Chii chinonzi single-sided double-sided multi-layer board?
Mabhodhi ePCB anorongedzerwa zvichienderana nenhamba yezvikamu zvedunhu: single-sided, double-sided and multi-layer boards.Mabhodhi akajairwa akawanda-akaturikidzana anowanzo 4-layer board kana 6-layer board, uye akaomarara akawanda-layer board anogona kusvika anopfuura gumi nemaviri.Iine marudzi matatu anotevera ekukamuranisa:
Single panel: Pane yakanyanya kukosha PCB, zvikamu zvakanangidzirwa kune rimwe divi, uye waya dzakanangidzirwa kune rimwe divi.Nekuti waya dzinongoonekwa kune rimwe divi, rudzi urwu rwePCB rwunodaidzwa kuti rimwe divi (Single-sided).Nemhaka yokuti bhodhi rimwe-side rine zvirambidzo zvakawanda zvakasimba pakugadzirwa kwedunhu (nokuti kune rutivi rumwe chete, wiring haigoni kuyambuka uye inofanira kunge iri nzira yakasiyana), saka matunhu ekutanga chete anoshandisa rudzi urwu rwebhodhi.
Bhodhi remativi maviri: Rudzi urwu rwebhodhi redunhu rine waya kumativi ese, asi kushandisa waya dzine mativi maviri, panofanirwa kuve nekubatana kwedunhu kwakakodzera pakati pemativi maviri.Iwo "mabhiriji" pakati pemasekete akadaro anonzi vias.A via igomba diki rakazadzwa kana kuvharwa nesimbi paPCB, inogona kubatanidzwa newaya kumativi ese.Nekuti nzvimbo yebhodhi rine mativi maviri yakakura zvakapetwa kaviri kupfuura yebhodhi-rimwe divi, uye nekuti wiring inogona kupindirana (inogona kukuvadzwa kune rimwe divi), inonyanya kukodzera kushandiswa mumaseketi. izvo zvakaoma kupfuura bhodhi redivi rimwe chete.
Multilayer board: Kuti uwedzere nzvimbo inogona kuve newaya, iyo multilayer board inoshandisa mamwe ma single kana maviri-sided wiring board.Shandisa imwe yakapetwa kaviri semukati wemukati, maviri-akabatana seyekunze dhizaini kana maviri-aviri mativi seyemukati layer uye maviri akasarudzika sechikamu chekunze chebhodhi redunhu rakadhindwa.The Positioning hurongwa uye insulating bonding zvinhu alternately pamwe uye conductive pateni Printed redunhu mapuranga ari interconnected maererano magadzirirwo zvinodiwa kuva mana-layer kana matanhatu-layer akadhindwa redunhu mapuranga, anonziwo multilayer akadhindwa redunhu mapuranga.Huwandu hwezvikamu zvebhodhi zvinoreva kuti kune akati wandei akazvimirira wiring layer.Kazhinji nhamba yezvikamu zvakaenzana uye ine maviri ekunze ekunze.Mazhinji mamaboards ane 4 kusvika 8 akaturikidzana echimiro, asi zvehunyanzvi, mabhodhi ePCB ane angangoita zana akaturikidzana anogona kuwanikwa mudzidziso.Mazhinji makuru makuru emakomputa anoshandisa zvakaringana-akawanda-layer mamaboards, asi nekuti rudzi urwu rwekombuta runogona kutotsiviwa neboka remakomputa mazhinji akajairwa, mabhodhi e-super-multilayer haasi kushandiswa zvishoma nezvishoma.
Nekuti iwo maseru muPCB akanyatsobatanidzwa, kazhinji hazvisi nyore kuona iyo chaiyo nhamba, asi kana iwe ukanyatsotarisisa pabhodhi reamai, unogona kuiona.
Zvinoenderana neyakapfava uye yakaoma kupatsanura: yakakamurwa kuita akajairwa edunhu mabhodhi uye anochinjika edunhu mabhodhi.Iyo mbishi yePCB ndeye copper clad laminate, inova iyo substrate zvinhu zvekugadzira akadhindwa edunhu mabhodhi.Inoshandiswa kutsigira zvikamu zvakasiyana-siyana, uye inogona kuwana magetsi ekubatanidza kana magetsi ekudzivirira pakati pavo.Zvichitaurwa zviri nyore, PCB ibhodhi rakatetepa rine maseketi akabatanidzwa uye zvimwe zvinhu zvemagetsi.Ichaonekwa munenge mumidziyo yese yemagetsi.
