathazeke kakhulu ngekhwalithi ye-PCB, ngakho-ke, yiziphi izidingo zekhwalithi ezijwayelekile zamafekthri webhodi lesifunda le-PCB?

Ukuthi amakhasimende anelisekile ngekhwalithi yemikhiqizo eyenziwe nge-PCB nokuthi imikhiqizo iyahlangabezana yini nezidingo zamakhasimende kuwukuphela kwendinganiso yokukala ikhwalithi yemikhiqizo.Ibhodi lesifunda eliphrintiwe liwuhlobo lomkhiqizo okhethekile wezinsimbi zikagesi, ikhasimende elilodwa, uhlobo olulodwa, uhlobo olulodwa lwebhodi.Ngokucutshungulwa kwedokhumenti ekhethekile yekhasimende, akukho mhlaba wonke.Lapho ibhodi le-PCB elinamaceleni amabili liyalelwa ikhasimende linqatshiwe, ibhodi lethu lesifunda elinezinhlangothi ezimbili lingachithwa kuphela, ngeke libe khona elinye ikhasimende elizokwamukela, kodwa nakuba zonke izinhlobo zehluzo zomugqa webhodi ephrintiwe zihlukile, usayizi wesakhiwo ohlukile, kodwa futhi babe ezivamile, ezivamile izidingo zayo eziyisisekelo.Izidingo zekhwalithi zefekthri yebhodi lesifunda ngokuvamile zimi kanje:

(1) Izidingo zokubukeka

Abahlinzeki bokwenza i-PCB ngokuvamile badinga ukubukeka okuqinile, okungadingi ukungcoliswa, ukufakwa, ukugxivizwa kweminwe kanye ne-oxidation ngaphezulu, ukuze bangathinti ukushisela kanye nokwahlukanisa.Umbala nombala wephethini ye-welding yokumelana kuyahambisana, ngaphandle kokuxebuka, ukulahleka noma ukuphambuka, i-seapage kawoyela, uma kwenzeka kuthinta i-welding.Unqenqema lwe-PCB lubushelelezi futhi luhlanzekile, ngaphandle kwe-bump noma i-burr, uma kwenzeka kuthikameza usayizi wenhlangano kanye nokufakwa.Ucingo olufanayo, akukho ukugqwala, notch, ithusi elisele, ukuvimbela umthelela wokusebenza kukagesi.Uphawu lukamaka lucacile, alunameki olufundekayo, ukuvimbela umthelela wokuhlanganisa nokugcinwa.Ayikho imihuzuko ebusweni ukugwema ukuthikameza umhlangano wokushisela nokusebenza kukagesi.Awekho amagwebu noma ama-delamination phakathi kwe-conductor noma izendlalelo ezivikelayo, ikakhulukazi ama-PCB anezingqimba eziningi, ukugwema ukuthikameza izakhiwo zikagesi.

(2) Izidingo zokusebenza kukagesi

Kubaluleke kakhulu ukusetha igebe elifanele likagesi phakathi kwezintambo zebhodi lesifunda elinezingqimba eziningi.Isikhala solayini esifanele singavimbela iflash kanye nokwehlukana phakathi kwamakhondakta afanelekile emsebenzini wokucubungula imikhiqizo ye-PCB, futhi kungaphasisa ngempumelelo ukuhlolwa kwamazinga okuphepha komkhiqizo afanelekile.Ezindinganisweni zezimboni nezokuphepha zebhodi lesifunda kanye nemikhiqizo ye-PCB, ama-voltage ahlukene okusebenza, izikhathi ezihlukene zokufaka izicelo nezinye izici zinemithetho ehlukene yegebe likagesi nebanga lokuqhekeka phakathi kwamakhondakta.

