SMD sumo
SMT patch inoreva kupfupikiswa kwenhevedzano yemaitiro maitiro akagadziriswa pahwaro hwePCB.PCB (Printed Circuit Board) ibhodhi redunhu rakadhindwa.
SMT is Surface Mount Technology (Surface Mount Technology) (pfupiso yeSurface Mounted Technology), inova ndiyo inonyanya kufarirwa tekinoroji uye maitiro muindasitiri yegungano remagetsi.
Tekinoroji yedunhu repamusoro musangano tekinoroji (Surface Mount Technology, SMT), inozivikanwa seyepamusoro gomo kana pamusoro pekukwira tekinoroji.Iyo imhando yeasiri-pini kana mapfupi-anotungamira epamusoro ekumusoro zvikamu (SMC/SMD kwenguva pfupi, Chinese inonzi chip components) yakaiswa pamusoro peiyo yakadhindwa redunhu bhodhi (Printed Circuit Board, PCB) kana pamusoro pemamwe ma substrates, kuburikidza neCircuit assembly uye yekubatanidza tekinoroji inotengeswa uye inounganidzwa nenzira dzakadai sereflow soldering kana dip soldering.
Mumamiriro ezvinhu akajairwa, zvigadzirwa zvemagetsi zvatinoshandisa zvakagadzirirwa nePCB pamwe neakasiyana macapacitor, resistors uye zvimwe zvinhu zvemagetsi zvinoenderana nedhizaini yakagadzirwa, saka marudzi ese emidziyo yemagetsi inoda akasiyana eSMT chip processing tekinoroji kuti agadzirise, basa rayo ndere leak solder paste kana chigamba glue pamapadhi ePCB kugadzirira kushambadzira kwezvikamu.Midziyo inoshandiswa muchina wekudhinda screen (screen printing machine), iyo iri kumberi kweSMT mutsara wekugadzira.
Basic process yeSMT
1. Kudhinda (kudhinda silika): Basa rayo nderekudhinda solder paste kana chigamba chinonamira pamapedhi ePCB kugadzirira kushambadzira kwezvikamu.Midziyo inoshandiswa muchina wekudhinda screen (screen printing machine), iyo iri kumberi kweSMT mutsara wekugadzira.
2. Glue kugovera: Iko kudonhedza glue panzvimbo yakagadziriswa yePCB board, uye basa rayo guru nderokugadzirisa zvikamu kuPCB board.Midziyo inoshandiswa ndeye glue dispenser, iyo iri kumberi kweiyo SMT mutsara wekugadzira kana kuseri kwemidziyo yekuyedza.
3. Kukwirisa: Basa rayo nderekunyatsoisa zvikamu zvekukwira pamusoro penzvimbo yakagadziriswa yePCB.Midziyo inoshandiswa muchina wekuisa, uyo uri kuseri kwechidzitiro chekudhinda muchina mutsetse wekugadzira SMT.
4. Kurapa: Basa rayo nderokunyungudusa chigamba chekunamatira, kuitira kuti zvikamu zvekukwira pamusoro uye PCB board zvibatanidzwe zvakasimba pamwe chete.Midziyo inoshandiswa ihovhoni inorapa, iri kuseri kwemuchina wekuisa mumutsara wekugadzira weSMT.
5. Reflow soldering: Basa rayo nderokunyungudusa solder paste, kuitira kuti nzvimbo yepamusoro yepamusoro uye PCB board zvibatanidzwe zvakasimba pamwe chete.Midziyo inoshandiswa ndeye reflow oveni / wave solder, iri kuseri kwemuchina wekuisa mumutsara wekugadzira weSMT.
6. Kuchenesa: Basa rayo nderokubvisa masara ekuputira anokuvadza kumuviri wemunhu zvakadai sekuyerera pane yakaungana PCB board.Midziyo inoshandiswa muchina wekuwachisa, uye nzvimbo yacho inogona kusagadziriswa, pamhepo kana pamhepo.
7. Kuongorora: Basa rayo nderokuongorora kunaka kwewelding uye gungano rehutano hwePCB board yakaungana.Midziyo inoshandiswa inosanganisira girazi rekukudza, maikorosikopu, online tester (ICT), flying probe tester, automatic optical inspection (AOI), X-RAY inspection system, functional tester, etc. Nzvimbo yacho inogona kugadzirwa panzvimbo yakakodzera pamutsetse wekugadzira. maererano nezvinodiwa zvekuonekwa.
Maitiro eSMT anogona kuvandudza zvakanyanya kugadzirwa uye huchokwadi hweakadhindwa edunhu mabhodhi, uye kunyatsoona otomatiki uye kugadzirwa kwakawanda kwePCBA.
Kusarudza michina yekugadzira inokodzera iwe unogona kazhinji kuwana zvakapetwa kaviri mhedzisiro nehafu yekuedza.Chengyuan Industrial Automation inopa rubatsiro rwekumira-imwe uye sevhisi yeSMT nePCBA, uye inoronga hurongwa hwekugadzira hwakakunakira iwe.
