Zeziphi iimpawu ibhodi umaleko pcb kabini kunye multi-maleko wesekethe ibhodi kunye nendlela ukwahlula kubo? Masilandele abathengisi ibhodi pcb:

Maleko kabini ibhodi pcb

Iibhodi ezinamacala amabini zinentambo kumacala omabini, kodwa ukusebenzisa omabini amacingo, kufuneka kubekho unxibelelwano olufanelekileyo lombane phakathi kwala macala mabini. Le "bhulorho" phakathi kweesekethe ibizwa ngokuba ngumngxunya wesikhokelo (VIA). umngxunya omncinci kwi-PCB, ezaliswe okanye egutyungelwe sisinyithi, enokuqhagamshelwa ngocingo kumacala omabini, kuba iipaneli eziphindwe kabini zinendawo ephindwe kabini yendawo yepaneli enye, kwaye ngenxa yokuba iintambo zinokungenelela (ezinokuthi zenzakaliswe zijikeleze kwelinye icala), kulunge ngakumbi kwiisekethe ezintsonkothileyo kunepaneli enye.

Iphaneli yobuchwephesha bobuchwephesha luhlobo lwebhodi yesekethe ye-PCB ebaluleke kakhulu kuyo, iyinjongo enkulu, ukubona ukuba ibhodi yeBhodi yeBhodi yeBhodi ephindwe kabini ilula, ukuqonda kwepaneli enye ikholelwa ngokupheleleyo ukuba abahlobo banokuqonda, lulwandiso Iphaneli enye ithetha ukuba iphaneli enye ithetha ukuba iphaneli enye yanele ngokwaneleyo ukuya kwelinye icala, iphaneli ephindwe kabini, kwaye bekukho into ebalulekileyo ngumngxunya wesikhokelo.Ingongoma elula kukuba umgca wamacala amabini, omabini amacala omgca! Ibhrakethi yile: ibhodi yomgca wamacala amabini iphaneli kabini! Abanye abahlobo baya kubuza njengebhodi enamacala amabini, kodwa icala elinye kuphela linamalungu e-elektroniki, ibhodi enjalo emva kwayo yonke iphaneli kabini okanye iphaneli enye? Impendulo icacile , Ibhodi enjalo yiphaneli ephindwe kabini, kwibhodi yephaneli ephindwe kabini ebekwe kumacandelo.

Iibhodi zesekethe zemultilayer zilula ukwahlula

Ibhodi yesekethe ngokuthatha isigqibo sokuba ingakanani inkqubo ye-wiring enobunzima kunye nexabiso lokuchwetheza, ibhodi yesekethe eqhelekileyo enelayini enye kunye nomgca ophindwe kabini, eyaziwa njengephaneli enye kunye nepaneli kabini, iimveliso eziphezulu zombane, nangona kunjalo, ngenxa yoyilo lwesithuba semveliso , ukongeza kwintambo yombane, isekethe yangaphakathi yesekethe ye-multilayer, inkqubo yemveliso, yenze umaleko ngamnye emva komgca, kwakhona ngokubekwa kwesixhobo se-optical, ucofa, vumela indawo ephezulu yesekethe eyahlukeneyo kwisiqwenga sebhodi yesekethe. Ibhodi yesekethe engaphezulu okanye elingana neelayile ezi-2 kunokuthiwa yibhodi yesekethe emininzi.Ibhodi yesekethe emininzi inokuhlulwa ibe yibhodi yesekethe enzima, ibhodi yesekethe ethambileyo kunye nebhodi yesekethe, -ibhodi yesekethe ethambileyo kunye nobunzima edibeneyo.

