PCB iperereza nuburyo bwo guhuza ibizamini byamashanyarazi, nikintu cyingenzi cya elegitoronike kandi gitwara guhuza no kuyobora ibikoresho bya elegitoroniki.Ubushakashatsi bwa PCB bukoreshwa cyane mugupima amakuru no guhuza amakuru ya PCBA.Amakuru yimikorere yimikorere ya probe arashobora gukoreshwa muguhitamo niba ibicuruzwa bihuye bisanzwe kandi niba amakuru yibikorwa ari ibisanzwe.
Mubisanzwe, iperereza rya PCB rifite ibisobanuro byinshi, bigizwe ahanini nibice bitatu: icya mbere, umuyoboro w'urushinge, ugizwe ahanini n'umuringa wumuringa kandi ushyizwemo zahabu.Iya kabiri ni isoko, cyane cyane insinga zicyuma cya piyano nicyuma cyamasoko cyometseho zahabu.Iya gatatu ni urushinge, cyane cyane ibyuma (SK) nikel isahani cyangwa isahani ya zahabu.Ibice bitatu byavuzwe haruguru byakusanyirijwe hamwe.Mubyongeyeho, hari amaboko yo hanze, ashobora guhuzwa no gusudira.
Ubwoko bwa PCB
1. Ubushakashatsi bwa ICT
Umwanya ukunze gukoreshwa ni 1.27mm, 1.91MM, 2.54mm.Urukurikirane rusanzwe ni urukurikirane 100, urukurikirane 75, hamwe na 50.Zikoreshwa cyane cyane mugupima inzitizi kumurongo no kugerageza imikorere.Ikizamini cya ICT hamwe na FCT ikoreshwa kenshi mugupima imbaho za PCB.
2. Ubushakashatsi bubiri bwarangiye
Ikoreshwa mugupima BGA.Biragoye cyane kandi bisaba gukora cyane.Mubisanzwe, terefone igendanwa IC chip, mudasobwa igendanwa ya mudasobwa, mudasobwa ya tablet na chip ya IC itumanaho.Umurambararo wumubiri wa inshinge uri hagati ya 0.25MM na 0.58MM.
3. Hindura iperereza
Ihinduramiterere imwe ifite imirongo ibiri yumurongo kugirango igenzure bisanzwe bifungura kandi bisanzwe bifunze imikorere yumuzunguruko.
4. Iperereza ryinshi
Ikoreshwa mugupima ibimenyetso byumuvuduko mwinshi, hamwe nimpeta ikingira, irashobora kugeragezwa muri 10GHz na 500MHz idafite impeta ikingira.
5. Inzira ya rotary
Ubusanzwe elastique ntabwo iri hejuru, kuko kwinjira kwayo birakomeye, kandi mubisanzwe bikoreshwa mugupima PCBA byakozwe na OSP.
6. Iperereza ryinshi
Diameter ya probe iri hagati ya mm 2,98 na 5.0 mm, kandi ikizamini ntarengwa gishobora kugera kuri 50 A.
7. Ubushakashatsi bwa bateri
Mubisanzwe bikoreshwa mugutezimbere ingaruka zifatika, hamwe no guhagarara neza hamwe nubuzima burebure.Ikoreshwa mugutwara amashanyarazi mugice cyo guhuza bateri ya terefone igendanwa, ikarita ya SIM ikarita yerekana ikarita hamwe nigice cyitwara gikunze gukoreshwa mumashanyarazi.
