Umsebenzi kunye nokuhamba komsebenzi wesilayishi se-SMT

Indima yesilayishi se-SMT

Umlayishi we-SMT PCB luhlobo lwezixhobo zemveliso ezifunekayoUmgca wemveliso we-SMT.Umsebenzi wayo ophambili kukubeka ibhodi ye-PCB engaqhotyoshelwanga kumatshini wokufaka ipleyiti ye-SMT kwaye ngokuzenzekelayo ukondla ibhodi kumatshini wepleyiti yokufunxa.Emva koko umatshini wepleyiti yokufunxa uya kubeka ngokuzenzekelayo iPCB kumzila weistensileumatshini wokushicilelakwaye uyilayishe kumatshini wokushicilela we-stencil ukuze usebenze ngokucolwa kwebrashi ye-solder.

Inkqubo yokusebenza eneenkcukachaPCBumthwaloer

I. ukulungiselela

1. Vula umbane kwaye uvule iswitshi yamandla;

2. Lungisa ububanzi bomzila kaloliwe de bube bufana nobubanzi bebhodi yePCB eza kuveliswa.

II.Cwangcisa inani lamanyathelo okutyisa ipleyiti kunye nendawo yokuphuma kweplate (phantsi kwemeko yezandla kunye neqonga lokunyusa likwindawo esezantsi yomda)

1. Ukusetha inyathelo: cofa iqhosha ukukhetha Pitch 1/2/3/4;

2, ngaphandle kohlengahlengiso lwebhodi;

3. Lungisa ngesandla intonga yokutyhala embindini wePCB eza kuveliswa;

4. Qinisekisa ukuba umatshini unokuthumela ibhodi ngokufanelekileyo (indawo yesiqwenga sokuqala sebhodi);

5. Cofa iqhosha elizenzekelayo (ukutshintshela kwi-othomathikhi);

6. Cinezela iqhosha lokubuyisela (iqonga lokuphakamisa liya kuhla ngokuzenzekelayo kumda ophantsi kwaye emva koko ubuyele kwindawo yokuqala yokuphuma);

7. Imeko ezenzekelayo.

III.Ukutya

1. Lungisa i-anti-static material rack kububanzi obufanayo nebhodi ye-PCB eya kuveliswa, yilayishe kwibhodi ye-PCB kwaye uyibeke kwiqonga lokuthwala kwibhodi ephezulu;
2. Cofa iqhosha elizenzekelayo kwiphaneli yokusebenza kwebhodi;

IV.iimfuno zokusebenza ezikhuselekileyo

1. Nceda uqaphele ukuba i-voltage yokusebenza kunye noxinzelelo lomoya ichanekile xa uqalisa umatshini;

2. Ngexesha lokusebenza ngokuzenzekelayo, kucetyiswa ukuba ungasebenzisi ezinye izitshixo ngaphandle kokuba iqhosha likaxakeka licinezelwe kwimeko yongxamiseko;

3. Abasebenzi abavumelekanga ukuba baxhomekeke okanye baxhomekeke kumatshini;

4. Xa uphakamisa imoto, musa ukubeka izandla zakho malunga nesakhelo sezinto eziphathekayo;

5. nikela ingqalelo ukulungelelanisa isithuba seplate yesakhelo sokutya, ebanzi lula ukukhokelela ukulahla ipleyiti, lukhuni lula ukukhokelela kwipleyiti yekhadi;

6. nikela ingqalelo ukulungelelanisa ububanzi bebhanti yokuhambisa, ebanzi lula ukukhokelela ukulahla ipleyiti, iqinile kulula ukukhokelela kwikhadi.