(3) Izidingo zokusebenza komshini

Ibhodi lesifunda lidinga ukuthi i-copper clad plate kufanele ibhakwe ngaphambi kokuvulwa ukuze kuqinisekiswe ukuthi i-resin volatilization resin yamanzi epuleti yelaphekile ngokuphelele;lapho uvula impahla, sebenzisa ngokuhambisana ngokuqinile ne-warp kanye nesiqondiso se-weft emfundweni yokuvula;ngesikhathi se-laminating kanye nokusethwa kwe-typesetting, i-laminating kanye nokuhlelwa kwezinhlobo kuzokwenziwa ngokuhambisana ne-warp kanye nezinkomba ze-weft zamapuleti asetshenziwe e-PCB.Izikhombisi-ndlela ze-warp ne-weft zizohlukaniswa kuqala bese ukuhlelwa kohlobo kuzoqhutshwa ngokuhambisana nezikhombisi-ndlela ezihlukile ze-warp ne-weft ukuze kuqinisekiswe ukuthi izikhombisi-ndlela ze-warp ne-weft ziyahambisana.Akukho ukulungiswa okuyimfihlo kwesikhathi sokucindezela okubandayo okuzovunyelwa, futhi amarekhodi azokwenziwa ukuze kuqinisekiswe ukuthi izingcindezi ezisemapuletini zikhululwa ngokuphelele futhi i-resin iselapheka ngokuphelele.Lapho uhlamvu lwebhodi lesifunda lebhodi lesifunda libhakwa ekushiseni okuphezulu, ishalofu lidinga ukulungiswa ngokuvumelana nobukhulu bebhodi.Ibhodi alivunyelwe ukugoba noma ukusonteka lapho isokhethi ifakiwe.Ubukhulu abufani nesokhethi elihlukile lokubhaka.

(4) Ukumelana nemvelo kanye nezinye izidingo zokusebenza

Ibhodi lesifunda elinezingqimba eziningi linokumelana nemvelo, ukumelana nesikhunta, ukumelana nomswakama, ukumelana nokupheka, ukumelana nomthelela wokushisa nezinye izakhiwo.

Ukwakhiwa kwekhwalithi yomkhiqizo we-PCB allegro kuhamba kuyo yonke inqubo yokwakhiwa komkhiqizo, futhi ikhwalithi yomkhiqizo we-PCB ihlobene nayo yonke inqubo yokukhiqiza.Yonke imboni yebhodi lesifunda kufanele inake ngokukhethekile ikhwalithi, ikhwalithi ikhiqizwa, hhayi ukuhlolwa.Zicabange njengomthengi wenqubo yangaphambilini kanye nenqubo elandelayo njengekhasimende lakho.Ngemuva kwebhodi lesifunda ngalinye kuneqembu labasebenzi abaqinisekisa ikhwalithi abaqhuba buthule ukuhlolwa kwekhwalithi, isistimu yokulawula ikhwalithi ephelele iyadingeka yiwo wonke abakhiqizi bokwenziwa kwe-PCB.

I-Huihe Circuits Co., Ltd. njengomhlinzeki wesevisi yokwenziwa kwe-PCB, imikhiqizo yebhodi lesifunda ye-PCB ihlanganisa ibhodi lesendlalelo esingu-2-28, ibhodi le-HDI, ibhodi lethusi eliphakeme le-TG eliwugqinsi,ibhodi le-flexible eliqinile, i-high frequency board, i-laminate medium exubile,abangaboni bangcwatshwe nge-PCB, ibhodi le-metal substrate kanye nebhodi lamahhala le-halogen.Imikhiqizo yebhodi lesifunda ye-PCB isetshenziswa kakhulu emishinini yokuxhumana, ikhompyutha, ukulawula izimboni, amandla kagesi, amathuluzi ezokwelapha, izinto zikagesi zokuphepha, ugesi wabathengi, ugesi wezimoto kanye neminye imikhakha yobuchwepheshe obuphezulu.Ingcweti kwezobuchwepheshe bemboni, ngemishini yokukhiqiza ethembekile, okokusebenza kokuhlola kanye nelabhorethri esebenzayo engokomzimba neyamakhemikhali.Ukuze uthole ulwazi olwengeziwe mayelana ne-PCB, sicela uvakashele Iwebhusayithi yethu.nomaXhumana nathi!
