PCB solder ink kukura

Kuti uvandudze hunyoro hwekushomeka uye kudzivirira kukuvara kwezvikamu izvo zvisingade kuvezwa panguva yekugadzirwa kwePBB, zvikamu izvi zvinofanirwa kuchengetedzwa neyakavhara inki. Iko kuvandudza kwePBBinki kwakabatana zvakanyanya nemidziyo tekinoroji, mamiriro ekumonera uye zvido zvemutsara. Iine iyo yepamusoro-density density PCB uye nechitarisiko chemutobvu-isina waya yekutengesa tekinoroji, zvitsva zvinodiwa zvinoiswa kumberi kune diluent kugadzirisa inki viscosity uye kuiita inosangana nezvinodiwa zveingi jet yekudhinda inonamira solder inki. Pcb solder ink ine nhanho ina dzekusimudzira, kubva kune yekutanga yakaoma firimu mhando uye thermosetting mhando zvishoma nezvishoma zvakagadziriswa kuenda ku ULTRAVIOLET (UV) mwenje wekugadzirisa mhando, uye ndokuzoonekwa semifananidzo ichigadzira solder inki.

1. Yakaderera viscosity inogona kunge ink-jet yekutengesa inki

Nekuvandudzwa kwemaindasitiri emagetsi, yakazara izere tekinoroji yemagetsi ine yekuwedzera nzira inobuda panguva chaiyo. Kuwedzera nzira maitiro ine zvakanakira kuchengetedza zvinhu, kuchengetedza kwezvakatipoteredza, maitiro akareruka, nezvimwe. Nekuda kwekushandisa kwayo inkjet kudhinda senzira huru yehunyanzvi, pane zvitsva zvinodiwa zvezvinhu zveinki nemidziyo yemuviri, zvinonyanya kuratidzwa se:

(1) kudzora ingi viscosity, kuverengera kuti inogona kumwayiswa zvichiramba kuburikidza kamwene, kudzivirira plug kuti isangane

(2) kudzora kurapa kwekumhanyisa mhanyisa, kuzadzisa nekukurumidza kutanga kwakasimba, kudzivirira inki muiyo substrate nekuda kwekupinda nekupararira;

(3) Chinja inki thixotropy kuona mhando uye kudzokorora kwetambo yekudhinda. Zvekuvandudzwa kweiyo yakaderera viscosity solder inki, iko kushandiswa kukuru kwechinyakare solder zvinhu nadzurudzo, inowedzerwa neanoshanda kana asingaite degree degree rinodiwa.

2. FPC yekutengesa inki

With kukura pcb indasitiri, kudiwa FPC inokura nokukurumidza, uye zvinodiwa itsva vanoiswa mberi runoenzanirana zvinhu. Nekuti iyo waya yemhangura pane flexo ndiro iri nyore kuisa oxidize, iyo yekumisikidza kuramba zvinhu zve flexo mhangura waya yave yekutsvagisa hotspot. Iyo yechinyakare epoxy kuramba firimu inoratidza kukwirira brittleness mushure mekurapa uye haina kukodzera kuchinjika. Naizvozvo, kiyi yekugadzirisa dambudziko kuunza inochinjika cheni chidimbu mune yechinyakare nebwe chimiro uye chengetedza kwekutanga kuramba kutenderera kwekutenderera. Ingi ine kugadzikana kwakanaka kwekuchengetedza, inogona kunyungudika musodium carbonate solution, ammonia solution, ichirapa mafirimu makanika, chafariz, asidhi uye alkali ngura zvimiro zvinosangana nezvinodiwa.

3. Mvura-inogadziriswa alkali kuvandudza mafoto solder inki

Kuti kuderedze kuburitswa kwe organic solvents muPCB yekugadzira maitiro uye kudzikisira kukanganisa kwezvinyungudika pane zvakatipoteredza, solder ichivharira inki yakagadziriswa zvishoma nezvishoma kubva ku organic solvent yekuvandudza maitiro ekudzora alkaline mvura yekuvandudza, uye mumakore achangopfuura, yakagadzira kunwisa kuvandudza tekinoroji. Panguva imwecheteyo, kuitira kuti usangane nezvinodiwa zvemuchina wekutungamira-wakasununguka wekurwisa firimu, kunatsiridza kushomeka kune yakanyanya tembiricha kuita.

4. LED ine yakakwira kuratidzwa chena solder inki

TaiyoInk yakatanga kuratidza yayo chena solder ichivharira inki ye LED kurongedza muna 2007. Inofananidzwa neyechinyakare solder inki, chena solder inki inoda kugadzirisa matambudziko ekuparara uye nekukurumidza kukwegura kunokonzerwa nekureba-kwenguva kuratidzwa kune mwenje sosi. Yetsika epoxy solder inki nekuda kwema molecular mamiriro ane benzene mhete, mwenje wenguva refu uri nyore kukonzera kushanduka. Kune LED mwenje sosi, solder yekudzivirira kupfeka yakaputirwa pazasi pezvinhu zvekuvhenekera, saka zvinodikanwa kuti uvandudze kuratidzwa kwekushongedzwa kweiyo solder kuramba kupfeka kuchiedza, uyezve kusimudzira kupenya kwechiedza sosi. Izvi zvinopa chinetso chitsva kutsvagurudzo yemidziyo yekumonera zvinhu.

mhedziso

Tsvagurudzo yeinki yekusungira inogara iri nguva yakaoma muPCB indasitiri. Nedunhu rekudhinda kubva pakubvisa nzira zvishoma nezvishoma kusvika pakuwedzera nzira, inkjet kudhinda senzira huru yehunyanzvi yekuwedzera maitiro, iyo viscosity ye solder inki, thixotropy uye reactivity isa kumberi zvakakwirira zvinodiwa; Kuzivikanwa kwe lead-yemahara yekutengesa tekinoroji kwaisa pamberi zvido zvitsva zvekukwirira tembiricha kusagadzikana kweiyo solder firimu, kuvandudzwa kweiyo itsva solder flux inoda nekukurumidza nhamba yakawanda yevanotsvagisa, uye kutsvagisa kweinki yekusungira kuri kuwedzera, iyo ine huru kugona.
