Mugushushanya kwa PCB, imiterere igira uruhare runini mugushushanya kimwe no gusaba ibicuruzwa.Intambwe yose yo gushushanya ikenera kwitabwaho no kwitabwaho kugirango ugere ku mikorere myiza.
Gukoresha inguni iburyo ni ibintu bigomba kwirindwa bishoboka mu nsinga za PCB, kandi byahindutse kimwe mu bipimo byo gupima ubwiza bw’insinga.None se ni bangahe insinga zinguni zifite ingaruka zo kohereza ibimenyetso?
Icya kabiri, ibiciro biratandukanye bitewe nuburyo butandukanye bwo gukora.
Uburyo butandukanye bwo gutanga umusaruro bivamo ibiciro bitandukanye.Nkibibaho bikozwe muri zahabu hamwe nu rubaho rwometseho amabati, imiterere ya maritike yo gukubita no gukubita, gukoresha imirongo ya silike yerekana imirongo hamwe nimirongo ya firime yumye bizatanga ibiciro bitandukanye, bivamo ibiciro bitandukanye.
Ihame, inzira yiburyo izahindura umurongo ubugari bwumurongo wohereza, bikaviramo guhagarara muri impedance.Mubyukuri, ntabwo ari inzira yiburyo gusa, ariko nanone inzira ityaye irashobora gutera impinduka.
Ingaruka z'imfuruka-iburyo ku kimenyetso zigaragarira cyane cyane mu bintu bitatu: icya mbere, imfuruka irashobora kuba ihwanye n'umutwaro wa capacitif ku murongo wohereza, ugabanya umuvuduko wo kuzamuka;icya kabiri, guhagarika inzitizi bizatera ibimenyetso byerekana;
Icya gatatu ni EMI ikorwa ninama yiburyo.Ubushobozi bwa parasitike buterwa nuburyo bwiburyo bwumurongo wogukwirakwiza bushobora kubarwa nuburyo bukurikira: C = 61W (Er) 1/2 / Z0 Muri formula yavuzwe haruguru, C bivuga ubushobozi bungana bwinguni (Igice: pF),
W bivuga ubugari bwikurikiranwa (unit: inch), εr bivuga dielectric ihoraho yikigereranyo, naho Z0 ni inzitizi iranga umurongo wohereza.
Mugihe ubugari bwumurongo wiburyo-buringaniye bwiyongera, impedance ngaho izagabanuka, bityo ibimenyetso bimwe byerekana ibimenyetso bizabaho.Turashobora kubara impedance ihwanye nyuma yubugari bwumurongo bwiyongereye ukurikije formula yo kubara impedance ivugwa mumutwe woherejwe.
Noneho ubare coefficient de coiffure ukurikije formulaire ifatika: ρ = (Zs-Z0) / (Zs + Z0).Mubisanzwe, impinduka ya impedance iterwa no gukoresha inguni iburyo iri hagati ya 7% na 20%, bityo coeffisente ntarengwa yo kwerekana ni 0.1.Shenzhen ANKE PCB Co, LTD
