Smartphones tau dhau los ua ib feem tseem ceeb ntawm peb lub neej, thiab ib qho ntawm cov khoom tseem ceeb yog lub rooj tsav xwm PCB. PCB (Printed Circuit Board) yog lub cev txhawb nqa tshuab rau cov khoom siv hluav taws xob ua raws li cov tshuab luam ntawv hluav taws xob. Nws muaj kev ua haujlwm ntawm kev sib txuas thiab txhawb nqa cov khoom siv hluav taws xob, nrog rau kev muab lub zog thiab cov teeb liab xa mus rau cov khoom siv hluav taws xob. Yog li, dab tsi yog cov txheej txheem tsim khoom rau PCB circuit boards hauv smartphones?
Ua ntej, kev tsim khoom ntawm PCB circuit boards rau smartphones feem ntau muaj ob peb kauj ruam tseem ceeb: tsim, molding, phaj ua, luam ntawv, sib dhos, thiab kev sim.
Cov theem tsim yog thawj kauj ruam hauv tag nrho cov txheej txheem tsim khoom PCB. Cov neeg tsim qauv siv cov software tsim kev tshaj lij los hloov cov duab kos rau hauv PCB tsim, thiab txiav txim siab tsis xws li qhov loj, tus naj npawb ntawm cov khaubncaws sab nraud povtseg, thiab pad hom ntawm lub rooj tsavxwm. Thaum lub sij hawm tsim qauv, nws yog ib qho tsim nyog yuav tsum xav txog tag nrho cov kev siv hluav taws xob ntawm Circuit Court EMI / EMC kev ua tau zoo, kev tiv thaiv zoo li qub thiab lwm yam kom ntseeg tau tias kev ruaj ntseg thiab kev ntseeg siab ntawm lub rooj tsav xwm Circuit Court.
Cov txheej txheem tsim yog cov txheej txheem ntawm kev hloov cov duab kos duab PCB rau hauv cov khoom siv hluav taws xob tiag tiag. Cov khoom siv molding muaj xws li iav fiber ntau, polyimide, thiab lwm yam. Nyob rau hauv cov txheej txheem molding, lub substrate yog thawj zaug raws li PCB tsim daim duab, thiab tom qab ntawd ib tug series ntawm cov txheej txheem xws li tshuaj etching, copper txheej, drilling, thiab lwm yam. Thaum kawg tau txais ib lub rooj tsav xwm PCB nrog cov kev txiav txim ua ntej thiab qhov apertures.
