Masiku ano, pafupifupi aliyense ali ndi foni yamakono. Ndipo foni iliyonse yanzeru iyenera kubwera ndi SIM khadi. Ndiye SIM khadi ndi chiyani? SIM khadi imadziwika kuti gawo la olembetsa. Imagwira ntchito yofunika kwambiri pama foni am'manja a GSM digito. Ndi gawo lofunikira la foni yanzeru komanso chiphaso cha munthu aliyense wogwiritsa ntchito foni ya GSM.
Pamene mafoni anzeru akuchulukirachulukira, msika wa SIM khadi ukukula mwachangu. SIM khadi ndi chip khadi yomwe ili ndi microprocessor mkati. Ili ndi ma module 5: CPU, RAM, ROM, EPROM kapena EEPROM ndi gawo lolumikizirana. Module iliyonse ili ndi ntchito yake.
Mu SIM khadi yaying'ono ngati iyi, muwona kuti pali ma barcode ndi serial number ya chip. Njira yachikale yowasindikiza pa SIM khadi ndikugwiritsa ntchito inkjet printing. Koma zizindikiro zosindikizidwa ndi inkjet kusindikiza n'zosavuta kufufutidwa. Ma barcode ndi serial nambala zikachotsedwa, kasamalidwe ndi kutsata makhadi a SIM kumakhala kovuta. Kupatula apo, SIM makadi okhala ndi inkjet osindikizidwa barcode ndi siriyo nambala ndi zosavuta kukopera ndi opanga ena. Chifukwa chake, kusindikiza kwa inkjet kumasiyidwa pang'onopang'ono ndi opanga makhadi a SIM.
Koma tsopano, ndi makina osindikizira a laser, vuto la "zosavuta kufufutika" likhoza kuthetsedwa mwangwiro. Nambala ya barcode ndi siriyo yosindikizidwa ndi makina ojambulira laser ndizokhazikika ndipo sizingasinthidwe. Izi zimapangitsa kuti zambirizo zikhale zosiyana ndipo sizingabwerezedwe. Komanso, laser chodetsa makina Angagwiritsidwenso ntchito pazigawo zamagetsi, PCB, zida, kulankhulana mafoni, mwatsatanetsatane chowonjezera, etc..
Zomwe tazitchula pamwambapa za makina ojambulira laser zili ndi chinthu chimodzi chofanana - malo ogwirira ntchito ndi ochepa kwambiri. Izi zikutanthauza kuti kuyika chizindikiro kuyenera kukhala kolondola kwambiri. Ndipo izi zimapangitsa UV laser kukhala yabwino kwambiri, chifukwa UV laser imadziwika ndi kulondola kwambiri komanso "kuzizira kozizira". Laser ya UV sidzalumikizana ndi zida panthawi yogwira ntchito ndipo malo okhudzidwa ndi kutentha ndi ochepa kwambiri, kotero pafupifupi palibe kutentha komwe kungagwire ntchito pazinthuzo. Chifukwa chake, palibe kuwonongeka kapena kupindika komwe kungachitike. Kusunga zolondola, UV laser nthawi zambiri amabwera ndi odalirika
water chiller unit.
S&A Teyu CWUL mndandanda wamadzi ozizira ndi njira yabwino yoziziritsira makina a UV laser. Imakhala ndi kulondola kwakukulu kwa ± 0.2 ℃ ndi zogwirira zophatikizika zomwe zimalola kuyenda kosavuta. Refrigerant ndi R-134a yomwe ndi yogwirizana ndi chilengedwe ndipo imatha kuchepetsa kukhudzidwa kwa chilengedwe. Dziwani zambiri za CWUL series water chiller unit pa
