Ngaba uyazi ukuba zeziphi iingenelo ze-Multilayer PCB?

Kubomi bemihla ngemihla, ibhodi yesekethe ye-multi-layer PCB okwangoku lolona hlobo lwebhodi yesekethe lusetyenziswa kakhulu. Ngomlinganiselo obalulekileyo onjalo, kufuneka uzuze kwiinzuzo ezininzi zebhodi yesekethe ye-PCB enemigangatho emininzi. Makhe sijonge iingenelo.

 

Iingenelo zesicelo seebhodi zesekethe zePCB ezinamanqwanqwa amaninzi:1. Uxinaniso oluphezulu lwendibano, ubungakanani obuncinci, ubunzima obulula, ukuhlangabezana neemfuno zokukhanya kunye ne-miniaturization yezixhobo zombane;2. Ngenxa yoxinano oluphezulu, i-wiring phakathi kwamacandelo (kubandakanywa amacandelo) iyancitshiswa, ukufakela kulula, kwaye ukuthembeka kuphezulu;3. Ngenxa yokuphindaphinda kunye nokuhambelana kwemizobo, inciphisa iingcingo kunye neempazamo zendibano kwaye igcina ukugcinwa kwezixhobo, ukulungisa iimpazamo kunye nexesha lokuhlola;4. Inani lee-wiring layers linganyuswa, ngaloo ndlela likhulise ukuguquguquka koyilo;

5. Inokwenza isekethe ene-impedance ethile, enokuthi yenze i-high-speed transmission circuit;

6. Isekethe, umaleko okhuselayo wesekethe yamagnetic unokusetwa, kwaye umaleko wokulahla ubushushu obungundoqo wesinyithi nawo unokusetwa ukuhlangabezana neemfuno zemisebenzi ekhethekileyo efana nokukhusela kunye nokushisa ubushushu.

Ngophuhliso oluqhubekayo lwetekhnoloji yombane kunye nokuphuculwa okuqhubekayo kweemfuno zezixhobo zombane kwikhompyuter, ezonyango, ezomoya kunye namanye amashishini, ibhodi yesekethe iphuhlisa kwicala lokunciphisa umthamo, ukunciphisa umgangatho kunye nokwanda koxinzelelo. Ngenxa yokucuthwa kwendawo ekhoyo, iibhodi eziprintiweyo ezinecala elinye kunye namacala amabini azikwazi ukuphumeza ukwanda koxinzelelo lwendibano. Ngoko ke, kuyimfuneko ukuqwalasela ukusetyenziswa kweebhodi zeesekethe ze-multilayer ezinenani eliphezulu leengqimba kunye noxinzelelo oluphezulu lwendibano. Iibhodi zeesekethe ze-Multilayer zisetyenziswe ngokubanzi ekwenzeni iimveliso ze-elektroniki ngenxa yoyilo lwazo oluguquguqukayo, umbane ozinzileyo kunye nothembekileyo kunye nokusebenza koqoqosho oluphezulu.
