Anokwikwidza PCB Mugadziri

SMT ndiyo chidimbu cheSurface Mounted Technology, inonyanya kufarirwa Tekinoroji uye maitiro muindasitiri yegungano remagetsi.Yemagetsi redunhu Surface Mount Technology (SMT) inonzi Surface Mount kana Surface Mount Technology.Imhando yeTekinoroji yedunhu tekinoroji inoisa isina lead kana ipfupi lead surface musangano zvikamu (SMC/SMD muchiChinese) pamusoro pePrinted Circuit Board (PCB) kana imwe substrate surface, yobva yasungirira nekuunganidza nenzira yereflow welding kana. dip welding.

Kazhinji, zvigadzirwa zvemagetsi zvatinoshandisa zvinogadzirwa nePCB pamwe neakasiyana macapacitor, resistors uye zvimwe zvinhu zvemagetsi zvinoenderana nedhiyagiramu yedunhu, saka marudzi ese emidziyo yemagetsi inoda akasiyana SMT chip processing tekinoroji kuti igadzirise.

SMT basic process zvinhu zvinosanganisira: kudhinda skrini (kana kugovera), kukwira (kurapa), reflow welding, kuchenesa, kuyedza, kugadzirisa.

1. Kudhinda sikirini: Basa rekudhinda sikirini nderekudonhedza solder paste kana chigamba chinonamira paPCB's solder pad kugadzirira welding yezvikamu.Midziyo inoshandiswa muchina wekudhinda screen (screen printing machine), iri kumberi kwe SMT mutsara wekugadzira.

2. Glue spraying: Inodonhedza glue kune yakagadziriswa nzvimbo yePCB board, uye basa rayo guru nderokugadzirisa zvikamu kuPCB board.Midziyo inoshandiswa muchina wekuparadzira, uri kumberi kwekupedzisira kweSMT mutsara wekugadzira kana kuseri kwemidziyo yekuyedza.

3. Gomo: Basa rayo nderekuisa zvikamu zvemusangano wepamusoro nenzira kwayo kune yakagadziriswa nzvimbo yePCB.Midziyo inoshandiswa ndeye SMT yekuisa muchina, iri kuseri kwechidzitiro chekudhinda muchina muiyo SMT yekugadzira mutsara.

4. Kurapa: Basa rayo nderokunyungudutsa SMT adhesive kuitira kuti zvikamu zvemusangano wepamusoro uye PCB board inogona kunamatira zvakasimba pamwe chete.Midziyo inoshandiswa kurapa choto, iri kuseri kweSMT SMT mutsara wekugadzira.

5. Reflow welding: basa re reflow welding ndeyekunyungudutsa solder paste, kuitira kuti zvikamu zvegungano repamusoro uye bhodhi rePCB zvibatane zvakasimba.Midziyo inoshandiswa ndeye reflow welding vira, iri muSMT yekugadzira mutsara kuseri kweiyo SMT yekuisa muchina.

6. Kuchenesa: Basa racho nderokubvisa zvakasara zvewelding zvakadai sekuputika paPCB yakaungana iyo inokuvadza kumuviri wemunhu.Midziyo inoshandiswa muchina wekuchenesa, chinzvimbo hachigone kugadziriswa, chinogona kuve online, kana kwete online.

7. Kuona: Inoshandiswa kuona kunaka kwewelding uye gungano remhando yePCB yakaungana.Midziyo inoshandiswa inosanganisira girazi rekukudza, maikorosikopu, chiridzwa chekuedza pa-line (ICT), chiridzwa chekuongorora tsono chinobhururuka, otomatiki optical test (AOI), X-ray test system, chimbo chekuedza chekushanda, nezvimwewo. Nzvimbo yacho inogona kugadzirwa nenzira yakakodzera. chikamu chemutsetse wekugadzira maererano nezvinodiwa zvekuongorora.

8.Kugadzirisa: inoshandiswa kugadzirisa zvakare PCB yakaonekwa nekukanganisa.Zvishandiso zvinoshandiswa simbi dzekutengesa, kugadzirisa nzvimbo dzekushanda, nezvimwewo. Kugadziriswa kuri kupi zvako mumutsara wekugadzira.
