1. Iyo biteye ubwoba-ingano nini ya PCB, koresha gahunda yo kwizirika. Birasabwa ko umubare ntarengwa wigice udakwiye kurenga ibice 30. Ikata igomba gukingurwa mugihe cyiminota 10 nyuma yo guteka kugirango usohoke PCB hanyuma ubishyireho neza kugirango ukonje. Nyuma yo guteka, bigomba gukanda. Kugoreka. Ibinini binini bya PCB ntibisabwa guteka koga, nkuko byoroshye kunama.

2. Mugihe uteka amakoni mato na make, urashobora gukoresha stacking. Umubare ntarengwa wikimenyetso ntirusabwa kurenga ibice 40, cyangwa birashobora kuba umukiranutsi, kandi umubare ntabwo ugarukira. Ugomba gufungura itanura hanyuma ugakuramo PCB muminota 10 yo guteka. Emera gukonja, hanyuma ukande JIG arwanya antina nyuma yo guteka.

Ingamba iyo PCB ishobora guteka

1. Ubushyuhe bworoshye ntibugomba kurenza TG ingingo ya PCB, kandi ibisabwa muri rusange ntibigomba kurenga 125 ° c. Mu minsi ya mbere, ingingo ya TG yaba irimo Macbs zimwe zirimo hasi cyane, none TG ya PCB-yubusa ahanini iri hejuru ya 150 ° C.

2. PCB yatetse igomba gukoreshwa vuba bishoboka. Niba bidakoreshejwe, bigomba kuba vacuum bihuta vuba bishoboka. Niba uhuye namahugurwa igihe kirekire, bigomba kongera gutekwa.

3. Ibuka kwishyiriraho ibikoresho byumisha ibikoresho mu gitako, bitabaye ibyo, imashini izaguma mu kigero kandi ikongerera ubushuhe bwayo, atari byiza kuri PCB dehumidimetic.

4. Duhereye ku bwiza, umusirikare mushya wa PCB ikoreshwa, ibyiza bizaba. Nubwo PCB yarangiye ikoreshwa nyuma yo guteka, haracyari ibyago runaka.

Ibyifuzo bya PCB Guteka
1. Birasabwa gukoresha ubushyuhe bwa 105 ± 5 ℃ guteka PCB. Kuberako ingingo zibi zibi ni 100 ℃, igihe cyose kirenze ingingo yo kubira, amazi azahinduka steam. Kuberako PCB idakubiyemo molekile nyinshi zamazi, ntibisaba ubushyuhe bwinshi bwo kongera igipimo cyumwuka.

Niba ubushyuhe ari hejuru cyane cyangwa igipimo cyo kugabana ni cyihuta cyane, bizaroroshye gutuma umwuka wamazi waguka vuba, mubyukuri atari byiza kubwiza. By'umwihariko ku mbaho ​​nyinshi na PCB hamwe n'imyobo yashyinguwe, 105 ° C iri hejuru y'amazi ateka, kandi ubushyuhe ntibuzabura cyane. , Irashobora gutesha agaciro no kugabanya ibyago byo kurira. Byongeye kandi, ubushobozi bwitanura buriho bwo kugenzura ubushyuhe bwateye imbere cyane kuruta mbere.

2. Niba PCB igomba gutekwa biterwa no kuba ibipfunyiko byayo bitose, ni ukuvuga kubona ikarita ya Hic (desidenity) muri paki ya vacuum yerekanye ubushuhe. Niba ibipakira ari byiza, hic ntabwo byerekana ko ubushuhe mubyukuri ushobora kugenda kumurongo udatekanye.

3. Birasabwa gukoresha "igororotse" na Spand Baking mugihe PCB Guteka, kuko ibi birashobora kugera ku ngaruka nini zo guhagarikwa ikirere gishyushye, kandi ubushuhe biroroshye kuvanwa muri PCB. Ariko, kuri PCB nini nini, birashobora kuba ngombwa gusuzuma niba ubwoko buhagaritse buzatera kunama no guhindura Inama y'Ubutegetsi.

4. Nyuma ya PCB yatetse, birasabwa kubishyira ahantu humye kandi bituma ukonje vuba. Nibyiza gukanda ikigo "kirwanya ku nzuka kigana hejuru yinama, kubera ko ikintu rusange kiroroshye gukurura imyuka y'amazi kuva aho bishyuha. Ariko, gukonjesha byihuse birashobora gutera plaque, bisaba uburimbane.

Ibibi bya PCB Guteka nibintu byo gusuzuma
1. Guteka Bizihutisha okidation ya PCB hejuru yubuso bwa PCB, kandi hejuru yubushyuhe, igihe kirekire cyo guteka, niko abadakira cyane.

2. Ntabwo bisabwa guteka ibibaho byavuwe hejuru yubushyuhe bwinshi, kuko firime ya OSP izatesha agaciro cyangwa kunanirwa kubera ubushyuhe bwinshi. Niba ugomba guteka, birasabwa gukodesha ku bushyuhe bwa 105 ± 5 ° C, ntabwo bisabwa kubikoresha mumasaha 24 nyuma yo guteka.

3. Guteka bishobora kugira ingaruka ku ishyirwaho rya IMC, cyane cyane kuri Hasl (amabati), imp yinjira mu gisekuru cya PCB, ariko, izaba ikigo cy'imikino ngororamubiri.
