Indlela yokwenza ibhodi le-PCB elihle?
Sonke siyazi ukuthi ukwenza ibhodi le-PCB wukuguqula uhlaka oluklanyelwe lube yibhodi le-PCB langempela. Sicela ungayithathi kancane le nqubo. Kunezinto eziningi ezingenzeka ngokomgomo kodwa okunzima ukuzifinyelela kuphrojekthi, noma ezinye zingafinyelela izinto abanye abantu abangakwazi ukuzifeza iMoo...Funda kabanzi -
Indlela yokuklama i-PCB crystal oscillator?
Sivame ukuqhathanisa i-crystal oscillator enhliziyweni yesifunda sedijithali, ngoba wonke umsebenzi wesifunda sedijithali awunakuhlukaniswa nesignali yewashi, futhi i-crystal oscillator ilawula ngokuqondile lonke uhlelo. Uma i-crystal oscillator ingasebenzi, lonke uhlelo luzokhubazeka...Funda kabanzi -
Ukuhlaziywa kwezinhlobo ezintathu ze-PCB stencil technology
Ngokwenqubo, i-pcb stencil ingahlukaniswa ngezigaba ezilandelayo: 1. I-stencil yokunamathisela ye-Solder: Njengoba igama liphakamisa, isetshenziselwa ukuxubha unamathisele we-solder. Baza izimbobo ocezwini lwensimbi oluhambisana namaphedi ebhodi le-pcb. Bese usebenzisa i-solder unama ukupheda ebhodini le-PCB ...Funda kabanzi -
Ibhodi lesifunda seCeramic PCB
Inzuzo: Umthamo omkhulu wamanje wokuthwala, i-100A yamanje idlula ngokuqhubekayo emzimbeni wethusi owugqinsi ongu-1mm0.3mm, ukukhuphuka kwezinga lokushisa cishe ku-17℃; I-100A yamanje idlula ngokuqhubekayo emzimbeni wethusi owugqinsi ongu-2mm0.3mm, ukukhuphuka kwezinga lokushisa cishe ku-5℃. Umsebenzi ongcono wokuqeda ukushisa...Funda kabanzi -
Ungasicabangela kanjani isikhala esiphephile ekwakhiweni kwe-PCB?
Kunezindawo eziningi ekwakhiweni kwe-PCB lapho isikhala esiphephile sidinga ukucatshangelwa. Lapha, ihlukaniswa okwesikhashana izigaba ezimbili: esisodwa esokuhlukaniswa kwezokuphepha okuhlobene nogesi, esinye siyisikhala sokuphepha esingahlobene nogesi. Isikhala sokuphepha esihlobene nogesi 1.Isikhala phakathi kwezintambo Ukufika ...Funda kabanzi -
Ibhodi lesifunda lethusi eliwugqinsi
Ukwethulwa Kobuchwepheshe Bebhodi Le-Copper Circuit Board (1) (1) Ukulungiswa kwangaphambili kokucwenga kanye nokwelashwa kwe-electroplating Injongo eyinhloko yokujiya i-copper plating iwukuba kuqinisekiswe ukuthi kunongqimba olwanele lokucwenga lwethusi emgodini ukuze kuqinisekiswe ukuthi inani lokumelana lingaphakathi kwebanga elidingekayo. ...Funda kabanzi -
Izibaluli ezinhlanu ezibalulekile nezinkinga zesakhiwo se-PCB okufanele zicatshangelwe ekuhlaziyweni kwe-EMC
Kuye kwathiwa kunezinhlobo ezimbili kuphela zonjiniyela be-elekthronikhi emhlabeni: labo abaye babhekana nokuphazanyiswa nguzibuthe kagesi nalabo abangakaze babhekane nakho. Ngokukhula kwemvamisa yesiginali ye-PCB, ukwakheka kwe-EMC kuyinkinga okufanele siyicabangele 1. Izibaluli ezinhlanu ezibalulekile okufanele zicatshangelwe ngesikhathi...Funda kabanzi -
Liyini iwindi lemaski le-solder?
Ngaphambi kokwethula iwindi lemaski ye-solder, kufanele siqale sazi ukuthi iyini imaski ye-solder. Imaski ye-solder isho ingxenye yebhodi lesekethe ephrintiwe ezofakwa u-inki, esetshenziselwa ukumboza iminonjana nethusi ukuvikela izakhi zensimbi ku-PCB futhi kuvinjwe amasekhethi amafushane. Isici sokuvula imaski yesoda...Funda kabanzi -
Umzila we-PCB ubaluleke kakhulu!
Uma wenza umzila we-PCB , ngenxa yomsebenzi wokuhlaziya wangaphambili ungenziwanga noma ungenziwanga, ukucubungula ngemva kokucubungula kunzima. Uma ibhodi le-PCB liqhathaniswa nedolobha lethu, izingxenye zifana nomugqa phezu komugqa wazo zonke izinhlobo zezakhiwo, imigqa yesignali iyimigwaqo nemigwaqo edolobheni, i-flyover roundabou...Funda kabanzi -
Imbobo yesitembu se-PCB
I-Graphitization ngokufaka i-electroplating emigodini noma ngezimbobo emaphethelweni e-PCB. Sika unqenqema lwebhodi ukuze wenze uchungechunge lwezimbobo eziyisigamu. Lezi zimbobo eziwuhhafu yizo esizibiza ngama-stamp hole pads. 1. Ububi bezimbobo zezitembu ①: Ngemuva kokuthi ibhodi selihlukene, linomumo ofana nesaha. Abanye abantu babiza...Funda kabanzi -
Yimuphi umonakalo oyobangela ukubamba ibhodi le-PCB ngesandla esisodwa ebhodini lesekethe?
Emhlanganweni we-PCB kanye nenqubo yokuhlanganisa, abakhiqizi be-SMT chip processing banabasebenzi abaningi noma amakhasimende abambe iqhaza ekusebenzeni, njengokufakwa kwe-plug-in, ukuhlolwa kwe-ICT, ukuhlukaniswa kwe-PCB, ukusebenza kwe-PCB esebenza ngesandla, ukukhweza isikulufu, ukukhweza i-rivet, ukucindezela manual kwesixhumi se-crimp, PCB cyclin...Funda kabanzi -
