1. Chifukwa chiyani BGA ili mu dzenje la solder mask?Kodi muyezo wolandirira alendo ndi wotani?
Re: Choyamba, solder chigoba pulagi dzenje ndi kuteteza moyo utumiki wa kudzera, chifukwa dzenje chofunika BGA udindo zambiri ang'onoang'ono, pakati pa 0,2 ndi 0.35mm.Madzi ena si ophweka kuumitsa kapena kuwumitsa nthunzi, ndipo n'kosavuta kusiya zotsalira.Ngati chigoba cha solder sichimangirira dzenje kapena pulagi sinadzaze, padzakhala zotsalira zakunja kapena mikanda ya malata pakukonza kotsatira monga kupopera tini ndi golide womiza.Wogula akamawotcha chigawocho panthawi yotentha kwambiri, zinthu zakunja kapena mikanda ya malata mu dzenje idzatuluka ndikumamatira ku chigawocho, zomwe zimapangitsa kuti pakhale zolakwika pamagulu, monga maulendo otseguka ndi afupi.BGA ili mu dzenje la solder A, liyenera kukhala lodzaza B, palibe kufiira kapena kuwonetsa mkuwa wabodza kumaloledwa, C, osadzaza kwambiri, ndipo mawonekedwe ake ndi apamwamba kuposa pad kuti agulitsidwe pafupi ndi izo (zomwe zingakhudze chigawo mounting Effect). 
2. Kodi pali kusiyana kotani pakati pa galasi pamwamba pa tebulo la makina owonetsera ndi galasi wamba?Nchifukwa chiyani chiwonetsero cha nyali yoyaka sichikufanana? Re: Galasi la tebulo la makina owonetsera silidzatulutsa kuwala pamene kuwala kumadutsamo.Ngati chonyezimira cha nyali yowonekera chimakhala chathyathyathya komanso chosalala, ndiye kuti kuwala kukuwalira, molingana ndi mfundo ya kuwala, kumapanga kuwala konyezimira kowala pa bolodi kuti kuwululidwe.Ngati dzenje liri lowoneka bwino komanso losagwirizana molingana ndi kuwala Mfundo yake ndi yakuti kuwala kowala pamphepete ndi kuwala kowala pazitsulo kudzapanga kuwala kosawerengeka komwe kumabalalika, kupanga kuwala kosasinthasintha koma kofanana pa bolodi kuti iwonetsedwe, kuwongolera kuwala. zotsatira za kuwonekera. 
3. Kodi mbali chitukuko ndi chiyani?Zotsatira zabwino zomwe zimachitika chifukwa chakukula kwa mbali ndi ziti? Re: Dera la m'lifupi pansi pa gawo lomwe mafuta obiriwira kumbali imodzi ya zenera la solder mask apangidwa amatchedwa chitukuko cha mbali.Pamene chitukuko cham'mbali chimakhala chachikulu kwambiri, zikutanthauza kuti malo obiriwira obiriwira a gawo lomwe limapangidwira komanso lomwe limagwirizana ndi gawo lapansi kapena khungu lamkuwa ndilokulirapo, ndipo mlingo wa dangling wopangidwa ndi izo ndi waukulu.Kukonzekera kotsatira monga kupopera tini, kumiza kwa malata, Kumizidwa kwa golidi ndi mbali zina zomwe zikukula zimakhudzidwa ndi kutentha kwakukulu, kupanikizika ndi zina zomwe zimakhala zovuta kwambiri ku mafuta obiriwira.Mafuta adzagwa.Ngati pali mlatho wobiriwira wamafuta pa malo a IC, izi zimachitika pamene kasitomala ayika zida zowotcherera.Zidzachititsa kuti mlatho ukhale wozungulira.
