PCBA conformal barbotage ho fafatsa tshebetso tshebetso phallo
Ho latela bareki ba hloka, Cirket e boetse e na le ts'ebeletso ea ho roala ka mokhoa o ts'oanang.PCBA conformal coating e na le insulation e ntle haholo, e thibelang mongobo, e thibela ho lutla, ho ts'oha, ho thibela lerōle, ho thibela kutu, ho thibela botsofali, ho thibela hlobo, ho thibela karolo. ho lokoloha le ho kenya thepa ea ho hanyetsa corona, e ka eketsang nako ea polokelo ea PCBA. Cirket e lula e sebelisa Spraying eo hape e leng mokhoa o sebelisoang haholo indastering.
Cirket PCBA conformal barbotage ho fafatsa tshebetso ho phalla
1. Lisebelisoa tse hlokahalang
Pente e tlokomang e hlophisitsoeng, lebokose la pente, liatlana tsa rabara, maske kapa mask a khase, borashe, teipi e khomarelang, li-tweezers, lisebelisoa tsa moea, rack le onto.
2. Mehato ea ho fafatsa
Ho penta lehlakore A → ho omisa holim'a metsi → ho penta lehlakore la B → ho phekola tlas'a mocheso oa kamore
3. Litlhoko tsa ho roala
(1) Hloekisa le ho omisa boto ho tlosa mongobo le metsi a PCBA. Lerōle, mongobo le oli holim'a PCBA e lokelang ho roaloa e tlameha ho tlosoa pele e le hore ho roala ho ka hlahisa phello ea eona ea tšireletso ka botlalo. Ho hloekisa ka ho feletseng ho ka etsa bonnete ba hore masala a senyang a tlosoa ka ho feletseng 'me seaparo sa conformal se khomarela hantle holim'a boto ea potoloho. Maemo a ho baka: 60 ° C, metsotso e 10-20. Phello e ntle ka ho fetisisa ea ho roala ke ho fafatsa ha boto e chesa ka mor'a hore e ntšoe ka ontong.
(2) Ha u hlatsoa seaparo sa conformal, sebaka sa ho roala se lokela ho ba seholo ho feta sebaka se sebelisoang ke likarolo ho etsa bonnete ba hore likarolo tsohle le liphahlo li koahetsoe.
(3) Ha u hlatsoa seaparo sa conformal, boto ea potoloho e lokela ho behoa e bataletse ka hohle kamoo ho ka khonehang. Ha hoa lokela ho ba le marotholi ka mor'a ho hlatsoa. Ho roala ho lokela ho ba boreleli 'me ha hoa lokela ho ba le likarolo tse pepenene. Botenya bo lokela ho ba pakeng tsa 0.1-0.3mm.
(4) Pele o hlatsoa kapa o fafatsa litlolo tse lumellanang, basebetsi ba Cirket ba etsa bonnete ba hore seaparo se hlapolotsoeng se tsitsitse ka botlalo 'me se siuoa lihora tse 2 pele se hlatsoa kapa se fafatsa. Sebelisa borashe ba faeba ea boleng bo holimo ho borashe le ho inela mochesong oa kamore. Haeba u sebelisa mochine , viscosity ea ho roala e lokela ho lekanyetsoa (ho sebelisa tester ea viscosity kapa senoelo sa phallo) le viscosity e ka fetoloa ka diluent.
• Likarolo tsa boto ea potoloho li lokela ho qoelisoa ka mokhoa o otlolohileng ka har'a tanka ea ho roala bonyane motsotso ho fihlela li-bubble li nyamela ebe li tlosoa butle. Ka kopo hlokomela hore likhokahano ha lia lokela ho qoelisoa ntle le haeba li koahetsoe ka hloko. Filimi e ts'oanang e tla theha holim'a boto ea potoloho. Boholo ba masala a pente a lokela ho phalla morao ho tloha boto ea potoloho ho ea mochine oa ho qoela. TFCF e na le litlhoko tse fapaneng tsa ho roala. Lebelo la ho qoelisa boto ea potoloho kapa likarolo ha lia lokela ho potlaka haholo ho qoba li-bubble tse feteletseng.
(6) Haeba ho na le lekhapetla holim'a metsi ha le sebelisoa hape ka mor'a ho qoelisoa, tlosa letlalo 'me u tsoele pele ho le sebelisa.
(7) Ka mor'a ho hlatsoa, beha boto ea potoloho e bataletseng holim'a bracket 'me u lokisetse ho phekola. Hoa hlokahala ho futhumatsa ho potlakisa phekolo ea ho roala. Haeba sebaka sa ho roala se sa lekane kapa se na le li-bubble, se lokela ho behoa tlas'a mocheso oa kamore nako e telele pele se phekola ka sebōping sa mocheso o phahameng ho lumella solvent hore e khanye.
Mehato ya tlhokomelo
1. Nakong ea ts'ebetso ea ho fafatsa, likarolo tse ling li ke ke tsa fafatsoa, tse kang: matla a phahameng a ho senya mocheso kapa lisebelisoa tsa mocheso oa mocheso, lisebelisoa tsa matla, li-diode tsa matla, li-resistors tsa samente, li-switches tsa dip, li-resistors tse fetolehang, li-buzzers, li-betri, li-fuse holders ( li-tubes), li-IC, li-switches, joalo-joalo.
2. Ho thibetsoe ho tšela pente e setseng e nang le bopaki bo tharo hape ka har'a setsi sa pele sa polokelo. E tlameha ho bolokoa ka thoko le ho koaloa.
3. Haeba kamore ea ho sebeletsa kapa ea polokelo e koetsoe nako e telele (ho feta lihora tse 12), e ntše moea ka metsotso e 15 pele u kena.
4. Haeba ka phoso e phatloha ka har'a likhalase, ka kopo bula mahlo a ka holimo le a tlaase hang-hang 'me u hlatsoe ka metsi a phallang kapa saline, ebe u batla phekolo ea bongaka.
