LCM cov qauv tshuaj xyuas cov khoom thiab cov txheej txheem tshuaj xyuas
1. LCM cov qauv tshuaj xyuas cov khoom: (1) Kev soj ntsuam xyuas:
1 Cov xwm txheej ib puag ncig yuav tsum tau teeb tsa raws li (qhov kub li qub) 20 ~ 25 ℃, (hauv qhov kub li qub) 65% ± 5% RH (humidity).
②Cov cuab yeej rau kev ntsuas lub teeb pom kev zoo yog lub teeb 20W fluorescent, uas yog 50cm saum toj ntawm qhov chaw ua haujlwm (khoom) thiab pom qhov muag pom nyob rau hauv cov xwm txheej uas qhov pom kev deb yog ntau tshaj 30cm.
(2) Kev soj ntsuam cov qauv:
Kev tshuaj xyuas yog feem ntau raws li batch sampling, thiab cov qauv qauv yog raws li GB2828-93. 2. Qee cov lus siv feem ntau hauv LCM tshuaj xyuas:
(1) Dub dots, kab dub
Nws qhia tau hais tias tsaus me ntsis thiab cov kab tsaus nti thaum lub hwj chim qhib, thiab cov kua siv lead ua kua hluav taws xob tsis hloov pauv thaum nws hloov pauv. ②Nws qhia tau hais tias tsaus nti linear me ntsis thaum nws yog powered rau, thiab cov kua siv lead ua tsav voltage hloov heev thaum nws hloov.
(2) Cov pob dawb
Lub teeb xim xim tau tshwm sim thaum siv fais fab, thiab tsis muaj qhov hloov pauv loj thaum cov kua siv lead ua hluav taws xob hloov pauv hloov. ②Nws qhia txog lub teeb xim xim thaum siv fais fab, thiab kev hloov loj tshwm sim thaum cov kua siv lead ua hluav taws xob hloov pauv. (3) kab dawb
① Lub teeb-xim linear me ntsis tau tshwm sim thaum siv hluav taws xob, thiab cov kua siv lead ua kua hluav taws xob tsis hloov pauv thaum lub zog tsav tsheb hloov. ②Nws qhia lub teeb-xim linear me ntsis thaum lub zog siv, thiab cov kev hloov loj tshwm sim thaum cov kua siv lead ua kua hluav taws xob hloov pauv. (4) Blue dot
Nws pom cov pob tsaus nti heev thaum siv fais fab, thiab cov kev hloov loj tshwm sim thaum cov kua siv lead ua kua hloov pauv. (5) Kab ntsug (kab ntsug) tsis zoo
Thaum lub hwj chim qhib, txoj kab ntev (feem ntau yog luv axis) tsis ci thiab maj mam tso tawm. (6) Kab rov tav kab tsis xws luag
Thaum lub hwj chim qhib, kab rov tav (feem ntau yog txoj kab ntev) tsis ci thiab ntiav. (7) Hla kab defect
Thaum lub hwj chim qhib, qhov kev sib tshuam ntawm kab rov tav thiab ntsug tsis teeb. 3. Kev soj ntsuam xyuas;
(1) Kev kuaj pom dav dav:
Txhua qhov loj me ntawm LCM (txhua lub cuab yeej).
② Cov tsos ntawm lub polarizer ntawm LCM LCD thiab xim uniformity ntawm lub vijtsam. Cov tsos ntawm polarizer muaj xws li: khawb, indentations, npuas thiab av. ③Flux, solder pob qij txha tsis tuaj yeem soldering, cuav soldering, tsis txaus solder, bridging, overflow (khoom siv ntau dhau).
Cov tsos ntawm LCM plhaub, seb cov xim electroplating yog txawm, txawm tias muaj khawb, tev xim.
⑤ Lub uniformity ntawm cov hlau lead ntawm cov khoom yog tsw thiab khawb.
Lub npog ntsej muag ntawm lub rooj tsavxwm PCB yog scented (muaj qhov txwv loj), thiab seb cov ntawv ci tooj liab puas raug khawb. ⑦ Lub degree ntawm ntsia hlau fastening thiab plhaub ko taw fastening.
(2) Fais fab-on zaub check:
Input voltage, kev khiav hauj lwm zaus, tam sim no noj, LCD sib piv thiab teb ceev.
Thaum energized (raws li tus qauv input voltage), saib lub kaum sab xis ntau, seb cov duab cov duab muaj cov saum toj no-hais tsis xws luag thiab graphics misalignment. 4. LCM sampling ib puag ncig kuaj:
Ua ntej LCM tawm ntawm lub Hoobkas, ntau yam kev ntsuam xyuas ib puag ncig yuav tsum tau coj mus kuaj. Cov khoom muaj xws li: high-temperature power-on, high-temperature (40°C, 60°C) placement test.
② Fais fab ntawm qhov hluav taws xob tsis tshua muaj hluav taws xob thiab tso qhov ntsuas kub tsawg (0C lossis -20 ° C). ③ Kub thiab av noo, lub zog rau thiab khaws cia.
Kev vibration test.
Qhov ntsuas kub thiab ntsuas saum toj no raug tswj nyob rau hauv ib lub sijhawm.
