Cov Chawj Tsoomfab PCB rau Kev Tsim Tshiab Khoom Siv Hluav taws xob

PCB milling machines yog qhov chaw pab tshaj tshwv CNC tsim nyog rau kev tsim kho tshiab thiab tsim khoom ntau yam tsawg rau printed circuit boards (PCBs). Txawv npaum li kev siv cheem koob los txiav, cov cuab yeej no siv txoj kev txiav me me los tsim cov duab ntawm copper-clad board. Qhov kev ua no siv cov end mills me me (routing bits) los cia cov copper uas tsis xav tau, vim li ntawd tshaj tshwv cov hlua tshwj xeeb. Cov cuab yeej no muaj kev ntsuas zoo txaus siab, feem ntau tuaj yeem tsim cov traces thiab spaces txog ob peb mils (thousandths of an inch), uas yog qhov tseem ceeb rau electronics tshiab ntau zauv. Lawv feem ntau muaj daim ciav sib txuas khaws kom meej kom ntseeg tias kheej tsho tau zoo thiab tsawg vibration. Qhov tseem ceeb tshaj plaws yog qhov vacuum table loss yog lwm hom kev khaws ib qho PCB substrate me me kom raug rau thaum ua haujlwm. Kawm txiav copper layer, PCB milling machines kuj tuaj yeem kho cov through-holes thiab vias, thiab tshuab kawm ib qho chaw ntim mus rau hauv qhov chaw loj dua. Ib co qhov siv ntau dua muaj automatic tool changers los hloov ncig ntawm cov drills thiab routing bits sib txawv tsis tas tswv yim. Txawm tsis ntev npaum li kev siv etching rau kev tsim khoom ntau heev, PCB milling muaj qhov phiaj xwm loj rau kev xam kho, kev tsim kho tshiab, thiab kev tsim khoom tsawg heev, vim nws tso tsis tau chemicals, masks, thiab film, txhawj xeeb rau kev rov qab los ntawm kev tsim kho mus rau functional board.
