Mumakore achangopfuura, kushandiswa kweinkjet kudhinda tekinoroji kudhinda kwemavara uye logos paPCB mabhodhi kwakaramba kuchiwedzera, uye panguva imwechete yakasimudza matambudziko akakwira kusvika pakupedzwa uye kusimba kwekudhinda inkjet. Nekuda kweiyo yakanyanya-yakaderera viscosity, iyo inkjet inodhinda inki kazhinji ine gumi nemaviri centipoises. Kuenzaniswa nemakumi ezviuru zvemacentipoise echinyakare skrini yekudhinda ingi, inkjet inodhinda inki inotarisisa kumamiriro epasi peiyo substrate. Kana iyo nzira ichidzorwa Kwete yakanaka, inowanzoitika kune matambudziko akadai seinki shrinkage uye hunhu hunodonha.
Kubatanidza kuunganidzwa kwehunyanzvi muhunyanzvi hwekutsikisa inkjet, Hanyin yanga ichibatirana nevatengi pakugadzirisa uye kugadzirisa nevagadziri veinki kwenguva yakareba panzvimbo yevatengi, uye yakaunganidza ruzivo runoshanda mukugadzirisa dambudziko rekunyora inkjet mavara.

Mhedzisiro yekushushikana kwepamusoro kweiyo solder mask
Kudzvinyirirwa kwepamusoro kwe solder mask kunobata zvakananga kunamatira kwemavara akadhindwa. Iwe unogona kutarisa uye kusimbisa kana hunhu hunodonha hune hukama nekukakavadzana kwepamusoro kuburikidza neiyo inotevera tafura yekuenzanisa.
Iwe unogona kazhinji kushandisa dyne peni kuti utarise tension yepasi ye solder mask usati wadhinda hunhu. Kazhinji kutaura, kana iyo tension yepasi inosvika 36dyn/cm kana kupfuura. Zvinoreva kuti iyo pre-yakabikwa solder mask inonyanya kukodzera kune maitiro ekudhinda maitiro.
Kana bvunzo ikaona kuti tension yepasi ye solder mask yakadzikira, ndiyo nzira yakanakisa yekuzivisa mugadziri wemasiki kuti abatsire mukugadzirisa.

Kufurira kwe solder mask film inodzivirira firimu
Mune solder mask exposure stage, kana firimu rinodzivirira firimu rinoshandiswa rine silicone oiri zvikamu, inozoendeswa kune solder mask pamusoro panguva yekuratidzwa. Panguva ino, zvinokanganisa maitiro pakati peink inki uye solder mask uye inokanganisa simba rekubatanidza, kunyanya Nzvimbo iyo pane zviratidzo zvemafirimu pabhodhi kazhinji ndiyo nzvimbo iyo mavara anonyanya kuwira. Muchiitiko ichi, zvinokurudzirwa kutsiva firimu rekudzivirira pasina mafuta e-silicone, kana kusashandisa firimu rekudzivirira firimu rekuenzanisa kuedza. Kana iyo firimu inodzivirira firimu isingashandiswe, vamwe vatengi vanozoshandisa imwe yemvura inodzivirira kuisa kune iyo firimu kuchengetedza firimu, kuwedzera kugona kwekuburitsa, uye zvakare kukanganisa mamiriro echiso che solder mask.
Mukuwedzera, pesvedzero yefirimu inodzivirira firimu inogonawo kusiyana zvichienderana nehuwandu hwekurwisa-kunamatira kwefirimu. Iyo dyne peni inogona kusakwanisa kuiyera zvakarurama, asi inogona kuratidza inki shrinkage, zvichiita kuti kusaenzana kana zvinetso zvepinhole, izvo zvichakanganisa kunamatira. Ita zvinobatika.

Kufurira kwekugadzira defoamer
Sezvo zvakasara zveiyo defoamer inokura ichakanganisawo kunamatira kweiyo inki, zvinokurudzirwa kuti hapana defoamer inowedzerwa pakati pemugadziri wekuenzanisa bvunzo kana wawana chikonzero.

Kufurira kwe solder mask solvent residue
Kana iyo pre-bake tembiricha ye solder mask yakadzikira, zvimwe zvinonyungudutsa mune solder mask zvinokanganisa chisungo neingi yehunhu. Panguva ino, zvinokurudzirwa kuwedzera zvakakodzera tembiricha ye-pre-bake uye nguva ye solder mask yekuenzanisa bvunzo.

