Nrog kev nce nrov ntawm cov xov tooj smartphones, cov tshuaj tiv thaiv tshuaj ntsuam tau dhau los ua cov khoom siv tseem ceeb rau cov neeg siv niaj hnub. Txawm li cas los xij, qhov zoo ntawm cov tshuaj tiv thaiv kev lag luam ntawm kev ua lag luam sib txawv, ua rau kev txhim kho kev sib koom ua ke ntawm cov qauv kev coj ua tseem ceeb heev rau kev tiv thaiv cov neeg siv khoom txoj cai thiab tswj kev lag luam kev loj hlob.
Tam sim no, cov qauv kev siv rau cov xov tooj ntawm tes screen tiv thaiv feem ntau yog hais txog lub teb chaws lossis kev lag luam- cov lus qhia tshwj xeeb, xws li cov qauv ntsuas cov khoom xws li GB/T 2918-2018, "Standard Environment for Conditioning and Testing of Plastic Specimens," as well as product standard developed by some company. Thoob ntiaj teb, ISO (International Organization for Standardization) thiab ASTM (American Society for Testing and Materials) kuj muab cov kev ntsuam xyuas cuam tshuam rau cov cim tseem ceeb xws li kev puas tsuaj, kev sib kis, thiab kev cuam tshuam.
Hais txog cov ntsiab lus tseem ceeb, siab -cov tshuaj tiv thaiv zoo yuav tsum ua raws li cov cai hauv qab no:
1. Lub teeb xa hluav taws xob: Feem ntau, tus nqi ntau dua lossis sib npaug li 90% yuav tsum tau ua kom pom tseeb yam tsis muaj kev cuam tshuam txog kev pom.
2. Kev tiv thaiv kev puas tsuaj: Siv cov tshuaj txhuam los yog cov ntawv xuab zeb rub, lub siab -cov tshuaj tiv thaiv zoo yuav tsum tiv taus tsawg kawg yog 500 rubs yam tsis muaj khawb.
3. Impact Resistance: Cov kev ntsuam xyuas ua los ntawm steel pob poob los yog hardness kuaj xyuas kom cov zaj duab xis muaj peev xwm nqus tau sab nraud quab yuam, txo qhov kev pheej hmoo ntawm kev tshuaj ntsuam breakage.
4. Haum: Cov yeeb yaj kiab tiv thaiv yuav tsum ua kom nruj rau ntawm lub vijtsam, tsis muaj npuas lossis cov npoo dawb, kom tsis txhob cuam tshuam rau kev kov rhiab heev.
Qhov tsis muaj cov qauv kev lag luam tseem yog qhov teeb meem tseem ceeb. Tam sim no, Tuam Tshoj tseem tsis tau tshaj tawm cov qauv hauv tebchaws uas yuav tsum tau ua, ua rau muaj kev nkag mus rau cov nqi qis - nqi, qis - cov yeeb yaj kiab zoo rau hauv khw. Cov yeeb yaj kiab no nthuav tawm cov teeb meem xws li warping, yellowing, thiab tsis khawb tsis kam. Qee cov tuam txhab siv IPC-4552 (cov qauv txheej txheem hluav taws xob) lossis tsim lawv tus kheej cov qauv, tab sis qhov no tsis muaj kev saib xyuas kev sib koom ua ke.
Raws li cov neeg siv khoom xav tau kev tshuaj ntsuam xyuas kev ua tau zoo nce ntxiv, kev lag luam yuav tsum tau tsim kom muaj cov txheej txheem ua tiav ntau dua, suav nrog cov cim qhia tshwj xeeb xws li lub teeb xa hluav taws xob, lub teeb xiav, thiab cov ntiv tes tiv thaiv, thiab ntxiv dag zog rau kev saib xyuas kev lag luam kom paub meej cov khoom zoo raws li kev nyab xeeb thiab cov neeg siv khoom. Cov neeg siv khoom yuav tsum tau ua tib zoo saib xyuas cov qauv kev coj ua uas tau teev tseg rau ntawm cov khoom lag luam thiab ua ntej cov khoom lag luam uas ua tau raws li qhov yuav tsum tau ua.