4. Kodi kuwonekera kwa chigoba cha solder ndi chiyani?Zidzabweretsa zotsatira zabwino zotani? Re: Pambuyo pokonzedwa ndi ndondomeko ya solder mask, imawululidwa ku mapepala a zigawozo kapena malo omwe amayenera kugulitsidwa pambuyo pake.Pa solder chigoba mayikidwe / kukhudzana ndondomeko, izo amayamba ndi kuwala chotchinga kapena kukhudzana mphamvu ndi mavuto ntchito.Kunja kapena mafuta onse obiriwira omwe amaphimbidwa ndi gawoli amawonekera pakuwala kuti apangitse kulumikizana.Pachitukuko, mafuta obiriwira mu gawo ili sangasungunuke ndi yankho, ndipo kunja kapena zonse za pad kuti zigulitsidwe sizingawonekere.Izi zimatchedwa soldering.Kuwonetsedwa koyipa.Kuwonetsedwa koyipa kumabweretsa kulephera kuyika zigawo muzotsatira, kusasunthika kosasunthika, ndipo, muzovuta kwambiri, kuzungulira kotseguka. 5. N'chifukwa chiyani tiyenera kukonza mbale mphero kwa mawiring ndi solder chigoba? Re: 1. Dongosolo la bolodi la dera limaphatikizapo chigawo chopangidwa ndi zojambulazo ndi gawo lapansi ndi mkuwa wopangidwa kale pambuyo pa dzenje metallization.Pofuna kuonetsetsa kumatira kolimba pakati pa filimu yowuma ndi gawo lapansi la gawo lapansi, gawo lapansili liyenera kukhala lopanda zigawo za oxide, madontho amafuta, zisindikizo za zala ndi zinyalala zina, osabowola burrs, komanso plating yovuta.Pofuna kuonjezera malo okhudzana ndi filimu yowuma ndi pamwamba pa gawo lapansi, gawo lapansili likufunikanso kuti likhale ndi malo ochepa kwambiri.Pofuna kukwaniritsa zofunikira ziwirizi, gawo lapansi liyenera kukonzedwa mosamala musanajambule.Njira zochiritsira zitha kufotokozedwa mwachidule ngati kuyeretsa kwamakina ndi kuyeretsa mankhwala.
2. Mfundo yomweyi ndi yowona pa chigoba cha solder chomwecho.Kupera bolodi musanayambe kugulitsa chigoba ndikuchotsa zigawo zina za okusayidi, madontho amafuta, zala zala ndi dothi lina pamwamba pa bolodi, kuti muwonjezere malo olumikizana pakati pa inki ya solder ndi bolodi ndikupangitsa kuti ikhale yolimba.Pamwamba pa bolodi pamafunikanso kuti pakhale malo ocheperako (monga tayala lokonzekera galimoto, tayala liyenera kugwedezeka pamtunda kuti ligwirizane bwino ndi guluu).Ngati mulibe ntchito akupera pamaso dera kapena solder chigoba, pamwamba pa bolodi kuti pasted kapena kusindikizidwa ali ena okusayidi zigawo, madontho mafuta, etc., izo mwachindunji kulekanitsa solder chigoba ndi dera filimu ku bolodi padziko Fomu. kudzipatula, ndipo filimuyi pamalo ano idzagwa ndikusenda pakapita nthawi. 6. Kodi mamasukidwe akayendedwe ndi chiyani?Kodi kukhuthala kwa inki ya solder kumakhudza bwanji kupanga PCB? Re: Viscosity ndi njira yopewera kapena kukana kuyenda.The mamasukidwe akayendedwe a solder chigoba inki ali ndi chikoka pa kupanga PCB .Pamene mamasukidwe akayendedwe kwambiri, n'zosavuta chifukwa palibe mafuta kapena kukakamira ukonde.Pamene mamasukidwe akayendedwe otsika kwambiri, fluidity inki pa bolodi adzawonjezeka, ndipo n'zosavuta chifukwa mafuta kulowa dzenje.Ndipo buku laling'ono lamafuta.Kunena zoona, mkuwa wakunja ukakhala wandiweyani (≥1.5Z0), kukhuthala kwa inki kuyenera kuyendetsedwa kuti kukhale kutsika.Ngati mamasukidwe akayendedwe ndi okwera kwambiri, fluidity wa inki adzachepa.Panthawiyi, pansi ndi ngodya za dera sizidzakhala mafuta kapena zowonekera. 