Mu isi y’ibikoresho by’ikoranabuhanga, ibyuma bicukurwaho (PCBs) ni ibintu by’ingenzi bikora nk’inkingi y’ibikoresho byinshi by’ikoranabuhanga. Uburyo bwo gukora ibi bikoresho bigoye bugira intambwe nyinshi, imwe muri zo ikaba ari ugucukura. Guhitamo icyuma gicukurwaho neza ni ingenzi kugira ngo wongere imikorere myiza kandi urebe neza ko umusaruro wa nyuma umeze neza. Iyi nkuru izagufasha kumenya ibintu by’ingenzi ugomba kuzirikana mu gihe uhitamo icyuma gicukurwaho cya PCB gikwiranye n’ibyo ukeneye mu gucukura ibyuma.
IBINTU BY'INGENZI BYO GUHITAMO
1. Ingano y'agace k'imashini yo gucukura: Ingano y'agace k'imashini yo gucukura ni ingenzi cyane. Igomba kuba ijyanye n'ibipimo by'igice gishyirwa kuri PCB. Ingano zisanzwe ziri hagati ya mm 0.2 na mm 3.2, ariko ingano zihariye nazo ziraboneka ku bikorwa byihariye.
2. Guhuza ibikoresho: Ibikoresho bitandukanye bya PCB bisaba uduce dutandukanye two gucukura. Urugero, ibikoresho bikonjeshejwe n'ibirahure nka FR-4 bishobora gusaba agace gakomeye ko gucukura karibide, mu gihe ibikoresho byoroshye bishobora gucukurwa hakoreshejwe agace gacukura ka HSS.
3. Umuvuduko wo gucukura: Umuvuduko wo gucukura ugira ingaruka ku bwiza bw'umwobo wacukuwe. Umuvuduko wihuta uba mwiza kurushaho, ariko ushobora no kongera ibyago byo kwangiza PCB. Ni ngombwa gushaka uburinganire bujyanye n'ibyo ukeneye mu gucukura.
4. Gukonjesha no Gusiga Amavuta: Gucukura bitanga ubushyuhe, bishobora kwangiza agace k'imashini yo gucukura na PCB. Gukoresha sisitemu yo gukonjesha cyangwa amavuta bishobora gufasha mu kubungabunga ubushyuhe bwiza no kongera igihe cy'imashini yo gucukura.
5. Ikiguzi ugereranyije n'ubwiza: Nubwo bishobora gukurura guhitamo uburyo buhendutse, gushora imari mu bwizaUduce two gucukura uduce twa PCBbishobora kugufasha kuzigama amafaranga mu gihe kirekire. Uduce two gucukura two mu bwoko bwa drill tworoshye tugabanya ibyago byo kwangirika kandi bigatuma imyobo isukuye, bigatuma habaho inenge nke mu gicuruzwa cya nyuma.
Mu gusoza
Guhitamo icapiro ryiza kurusha ayandiimyitozo yo gucukura uruzigabit ni intambwe y'ingenzi mu gikorwa cyo gukora PCB. Mu gusobanukirwa ubwoko bw'uduce two gucukura duhari no gusuzuma ibintu nk'ingano, uburinganire bw'ibikoresho, n'umuvuduko wo gucukura, ushobora kongera imikorere no kwemeza ko umusaruro mwiza uzavamo. Waba uri umuntu ukunda ibintu byinshi cyangwa umunyamwuga mu nganda z'ibikoresho by'ikoranabuhanga, guhitamo neza uduce two gucukura dukoresha ikoranabuhanga bizamura imikorere n'ubwizerwe bw'ibikoresho byawe by'ikoranabuhanga.
