PCB amatanthauza kusindikizidwa dera bolodi (Kusindikizidwa dera bolodi), amene ndi WOPEREKA kugwirizana magetsi zigawo zikuluzikulu zamagetsi.Ndizofala kwambiri m'makampani opanga zamagetsi, ndipo atatu odana ndi zomatira (penti) amagwiritsidwa ntchito kwambiri mmenemo, ndipo palibe zomatira ngati PCB zomatira katatu (penti).M'malo mwake, zomatira zotsimikizira katatu (penti) zimakutidwa pa PCB.utoto).
Kugwiritsa ntchito ma anti-penti atatu ndikuletsa PCB kuti isawonongeke ndi zinthu zakunja ndikuwongolera moyo wautumiki wa PCB.Monga zida zapamwamba zamagetsi zimakhala ndi zofunikira zapamwamba komanso zapamwamba zamtundu wa PCB, zokutira zofananira zimagwiritsidwa ntchito kwambiri pama board ozungulira.
Zomwe zimayambitsa kuwonongeka kwa PCB:
Chinyezi ndiye chinthu chofala kwambiri komanso chowononga kwambiri ma PCB.Chinyezi chambiri chidzachepetsa kwambiri kukana kwa insulation pakati pa ma conductor, kufulumizitsa kuwonongeka, kuchepetsa mtengo wa Q, ndikuwononga ma conductor.Nthawi zambiri zimachitika kuti mbali yachitsulo ya PCB imakhala ndi patina, yomwe imayamba chifukwa cha mankhwala a mkuwa wachitsulo ndi nthunzi yamadzi ndi mpweya.
Monga momwe zimawonongera mazana a zonyansa zomwe mungapeze mwachisawawa pa bolodi losindikizidwa, ndipo zingayambitse zotsatira zofanana ndi kuwononga chinyezi, monga kulephera kwamagetsi, kuwonongeka kwa ma kondakitala, ngakhale maulendo afupiafupi.Zoipitsa zomwe zimapezeka nthawi zambiri m'makina amagetsi zimatha kukhala zinthu zomwe zimasiyidwa popanga.Zowononga izi zimaphatikizapo zotuluka, zosungunulira, tinthu tachitsulo, ndi inki zolembera.
Palinso magulu akuluakulu oipitsidwa ndi manja a anthu, monga mafuta a thupi, zizindikiro za zala, zodzoladzola ndi zotsalira za zakudya.Palinso zowononga zambiri m'malo ogwirira ntchito, monga kutsitsi mchere, mchenga, mafuta, asidi, nthunzi zina zowononga ndi nkhungu.
N'chifukwa chiyani odana ndi zomatira (penti) atatu?
PCB wokutidwa ndi atatu odana zomatira (penti) osati chinyezi-umboni, fumbi-umboni, ndi madzi, komanso kukana kuzizira ndi kutentha mantha, kukalamba kukana, kukana radiation, kutsitsi kutsitsi mchere, ozoni dzimbiri kukana, kugwedera. kukana, kusinthasintha kwabwino komanso kumamatira mwamphamvu.Zikakhudzidwa ndi zovuta zomwe zimagwira ntchito, zimatha kuchepetsa kapena kuthetsa kuwonongeka kwa magwiridwe antchito amagetsi.
Chifukwa cha madera osiyanasiyana ogwiritsira ntchito zinthu zosiyanasiyana zomaliza, zofunikira pakugwira ntchito kwa zomatira zofananira zidzatsindikiridwa.Zida zapakhomo monga mafiriji, makina ochapira, ndi zotenthetsera madzi zimakhala ndi zofunika kwambiri pakukana chinyezi, pomwe mafani akunja ndi nyali zamumsewu zimafunikira zinthu zothana ndi chifunga.
Momwe mungagwiritsire ntchito zomatira (penti) mwachangu komanso moyenera ku PCB?
M'makampani opanga ma PCB, pali zida zodziwikiratu zopaka utoto wodzitchinjiriza pama board ozungulira - makina atatu opaka utoto, omwe amadziwikanso kuti makina atatu oletsa utoto, makina atatu opopera utoto, atatu opopera mafuta oletsa utoto. , atatu odana utoto utoto kupopera utoto makina, etc., lakonzedwa kulamulira madzimadzi, ndi kuphimba wosanjikiza utoto conformal pamwamba pa PCB, monga kuphimba wosanjikiza photoresist pamwamba pa PCB ndi kuviika, kupopera mbewu mankhwalawa. kapena spin coating.
Makina atatu oletsa utoto amagwiritsidwa ntchito makamaka kupopera mbewu mankhwalawa molondola, kuphimba ndi kudontha zomatira, utoto ndi zakumwa zina zomwe zimagwiritsidwa ntchito popanga zinthuzo mpaka pamalo enieni a chinthu chilichonse, ndipo zitha kugwiritsidwa ntchito kukwaniritsa zojambula za mzere, bwalo kapena arc.
Makina atatu okutira oletsa utoto ndi zida zopopera mankhwala zopangidwira mwapadera kupopera mafuta atatu oletsa utoto.Popeza zida zopopera ndi kupopera madzi kuti zigwiritsidwe ndizosiyana, magawo osankhidwa a makina opaka potengera kapangidwe ka zida ndizosiyana.Makina atatu oletsa utoto amatengera pulogalamu yaposachedwa yoyang'anira makompyuta, yomwe imatha kuzindikira kulumikizana kwa ma axis atatu, ndipo imakhala ndi The camera positioning tracking system imatha kuwongolera molondola malo opoperapo mankhwala.
