Iyo ukoraInzira ya PCB, kubera isesengura ryibanze ryakazi ntirikorwa cyangwa ntirikorwa, nyuma yo gutunganya biragoye. Niba ikibaho cya PCB kigereranijwe numujyi wacu, ibice bimeze nkumurongo kumurongo wububiko bwubwoko bwose, imirongo yerekana ibimenyetso ni imihanda ninzira nyabagendwa mumujyi, ikirwa kizenguruka ikizunguruka, kugaragara kwa buri muhanda nigishushanyo mbonera cyacyo, insinga nazo kimwe.
1. Kwifuza ibyingenzi
A) Imirongo yingenzi yibimenyetso irahitamo: gutanga amashanyarazi, kugereranya ibimenyetso bito, ibimenyetso byihuta cyane, ibimenyetso byisaha, ikimenyetso cyo guhuza nibindi bimenyetso byingenzi birahitamo.
B) Ihame ryibanze ryibanze: Tangira wiring kuva mubice bifite isano ihuza cyane kurubaho. Cabling itangirira kumwanya uhujwe cyane kurubaho.
C) Icyitonderwa mugutunganya ibimenyetso byingenzi: gerageza gutanga umurongo wihariye wiring kubimenyetso byingenzi nkibimenyetso byamasaha, ibimenyetso byumuvuduko mwinshi nibimenyetso byoroshye, kandi urebe neza ahantu hakeye. Nibiba ngombwa, gukingira no kongera intera yumutekano bigomba kwemerwa. Menya neza ibimenyetso byerekana ibimenyetso.
D) Umuyoboro ufite ibisabwa byo kugenzura inzitizi ugomba gutondekwa kurwego rwo kugenzura inzitizi, kandi ibimenyetso byambukiranya ibice bizirindwa.
2.Wiring scrambler kugenzura
A) Gusobanura ihame rya 3W
Intera iri hagati yumurongo igomba kuba inshuro 3 ubugari bwumurongo. Kugirango ugabanye umuhanda hagati yumurongo, intera yumurongo igomba kuba nini bihagije. Niba intera hagati yumurongo itari munsi yinshuro 3 ubugari bwumurongo, 70% byumurima wamashanyarazi hagati yumurongo urashobora kubikwa nta nkomyi, ibyo bita itegeko rya 3W.
B) Kugenzura ibicuruzwa: CrossTalk bivuga kwivanga hagati yimiyoboro itandukanye kuri PCB iterwa no gukoresha insinga ndende, cyane cyane bitewe nigikorwa cyo gukwirakwiza ubushobozi no gukwirakwiza inductance hagati yumurongo ugereranije. Ingamba zingenzi zo gutsinda inzira nyabagendwa ni:
I. Ongera umwanya wa kabili ugereranije kandi ukurikize itegeko rya 3W;
Ii. Shyiramo insinga zo kwigunga hagati yinsinga zibangikanye
Iii. Mugabanye intera iri hagati ya cabling layer nindege yubutaka.
3. Amategeko rusange asabwa ibyifuzo
A) Icyerekezo cyindege yegeranye ni orthogonal. Irinde imirongo itandukanye yerekana ibimenyetso mubice byegeranye mu cyerekezo kimwe kugirango ugabanye guhuza intera bitari ngombwa; Niba ibi bintu bigoye kubyirinda bitewe nubushobozi bwibibaho (nkindege zimwe zinyuma), cyane cyane mugihe igipimo cyibimenyetso kiri hejuru, ugomba gutekereza gutandukanya ibice byinsinga kumurongo windege hamwe ninsinga zerekana hasi.
B) Gukoresha ibikoresho bito byihariye bigomba kuba bifitanye isano, kandi padi ya SMT iyobora hamwe nintera yegeranye igomba guhuzwa kuva hanze ya padi. Ihuza ritaziguye hagati ya padi ntabwo ryemewe.
C) Amategeko ntarengwa azenguruka, ni ukuvuga, agace k'umuzingi kagizwe n'umurongo w'ikimenyetso n'umuzenguruko wacyo bigomba kuba bito bishoboka. Gitoya agace kazengurutse, ntigabanye imishwarara yo hanze kandi ntoya yo kwivanga hanze.
D) insinga za STUB ntizemewe
E) Ubugari bwinsinga zurusobe rumwe bigomba guhora kimwe. Guhindagurika kwubugari bwinsinga bizatera impinganse iranga umurongo. Iyo umuvuduko wo kohereza ari mwinshi, gutekereza bizabaho. Mubihe bimwe, nkumuyoboro uhuza insinga, BGA pack yayobora insinga isa, kubera umwanya muto ntushobora kwirinda ihinduka ryubugari bwumurongo, ugomba kugerageza kugabanya uburebure bukomeye bwigice cyo hagati kidahuye.
F) Irinde insinga z'ibimenyetso gukora kwifata hagati yuburyo butandukanye. Ubwoko bwikibazo kiroroshye kugaragara mugushushanya ibyapa byinshi, kandi kwikorera-bizatera imirasire.
G) Inguni ikaze kandi Inguni iburyo igomba kwirindwaIgishushanyo cya PCB, bivamo imirasire idakenewe, hamwe nibikorwa byo gukoraPCBntabwo ari byiza.
