Iyi ngingo iraguha intangiriro yuzuye kubisabwa na PCB yumuzunguruko wibisabwa hamwe nibyifuzo byo kuzigama ingufu.Kubera ko ikibazo cy’ingufu zikomeje kwiyongera ku isi no gushimangira amabwiriza y’ibidukikije, abakora PCB bashyize ahagaragara ibisabwa byinshi ku rwego rwo kuzigama ingufu z’ibikoresho.Guteka ninzira yingenzi mubikorwa bya PCB.Gusaba kenshi bitwara amashanyarazi menshi.Kubwibyo, kuzamura ibikoresho byo guteka kugirango bitezimbere kubungabunga ingufu byabaye bumwe muburyo bwo gukora ibicuruzwa byubuyobozi bwa PCB kuzigama ingufu no kugabanya ibiciro.
Igikorwa cyo guteka hafi ya yose ikora PCB yumuzunguruko.Ibikurikira bizakumenyesha uburyo bwo guteka ibisabwa kugirango umusaruro wa PCB wumuzunguruko.
1. Intambwe yuburyo bukenewe muguteka imbaho za PBC
1. Kumurika, kumurika, no kumera mugukora ibice byimbere bisaba kwinjira mucyumba cyo kumisha.
2. Kwibasira, gusya no gusya nyuma yo kumurika birasabwa gukuraho ubuhehere, ibishishwa hamwe nihungabana ryimbere, guhagarika imiterere no kongera imbaraga, kandi bisaba kuvura imigati.
3. Umuringa wibanze nyuma yo gucukura ugomba gutekwa kugirango uteze imbere amashanyarazi.
4. Mbere yo kuvura, kumurika, kwerekana no gutera imbere mubikorwa byo hanze byose bisaba ubushyuhe bwo guteka kugirango bitere imiti kugirango bitezimbere imikorere nibikorwa byo gutunganya.
5. Gucapa, mbere yo guteka, kwerekana, no kwiteza imbere mbere yo kugurisha ibicuruzwa bisaba guteka kugirango habeho ituze hamwe no gufatira hamwe ibikoresho byabigenewe.
6. Gutoragura no gucapa mbere yo gucapa inyandiko bisaba guteka kugirango uteze imbere imiti kandi itajegajega.
7. Guteka nyuma yo kuvura hejuru ya OSP ningirakamaro mugutuza no guhuza ibikoresho bya OSP.
8. Igomba gutekwa mbere yo kubumba kugirango yumishe ibikoresho, kunonosora hamwe nibindi bikoresho, kandi bigire ingaruka nziza.
9. Mbere yikizamini cyo kuguruka, kugirango wirinde ibyiza bitari byo no guca imanza zitari nziza ziterwa nubushuhe, biranasabwa gutunganya imigati.
10. Gufata imiti mbere yubugenzuzi bwa FQC ni ukurinda ubushuhe hejuru cyangwa imbere yubuyobozi bwa PCB kugirango ibisubizo byikizamini bidahwitse.
2. Gahunda yo guteka igabanijwemo ibyiciro bibiri: guteka ubushyuhe bwo hejuru no guteka ubushyuhe buke:
1. Ubushyuhe bwo hejuru bwo guteka bugenzurwa hafi 110°C, kandi igihe kimara ni amasaha 1.5-4;
2. Ubushyuhe buke bwo guteka bugenzurwa hafi 70°C, kandi igihe bimara ni amasaha 3-16.
3. Mugihe cyo gutekesha ikibaho cyumuzunguruko wa PCB, hagomba gukoreshwa ibikoresho bikurikira byo guteka no kumisha:
Ifuru ihanamye, izigama ingufu za tunnel, ibyuma byikora byuzuye byuzuza umurongo wo gutekesha imigati, ifuru ya infrarafarike hamwe nibindi bikoresho byacapwe bya PCB byumuzunguruko.
Uburyo butandukanye bwibikoresho bya feri ya PCB bikoreshwa muburyo butandukanye bwo guteka, nka: Gucomeka ku mbaho za PCB, kugurisha imashini ya mask yo gucapa, bisaba ibikorwa binini byikora.Amashyiga azigama ingufu zikozwe mu ziko akenshi akoreshwa mu kuzigama imbaraga nyinshi nubutunzi mugihe bigerwaho neza.Igikorwa cyiza cyo guteka, gukora neza cyane nubushyuhe bwo gukoresha ingufu, mubukungu no kubungabunga ibidukikije, bikoreshwa cyane mubikorwa byubuyobozi bwumuzunguruko kubagurisha mask mbere yo guteka hamwe ninyandiko nyuma yo guteka kubibaho bya PCB;icya kabiri, ikoreshwa cyane muguteka no gukama kubutaka bwa PCB hamwe nihungabana ryimbere.Ni itanura rishyushye ryumuyaga uhuha hamwe nibikoresho bigabanutse, ikirenge gito kandi gikwiriye gutekwa byoroshye.
4. PCB yumuzunguruko wibikoresho byo guteka, ibyifuzo bya feri:
Mu ncamake, ni inzira byanze bikunze abahinguzi b'umuzunguruko wa PCB bafite byinshi bisabwa kandi byinshi murwego rwo kuzigama ingufu.Nicyerekezo cyingenzi cyane cyo kuzamura urwego rwo kuzigama ingufu, kuzigama ibiciro no kuzamura umusaruro binyuze mukuzamura cyangwa gusimbuza ibikoresho byo guteka.Amashyiga azigama ingufu zikozwe mu ziko afite ibyiza byo kuzigama ingufu, kurengera ibidukikije, no gukora neza, kandi ubu arakoreshwa cyane.Icya kabiri, amashyiga yumuriro ashyushye afite ibyiza byihariye mubibaho byohejuru bya PCB bisaba guteka neza kandi bisukuye nkibibaho bitwara IC.Byongeye kandi, bafite imirase ya infragre.Amatanura ya tunnel hamwe nibindi bikoresho bya feri kuri ubu birasa no gukama no gukiza ibisubizo.
Nkumuyobozi mu kubungabunga ingufu, Xinjinhui akomeje guhanga udushya no gukora impinduramatwara ikora neza.Mu mwaka wa 2013, isosiyete yashyize ahagaragara ibisekuru bya mbere PCB yanditse nyuma yo guteka ubwoko bwa ecran icapura ifuru ya tunnel, yazamuye imikorere yo kuzigama ingufu 20% ugereranije nibikoresho gakondo.Muri 2018, uruganda rwatangije igisekuru cya kabiri PCB yanditse nyuma yo guteka itanura rya tunnel, ryageze ku ntera ya 35% mu kuzigama ingufu ugereranije n’ibisekuru bya mbere.Mu 2023, hamwe nubushakashatsi bunoze hamwe niterambere ryibintu byinshi byavumbuwe hamwe nikoranabuhanga rishya, urwego rwo kuzigama ingufu rwikigo rwiyongereye kugera kuri 55% ugereranije nabasekuruza ba mbere, kandi rutoneshwa namasosiyete 100 akomeye muri PCB inganda, harimo na Jingwang Electronics.Izi sosiyete zatumiwe na Xin Jinhui gusura no kuvugana ninama zipima uruganda.Mu bihe biri imbere, Xinjinhui azanashyira ahagaragara ibikoresho byinshi byikoranabuhanga.Nyamuneka komeza ukurikirane, kandi urahawe ikaze kuduhamagarira kugisha inama no gukora gahunda yo kudusura kugirango tuvugane imbonankubone.
