Tsananguro Yekuedza

chinangwa

Ita shuwa kuti zvigadzirwa zvekambani zvinosangana nezvinodiwa nevatengi, zvinopa hwaro hwekuongorora chigadzirwa, uye kuona mhando yechigadzirwa.

Makuriro ekushandisa

Ichi chiyero chinoshanda kune ese TFT module zvigadzirwa zvinogadzirwa neXX.

Kuedza Zvishandiso

Magetsi kuyera muchina, bvunzo fixture, kukudza girazi, fluorescent mwenje, vernier caliper

Sampling chirongwa uye tarisa mamiriro ezvakatipoteredza

Iyo yekugadzira yuniti (kana maitiro QC) inoita yakazara kuongorora kwechitarisiko kuongorora uye magetsi kuita bvunzo, uye nehukuru chiyero kana yakakosha kuongorora, chidimbu chekutanga chemhando yega yega chakatemwa uye kuyedzwa 5pcs.

Iyo yemhando yuniti inoyera 5pcs yemuenzaniso wekutanga weimwe modhi, uye inotora iyo GB / -2012 yakajairwa kuongorora imwe-nguva sampling chirongwa chechitarisiko chekutarisa, uye yakajairika yekuyera chikamu chiri II.

Chikamu chisina kukodzera Chikamu chinotenderwa (AQL) Anokodzera mhando yakajairwa kuongororwa
Kushayikwa kukuru   Kana saizi isina kukwana, 0 gamuchira 1 kudzoka
Kuzviisa pasi  
zvachose

Muongorori anoda kupfeka rin'i ye electrostatic uye machira masere eminwe pamaoko ese maviri.Kana iri LCD isina polarizer yakasungirirwa, zvigunwe zvese zvinofanirwa kupfeka machira emunwe.

Muongorori anogona kutarisa kana kuenzanisa nefafura yekufananidza tafura.

Ndokumbira utarise kune iyo sampuli yeiyo bvunzo yemagetsi uchishandisa bvunzo fixture uye kuratidza skrini.

Iyo nhambwe iri pakati pemeso emuongorori uye chigadzirwa chiri 30 ~ 40 cm. Yekutarisa yekutarisa kona ndeye ± 15 madhigirii kumberi kwenzvimbo yakatwasuka yekuratidzira pani uye ± 45 madhigirii kumberi kwepamusoro peiyo yakatwasuka kuratidza pani (ona mufananidzo uri pazasi)

Zvigadzirwa zvemwenje: 800 ~ 1200LUX yekutarisa kunoonekwa

Nharaunda tembiricha: 25 ± 5 ℃

Tarisa chinhu

(1) Tsananguro yezvikanganiso poindi zvinokonzerwa nemapaneru emukati.

a) Mavara akajeka: akajeka, akaenzana-akaenzana matinji anoonekwa paLCD pasi peiyo nhema pateni.

b) Dots madema: Mune yakachena tsvuku, girini, uye bhuruu mifananidzo, matema madhiza ane akafanana saizi anoonekwa paLCD.

c) 2 points iri pedyo = 1 peya = 2 mapoinzi.
