Mu iyubakwa ryuzuye ryibikoresho bya elegitoroniki bigezweho, ikibaho cyacapwe cya PCB gifite uruhare runini, kandi Urutoki rwa Zahabu, nkigice cyingenzi cyihuza ryizewe cyane, ubwiza bwubuso bwabwo bugira ingaruka kumikorere no mubuzima bwa serivisi.
Urutoki rwa zahabu bivuga umurongo wa zahabu uhuza inkombe ya PCB, ikoreshwa cyane mugushiraho amashanyarazi ahamye hamwe nibindi bikoresho bya elegitoronike (nka memoire na kibaho, ikarita yubushushanyo hamwe ninteruro yakira, nibindi). Bitewe n’amashanyarazi meza cyane, irwanya ruswa kandi irwanya itumanaho rito, zahabu ikoreshwa cyane mubice nkibi bihuza bisaba kwinjiza kenshi no kuyikuraho no gukomeza umutekano muremure.
Isahani ya zahabu ingaruka mbi
Kugabanuka k'umuriro w'amashanyarazi: Ubuso bukabije bw'urutoki rwa zahabu bizongera imbaraga zo guhangana, bikavamo kwiyongera kwerekanwa mu bimenyetso, bishobora gutera amakosa yo kohereza amakuru cyangwa guhuza bidahwitse.
Kugabanya kuramba: Ubuso butoroshye biroroshye kwegeranya umukungugu na okiside, byihutisha kwambara kwizahabu kandi bikagabanya ubuzima bwurutoki rwa zahabu.
Ibikoresho byangiritse byangiritse: Ubuso butaringaniye burashobora gushushanya aho uhurira nundi muburanyi mugihe cyo kwinjiza no kuwukuraho, bikagira ingaruka ku gukomera kwihuza hagati yimpande zombi, kandi bishobora gutera kwinjiza bisanzwe cyangwa kuvanwaho.
Kugabanuka kwiza: nubwo iki atari ikibazo kiziguye cyimikorere ya tekiniki, isura yibicuruzwa nayo ni ikintu cyingenzi cyerekana ubuziranenge, kandi isahani ya zahabu itajenjetse izagira ingaruka ku isuzuma rusange ryibicuruzwa.
Urwego rwemewe
Ubunini bwa zahabu: Muri rusange, uburebure bwa zahabu yerekana urutoki rwa zahabu burasabwa kuba hagati ya 0.125 mm na 5.0μm, agaciro kihariye gashingiye kubikenewe no gutekereza kubiciro. Kinini cyane biroroshye kwambara, umubyimba mwinshi uhenze cyane.
Ubuso bwubuso: Ra (arithmetic mean roughness) ikoreshwa nkigipimo cyo gupima, kandi ibisanzwe byakira ni Ra≤0.10μm. Ibipimo ngenderwaho byemeza neza amashanyarazi no kuramba.
Ipfundikanya imwe: Igice cya zahabu kigomba gutwikirwa kimwe nta kibanza kigaragara, umuringa ugaragara cyangwa ibibyimba kugirango harebwe imikorere ihamye ya buri ngingo.
Ubushobozi bwo gusudira no kwangirika kwangirika: ikizamini cyo gutera umunyu, ubushyuhe bwo hejuru hamwe nubushuhe buhebuje hamwe nubundi buryo bwo gupima ruswa no kwizerwa kuramba kurutoki rwa zahabu.
Ububiko bwa zahabu bwuzuye urutoki rwa PCB PCB bifitanye isano itaziguye no guhuza kwizerwa, ubuzima bwa serivisi no guhatanira isoko ibicuruzwa bya elegitoroniki. Gukurikiza amahame akomeye yinganda nubuyobozi bwo kwemerwa, hamwe no gukoresha uburyo bwiza bwo gutunganya zahabu nziza ni urufunguzo rwo kwemeza imikorere no kunyurwa kwabakoresha.
Hamwe n’iterambere ry’ikoranabuhanga, inganda zikora ibikoresho bya elegitoroniki nazo zihora zishakisha ubundi buryo bunoze, butangiza ibidukikije ndetse n’ubukungu bwometseho zahabu kugira ngo bwuzuze ibisabwa by’ibikoresho bya elegitoroniki bizaza.
