Tsanangudzo yebhodhi redunhu rakadhindwa uye kupatsanurwa kwayo

Mabhodhi edunhu akadhindwa, anozivikanwawo semapuranga edunhu akadhindwa, ndivo vanopa magetsi ekubatanidza zvinhu zvemagetsi.
Iyo yakadhindwa yedunhu bhodhi inonyanya kumiririrwa ne "PCB", asi haigone kunzi "PCB board".
Magadzirirwo emapuranga edunhu akadhindwa anonyanya kugadzira marongerwo;chakanakira kushandisa matunhu mapuranga ndiko kuderedza zvikuru wiring uye gungano kukanganisa, uye kunatsiridza otomatiki pamwero uye kugadzirwa basa mwero.
Mapuranga edunhu akadhindwa anogona kukamurwa kuita rimwe-sided, kaviri-side, mana-layer, matanhatu-layer uye mamwe akawanda-layer edunhu mabhodhi zvichienderana nenhamba yemabhodhi edunhu.
Sezvo iyo yakadhindwa yedunhu bhodhi isiri yakajairika yekupedzisira chigadzirwa, tsananguro yezita iri kuvhiringa zvishoma.Semuenzaniso, iyo mamaboard yemakomputa ega inodaidzwa kuti mamaboard, asi kwete zvakananga kunzi bhodhi redunhu.Kunyangwe paine mabhodhi edunhu mubhodhi reamai, asi Iwo haana kufanana, saka izvo zviviri zvine hukama asi hazvigone kunzi zvakafanana kana uchiongorora indasitiri.Mumwe muenzaniso: nokuti kune zvikamu zvedunhu zvakabatanidzwa zvakatakurwa pabhodhi redunhu, nhau dzenhau dzinoitumidza IC board, asi chaizvoizvo haina kufanana nebhodhi redunhu rakadhindwa.Kana tichiwanzotaura nezvebhodhi redunhu rakadhindwa, tinoreva bhodhi risina chinhu - kureva, bhodhi redunhu risina zvikamu pairi.

Kurongwa kwemapuranga edunhu akadhindwa

single panel
PaPCB inonyanya kukosha, 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).Nokuti mapuranga ane divi rimwe chete ane zvipingamupinyi zvakawanda pakugadzira wiring (nekuti kune divi rimwe chete, wiring haigoni kuyambuka uye inofanira kutenderera nenzira dzakasiyana), matunhu ekutanga chete akashandisa rudzi urwu rwebhodhi.

Double panel
Iri bhodhi redunhu rine wiring kumativi ose, asi kushandisa mativi ose ewaya, panofanira kuva nekubatana kwakakodzera kwedunhu pakati pemativi maviri."Mabhiriji" akadaro pakati pematunhu anonzi vias.Vias maburi madiki paPCB, akazadzwa kana kupendwa nesimbi, anogona kubatanidzwa newaya mativi ese.Nekuda kwekuti nzvimbo yebhodhi rine mativi maviri yakakura zvakapetwa kaviri kupfuura yebhodhi-rimwe divi, bhodhi rine mativi maviri rinogadzirisa kunetsa kwekusiya waya mubhodhi-rimwe divi (rinogona kupfuudzwa kune rimwe divi. side kuburikidza neburi), uye inonyanya kukodzera kushandiswa mumaseketi akaoma kunzwisisa kupfuura bhodhi rine divi rimwe chete.

Multilayer board
Kuti uwedzere nzvimbo iyo inogona kuve newaya, mamwe mabhodhi ewaya ega kana maviri-maviri anoshandiswa kune akawanda mabhodhi.Bhodhi redunhu rakadhindwa rine mativi maviri emukati layer, maviri ane divi rimwe divi rekunze akaturikidzana, kana maviri ane mativi maviri emukati akaturikidzana uye maviri ega-sided ekunze akaturikidzana, anochinjika pamwe chete neanomira system uye insulating bonding zvinhu, uye conductive mapatani.Mabhodhi edunhu akadhindwa akabatana maererano nezvinodiwa zvekugadzira anova mana-layer uye matanhatu-layer akadhindwa edunhu mabhodhi, anozivikanwawo seakawanda-layer akadhindwa edunhu mabhodhi.Huwandu hwezvikamu zvebhodhi hazvireve kuti kune akati wandei akazvimirira wiring layer.Muzviitiko zvakakosha, chigadziko chisina chinhu chichawedzerwa kudzora kukora kwebhodhi.Kazhinji, huwandu hwezvikamu hwakaenzana uye hunosanganisira ekunze maviri akaturikidzana.Mazhinji mamaboards ane 4 kusvika 8 akaturikidzana echimiro, asi nehunyanzvi anogona kuwana angangoita zana maseru ePCB.Mazhinji makuru makuru emakomputa anoshandisa zvakaringana-akawanda-layer mamaboards, asi nekuda kwekuti makomputa akadaro anogona kutsiviwa nemasumbu emakomputa mazhinji akajairwa, e-ultra-multi-layer board akadonha zvishoma nezvishoma kusashanda.Nekuti iwo akaturikidzana muPCB akanyatsobatanidzwa, kazhinji hazvisi nyore kuona iyo chaiyo nhamba, asi kana ukanyatsotarisisa pabhodhi reamai, unogona kuiona.
