Ua ib feem ntawm cov khoom tseem ceeb tshaj plaws hauv kev lag luam hauv kev ua lag luam, PCB pawg thawj coj siv rau tag nrho cov khoom hluav taws xob thiab hu ua "leej niam cov khoom hluav taws xob". Nrog rau cov kev cai kom zoo ntawm PCB cov laug, thiaj li paub zoo txog kev tswj xyuas thiab kev tswj cov khoom siv hauv kev tsim, cov kev sib txuas hauv kev khiav lag luam xws li cov cim npav, qhov chaw pov npav thiab QR cov cai ntawm PCB boards.
Thaum tam sim no, PCB npav ua tau mas muaj ob txoj kev: lo lo ntxhuav screen printing thiab laser npav.
Cov kab xev tsom iav siv cov txuj ci zoo ua kom xa tawm cov cim ua cim los ntawm ib qho ntawm lub ntsej muag ntawm lub vijtsam thiab txia ntawm lub vha ntawm lub nkoj ntawm sab nraud. Qhov seem ntawm lub mesh ntawm qhov screen yuav muab thaiv, tsis yog los ntawm cov cwj mem, tsuas yog seem ntawm qhov saum npoo ntawm pawg thawj coj, tus cwj mem raws hauv cov pa tawm yuav tsim cov ntawv, logo, qauv thiab lwm yam. Hom kev lag luam no yog pheej yig thiab kev ua haujlwm ceev yog ceev, tab sis muaj kev ua tsis tau zoo xws li ntxim nyiam, ua kom yooj yim poob lub logo, kos tsis tau lub PCB lub rooj tsav tsheb nrog lub vev xaib me me, thiab tej yam tshuaj toxicity ntawm cov tshuaj raw khoom .
Laser npav siv laser high-power-lens rau zos pom lub PCB, ua rau cov khoom siv deg siv los ua kom tawg, tawm hauv cov cim ruaj khov. Cov khoom siv uas tsis yog hu ua cov cim tsis tshua muaj ob sab hauv cov qhov web site me me, ua kom siab tau zoo thaum tsis muaj teeb meem tsis hnav thiab tsim kua muag vim lub siab thiab tsis kub, acid thiab alkali hloov thiab sab nrauv kev sib txhuam. Tsis muaj kev pabcuam tshuaj lom neeg, thiab tsis muaj qhov cuam tshuam rau cov neeg ua haujlwm tsis muaj teeb meem thiab chaw nyob.
Lub laser marking tshuab rau PCBs muaj peev xwm compensate rau lub shortcomings ntawm silk screen ua nrog nws precision thiab ua yooj yim, zoo heev txhim kho cov khoom tsim thiab tawm los, txo nqi thiab txo pa phem. Laser npav yog qhov ua tau zoo tshaj rau kev kos npe rau PCBs, thiab tau siv ntau qhov chaw xws li cov khoom digital, cov khoom siv looj ntsej muag, thiab cov tsheb nqaj hlau tsheb.
