Chifukwa chiyani PCB (bolodi losindikizidwa) liyenera kupakidwa utoto ndi zida zokutira zofananira?Kodi molondola komanso mwamsanga kujambula bolodi dera?

PCB amatanthauza kusindikizidwa dera bolodi, amene ndi WOPEREKA magetsi kugwirizana zigawo zikuluzikulu pakompyuta.Ndizofala kwambiri pamakampani amagetsi, ndipo zokutira zofananira zimagwiritsidwanso ntchito kwambiri.Palibe zomatira PCB atatu proofing guluu (penti).M'malo mwake, ndikuyika nsanjika ya zokutira zofananira pa PCB.

Zida zokutira zofananira 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, utoto wotsimikizira katatu umagwiritsidwa ntchito kwambiri pama board ozungulira.

Zomwe zingayambitse PCB kuwonongeka:

Chinyezi ndiye chinthu chofala kwambiri komanso chowononga ku 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 zobiriwira zamkuwa, zomwe zimayambitsidwa ndi zomwe zimachitika mkuwa wachitsulo ndi nthunzi yamadzi ndi mpweya.

Mazana a zoipitsa zopezeka mwachisawawa pa matabwa ozungulira osindikizidwa ali ndi mphamvu yowononga yofanana.Zitha kubweretsa zotsatira zofanana ndi kukokoloka kwa chinyezi, monga kuwonongeka kwamagetsi, kuwonongeka kwa ma conductor komanso ngakhale kufupika.Zoipitsa zomwe nthawi zambiri zimapezeka mumagetsi amatha kukhala zinthu zomwe zimasiyidwa.Zowononga izi zimaphatikizapo flux, zosungunulira zosungunulira, tinthu tachitsulo ndi inki yolembera.

Palinso magulu akuluakulu owononga chilengedwe chifukwa cha manja a anthu, monga mafuta a anthu, 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 muyenera kugwiritsa ntchito guluu atatu proofing (penti)?

PCB yokutidwa ndi conformal ❖ kuyanika zipangizo sangakhale chinyezi-umboni, fumbi-umboni ndi madzi, komanso ndi katundu kuzizira ndi kutentha mantha kukana, kukana ukalamba, kukana radiation, kukana chifunga mchere, ozoni dzimbiri kukana, kugwedera kugwedezeka, kusinthasintha kwabwino komanso kumamatira mwamphamvu.Zikakhudzidwa ndi zovuta zomwe zimagwira ntchito, zimatha kuchepetsa kapena kuthetsa kuchepa kwa ntchito zamagetsi.

Chifukwa cha malo osiyanasiyana ogwiritsira ntchito zinthu zosiyanasiyana zomaliza, zofunikira zogwirira ntchito za zomatira zotsimikizira zitatu zidzatsindikiridwa.Zida zapakhomo monga mafiriji, makina ochapira ndi zotenthetsera madzi zimakhala ndi zofunika kwambiri pakukana chinyezi, pomwe mafani akunja ndi nyali zamsewu zimafunikira magwiridwe antchito abwino kwambiri oletsa chifunga.

Momwe mungagwiritsire ntchito mwachangu komanso moyenerazokutira conformalku PCB?

M'makampani opanga ma PCB, pali zida zodziwikiratu zodzitchinjiriza zodzitchinjiriza zodzitchinjiriza za matabwa ozungulira - makina opaka utoto, omwe amadziwikanso kuti makina opaka utoto otsimikizira atatu, makina opopera opaka utoto atatu, makina atatu opaka utoto otsimikizira, kupopera utoto katatu kotsimikizira utoto. makina, etc., amene anadzipereka kulamulira madzimadzi ndi kuphimba wosanjikiza atatu umboni utoto pamwamba PCB, monga kuphimba wosanjikiza photoresist padziko PCB ndi impregnation, kupopera mbewu mankhwalawa kapena sapota ❖ kuyanika.

Makina opaka conformal amagwiritsidwa ntchito makamaka kupopera mbewu mankhwalawa molondola, kupaka ndi kudontha zomatira, utoto ndi zakumwa zina popanga zinthuzo mpaka pamalo enieni a chinthu chilichonse.Itha kugwiritsidwa ntchito kujambula mizere, mabwalo kapena ma arcs.

Makina okutikira okhazikika ndi zida zopopera mankhwala zopangidwira mwapadera kupopera utoto wotsimikizira katatu.Chifukwa cha zinthu zosiyanasiyana zomwe zimayenera kupopera ndi madzi opopera mankhwala, kusankha kwa chigawo cha makina opangira makina opangira zida ndi zosiyana.Makina atatu opangira utoto amatengera pulogalamu yaposachedwa yowongolera makompyuta, yomwe imatha kuzindikira kulumikizana kwa ma axis atatu.Panthawi imodzimodziyo, imakhala ndi makina owonetsera makamera ndi kufufuza, zomwe zingathe kulamulira molondola malo opoperapo mankhwala.
