Multi-layer PCBmukukurukurirana, zvekurapa, kudzora maindasitiri, chengetedzo, mota, magetsi, ndege, mauto, komputa peripheral uye mamwe minda se "core simba", mabasa echigadzirwa anowedzera uye akawedzera, mitsara yakawanda uye yakaoma, saka zvishoma, kuoma kwekugadzira. yakawedzerawo.
Parizvino, thePCB vagadziriiyo inogona batch kugadzira multilayer redunhu mabhodhi muChina kazhinji anobva kumabhizinesi ekunze, uye mashoma emabhizinesi epamba ane simba rebatch.Multi-layer redunhu bhodhi kugadzirwa hakungodi yakakwira tekinoroji nekudyara kwemidziyo, yakawanda inoda ruzivo rwekugadzira uye vashandi vehunyanzvi, panguva imwe chete, tora akawanda-layer board mutengi chitupa, akasimba uye anonetesa maitiro, saka, akawanda-layer redunhu bhodhi rekupinda chikumbaridzo. yakakwira, kuzadziswa kwekugadzirwa kwemaindasitiri kwakareba.Kunyanya, matambudziko ekugadzirisa akasangana mukugadzira multilayer redunhu board ndiwo anotevera mana anotevera.Multilayer redunhu bhodhi mukugadzira uye kugadzirisa matambudziko mana.
1. Kuoma mukugadzira mutsara wemukati
Kune akasiyana akakosha anodikanwa ekumhanya kwazvo, gobvu mhangura, yakakwira frequency uye yakakwira Tg kukosha kune multilayer board mitsara.Izvo zvinodikanwa zvemukati wiring uye graphic size control zviri kuramba zvichikwira nekukwira.Semuyenzaniso, iyo ARM yekuvandudza bhodhi ine yakawanda impedance siginecha mitsara mune yemukati layer, saka zvinonetsa kuve nechokwadi chekuvimbika kwe impedance mukugadzirwa kwemukati mutsara.
Kune mitsetse yakawanda yezviratidzo muchikamu chemukati, uye hupamhi uye nzvimbo yemitsara inenge 4mil kana pasi.Iyo yakatetepa kugadzirwa kweakawanda-musimboti ndiro iri nyore kuunyana, uye izvi zvinhu zvichawedzera mutengo wekugadzira weiyo yemukati layer.
2. Kuomerwa mukukurukurirana pakati pezvikamu zvemukati
Iine akawanda uye akawanda akaturikidzana e-multilayer plate, zvinodiwa zvemukati wemukati zvakakwirira uye zvakakwirira.Iyo firimu ichawedzera uye ichiderera pasi pesimba re ambient tembiricha uye humidity muwekishopu, uye core plate ichava nekuwedzera kwakafanana uye kuderera kana yagadzirwa, izvo zvinoita kuti kurongeka kwemukati kuome kudzora.
3. Matambudziko mukutsikirira
Iyo yepamusoro yeakawanda-sheet core plate uye PP (semi-solidified sheet) inotarisana nezvinetso zvakaita sekuisa, kutsvedza uye zvigubhu zvakasara kana uchidzvanya.Nekuda kwehuwandu hukuru hwezvikamu, iyo yekuwedzera uye shrinkage control uye saizi coefficient muripo haigone kuramba ichienderana.Iyo yakaonda insulation pakati pematanho inotungamira nyore mukukundikana kwekuvimbika bvunzo pakati pematanho.
4. Matambudziko mukugadzirwa kwekuchera
Iyo yakawanda-layer plate inotora yakakwirira Tg kana imwe yakakosha ndiro, uye kushata kwekuchera kwakasiyana nezvinhu zvakasiyana, izvo zvinowedzera kuoma kwekubvisa glue slag mugomba.Yakakwira density yakawanda-layer PCB ine yakakwira gomba density, yakaderera kugadzirwa kwekuita, nyore kutyora banga, network yakasiyana kuburikidza negomba, mupendero wegomba uri padyo zvakanyanya unotungamira kuCAF mhedzisiro.
Naizvozvo, kuitira kuti uve nechokwadi chekuvimbika kwepamusoro kwechigadzirwa chekupedzisira, zvinodikanwa kuti mugadziri aite zvinoenderana nekutonga mukugadzira.
