PCBA Short Circuit Troubleshooting Solution

Kana iyo PCB dhizaini yapera, isu tinofanirwa kuitarisa kune ese maficha eprojekiti.Sezvakangoita kana tapedza bepa rebvunzo tiri toga, tinofanira kuita ongororo yakapusa totarisa matambudziko aro ese zvakare, kuitira kuti tive nechokwadi chekuti hatizokanganisa zvakanyanya nekuda kwekuregeredza.Inotevera neoden Mounter vagadziri kutsanangura nzira yekugadzirisa PCBA kugadzirisa mapfupi edunhu zvikanganiso zvine chekuita neruzivo.

1. Vhura PCB yakagadzirwa pakombiyuta, iyo pfupi-circuit network inovhenekera, ona kuti ndeipi nzvimbo iri pedo, iyo inonyanya kubatanidza kune chidimbu.Chengetedza zvakanyanya kune IC yemukati pfupi dunhu.Kana manual soldering, kukudziridza tsika dzakanaka :.

2. Asati soldering kuti manually nemaziso kuongorora PCB bhodhi kamwe, uye kushandisa multimeter kuti atarise kiyi matunhu (kunyanya magetsi uye pasi) kana pfupi-wedunhu.

3. Nguva imwe neimwe mushure mekubatanidza chip kushandisa multimeter kuyera simba rekupa uye pasi kana pane pfupi pfupi.

4. PCBA kugadzirwa solder nguva regai kukanda simbi, netsaona kukanda solder kuti chip solder tsoka (kunyanya tafura sticker zvinoumba), hazvisi nyore kuwana pfupi-wedunhu chiitiko.Tora bhodhi kuti ucheke mutsara (kunyanya wakakodzera kune imwe chete / kaviri layer board), cheka mutsara mushure mechikamu chimwe nechimwe chezvivharo zvekushanda zvakasimbiswa, uye zvishoma nezvishoma zvakabviswa.

5. Kushandiswa kwezviridzwa zvekuongorora nzvimbo yenguva pfupi.

6. PCBA chip processing BGA chip, nekuda kwezvose zvinotengesa zvibatanidza zvakafukidzwa ne chip chisingaoneki, uye multi-layer board (kupfuura 4 layers), zvino zviri nani kuparadzanisa magetsi mukugadzirwa kwechipi chimwe nechimwe, ne magineti bead kana 0 ohm yemagetsi zuva kubatana, kuitira kuti kune simba rekupa ine pfupi pfupi kutenderera pasi, ichibvisa iyo magnetic bead yekuona, zviri nyore kwazvo kuona chizvarwa kune chip.Nekuda kwekuomerwa kweBGA soldering, manual welding, kana ikasangwarira ichave yakatarisana nemagetsi uye pasi maviri solder mabhora mapfupi-circuited.

7. Diki-sized table table sticker capacitor welding inofanira kuchenjerera, kunyanya magetsi ekugadzirisa sefa capacitor (103 kana 104), nhamba huru, zviri nyore kukonzera magetsi uye pasi pfupi.
