1. Nei BGA iri mune solder mask gomba?Chii chinonzi reception standard?
Re: Chekutanga, iyo solder mask plug gole ndeyekudzivirira hupenyu hwesevhisi yeVia, nekuti gomba rinodiwa panzvimbo yeBGA kazhinji idiki, pakati pe0.2 ne0.35mm.Imwe sirapu haisi nyore kuomeswa kana kuputika, uye zviri nyore kusiya zvisaririra.Kana iyo solder mask ikasavhara gomba kana plug isina kuzara, pachasara zvinhu zvekune dzimwe nyika kana marani mabhedhi mukugadzirisa kunotevera sekupfapfaidza tin uye kunyudza goridhe.Kana mutengi achinge apisa chikamu panguva yekupisa-kupisa kwekushisa, nyaya yekunze kana tin beads mugomba ichayerera kunze uye inonamatira kune chikamu, zvichikonzera kukanganisa mukuita kwechikamu, senge yakavhurika uye mapfupi maseketi.Iyo BGA iri mune solder mask gomba A, inofanira kunge izere B, hapana kutsvuka kana nhema kuratidzwa kwemhangura kunobvumidzwa, C, isina kuzara, uye iyo protrusion yakakwira kupfuura padhi inotengeswa padivi payo (izvo zvinokanganisa component mounting Effect). 
2. Ndeupi musiyano uripo pakati pegirazi repamusoro petafura yemuchina wekufumura uye girazi rakajairwa?Nei chiratidziro chemwenje wekuvhenekera chisina kuenzana? Re: Girazi retafura yemuchina wekuvhenekesa hauburitse mwenje wekuratidzira kana mwenje uchipfuura nemo.Kana mucherechedzo wemwenje wekuvhenekera wakapfava uye wakapfava, ipapo kana mwenje uchivhenekera pairi, maererano nemusimboti wechiedza, unoumba chiedza chimwe chete chinoratidzwa chinopenya pabhodhi kuti chionekwe.Kana gomba riri convex uye risina kuenzana maererano nechiedza Nheyo yacho ndeyokuti chiedza chinovhenekera pamashure uye chiedza chinopenya pamaprotrusions chichaumba zvisingaverengeki zvakapararira zviedza zvechiedza, zvichiita chiedza chisina kujairika asi chakafanana pabhodhi kuti chionekwe, kuvandudza mhedzisiro yekufumurwa. 
3. Chii chinonzi side development?Ndeapi mhedzisiro yemhando inokonzerwa nekusimudzira kwedivi? Re: Nzvimbo yehupamhi pazasi pechikamu icho mafuta egirini kune rimwe divi re solder mask hwindo rakagadzirwa rinonzi side development.Kana rutivi rwekusimudzirwa rwakanyanya, zvinoreva kuti nzvimbo yemafuta yakasvibirira yechikamu chinogadzirwa uye iyo inosangana ne substrate kana ganda remhangura yakakura, uye dhigirii yekurembera yakaumbwa nayo yakakura.Iko kunotevera kugadzirisa senge kupfapfaidza tin, kunyura kwerata, Kunyudza goridhe uye mamwe mativi ari kusimukira zvikamu zvinorwiswa nekupisa kwakanyanya, kudzvanywa uye mamwe mapotions anowedzera hutsinye kumafuta egirinhi.Mafuta achadonha.Kana paine bhiriji remafuta egirinhi pane iyo IC chinzvimbo, zvinokonzeresa kana mutengi achiisa zvinhu zvewelding.Ichaita kuti bhiriji ripfupike.
4. Chii chinonzi murombo solder mask exposure?Zvichakonzera hunhu hwei? Re: Mushure mekugadziriswa neiyo solder mask process, inoratidzwa kune mapedhi ezvikamu kana nzvimbo dzinoda kutengeswa mune inotevera maitiro.Munguva ye solder mask alignment / exposure process, inokonzerwa nemwenje chipingamupinyi kana kuratidzwa kwesimba uye matambudziko ekushanda.Kunze kana ese egirinhi mafuta akafukidzwa nechikamu ichi anovhenekerwa nechiedza kuti akonzerese kupindirana.Munguva yekuvandudza, mafuta egirini ari muchikamu ichi haaparadzwe nemhinduro, uye kunze kana yese yepadhi inotengeswa haigone kuburitswa.Izvi zvinonzi soldering.Kusaonekwa zvakanaka.Kusaratidzwa kwakashata kunozokonzera kutadza kukwidza zvikamu mune inotevera maitiro, kushata soldering, uye, mune zvakakomba, dunhu rakavhurika. 5. Nei tichida kufanogadzirisa ndiro yekukuya ye wiring uye solder mask? Re: 1. Musoro webhodhi wepamusoro unosanganisira foil-clad board substrate uye substrate ine pre-plated mhangura mushure megomba metallization.Kuti uve nechokwadi chekunamatira kwakasimba pakati pefirimu yakaoma uye substrate pamusoro, iyo substrate yepamusoro inodiwa kuti ive isina oxide layer, mafuta mavara, zvigunwe zvemunwe uye imwe tsvina, pasina kudhirowa burrs, uye isina rough plating.Kuti uwedzere nzvimbo yekubatana pakati pefirimu yakaoma uye pamusoro pe substrate, iyo substrate inofanirwawo kuva ne-micro-rough surface.Kuti zvizadzise zvinodiwa zviviri zviri pamusoro, iyo substrate inofanira kunyatsogadziriswa isati yatorwa.Nzira dzekurapa dzinogona kupfupikiswa sekuchenesa kwemakanika uye kuchenesa makemikari.
