Hano hari inyuguti nyinshi kurubaho rwa PCB, none niyihe mirimo ikomeye cyane mugihe cyanyuma?Inyuguti zisanzwe: "R" igereranya kurwanya, "C" igereranya ubushobozi, "RV" igereranya imbaraga zishobora guhinduka, "L" igereranya inductance, "Q" igereranya triode, "d" bivuze ko ari umuyoboro wa kabiri."X cyangwa Y" bisobanura kunyeganyega kristu, "U" bisobanura uruziga rwuzuye, nibindi.
Mubisanzwe, izindi nyuguti usibye umubare muto ugereranya moderi zimwe, nziza nibibi, inkingi yibigize, hamwe nagasanduku k'amatara ni agasanduku k'inyuguti.Muburyo bwo gushushanya no gukora, ugomba gusuzuma ubukana bwimiterere.Igishushanyo mbonera cyimiterere nibirango birasobanutse, kuburyo gukora bishobora kubyara inyuguti zisobanutse.Hano hari inyuguti zisobanutse kurubaho kugirango wirinde ibice byamakosa mugihe cyo gusudira no kuyitaho nyuma.
Igishushanyo mbonera kiranga ku kibaho cya PCB
01. Inomero yandika
Imikoreshereze yimibare icapura nimero ya nyuma yo guteranya ibice, cyane cyane inteko yinteko.Mubisanzwe, igishushanyo cyiteranirizo cya PCB gikoreshwa mubice bigize ibikoresho.ngombwa.
02. Ibimenyetso bya Polaris
Inyuma yumuriro wamashanyarazi, ibisobanuro bya polarite nicyerekezo cyumuyaga utemba mukuzunguruka.PCB ikubiyemo inyuguti ya polar igishushanyo ni ukwitondera electrode nziza kandi mbi.
03. Ikirangantego kimwe
Ibikoresho byuzuzanya byuzuye mubusanzwe bifite pin nyinshi, kandi ikirangantego kimwe cyibirenge nicyerekezo cyo gutandukanya ibikoresho.Niba PCB ipakira ipaki yimyenda idafite ikirangantego cyikirenge, cyangwa umwanya wikirangantego cyikirenge kimwe ntabwo ari bibi, bizatera ibice gukomera kunanirwa kurwanya ibicuruzwa.
Imiterere yimiterere inenge ku kibaho cya PCB
01. Umubare wa biti urimo
Inyuguti ziri mubikoresho byerekana imikoreshereze irashobora kubaho ko inyuguti zahagaritswe cyangwa zitwikiriwe nibigize.Bizatera ingorane mu gusudira guterana, kandi bizanatera ikibazo cyo gusana nyuma.
02. Umubare wumwanya uri kure cyane ya padi
Umubare wimibare ya kure ni kure cyane yibigize, bizatera umubare uhuye nimero iyo patch yateranijwe, kandi hashobora kubaho ibyago byo gusudira amakosa yibikoresho.
03. Pitzer ijambo ryuzuzanya
Guhuza cyangwa guhuzagurika byimyenda itandukanye yo gucapa bizatera icapiro rya silike guhinduka.Iyo guteranya ibice, ntibishobora gutandukanya ikibaho gipakira kijyanye nibigize.Hazabaho ibyago byo gusudira.