Ukuzalwa kwebhodi yesekethe ye-multilayer

Ukuqina koxinano lweephakeji ze-IC kukhokelela kuxinzelelo oluphezulu lonxibelelwano, olunyanzelisa ukuba kusetyenziswe ii-substrates ezininzi. Ngokucacileyo, kwipaneli enye, okanye kwiphaneli ephindwe kabini, ezi mfuno azinakuphendulwa ngokwanelisayo ngenxa yenani eliqingqiweyo lokuwela elinokuphunyezwa Kwimeko yenani elikhulu lonxibelelwano. kunye neemfuno zomnqamlezo, ubeko lwebhodi kufuneka lwandiswe lube ngaphezulu kwamanqanaba amabini ukufezekisa ukusebenza okwanelisayo Ke ngoko, eyona njongo iphambili yeebhodi zesekethe ezininzi ezinobubanzi kukubonelela ngenkululeko ethe kratya kwiisekethi ezintsonkothileyo kunye / okanye ezinengxolo. Ibhodi yesekethe ye-multilayer ineengqimba ezintathu zokuqhuba, ezimbini zazo zinomphezulu wangaphandle, kwaye umaleko oseleyo Ukudityaniswa kombane phakathi kwabo kuhlala kwenziwa ngokufaka imingxunya kwicandelo lomnqamlezo webhodi yesekethe.Iibhodi zesekethe eziprintiweyo ezininzi, njengeepaneli eziphindwe kabini, zihlala zitywinwe ngamacwecwe e-orifice ngaphandle kokuba kuboniswe ngenye indlela.

Ii-multilaminates zenziwe ngokubeka iiseti zeesekethe ngaphezulu kwesinye nangaphezulu, ngonxibelelwano oluthembekileyo lwangaphambi kokusetwa phakathi kwazo.Kuba ukubhola kunye nokwenza i-electroplating kwenziwa ngaphambi kokuba zonke izinto ziqengqwe kunye, obu buchule bophula inkqubo yokuvelisa yemveli kwasekuqaleni Amacwecwe amabini angaphakathi enziwe ngeepaneli zemveli eziphindwe kabini, ngelixa amanqwanqwa angaphandle enziwe ngeepaneli ezizodwa ngaphambi kokuba ziqengqwe, iipleyiti zangaphakathi ziya kugrunjelwa, zifakwe ngaphakathi kwimingxunya, zigqithiselwe ngokomzobo, ziphuhliswe kwaye zimiswe. Umaleko womngxunya ngumaleko womqondiso, odityaniswe ngohlobo lokuba wenze umsesane wobhedu olungeleleneyo kumngxunya ongaphakathi womngxunya. Iileya ziyaqengqelwa kunye ukwenza uninzi lwesahlulo, esinokudityaniswa ngu I-wave soldering.

Ukuxinana kunokwenziwa kumatshini wokushicilela we-hydraulic okanye kwigumbi loxinzelelo (i-autoclave) .Umatshini wokushicilela we-hydraulic, izinto ezilungiselelwe (zoxinzelelo lwezinto) zibekwa phantsi koxinzelelo olubandayo okanye olushushu ngaphambili (umxholo wobushushu beglasi obuphezulu ubekwe kwindawo Ubushushu beglasi lobushushu bubushushu apho indawo ye-amorphous ye-polymer (i-resin) okanye inxenye ye-crystalline polymer itshintsha ukusuka kwimeko enzima, kunokuba ibukrelekrele iye kwilizwe le-viscous, irabha.

Ii-multilaminates zisetyenziswa kwizixhobo ezikhethekileyo ze-elektroniki (iikhompyuter, izixhobo zasemkhosini), ngakumbi kwimeko yobunzima kunye nokugcwala kakhulu, nangona kunjalo, oku kunokufezekiswa ngokunyusa iindleko ze-laminates endaweni yokufumana indawo engaphezulu kunye nobunzima obuncinci. isantya seesekethe, ii-laminates zikwanceda kakhulu njengoko zibonelela abaqulunqi beebhodi zesekethe eziprintiweyo nangaphezulu kwesibini seebhodi zeewiring kwaye zibonelela ngemimandla emikhulu yomhlaba kunye namandla.

Oku kungasentla kukuba ukwahlula indlela ibhodi yesekethe kabini-enamehlo multi-umaleko ibhodi zeesekethe, ndiyathemba ukuba ungathanda, Thina abavelisi ibhodi wesiphaluka , Wamkelekile ukubuza ~