2. Nheyo imwechete ndeyechokwadi kune imwechete solder mask.Kukuya bhodhi pamberi pe solder mask ndiko kubvisa mamwe oxide layer, mafuta mavara, zvigunwe uye imwe tsvina pabhodhi repamusoro, kuitira kuti uwedzere nzvimbo yekubatanidza pakati peinotengeswa mask inki uye bhodhi pamusoro uye kuita kuti ive yakasimba.Bhodhi repamusoro rinodiwawo kuti rive ne-micro-rough surface (sezvinongoita vhiri rekugadzirisa motokari, vhiri rinofanira kunge rakavhuniwa kusvika panzvimbo yakaoma kuitira kuti zvibatane zviri nani neglue).Kana iwe usingashandisi kukuya pamberi pedunhu kana solder mask, iyo pamusoro pebhodhi ichanamatidzwa kana kudhindwa ine mamwe oxide layer, mafuta mavara, nezvimwewo, ichaparadzanisa zvakananga solder mask uye firimu redunhu kubva pabhodhi pamusoro Fomu. Kuzviparadzanisa nevamwe, uye firimu iri panzvimbo ino rinodonha uye rinoputika mune inotevera maitiro. 6. Chii chinonzi viscosity?Chii chinoita kuti viscosity ye solder mask inki ine paPCB kugadzirwa? Re: Viscosity chiyero chekudzivirira kana kuramba kuyerera.Iyo viscosity yeiyo solder mask inki ine simba rakakura pakugadzirwa kwe PCB .Kana iyo viscosity yakanyanya kukwirira, zviri nyore kusakonzera mafuta kana kunamatira kune mambure.Kana iyo viscosity yakanyanya kuderera, iyo fluidity yeinki pabhodhi ichawedzera, uye zviri nyore kuita kuti mafuta apinde mugomba.Uye yemuno sub-oiri bhuku.Zvichienderana, kana iyo yekunze yemhangura yakakora (≥1.5Z0), viscosity yeinki inofanira kudzorwa kuti iderere.Kana iyo viscosity yakanyanya kukwirira, iyo fluidity yeinki inoderera.Panguva ino, pasi uye makona edunhu iri Hazvizove nemafuta kana kuratidzwa. 7. Ndezvipi zvakafanana uye kusiyana pakati pekukura kusina kunaka uye kuratidzwa kusina kunaka? Re: Mapoinzi mamwe chete: a.Kune solder mask mafuta pamusoro peiyo mhangura / goridhe inoda kutengeswa mushure meiyo solder mask.Chikonzero che b chakafanana.Iyo nguva, tembiricha, nguva yekuratidzwa uye simba rebiki pepa zvakangofanana. Misiyano: Iyo nzvimbo inoumbwa nekusachena kuratidzwa yakakura, uye yakasara solder mask iri kubva kunze kuenda mukati, uye hupamhi neBaidu zvakaringana.Vazhinji vavo vanoonekwa pane asiri-porous pads.Chikonzero chikuru ndechekuti inki iri muchikamu ichi inoratidzwa kune ultraviolet chiedza.Chiedza chinopenya.Iyo yakasara solder mask mafuta kubva mukukura kwakashata inongova yakaonda pazasi pedhiri.Nzvimbo yaro haisi hombe, asi inoumba yakaonda firimu mamiriro.Ichi chikamu cheingi chinonyanya kukonzerwa nezvikonzero zvakasiyana-siyana zvekuporesa uye inoumbwa kubva pamucheka wepamusoro.Chimiro che hierarchical, icho chinowanzo onekwa pane buri pedhi.
8. Sei solder mask ichibudisa mabubbles?Nzira yekudzivirira sei? Re: (1) Solder mask mafuta anowanzo kusanganiswa uye anogadzirwa nemumiririri mukuru weinki + kurapa mumiririri + diluent.Munguva yekusanganiswa uye kubvongodza inki, imwe mhepo icharamba iri mumvura.Kana iyo ingi ichipfuura nepakati, waya Mushure mekunge mambure adzvanywa mukati memumwe nemumwe uye achiyerera achipinda pabhodhi, kana asangana nechiedza chakasimba kana tembiricha yakaenzana munguva pfupi, gasi iri muinki richayerera nekukurumidza pamwe nekuwedzera kukurumidza kwe. iyo ingi, uye ichaputika zvakanyanya.
(2), mutsara wemutsara wakanyanya kutetepa, mitsetse yakawandisa, iyo solder mask inki haigone kudhindwa pane substrate panguva yekudhinda skrini, zvichikonzera kuvepo kwemhepo kana hunyoro pakati peiyo solder mask inki uye substrate, uye gasi rinopisa kuti riwedzere uye rikonzere mabhuru panguva yekurapa uye kuratidzwa.
(3) Mutsara mumwe chete unonyanya kukonzerwa nemutsara wepamusoro.Kana iyo squeegee inosangana nemutsara, kona ye squeegee uye mutsara unowedzera, kuitira kuti solder mask inki haigoni kudhindwa kusvika pasi pemutsara, uye kune gasi pakati perutivi rwemutsara uye solder mask. inki , Rudzi rwematuru madiki achaumbwa kana apiswa.
Kudzivirira:
a.Iyo inki yakagadzirwa inomira kweimwe nguva yenguva isati yadhindwa,
b.Iyo yakadhindwa bhodhi zvakare static kune imwe nguva yenguva kuitira kuti gasi muinki iri pamusoro pebhodhi zvishoma nezvishoma riite volatilize nekuyerera kweinki, uye wozoitora kure kune imwe nguva.Bika pakupisa.
