Umlando omfushane wokuthuthukiswa kwamabhodi esekethe aphrintiwe
Njengezinye izinto eziningi ezinhle eziqanjiwe kuwo wonke umlando, ibhodi lesifunda eliphrintiwe (PCB) njengoba silazi namuhla lisekelwe ekuqhubekeleni phambili okwenziwe kuwo wonke umlando.Ekhoneni lethu elincane lomhlaba, singakwazi ukulandelela umlando wama-PCB emuva eminyakeni engaphezu kwe-130, lapho imishini yezimboni emikhulu emhlabeni yayi...Funda kabanzi -
Indlela yokwenza ibhodi lesifunda se-pcb
Ngokukhiqizwa kwe-PCB eyimfundamakhwela, ukuphrinta kokudlulisa okushisayo nokuchayeka kwe-UV izindlela ezimbili ezivame ukusetshenziswa.Izinto ezisetshenziswayo ezidinga ukusetshenziswa endleleni yokudlulisa okushisayo yilezi: i-copper clad laminate, iphrinta ye-laser (kumele kube iphrinta ye-laser, iphrinta ye-inkjet, iphrinta ye-dot matrix namanye amaphrinta akuzona...Funda kabanzi -
Yiziphi izimiso zokuklama ze-PCB
Ukuze kuzuzwe ukusebenza okuhle kakhulu kwamasekethe e-elekthronikhi, ukuhlelwa kwezingxenye kanye nomzila wezintambo kubaluleke kakhulu.Ukuze uklame i-PCB enekhwalithi enhle nezindleko eziphansi.Izimiso ezijwayelekile ezilandelayo kufanele zilandelwe: isakhiwo Okokuqala, cabangela ubukhulu be-PCB.Uma usayizi we-PCB ngi...Funda kabanzi -
Isingeniso esinemininingwane eminingi mayelana ne-PCB
I-PCB yenziwe ngobuchwepheshe bokuphrinta be-elekthronikhi, ngakho ibizwa ngokuthi ibhodi lesifunda eliphrintiwe.Cishe lonke uhlobo lwemishini kagesi, kusukela kuma-earphone, amabhethri, okokubala, kuya kumakhompyutha, izinto zokuxhumana, izindiza, amasathelayithi, inqobo nje uma izingxenye zikagesi ezifana nesekhethi edidiyelwe...Funda kabanzi -
Iyini intengo evamile yamabhodi esekethe aphrintiwe
Isingeniso Ngokuya ngokwakhiwa kwebhodi lesifunda, intengo izohluka kuye ngezinto zebhodi lesifunda, inani lezendlalelo zebhodi lesifunda, ubukhulu bebhodi lesifunda, inani lomkhiqizo ngamunye, inqubo yokukhiqiza, ubuncane bobubanzi bomugqa nesikhala somugqa...Funda kabanzi -
Ukuhlolwa nokulungiswa kwe-PCB
1. I-Chip enohlelo 1. Ama-EPROM chips ngokuvamile awafanele umonakalo.Ngoba lolu hlobo lwe-chip ludinga ukukhanya kwe-ultraviolet ukuze lusule uhlelo, ngeke lulimaze uhlelo phakathi nokuhlolwa.Kodwa-ke, kukhona ulwazi: ngenxa yezinto ezisetshenziselwa ukwenza i-chip, njengoba isikhathi sihamba isikhathi eside), ngisho ...Funda kabanzi -
Mayelana nesicelo esisebenzayo namaphrojekthi amasha we-PCBA
Okusebenzayo Ekupheleni kweminyaka yawo-1990 lapho kuhlongozwa izixazululo eziningi zebhodi lesekethe eliphrintiwe, amabhodi esekethe aphrintiwe asetshenziswa ngokusemthethweni asetshenziswa ngobuningi kuze kube manje.Kubalulekile ukwakha isu lokuhlola eliqinile lesekethe enkulu ephrintiwe...Funda kabanzi -
