Mu gishushanyo mbonera cya PCB, imiterere yibigize ni ingenzi, igena urwego rwiza kandi rwiza rwibibaho n'uburebure n'ubwinshi bw'insinga zacapwe, kandi bigira ingaruka runaka ku kwizerwa kwa mashini yose.
Ikibaho cyiza cyumuzunguruko, usibye no gusohoza ihame ryimikorere, ariko nanone gutekereza kuri EMI, EMC, ESD (gusohora amashanyarazi), ubudahangarwa bwibimenyetso nibindi biranga amashanyarazi, ariko nanone ukareba imiterere yubukanishi, ubushyuhe bunini bwa chip power ibibazo byo gutandukana.
Ibisobanuro rusange bya PCB ibisabwa
1, soma igishushanyo mbonera cyerekana ibisobanuro, wuzuze imiterere yihariye, module idasanzwe nibindi bisabwa.
2, shiraho imiterere ya grid point kuri 25mil, irashobora guhuzwa unyuze kuri gride point, intera ingana;Uburyo bwo guhuza ni bunini mbere ntoya (ibikoresho binini nibikoresho binini bihujwe mbere), kandi uburyo bwo guhuza ni hagati, nkuko bigaragara ku gishushanyo gikurikira
3, wuzuze ahantu habujijwe uburebure burebure, imiterere nuburyo bwihariye bwibikoresho, ibisabwa ahantu bibujijwe.
① Igishushanyo 1 (ibumoso) hepfo: Ibipimo ntarengwa bisabwa, byerekanwe neza murwego rwa mashini cyangwa ikimenyetso cyerekana, byoroshye kubisuzuma nyuma;
.
Imiterere yimiterere nibikoresho byihariye birashobora guhagarikwa neza na coordinateur cyangwa na coordinate yikintu cyo hanze cyangwa umurongo wo hagati wibigize.
4, imiterere igomba kubanza kubanziriza imiterere, ntubone ikibaho kugirango utangire imiterere itaziguye, ibanzirizasuzuma irashobora gushingira kumyitozo ya module, mubuyobozi bwa PCB gushushanya umurongo wibimenyetso byerekana umurongo, hanyuma bigashingira. ku isesengura ryerekana ibimenyetso, mubuyobozi bwa PCB gushushanya umurongo wumufasha wumurongo, suzuma umwanya ugereranije wa module muri PCB nubunini bwakazi.Shushanya umurongo wubufasha wubugari bwa 40mil, hanyuma usuzume gushyira mu gaciro imiterere hagati ya module na module ukoresheje ibikorwa byavuzwe haruguru, nkuko bigaragara ku gishushanyo gikurikira.
5, imiterere ikeneye gusuzuma umuyoboro uva kumurongo wamashanyarazi, ntugomba gukomera cyane, binyuze muri gahunda yo kumenya aho ingufu zituruka aho zijya, guhuza igiti cyamashanyarazi
6, ibice byubushyuhe (nka capacitori ya electrolytike, oscillator ya kristu) bigomba kuba kure yumuriro wamashanyarazi nibindi bikoresho byo hejuru cyane, bishoboka cyane mumashanyarazi yo hejuru
7, kugirango uhuze ibyiyumvo bitandukanye byerekana itandukaniro, imiterere yimiterere yubuyobozi, ikibaho cyose cyateganijwe
Ibimenyetso byumuvuduko mwinshi hamwe nibisanzwe-bitandukanijwe rwose nibimenyetso bidakomeye byumuyaga muto na voltage nkeya.Ibice bya voltage ndende bifunitse mubice byose nta muringa wongeyeho.Intera yikurikiranya hagati yumuriro mwinshi wa voltage irasuzumwa ukurikije imbonerahamwe isanzwe
Ikimenyetso kigereranya gitandukanijwe nicyapa cya digitale hamwe nubugari bwagabanijwe byibura 20mil, kandi analog na RF bitunganijwe muburyo bwa '-' imyandikire cyangwa 'L' ukurikije ibisabwa mubishushanyo mbonera.
Ikimenyetso kinini cyane gitandukanijwe nikimenyetso gito, intera yo gutandukana byibuze 3mm, kandi imiterere yumusaraba ntishobora kwizerwa
Imiterere yibikoresho byingenzi byerekana ibimenyetso nka kristu oscillator hamwe nuwashoferi wamasaha bigomba kuba kure yimiterere yumuzunguruko, ntabwo biri kumpera yikibaho, kandi byibura 10mm uvuye kuruhande rwibibaho.Oscillator ya kristu na kirisiti igomba gushyirwa hafi ya chip, igashyirwa murwego rumwe, ntukubite umwobo, hamwe n'umwanya wabitswe kubutaka
Inzira imwe yumuzunguruko ifata imiterere "isanzwe" (kongera gukoresha module imwe) kugirango ihuze ibimenyetso
Nyuma yo gushushanya PCB, tugomba gukora isesengura no kugenzura kugirango umusaruro urusheho kugenda neza.