Zvinodiwa pakudhinda mavara ingi
Iwo mavara anofanirwa kudhindwa pane solder mask isina kubikwa pakupisa kwakanyanya:
Ziva kuti mavara anofanirwa kudhindwa pane solder mask yekugadzira bhodhi iyo isina kubikwa pakupisa kwakanyanya mushure mekuvandudzwa. Kana iwe ukadhinda mavara pane yekuchembera solder mask, haugone kuwana kunamatira kwakanaka. Ngwarira kune shanduko dzinodiwa mukuita kwekugadzira. Iwe unofanirwa kushandisa bhodhi rakagadziridzwa kudhinda mavara kutanga, uye ipapo solder mask uye mavara anobikwa pakupisa kwakanyanya.
Seta maparamita ekupisa kupisa nemazvo:
Jet printing character inki inki inorapa mbiri. Kurapa kwese kwakakamurwa kuita matanho maviri. Nhanho yekutanga ndeye UV pre-curing, uye nhanho yechipiri ndeyekupisa kupisa, iyo inosarudza yekupedzisira kuita kweinki. Naizvozvo, iyo yekupisa yekurapa paramita inofanirwa kuisirwa zvinoenderana nematanho anodiwa muhunyanzvi bhuku rinopihwa nemugadziri weinki. Kana paine shanduko mukugadzirwa chaiko, unofanirwa kutanga wabvunza mugadziri weinki kana zvichiita.
Pamberi pekupisa kupisa, mapuranga haafaniri kuiswa:
Iyo inkjet inodhinda inki inongogara isati yapora isati yapora kupisa, uye kunamatira kwakashata, uye mahwendefa ane laminated anounza kukwesha kwemagetsi, izvo zvinogona kukonzera kukanganisa hunhu nyore. Mukugadzirwa chaiko, matanho anonzwisisika anofanirwa kutorwa kuderedza kukwenya kwakananga uye kukwenya pakati pemahwendefa.
Vashandi vanofanira kuenzanisa mashandiro:
Vashandi vanofanirwa kupfeka magirovhosi panguva yebasa kudzivirira kusvibiswa kwemafuta kubva pakusvibisa bhodhi rekugadzira.
Kana bhodhi ikawanikwa yakasvibiswa, kudhinda kunofanira kusiiwa.

Kugadziriswa kweinki yekurapa ukobvu
Mukugadzirwa chaiko, mavara mazhinji anodonha nekuda kwekukweshana, kukwenya kana kukanganisa kwe stack, saka kudzikisira ukobvu hwekupora kweinki kunogona kubatsira mavara kudonha. Iwe unogona kazhinji kuedza kugadzirisa izvi kana mavara ari kudonha uye ona kana paine kuvandudzwa.
Kuchinja ukobvu hwekurapa ndiko chete kugadzirisa kunoitwa nemugadziri wemidziyo kumudziyo wekudhinda.

Pesvedzero ye stacking uye kugadzirisa mushure mekudhinda mavara
Muchiitiko chinotevera chekupedzisa maitiro ehunhu, bhodhi richavawo nematanho akadai sekutsikirira kupisa, kubata kumeso, gongi, uye V-kucheka. Aya maitiro akadai se stacking extrusion, friction uye mechanical processing stress ine zvakakosha paunhu hwekudonha, izvo zvinowanzoitika Chikonzero chekupedzisira chechimiro chinodonha.
Mukuferefeta chaiko, hunhu hunodonha chiitiko chatinowanzo kuona chiri pane yakaonda solder mask pamusoro nemhangura pazasi pePCB, nekuti ichi chikamu che solder mask chakatetepa uye kupisa kunofambisa nekukurumidza. Ichi chikamu chichadziyiswa zvakakurumidza, uye chikamu ichi chinowanzoita kuti chigadzirise kushungurudzika. Panguva imwecheteyo, chikamu ichi ndicho chepamusoro convexity pane yese PCB board. Kana mabhodhi anotevera akarongedzerwa pamwechete kuitira kupisa kupisa kana kucheka, Zviri nyore kuita kuti mamwe mavara atyoke nekudonha.
Munguva yekupisa yekutsikirira, kufuratira uye kugadzira, iyo yepakati pad spacer inogona kuderedza kudonha kwehunhu kunokonzerwa nekudzvanya friction, asi iyi nzira yakaoma kusimudzira mukuita chaiko, uye inowanzo shandiswa kuenzanisa bvunzo kana uchiwana matambudziko.
Kana iyo pakupedzisira yakatemwa kuti chikonzero chikuru hunhu hunodonha hunokonzerwa nekukweshana kwakaoma, kukwenya uye kushushikana mudanho rekugadzira, uye mhando uye maitiro eiyo solder mask inki haigoni kuchinjwa, mugadziri weinki anogona kungoigadzirisa zvachose. kutsiva kana kuvandudza ingi yemavara. Dambudziko rekushaikwa kwemavara.
Zvese mune zvese, kubva pane zvabuda uye ruzivo rwevagadziri vedu vemidziyo uye vanogadzira ingi munguva yakapfuura yekuferefeta nekuongorora, mavara akadonhedzwa anowanzo hukama nemaitiro ekugadzira pamberi uye mushure mekunyora kwechinyorwa, uye ivo vane hanya kune mamwe mainki ehunhu. Kana dambudziko rekudonha kwehunhu rikaitika mukugadzirwa, chikonzero chekusagadzikana chinofanira kuwanikwa nhanho nhanho zvichienderana nekuyerera kwemaitiro ekugadzira. Tichitarisa kubva kuindasitiri yekushandiswa kwedata kwemakore mazhinji, kana ingi dzakakodzera hunhu uye kutonga kwakakodzera kwemaitiro akakodzera ekugadzira zvisati zvashandiswa uye mushure mekushandiswa, dambudziko rekurasikirwa nehunhu rinogona kudzorwa zvakanaka uye kusangana zvizere negoho reindasitiri uye zvemhando yepamusoro zvinodiwa.
