Hariho uturere twinshi muriIgishushanyo cya PCBaho hagomba gutekerezwa umwanya utekanye. Hano, yashyizwe mubice by'agateganyo mu byiciro bibiri: kimwe ni umwanya w’umutekano ujyanye n’amashanyarazi, ikindi ni umwanya w’umutekano udafite amashanyarazi.
Umwanya ujyanye n'amashanyarazi
1. Gutandukanya insinga
Kubijyanye nubushobozi bwo gutunganya inzira nyamukuruAbakora PCBbireba, intera ntarengwa hagati yinsinga ntishobora kuba munsi ya 4mil. Intera ntarengwa ya wire nayo ni intera kuva kuri wire kugera kuri wire na wire kugeza padi. Uhereye ku musaruro, nini nini niba bishoboka, na 10mil nimwe isanzwe.
2.Pad aperture n'ubugari bwa padi
Kubijyanye nubushobozi bwo gutunganya ibicuruzwa bikuru bya PCB, aperture ya padi ntigomba kuba munsi ya 0.2mm niba yacukuwe mumashini, na 4mil niba ari lazeri. Kwihanganira aperture biratandukanye gato ukurikije isahani, mubisanzwe birashobora kugenzurwa muri 0.05mm, ubugari ntarengwa bwa padi ntibugomba kuba munsi ya 0.2mm.
3. Gutandukanya padi
Kubijyanye nubushobozi bwo gutunganya ibicuruzwa bikuru bya PCB, intera iri hagati yipaki ntishobora kuba munsi ya 0.2mm.
4. Intera iri hagati yumuringa nisahani
Umwanya uri hagati yimpu zumuringa zishyizwe hamwe nuruhande rwaUbuyobozi bwa PCBntigomba kuba munsi ya 0.3mm. Ku gishushanyo-Amategeko-Urupapuro rwerekana urutonde, shiraho amategeko yumwanya kuri iki kintu.
Niba ahantu hanini h'umuringa hashyizweho, mubusanzwe hariho intera yo kugabanuka hagati yisahani ninkombe, ubusanzwe ikaba yashyizwe kuri 20mil. Mu nganda za PCB n’inganda zikora, mubihe bisanzwe, bitewe nuburyo bwa tekinike bwikibaho cyumuzunguruko cyarangiye, cyangwa kwirinda uruhu rwumuringa rugaragara kumpera yikibaho bishobora gutera uruziga cyangwa amashanyarazi magufi, injeniyeri zizakwirakwiza a ahantu hanini h'umuringa ugereranije nuruhande rwibibaho bigabanuka 20mil, aho kuba uruhu rwumuringa rwakwirakwijwe kumpera yikibaho.
Uku kwerekana umuringa kurashobora gukemurwa muburyo butandukanye, nko gushushanya igipande cyizamu ku nkombe yisahani, hanyuma ugashyiraho intera iri hagati yumuringa no kubika. Uburyo bworoshye bwatangijwe hano, ni ukuvuga, intera zitandukanye z'umutekano zashyizweho kubintu bikozwe mu muringa. Kurugero, intera yumutekano yibibaho byose yashyizwe kuri 10mil, naho umuringa ugashyirwa kuri 20mil, ibyo bikaba bishobora kugera ku ngaruka zo kugabanuka 20mil imbere yurubaho kandi bikuraho umuringa ushobora kuba wapfuye mugikoresho.
Umwanya wumutekano udafite amashanyarazi
1. Ubugari bw'imiterere, uburebure n'umwanya
Nta gihinduka gishobora gukorwa mugutunganya firime yinyandiko, ariko ubugari bwimirongo yinyuguti ziri munsi ya 0.22mm (8.66mil) muri D-CODE bugomba gushirwa kuri 0.22mm, ni ukuvuga ubugari bwimirongo ya inyuguti L = 0.22mm (8.66mil).
Ubugari bwimiterere yose ni W = 1.0mm, uburebure bwimiterere yose ni H = 1,2mm, naho intera iri hagati yinyuguti ni D = 0.2mm. Mugihe inyandiko iri munsi yurwego rwo hejuru, gutunganya icapiro bizahinduka.
2. Gutandukanya Vias
Umuhengeri (VIA) kugeza unyuze mu mwobo (inkombe kugera ku nkombe) ugomba kuba mwiza kuruta 8mil
3.Kutandukana kuva icapiro rya ecran kugeza padi
Gucapisha ecran ntabwo byemewe gupfuka padi. Kuberako niba ecran ya ecran itwikiriwe nuwagurishije, icapiro rya ecran ntirizaba kumabati mugihe amabati arimo, bizagira ingaruka kumikorere. Uruganda rusanzwe rusaba ko umwanya wa 8mil wabikwa. Niba ikibaho cya PCB kigarukira mukarere, intera ya 4mil iremewe. Niba icapiro rya ecran ryarengewe kubwimpanuka mugihe cyo gushushanya, uruganda rwamasahani ruzahita rukuraho icapiro rya ecran kuri padi mugihe cyo gukora kugirango barebe amabati kuri padi.
Birumvikana, ni uburyo-buri-buryo mugihe cyagenwe. Rimwe na rimwe, icapiro rya ecran ribikwa nkana hafi ya padi, kubera ko iyo amakariso abiri yegeranye, icapiro rya ecran hagati rishobora gukumira neza abagurisha imiyoboro migufi mugihe cyo gusudira, nikindi kibazo.
4.Uburebure bwa mashini ya 3D hamwe n'umwanya utambitse
Mugihe ushyira ibice kuriPCB, ni ngombwa gusuzuma niba icyerekezo gitambitse hamwe nuburebure bwumwanya bizavuguruzanya nizindi mashini. Kubwibyo, mugushushanya, dukwiye gusuzuma byimazeyo guhuza ibice, hagati yibicuruzwa byarangiye PCB nibicuruzwa, hamwe nuburyo butandukanye, hamwe no kubika umwanya utekanye kuri buri kintu cyerekanwe kugirango tumenye ko nta makimbirane mu kirere.
