Izinselelo Ekwenziweni Kwe-Copper Coin PCB nokuthi Ungakunqoba Kanjani

Ubuchwepheshe be-PCB yezinhlamvu zethusi buhlinzeka ngokusatshalaliswa kokushisa okuphezulu kakhulu kwezicelo zamandla aphezulu ngokufaka izinhlamvu zemali zethusi ezijiyile ngqo ezingqimbeni ze-dielectric. Ngenkathi ukwenziwa kwe-PCB yezinhlamvu zethusi kufeza ukuqhutshwa kokushisa okudlula kakhulu imiklamo evamile, inqubo yokukhiqiza iletha izinselele ezinkulu kufaka phakathi ukuqongelela kokucindezeleka kokushisa, ukwakheka kwe-interface void, kanye nezinkinga zokulawula ubukhulu. Ukubhekana nalezi zinkimbinkimbi kudinga ukulungiswa kwenqubo ehlelekile ukuqinisekisa ikhwalithi ehambisanayo kanye nokuthembeka ezindaweni zokukhiqiza.

Ukuqonda I-Copper Coin PCB Fabrication Complexity

Ubunkimbinkimbi obuyisisekelo bokwenziwa kwe-PCB yohlamvu lwemali yethusi busukela ekushumekeni izinhlamvu zemali zethusi eziqinile phakathi kwemigodi egayiwe esikhundleni sokusebenzisa ucwecwe lwekhopha olujwayelekile. Lokhu kudala izinselele zokusebenzelana kwezinto phakathi kwezinhlamvu zemali zethusi, i-prepreg resin, i-FR4 substrate, nezendlalelo ze-foil yethusi, ngayinye ibonisa ama-coefficients ahlukene wokunwetshwa okushisayo. Ukucutshungulwa kwemishini kudinga ukubekezelelana okuqinile kokujula komgodi, ukunemba kokubekwa kohlamvu lwemali, kanye nemisebenzi yokumba elandelayo. Lokhu kusebenzisana kwezinto eziningi kusungula isisekelo se-delamination ye-interface, i-void entrapment, kanye nokugxila kwengcindezi okuthinta ngokuqondile ukusebenza okushisayo nokuthembeka kwesikhathi eside.

Izinselele Ezibalulekile Ekwenzeni I-Copper Coin PCB

1. Ukwakheka Okungenalutho kanye Nokulawula Ukugeleza Kwe-resin

Ukwakheka okuyize kumelela isici esibucayi kakhulu ekwenziweni kwe-PCB yohlamvu lwemali yethusi, okwenzeka lapho i-prepreg resin yehluleka ukugcwalisa ngokuphelele izikhala ezingaphansi noma igeleza ngokulinganayo ezungeze izinhlamvu zemali ezishumekiwe. Ingcindezi ye-vacuum enganele, okuqukethwe kwe-resin okungalungile, noma izici zokugeleza ezinganele kudala amaphakethe omoya ezindaweni ezishisayo ezikhulisa kakhulu ukumelana nokushisa futhi zidale izindawo zokugxilisa ingqondo.

Izixazululo eziyinhloko zokuvimbela i-void:

• Okulungiselelwe okuqukethwe kwe-resin prepreg kanye namaphrofayili e-viscosity - Iqinisekisa ukugcwaliswa okuphelele kwe-cavity ngesikhathi sokucwiliswa
• Izinqubo ze-vacuum-assisted lamination - Isusa umoya ovalelwe ezindaweni ezibucayi
• Isofthiwe yokulingisa ukugeleza kwe-resin - Ibikezela ukugcwalisa iziphambeko ngaphambi kokukhiqiza

2. I-Copper Coin Surface Ukulungiselela kanye nokuhlanganisa

I-oxidation yendawo kanye nokungcoliswa kwezinhlamvu zemali zethusi kuphazamisa kakhulu amandla okunamathela phakathi kwethusi ne-resin matrix. Ngisho nezingqimba ezincane ze-oxide zakha izixhumanisi ezibuthakathaka eziholela ekudambiseni ngesikhathi sokucindezeleka okushisayo, ziphule ngokuphumelelayo indlela yokuqhuba okushisayo.

