SMT kugadzirisainoteedzana tekinoroji tekinoroji yekugadzirisa pahwaro hwePCB. Iyo ine mabhenefiti ekukwira kwepamusoro kurongeka uye nekukurumidza kukurumidza, saka yakagamuchirwa nevakawanda vanogadzira zvemagetsi. Iyo SMT chip process process inonyanya kusanganisira sirika screen kana glue kugovera, kukwira kana kurapa, reflow soldering, kuchenesa, kuyedza, rework, etc. Maitiro akawanda anoitwa nenzira yakarongeka kupedzisa iyo yose chip process process.
1.Screen kudhinda
Iyo yekumberi-yekupedzisira midziyo iri muSMT yekugadzira mutsara muchina wekudhinda skrini, iyo basa guru ndere kudhinda solder paste kana chigamba glue pamapads ePCB kugadzirira kushambadzira kwezvikamu.
2. Kugovera
Midziyo iri kumberi kwekupedzisira kweSMT yekugadzira mutsara kana kuseri kwemuchina wekuongorora kune glue dispenser. Basa rayo guru nderekudonhedza glue panzvimbo yakagadziriswa yePCB, uye chinangwa ndechekugadzirisa zvikamu paPCB.
3. Kuiswa
Zvishandiso zviri kuseri kwesiriki skrini yekudhinda muchina muSMT yekugadzira mutsara muchina wekuisa, unoshandiswa kunyatso kwidza pamusoro pepamusoro zvikamu zvekuisa panzvimbo yakatarwa paPCB.
4. Kurapa
Zvishandiso zviri kuseri kwemuchina wekuisa mumutsara wekugadzira weSMT ivira rinorapa, iro basa guru rekunyungudutsa glue yekuisa, kuitira kuti zvikamu zvegomo repamusoro uye bhodhi rePCB zvibatanidzwe zvakasimba pamwechete.
5. Reflow soldering
Zvishandiso zviri kuseri kwemuchina wekuisa mumutsara wekugadzira weSMT ihovhoni yekuyerera, iyo basa guru rekunyungudutsa solder paste kuitira kuti zvinhu zvekukwira pamusoro uye bhodhi rePCB zvibatane zvakasimba.
6. Kuonekwa
Kuti ive nechokwadi chekuti hunhu hwekutengesa uye kunaka kwekusangana kwePCB board yakaunganidzwa inosangana nezvinodiwa nefekitori, magirazi ekukudza, mamicroscopes, in-circuit testers (ICT), inobhururuka probe testers, otomatiki optical inspection (AOI), X-RAY yekuongorora masisitimu. nemimwe midziyo inodiwa. Basa guru nderekuona kuti PCB board ine hurema hwakadai senge chaiyo solder, kushaikwa soldering, uye kutsemuka.
7. Kuchenesa
Panogona kunge paine zvisaririra zvekutengesa zvinokuvadza kumuviri wemunhu sekuyerera paPCB board yakaunganidzwa, inoda kucheneswa nemuchina wekuchenesa.
