Yakanyanya Tembiricha Kudzora kweLaser Systems uye Maindasitiri Zvishandiso Kubva 2002
Mutauro
Muindasitiri yekugadzira zvigadzirwa zvemagetsi, Surface Mount Technology (SMT) yakakosha. Yakasimba tembiricha uye humidity control, inochengetedzwa nemidziyo yekutonhodza semvura inotonhorera, inova nechokwadi chekushanda kwakanaka uye kudzivirira kukanganisa. SMT inokwidziridza mashandiro, kushanda zvakanaka, uye kuderedza mutengo uye kukanganisa kwezvakatipoteredza, zvichisara pakati pekufambira mberi mune ramangwana mukugadzira zvemagetsi.
Muindasitiri yanhasi inokurumidza kubuda yekugadzira zvigadzirwa zvemagetsi, Surface Mount Technology (SMT) inoita basa rakakosha. Tekinoroji yeSMT inosanganisira kuiswa chaiko kwezvikamu zvemagetsi paPrinted Circuit Boards (PCBs) izvo zvisina kungo fambisa miniaturization, kureruka, uye kukwidziridzwa kuita kwezvigadzirwa zvemagetsi, asi zvakare yakavandudza zvakanyanya kuvimbika kwechigadzirwa uye kugona kugadzira uku ichideredza mitengo yekugadzira.
Basic Maitiro eSMT Surface Mounting
Maitiro ekukwira pamusoro peSMT akanyatsojeka uye anoshanda, anosanganisira akati wandei matanho akakosha:
Solder Paste Printing: Kuisa solder paste pane chaiwo mapedhi paPCB kugadzirira chaiyo chikamu chekuisa pamusoro.
Part Mounting: Kushandisa yakakwirira-chaiyo yepamusoro yekukwira system yekuisa zvinhu zvemagetsi pane solder-pasted pads.
Reflow Soldering: Kunyungudutsa solder paste muhovheni inoyerera kuburikidza nemhepo inopisa yekutenderera kuti isungirire zvakasimba zvikamu zvemagetsi kuPCB.
Automated Optical Inspection (AOI): Michina yeAOI inoongorora kunaka kwePCB yakatengeswa kuona kuti hapana chakakanganisika sezvikamu zvisiri izvo, zvidimbu zvisipo, kana kudzoka shure.
X-Ray Kuongorora: Kushandisa X-ray yekuongorora midziyo yekudzika-nhanho yehutongi hwemajoini akavanzika ekutengesa, seaya ari muBall Grid Array (BGA) kurongedza.
Kudzora Kudzora Zvinodiwa muMamiriro Ekugadzira
Mitsetse yekugadzira yeSMT ine zviyero zvakasimba zvekushisa uye hunyoro munzvimbo yebasa. Kudzora tembiricha kwakakosha kuchengetedza kugadzikana kwemidziyo uye yemhando yekutengesa, kunyanya munzvimbo dzine tembiricha yepamusoro:
Equipment Temperature Control: Zvishandiso zveSMT, kunyanya masisitimu ekumisikidza uye maovheni ekuyerera, anogadzira kupisa kwakanyanya panguva yekushanda. Midziyo yekutonhodza yekurudyi inodzivirira kupisa uye inovimbisa kuenderera mberi kwakagadzikana kushanda.
Zvinodiwa Mafambiro Akakosha:Zvishandiso zvekutonhodza inobatsira kuchengetedza inodiwa yakaderera-tembiricha nharaunda kune tembiricha-sensitive zvikamu kana chaiyo solder maitiro.
Kutonhodza midziyo yakadai maindasitiri mvura chillers kwakakosha kuchengetedza kushanda kwakanaka kwemitsara yekugadzira, kudzivirira kukanganisa kwekutengesa kana kuderedzwa kwekuita kunokonzerwa nekupisa kwakanyanya.
Mabhenefiti ezvakatipoteredza eSMT Surface Mounting
SMT tekinoroji inoburitsa tsvina shoma panguva yekugadzira, iri nyore kudzoreredza nekurasa. Izvi zvinoita kuti SMT igadzirise tekinoroji ive nehushamwari uye ishande nesimba. Mukutarisa kwanhasi kwepasirese nezvekuchengetedzwa kwezvakatipoteredza uye kusimudzira kwakasimba, tekinoroji yeSMT zvishoma nezvishoma iri kuita nzira yakasarudzika muindasitiri yekugadzira zvemagetsi.
SMT pamusoro pekukwira tekinoroji isimba rinotyaira kuseri kwekusimudzira kweindasitiri yekugadzira zvemagetsi. Izvo hazvingokwidzi kuita uye kugona kugadzira kwezvigadzirwa zvemagetsi asiwo zvinobatsira mukudzikisa mutengo wekugadzira uye kuderedza kukanganiswa kwezvakatipoteredza. Nekuenderera mberi kwetekinoroji, SMT kumusoro kukwira kucharamba ichiita basa rekutanga mune ramangwana rekugadzira zvemagetsi.
Tiripo nokuda kwenyu kana muchitida.
Ndapota zadza fomu kuti ubate nesu, uye isu tichafara kukubatsira.

TEYU S&A Chiller yakavambwa muna 2002 iine makore makumi maviri nematatu echiller yekugadzira ruzivo, uye ikozvino inozivikanwa seyekutonhora tekinoroji piyona uye akavimbika shamwari muindasitiri yelaser.
