1. Isikhala phakathi kwama-patches
Isikhala phakathi kwezakhi ze-SMD kuyinkinga ukuthi onjiniyela kufanele banake ngesikhathi sesakhiwo. Uma izikhala zincanyana kakhulu, kunzima kakhulu ukuphrinta ukunamathisela umthengisi futhi ugweme ukuthengisa nokutholwa.
Izincomo zebanga zimi ngokulandelayo
Izidingo zebanga ledivayisi phakathi kwama-patches:
Uhlobo olufanayo lwamadivayisi: ≥0.3mm
Imishini yokungafani
Ibanga phakathi kwezakhi ezingafakwa kuphela nge-pat: ≥1.5mm.
Iziphakamiso ezingenhla zenzelwe ukubhekiswa kuphela, futhi zingalandela imininingwane yenqubo yenqubo ye-PCB yezinkampani ezifanele.
2. Ibanga phakathi kwensiza entanjeni kanye nesichibi
Kufanele kube nebanga eyanele phakathi kwedivaysi yokumelana ne-line ne-patch, futhi kunconywa ukuba phakathi kuka-1-3mm. Ngenxa yokucubungula okunzima, ukusetshenziswa kwama-plug-plug-ins akuvamile manje.
3. Ukubekwa kwe-IC Demoupling Capacitors
I-capacitor ekhohlisa kufanele ibekwe eduze kwetheku lamandla e-IC ngayinye, futhi indawo kufanele ibe isondele ngangokunokwenzeka ethekwini lamandla we-IC. Lapho i-chip inamachweba amaningi wamandla, i-capacitor yokukhohlisa kufanele ibekwe ethekwini ngalinye.
4. Naka indlela yokuqondisa nokubekwa kwezakhi onqenqemeni lwebhodi le-PCB.
Njengoba i-PCB yenziwe nge-jigsaw, amadivaysi aseduze komphetho adinga ukufeza izimo ezimbili.
Owokuqala ukufana nesiqondiso sokusika (ukwenza ukucindezelwa kwemishini komfaniswano wedivayisi. Isibonelo, uma idivaysi ibekwa eceleni kwesibalo senhla ngaphezulu, izinkomba zamandla ahlukene ezinhlamvu ezimbili zesikhwama zingadala ukwahlukaniswa. Disc off)
Okwesibili ukuthi izingxenye azikwazi ukuhlelwa ngaphakathi kwebanga elithile (ukuvimbela ukulimala kwezakhi lapho ibhodi linqunywe)
5. Naka izimo lapho amaphaphu asondelene nawo adinga ukuxhunywa khona
Uma amaphaphu asondelene nawo adinga ukuxhunywa, okokuqala qinisekisa ukuthi ukuxhumana kwenziwa ngaphandle ukuvikela ukubopha okubangelwa ukuxhumana okubangelwa ukuxhumana, futhi unake ububanzi bocingo lwethusi ngalesi sikhathi.
6. Uma i-pad iwela endaweni ejwayelekile, ukuncipha kokushisa kudinga ukucatshangelwa
Uma i-pad iwela endaweni egandayiwe, indlela efanele kufanele isetshenziselwe ukuxhuma i-pad nepasi. Futhi, nquma ukuthi uxhumeka yini umugqa ongu-1 noma imigqa emi-4 ngokuya ngentengo yamanje.
Uma indlela ngakwesobunxele yamukelwa, kunzima ngokwengeziwe ukuwela noma ukulungiswa kanye nokuhlukaniswa izakhi, ngoba izinga lokushisa lihlakazeka ngokuphelele yiCopper elibekiwe, elenza ukufudumala ngokuphelele.
7. Uma ukuhola kuncane kune-plug-in pad, i-teardrop iyadingeka
Uma ucingo luncane kune-pad of the-line in-divayisi, udinga ukwengeza ama-teardrops njengoba kukhonjisiwe ngakwesokunene kwesibalo.
Ukungeza i-Teardrops inezinzuzo ezilandelayo:
.
(2) Inkinga ukuthi ukuxhumana okuphakathi kwe-pad kanye nomkhondo kuphulwe kalula ngenxa yomthelela kuxazululwa.
(3) Ukuhlelwa kwama-teardrops nakho kungenza ibhodi yesekethe ye-PCB ibukeke ibe yinhle ngokwengeziwe.
