Kungani ama-PCB kudingeka enziwe ku-Panel?
From PCBworld, 01 Kungani iphazili Ngemva kokuthi ibhodi lesifunda seliklanywe, ulayini wokuhlanganisa isichibi se-SMT udinga ukunamathiselwa ezingxenyeni. Imboni ngayinye yokucubungula i-SMT izocacisa usayizi ofaneleka kakhulu webhodi lesifunda ngokuvumelana nezidingo zokucubungula zomugqa womhlangano. F...Funda kabanzi -
Ubhekene ne-PCB enesivinini esikhulu, ingabe unayo le mibuzo?...
Kusuka emhlabeni we-PCB, Mashi, 19, 2021 Uma senza idizayini ye-PCB, sivamise ukuhlangana nezinkinga ezihlukahlukene, ezifana nokufanisa i-impedance, imithetho ye-EMI, njll. Lesi sihloko sihlanganise imibuzo nezimpendulo ezihlobene nama-PCB anesivinini esikhulu kuwo wonke umuntu, futhi ngiyethemba kuyoba usizo kuwo wonke umuntu. 1. Kanjani...Funda kabanzi -
Indlela elula nesebenzayo ye-PCB yokukhipha ukushisa
Ngemishini ye-elekthronikhi, inani elithile lokushisa likhiqizwa ngesikhathi sokusebenza, ukuze izinga lokushisa langaphakathi lemishini likhuphuke ngokushesha. Uma ukushisa kungachithwa ngesikhathi, okokusebenza kuzoqhubeka nokushisa, futhi idivayisi izohluleka ngenxa yokushisa ngokweqile. Ukuthembeka kwe-ele...Funda kabanzi -
Uyazazi izidingo ezinhlanu ezinkulu zokucubungula nokukhiqiza kwe-PCB?
1. Usayizi we-PCB [Incazelo engemuva] Usayizi we-PCB unqunyelwe umthamo wezinto zomugqa wokukhiqiza osebenza ngogesi. Ngakho-ke, usayizi ofanele we-PCB kufanele ucatshangelwe lapho uklama uhlelo lohlelo lomkhiqizo. (1) Umkhawulo kasayizi we-PCB ongafakwa ku-SMT equi...Funda kabanzi -
Unganquma kanjani ukuthi usebenzise isendlalelo esisodwa noma i-PCB enezingqimba eziningi ngokuya ngezidingo zomkhiqizo?
Ngaphambi kokuklama ibhodi lesifunda eliphrintiwe, kuyadingeka ukunquma ukuthi usebenzise isendlalelo esisodwa noma i-PCB enezingqimba eziningi. Zombili izinhlobo zokuklama zivamile. Ngakho-ke yiluphi uhlobo olulungele iphrojekthi yakho? Uyini umehluko? Njengoba igama lisho, ibhodi elinesendlalelo esisodwa linesendlalelo esisodwa kuphela se-base materia...Funda kabanzi -
Izici zebhodi lesifunda elinamahlangothi amabili
Umehluko phakathi kwamabhodi wesifunda anohlangothi olulodwa kanye namabhodi wesifunda anezinhlangothi ezimbili yinani lezingqimba zethusi. Isayensi edumile: amabhodi wesifunda anezinhlangothi ezimbili anethusi ezinhlangothini zombili zebhodi lesifunda, elingaxhunywa nge-vias.
