Mugihe ingano yibigize PCBA ibona bito kandi bito, ubucucike burenze hejuru kandi hejuru; Uburebure hagati y'ibikoresho n'ibikoresho (Ikibanza / Kureka Kuri PCB na PCB) biragenda no kwiyongera no kwiyongera, bityo tugashyira imbere ibintu byinshi kuri kwizerwa mu bicuruzwa bya elegitoroniki PCBA.
Ibigize PCBA bivuye muri binini kugeza mato, uhereye kuri gake kugirango duhindure inzira
Impamvu y'ibidukikije n'ingaruka zabo
Impamvu zisanzwe zishingiye ku bidukikije nko kuba ubushuhe, umukungugu, spray, ibumba, nibindi, bitera ibibazo bitandukanye bya kunanirwa kwa PCBA
Ubushuhe mu bidukikije byo hanze by'ibice bya elegitoronike bya PCB, hafi ya byose hari ibyago byo kugandukira kuneka byinshi, molekile y'amazi ni ntoya ihagije kugirango igere ku gitsina gare. Iyo ikirere kigeze aho ubushuhe runaka, gishobora gutera abimukira bya electrochemical, ibisimba byongeye kugoreka mu muzunguruko wo hejuru.
Inteko ya PCba | Gutunganya ibishushanyo | Iturura ryumuzunguruko ritunganya ibicuruzwa | oem Electronic Inteko elegitoroniki | Gutunganya umuzunguruko Gutunganya - Ikoranabuhanga rya Elegitoroniki
Imyuka / ubushuhe + ionic yanduye ionic (umunyu, flux abakozi bakora
Iyo RH mu kirere igera kuri 80%, hazabaho molekile 5 kugeza kuri 20 z'ubugari, molekile zose zirashobora kwimuka mu bwisanzure, iyo hari karubone, ishobora gutanga reaction ya electrochemical; Iyo Rh igera kuri 60%, urwego rwo hejuru rwibikoresho ruzakora film y'amazi hamwe nubwinshi bwa molekile 2 kugeza kuri 4, kandi imiti izabaho mugihe umwanda washonze. Iyo RH <20% mu kirere, hafi ya peronomena ya peronomena;
Kubwibyo, kurinda ubushuhe nikintu cyingenzi cyo kurinda ibicuruzwa.
Kubikoresho bya elegitoroniki, ubushuhe buza muburyo butatu: imvura, ubutwenge, numwuka wamazi. Amazi ni electrolyte ishobora gushonga ibintu byinshi byangiza ibigori bya corode. Iyo ubushyuhe bwigice runaka cyibikoresho biri munsi ya "ikime" (ubushyuhe), hazabaho citonsation hejuru: ibice byubatswe cyangwa pcba.
umukungugu
Hariho umukungugu mukirere, kandi umukungugu wa adsorbs ion pollutants kugirango ituze mubikorwa ibikoresho bya elegitoroniki kandi bigatera kunanirwa. Nibintu bisanzwe byatsinzwe na elegitoroniki murwego.
Umukungugu ugabanijwemo ubwoko bubiri: Umukungugu uri Coarse ni ibice bidasanzwe hamwe na diameter ya 2,5 kugeza 15, muri rusange ntabwo bitera ibibazo nko gutsindwa, ahubwo bigira ingaruka kumiti ihuza; Umukungugu mwiza ni ibice bidasanzwe hamwe na diameter munsi ya mikorobe 2.5. Umukungugu mwiza ufite umukungugu runaka kuri PCBA (Veneer) kandi urashobora gukurwaho no gukaraba anti-status.
Ibyago by'umukungugu: a. Kubera umukungugu utura hejuru ya PCBA, ruswa ya elecrochemike, kandi igipimo cyo kunanirwa; b. Umukungugu + ubushyuhe bukabije + spray yumunyu ifite ibyangiritse cyane kuri PCBA, hamwe nibikoresho bya elegitoronike ni byinshi mu nkombe z'inyanja, ubutayu.
Kubwibyo, kurinda umukungugu nigice cyingenzi cyo kurengera ibicuruzwa.
Spray yumunyu
Imiterere ya spray yumunyu: Spray yumunyu iterwa nibintu bisanzwe nkumuraba, imiraba nubusambanyi (inkuta zacyo bivuye ku nkombe, kandi izuba riva mu nkombe ni 1% by'inkombe (ariko inkubi y'umuyaga izaturika).
Ikigigo cya spray yumunyu: a. kwangiza gutwika ibice by'ibyuma; b. Igipimo cya electrochemicokeri yihuse igipimo cyo gutandukana kw'icyuma no kunanirwa.
AMASOKO ISANZWE: a. Hano hari umunyu, Ure, aside lactique hamwe nindi miti iri mu icyuya kimwe cyibikoresho bya elegitoroniki nkumunyu, gants igomba gusambana mugihe cyo guterana cyangwa gukoresha, kandi igikombe ntigomba gukorwaho, b. Hano hari abashimusi na aside muri flux, bigomba gusukurwa no kwibanda kwayo ku isi.
Kubwibyo, gukumira umunyu nigice cyingenzi cyo kurinda ibicuruzwa.
ubumuga
Reliew, izina Rusange rya Filamentous Fungi, risobanura "Moldy Fungi," ukunda gushinga ubuzima bwiza, ariko ntukare imibiri nini nk'ibihumyo. Ahantu hishuwe kandi ususurutse, ibintu byinshi bikura fluff bigaragara, ibirungo cyangwa ibisuguti, bibumba.
PCB Mold Phenomen
Ingaruka z'ibumba: a. Mold Phogocytose no Kwamamaza bituma habaho ibijyanye nibikoresho kama kugabanuka, kwangiza no gutsindwa; b. Metabolites yubutaka ni acide kama, zigira ingaruka kumashanyarazi no kurwanya amashanyarazi no gutanga ARC.

Kubwibyo, kurwanya ubumuga nigice cyingenzi cyo kurengera ibicuruzwa.
Urebye ibintu byavuzwe haruguru, kwizerwa kw'ibicuruzwa bigomba kuba byemejwe neza, kandi bigomba kwigunga bituruka ku bidukikije bikomokaho bishoboka, bityo inzira yo gutora imiterere itangira.
Nyuma yo gupakira bya PCB, ingaruka zo kurasa munsi yitara ryumutuku, igifu cyumwimerere nacyo gishobora kuba cyiza!
Gutinda bitatu byo kurwanya irangi bivuga hejuru ya PCB igice cyoroshye cyo kurinda urwego, ni ukumenyekanisha hejuru-gusudira hejuru yubuso, bizwi cyane kugirango bitwikire hejuru, bifatanye (izina ryicyongereza (guhuza izina). Ikunda ibintu bya elegitoroniki byoroshye mubidukikije bikaze, kunoza cyane umutekano no kwizerwa nibicuruzwa bya elegitoroniki no kwagura ubuzima bwibicuruzwa. IHURIRO RY'INGENDINDA RIREMEZA KURINDA RUGENDE / IGICE RY'IBIKORWA BY'IBIDUKIKI N'UBUNTU, BYIZA, SHOCK, Guhungabana, Guhungabana, Gutongana
Nyuma yo gupakira, PCB ikora firime yo gukingira mu mucyo hejuru, ishobora kubuza neza amasaro yamazi nubushuhe, irinde kumeneka numuzunguruko mugufi.