7. Kodi pali kufanana ndi kusiyana kotani pakati pa kusakula bwino ndi kusawonekera bwino? Re: Mfundo zomwezi: a.Pali mafuta a chigoba cha solder pamwamba pomwe mkuwa / golide amafunika kugulitsidwa pambuyo pa chigoba cha solder.Chifukwa cha b ndi chimodzimodzi.Nthawi, kutentha, nthawi yowonekera ndi mphamvu za pepala lophika ndizofanana. Kusiyanasiyana: Dera lomwe limapangidwa chifukwa chosawoneka bwino ndilokulirapo, ndipo chigoba chotsalira cha solder chimachokera kunja kupita mkati, ndipo m'lifupi ndi Baidu ndizofanana.Ambiri aiwo amawonekera pamapazi opanda porous.Chifukwa chachikulu ndi chakuti inki yomwe ili m'gawoli imawonekera ku kuwala kwa ultraviolet.Kuwala kumawala.Mafuta otsalira a solder mask kuchokera ku chitukuko chosauka amangokhala ochepa kwambiri pansi pa wosanjikiza.Dera lake si lalikulu, koma limapanga dziko lochepa la filimu.Mbali iyi ya inki makamaka chifukwa cha zinthu zosiyanasiyana machiritso ndipo apangidwa kuchokera pamwamba wosanjikiza inki.Mawonekedwe a hierarchical, omwe nthawi zambiri amawonekera pamabowo.
8. Chifukwa chiyani chigoba cha solder chimatulutsa thovu?Kodi kupewa izo? Re: (1) Mafuta a chigoba cha solder nthawi zambiri amasakanizidwa ndikupangidwa ndi wothandizila wamkulu wa inki + wochiritsa + diluent.Pakusakaniza ndi kugwedeza kwa inki, mpweya wina umakhalabe mumadzimadzi.Inki ikadutsa pa chopukutira, waya Pambuyo pofinyidwa maukonde wina ndi mzake ndikuyenderera pa bolodi, akakumana ndi kuwala kwamphamvu kapena kutentha kofanana mu nthawi yochepa, mpweya wa inki udzayenda mofulumira ndi kuthamanga kwapakati. inkiyo, ndipo idzaphulika kwambiri.
(2), mizere yotalikirana ndi yopapatiza kwambiri, mizereyo ndi yokwera kwambiri, inki ya solder sikhoza kusindikizidwa pa gawo lapansi panthawi yosindikiza, zomwe zimapangitsa kukhalapo kwa mpweya kapena chinyezi pakati pa inki ya solder ndi gawo lapansi, ndi mpweya umatenthedwa kuti uwonjezeke ndikupangitsa thovu pakuchiritsa ndi kuwonekera.
(3) Mzere umodzi umayambitsidwa makamaka ndi mzere wapamwamba.Pamene squeegee ikukhudzana ndi mzere, mbali ya squeegee ndi mzerewu ukuwonjezeka, kotero kuti inki ya mask ya solder sichikhoza kusindikizidwa pansi pa mzere, ndipo pali mpweya pakati pa mbali ya mzere ndi mask solder. inki , Mtundu wa thovu laling'ono lidzapangidwa likatenthedwa.
Kupewa:
a.Inki yopangidwa imakhala yokhazikika kwa nthawi inayake isanasindikizidwe,
b.The kusindikizidwa bolodi amakhalanso static kwa nthawi inayake kuti mpweya inki pamwamba pa bolodi pang'onopang'ono volatilize ndi otaya inki, ndiyeno kuchotsa izo kwa nthawi yochuluka.Kuphika pa kutentha.