Izindlela zokwelapha eziyisisekelo:

• Ukususwa kwe-Chemical oxide ngokushesha ngaphambi kokuqothula - Iqinisekisa izindawo ezihlanzekile zokubopha
• Indawo evikelayo iqeda njenge-OSP noma i-ENIG - Ivimbela ukuphindaphinda kwe-oxidation ngesikhathi sokugcina
• Izinqubo zokubhaka ngaphambilini ezilawulwayo - Iqeda ukumuncwa komswakama okwenza buthaka izibopho
• Izindawo zokugcina ezingangcoli - Igcina ubuqotho bendawo yethusi

3. Ukulawula Ukucindezeleka Okushisayo ku-Copper Coin PCB

I-coefficient yokungezwani kokwanda okushisayo phakathi kwezinhlamvu zemali zethusi ezishumekiwe nezinto ezizungezile ze-dielectric kudala ingcindezi enkulu yokushisa ngesikhathi sokupholisa i-lamination kanye nokuhamba ngebhayisikili okushisayo okulandelayo. Lezi zingcindezi zibonakala njenge-warpage yebhodi, ukuqhekeka okuhlanganyelwe kwe-solder, nokungahleleki kahle kwengxenye okuphazamisa ikhwalithi yomhlangano.

Amasu asebenzayo okunciphisa ingcindezi:

• Imiklamo yesitaki elinganiselwe enokubekwa kwethusi okulingene - Yehlisa amandla okunweba okuhlukile
• Amaphrofayili wokushisa we-lamination wezinyathelo eziningi - Ilawula amazinga okupholisa ukunciphisa ukwakheka kwengcindezi
• High-Tg resins kanye ne-ceramic-egcwele prepregs - Ifanisa izakhiwo ze-CTE kuzo zonke izendlalelo zezinto

4. Ukunemba Kobukhulu Ekubekweni Kwemali Yethusi

Ukuchezuka kokuma phakathi kwezinhlamvu zemali zethusi nezimbotshana ezigayiwe kubangela ngokuqondile ukwehluleka kokusebenza okushisayo ngokudala izikhala kumzila wokuqhuba ukushisa. Ukufeza ukunemba okudingekayo kudinga ukunemba kwemishini, ukuhlola okuzenzakalelayo, kanye nempendulo yenqubo yesikhathi sangempela ukuze kugcinwe ukubekezelelana kwezikhundla ngaphakathi kwebanga elamukelekayo.

Ukuthuthukiswa Kwenqubo Ye-Copper Coin PCB Fabrication

1. Lamination Ipharamitha Control

Ukwenziwa ngcono kwepharamitha yenqubo kusungula amafasitela okulawula amancane okushisa kwe-lamination, ingcindezi, nesikhathi esibhalansisa ukugeleza okuphelele kwe-resin ngokumelene nengcindezi yezinto ezibonakalayo. Ukulawulwa kweplanarity kwangemva kokushumeka kuqinisekisa ukujiya kwebhodi elifanayo, kuyilapho ukuqinisekiswa kokunemba kokuphinda kubhoboze kuqinisekisa ngezikhundla kunxephezela ukuminyaniswa kwezinto ngesikhathi sokucwala.

2. Ukuqinisekiswa Kwekhwalithi Nokuhlolwa

Ukuhlola okungabhubhisi kusetshenziswa ukuhlolwa kwe-X-ray kanye nokuskena kwe-C-SAM kuthola izikhala ezingaphansi komhlaba kanye ne-delamination engabonakali ekuhlolweni okubonakalayo. Ukuqinisekiswa kokwethenjelwa ngokuhlolwa kokuhamba ngebhayisikili okushisayo nokuhlolwa kokuhamba ngebhayisikili kulinganisa amandla ebhondi yesixhumi esibonakalayo nokuzinza kokusebenza kwesikhathi eside ngaphansi kwezimo zokusebenza, kusungula amamethrikhi ekhwalithi ahlukanisa ukukhiqizwa okwamukelekayo kumayunithi anesici.
