Cov kev sib txuas lus hauv ntiaj teb tau hloov zuj zus rau ib qhotshiabera nyob rau hauv yuav luag 10 xyoo. Lub sijhawm 2 G era tau pib nyob rau hauv 1990 s. 4 G tes hauj lwm tau sawv 2 010. } 020. Kuv yuav tsum hais tias 5 G tes hauj lwm tau los tiag tiag ...
Hauv qee lub nroog, peb tus tswv loj tau pib xa 5 G ntawm qhov loj. Pilot lub nroog xws li Beijing thiab Wuhan tau ua tiav tag nrho ntawm 5 G cheeb tsam hauv nroog 2019. Yuav kom ua tiav 5 G thev naus laus zis, kev siv Circuit Court board yog qhov tseem ceeb. Hauv kev lag luam hluav taws xob, hloov pauv cov kab hluav taws xob tuaj yeem hais tau cov roj ntsha rau cov khoom lag luam hluav taws xob. Tshwj xeeb nyob rau hauv kev sib tw ntawm nyias, me me, hnav, thiab cov khoom siv hluav taws xob ntau, cov hluav taws xob hloov pauv tau muaj qhov zoo ntawm cov xov hluav taws xob siab, lub teeb thiab nyias, hloov tau yooj yim, thiab peb-qhov sib dhos, thiab kev lag luam kev lag luam muaj peev xwmthiab incaav muaj zog.
Tuslosntawm lub sijhawm 5 G era kuj tseem tso cov kev cai siab dua nyob rau R& D, ntau lawm, thiab tswj kev muaj peev xwm ntawm qhov dav dav pawg thawj coj saib kev lag luam. Cov chaw tsim khoom lag luam yuav tsum muab cov khoom lag luam uas tsis muaj nuj nqis rau kev ua lag luam ntawm tus nqi nrawm dua. Txhim kho cov khoom siv tswj kev ua haujlwm taug kev tau dhau los ua qhov tseem ceebfeem.
Txog kev coj ua, cov qauv ib txwm muaj xws li tuag, milling cutter, stamping thiab lwm yam. Tab sis qhov no yog cov neeg siv tshuab hu rau kev sib cais cov txheej txheem sib cais, uas muaj kev ntxhov siab, yooj yim los tsim burrs, plua plav, thiab tsis siab nyob rau hauv qhov tseeb, yog li nws maj mam hloov los ntawm cov txheej txheem laser txiav. Laser siv raws li qhov kev sib txuas ntawm lub tshuab uas tsis siv sib cuag. Tuaj yeem siv qhov kub loj rau lub teeb ua kom muaj zog (650 mW / hli 2) mus rau kev ua kom pom tseeb me me (100-500UM). Lub zog hluav taws xob zoo no tuaj yeem siv rau kev txiav laser, drilling, kos cim, vuam, sau ntawv thiab lwm yam ntaub ntawv ntau yam Kev ua tiav.Laser txiav PCB / FPC tshem tawm qhov xav tau ntawm ob peb cov pwm zoo li kev cai ib txwm, txuag lub sijhawm thiab tus nqi; thiab laser txiav yog tsis sib cuag ua, uas tshem tawm cov kev puas tsuaj rau cov khoom siv thaum lub sij hawm sib tiv tauj xws li cov neeg kho tshuab stamping thiab zoo heev txhim kho qhov tawm ntawm Laser txiav PCB / FPC yog kev tiv thaiv tsis pom ntawm kev txhim kho.
Zoo ntawm laser txiav yooj ywm Circuit Court laug cam
1. Raws li txoj kab kev ntom ntom ntom ntaws thiab lub suab ntawm FPC cov khoom lag luam txuas ntxiv, thiab cov FPC teeb duab kab sib txawv tau dhau los ua ntau dua, qhov no ua rau nws nyuaj thiab nyuaj los ua FPC pwm. Laser txiav ntawm cov chaw hloov pauv tau siv NC kev ua haujlwm, tshem tawm qhov xav tau cov txheej txheem pwm, Txuag cov nqi ntawm qhib pwm;
2. Vim lub shortcomings ntawm mechanical ua thiab txwv tsis pub ua cov raug, laser txiav yooj ywm Circuit Court board siv high-kev ua haujlwm ultraviolet laser lub teeb qhov chaw nrog zoo nqaj zoo. Zoo txiav nyhuv.
3. Vim tias txoj kev siv tshuab ib txwm yog ib txoj kev sib cuag machining. Ua kev ntxhov siab yuav zam rau FPC, uas tuaj yeem tsim kev puas tsuaj rau lub cev. Laser txiav ntawm cov hluav taws xob hloov tau yooj yim yog tsis sib cuag, uas ua tau zoo zam kev puas tsuaj thiab deformation ntawm kev ua cov khoom siv.Nrog txoj kev loj hlob ntawm cov thev naus laus zis thev naus laus zis, ntau yam khoom siv hluav taws xob tau yug los. Daim ntawv thov ntawm cov khoom siv hluav taws xob hloov yooj yim yuav tsav cov laj thawj laj luam lab, pab cov kev lag luam ib txwm muaj peev xwm nce cov nqi tsim khoom, thiab coj cov hloov pauv hloov pauv rau kev lag luam qauv thiab tib neeg lub neej.
