Indlela yokukhiqiza yamabhodi we-multilayer ngokuvamile yenziwa ihluzo zesendlalelo sangaphakathi kuqala, bese ngokuphrinta nokunamathisela indlela yokwenza i-substrate ehlangothini olulodwa noma enezinhlangothi ezimbili, futhi ibe isendlalelo esinqunyiwe phakathi, bese ngokushisa, ukucindezela nokuhlanganisa, ngokuqondene nokubhola okulandelayo kuyafana nendlela yokucwenga ezinhlangothini ezimbili.
1. Okokuqala, ibhodi lesekethe le-FR4 kumele lenziwe kuqala.Ngemva kokumboza ithusi elinezimbobo ku-substrate, izimbobo zigcwaliswa nge-resin futhi imigqa yangaphezulu yakhiwe ngokuchotshozwa okukhiphayo.Lesi sinyathelo siyafana nebhodi elijwayelekile le-FR4 ngaphandle kokugcwaliswa kwe-perforations nge-resin.
2. I-photopolymer epoxy resin isetshenziswa njengesendlalelo sokuqala se-insulation FV1, futhi ngemva kokumiswa, i-photomask isetshenziselwa isinyathelo sokuchayeka, futhi ngemva kokuchayeka, i-solvent isetshenziselwa ukuthuthukisa imbobo engezansi yembobo yesikhonkwane.Ukuqina kwe-resin kwenziwa ngemuva kokuvulwa komgodi.
3. I-epoxy resin surface yenziwa roughed by permanganic acid etching, and after etching, ungqimba lwethusi kwakheka phezulu ngocwecwe lwethusi olungenawo ugesi lwesinyathelo esilandelayo sokucwebezelisa ithusi.Ngemuva kokucwenga, ungqimba lwe-copper conductor luyakhiwa futhi isendlalelo sesisekelo sakhiwe nge-subtractive etching.
4. Imbozwe ngongqimba lwesibili lwe-insulation, isebenzisa izinyathelo ezifanayo zokuthuthukisa ukuchayeka ukwakha imbobo yebhawodi ngaphansi kwembobo.
5. Uma isidingo se-perforation, ungasebenzisa ukubhoboza izimbobo ukuze wenze ama-perforations emva kokwakhiwa kwe-copper electroplating etching ukwakha ucingo.
oqwembeni olungaphandle lwebhodi lesifunda elimbozwe ngopende we-anti-tin, kanye nokusetshenziswa kwendlela yokuthuthukisa ukuchayeka ukuveza ingxenye yokuxhumana.
6. Uma inani lezendlalelo likhuphuka, ngokuyisisekelo vele uphinde izinyathelo ezingenhla.Uma kunezingqimba ezengeziwe ezinhlangothini zombili, ungqimba lokufakelwa kufanele luboshwe ezinhlangothini zombili zesendlalelo sesisekelo, kodwa inqubo yokufaka ingenziwa ezinhlangothini zombili ngesikhathi esifanayo.
