Ukusuka kwi-PCB World,

Abantu abaninzi basebenzisa umbala wePCB ukwahlula umgangatho webhodi.Ngapha koko, umbala webhodi yomama awunanto yakwenza nokusebenza kwePCB.

PCB ibhodi, hayi ukuba phezulu ixabiso, kulula ukuyisebenzisa.

Umbala womphezulu we-PCB ngokwenene ngumbala we-solder ukumelana.Ukumelana ne-solder kunokuthintela ukwenzeka kwe-solder engalunganga yamacandelo, kunye nokulibazisa ubomi benkonzo yesixhobo, kwaye kuthintele i-oxidation kunye nokuhlwa kwesekethe yesixhobo.

Ukuba uyaziqonda iibhodi zePCB zeenkampani ezinkulu ezifana neHuawei kunye neZTE, uya kufumanisa ukuba umbala uluhlaza ngokubanzi.Oku kungenxa yokuba iteknoloji eluhlaza yeyona ikhulile kwaye ilula.

Ukongeza kokuluhlaza, umbala we-PCB unokuchazwa njenge "iintsimbi kunye neempempe": ezimhlophe, ezityheli, ezibomvu, eziluhlaza okwesibhakabhaka, imibala ye-matte, kunye nekrisanthemum, emfusa, emnyama, eluhlaza eqaqambileyo, njl njl. Ubukho bomhlophe, kuba Kuyimfuneko ukwenza iimveliso zokukhanyisa Imibala esetyenziswayo, kunye nokusetyenziswa kweminye imibala, ubukhulu becala isetyenziselwa ukuleyibheliza iimveliso.Kulo lonke inqanaba lenkampani ukusuka kwi-R&D ukuya kwimveliso, kuxhomekeke kusetyenziso olwahlukileyo lwePCB, ibhodi yovavanyo inokuba mfusa, ibhodi yezitshixo iya kuba bomvu, kwaye iibhodi zangaphakathi zekhompyuter ziya kuba mnyama, eziphawulwe. ngombala.

Ibhodi ye-PCB eqhelekileyo yibhodi eluhlaza, ebizwa ngokuba yi-oyile eluhlaza.I-inki yemaski yayo yeyona indala, inexabiso eliphantsi kwaye idumileyo.Ukongeza kwitekhnoloji evuthiweyo, ioyile eluhlaza ineenzuzo ezininzi:

Kwinkqubo yePCB, ukuveliswa kweemveliso zombane kubandakanya ukwenziwa kwebhodi kunye nokuchwethezwa.Ngexesha lenkqubo, kukho iinkqubo ezininzi zokuya kwigumbi lokukhanya elityheli, kwaye ibhodi yePCB eluhlaza ineyona mpembelelo ibonakalayo kwigumbi lokukhanya elityheli;okwesibini, kwi-SMT patch processing, i-tin isetyenziswa.Amanyathelo oku, ukuphetshwa kunye nolungelelwaniso lwe-AOI zonke zifuna ulungelelwaniso lwendawo yokubona, kunye nesixhobo sepleyiti esezantsi esiluhlaza sinobuhlobo ngakumbi ekuchongeni.

Inxalenye yenkqubo yokuhlola ixhomekeke kubasebenzi ukuba baqwalasele (kodwa ngoku uninzi lwabo lusebenzisa uvavanyo olubhabhayo lweprobe endaweni yencwadi yesandla), ukujonga ibhodi phantsi kokukhanya okuqinileyo, uhlaza lunobubele emehlweni.IiPCB eziluhlaza nazo zinobuhlobo ngakumbi nokusingqongileyo, kwaye aziyi kukhulula iigesi eziyityhefu xa ziphinda zisetyenziswe kumaqondo obushushu aphezulu.

Eminye imibala ye-PCB, efana ne-blue and black, i-doped kunye ne-cobalt kunye ne-carbon, ngokulandelanayo, ngenxa yokuba i-conductivity yombane ebuthathaka, kwaye kukho umngcipheko wesiphaluka esifutshane.

Thatha ibhodi emnyama njengomzekelo.Kwimveliso, ibhodi emnyama inokubangela ukungafani kombala ngenxa yenkqubo kunye neengxaki zempahla ekrwada, okukhokelela kwireyithi ye-PCB ephezulu.Umkhondo webhodi yesekethe emnyama ayilula ukuhlula, okuya kwandisa ubunzima bokugcinwa nokulungiswa kamva.Iifektri ezininzi zePCB azisebenzisi iiPCB ezimnyama.Nakwimimandla yoshishino lomkhosi kunye nolawulo lwamashishini, iimveliso ezineemfuno ezikumgangatho ophezulu kakhulu zisebenzisa i-PCB substrates eluhlaza.

Okulandelayo, makhe sithethe ngesiphumo sombala we-inki yemaski ebhodini?

Kwimveliso egqityiweyo, umphumo weenki ezahlukeneyo ebhodini ubonakaliswa ngokukodwa kwimbonakalo, oko kukuthi, nokuba kulungile okanye akunjalo.Ngokomzekelo, uhlaza lubandakanya ukukhanya kwelanga, ukukhanya okuluhlaza, okuluhlaza okumnyama, okuluhlaza okuluhlaza, njl., umbala ulula kakhulu, kulula ukubona iplagi Ukubonakala kwebhodi emva kwenkqubo yomngxuma ayilungile, kwaye abanye abavelisi ' i-inks ayilungile, umlinganiselo we-resin kunye nedayi yingxaki, kuya kubakho iingxaki ezinjengamaqamza, kwaye utshintsho oluncinci kumbala lunokubonwa;Impembelelo kwiimveliso ezigqityiweyo zibonakaliswa ikakhulu Ngokubhekiselele kubunzima bemveliso, le ngxaki inzima ukuyichaza.Ii-inki zemibala eyahlukeneyo zineenkqubo ezahlukeneyo zokufaka imibala, njengokutshiza nge-electrostatic, ukutshiza, kunye noshicilelo lwesikrini.Umlinganiselo we-inki ukwahluka.Impazamo encinci iya kubangela ukuba umbala uvele.ingxaki.

Nangona umbala we-inki awunasiphumo kwibhodi ye-PCB, ubukhulu be-inki bunempembelelo enkulu kwi-impedance, ngokukodwa kwibhodi yegolide yamanzi, enolawulo olungqongqo kakhulu kubukhulu be-inki;ubukhulu kunye namaqamza e-inki ebomvu kulula ukulawula, kwaye i-inki ebomvu igubungela Emgceni, ezinye iziphene zingagqunywa, kwaye ukubonakala kuhle kakhulu, kodwa into embi kukuba ixabiso libiza kakhulu.Xa umfanekiso, ukubonakaliswa obomvu kunye nophuzi kuzinzile, kwaye umhlophe kunzima kakhulu ukulawula.
