9. Chii chinonzi resolution? Mhinduro: Pakati pechinhambwe che1mm, kugadziriswa kwemitsara kana mitsara yepakati inogona kuumbwa neyakaoma firimu inopikisa inogonawo kuratidzwa nehukuru hwakakwana hwemitsara kana nzvimbo.Musiyano pakati pefirimu yakaoma uye kuramba firimu ukobvu Ukobvu hwefirimu repolyester hunoenderana.Iyo yakakora iyo inopikisa firimu layer, inodzika iyo resolution.Apo chiedza chinopfuura nepakati peplate yemifananidzo uye firimu repolyester uye firimu yakaoma inoratidzwa, nekuda kwekupararira kwechiedza nefirimu yepolyester, rutivi rwakareruka Seriously, yakaderera kugadzirisa. 
10. Chii chinonzi etching resistance uye electroplating resistance yePCB yakaoma firimu? Mhinduro: Etching resistance: Iyo yakaoma firimu inopikisa layer mushure mephotopolymerization inofanira kukwanisa kumira etching ye iron trichloride etching solution, persulfuric acid etching solution, acid chlorine, copper etching solution, sulfuric acid-hydrogen peroxide etching solution.Mumushonga wepamusoro we etching, kana kutonhora kuri 50-55 ° C, pamusoro pefirimu yakaoma inofanira kunge isina bvudzi, kuputika, kuputika uye kubuda.Electroplating kuramba: mune acidic inopenya yemhangura plating, fluoroborate yakajairwa lead alloy, fluoroborate inopenya tin-lead alloy plating uye akasiyana pre-plating mhinduro dzeiyo pamusoro electroplating, iyo yakaoma firimu inodzivirira layer mushure me polymerization haifanirwe kunge isina bvudzi repamusoro. . 11. Sei muchina wekuvheneka uchifanira kusveta vacuum kana uchifumura? Mhinduro: Mukushanda kwechiedza chisina-collimated (mashini ekuvhenekera ane "mapoinzi" semwenje sosi), dhigirii rekunyura kwevacuum ndicho chinhu chikuru chinokanganisa kunaka kwekuratidzwa.Mhepo zvakare iri pakati nepakati., Pane mhepo pakati pemhepo inotorwa firimu, zvino ichagadzira refraction yechiedza, iyo ichakanganisa mhedzisiro yekufumurwa.Vacuum haisi yekudzivirira kupenya kwechiedza chete, asiwo kudzivirira mukaha pakati pefirimu nebhodhi kubva pakuwedzera, uye kuve nechokwadi kurongeka / Hunhu hwekuratidzwa.
12. Ndezvipi zvakanakira kushandisa ndiro yekukuya madota anoputika pakurapa kusati kwaitwa? kuperevedza? Mhinduro: Zvakanakira: a.Iko kusanganiswa kweabrasive pumice poda zvimedu uye mabhurashi enylon anokwizwa tangentially nemucheka wekotoni, unogona kubvisa tsvina yese uye kufumura mhangura yakachena uye yakachena;b.Inogona kuumba jecha rakazara, rakashata uye yunifomu D. Nzvimbo uye gomba hazvizokuvadzi nekuda kwekunyorovesa kwebhurashi yenylon;d.Iko kuchinjika kweiyo yakapfava nylon brashi inogona kugadzirisa iyo Dambudziko rekusaenzana kweplate pamusoro inokonzerwa nekupfeka kwebhurashi;e.Sezvo chidimbu cheplate chiri yunifomu uye pasina grooves, kupararira kwechiedza chekuratidzira kunoderedzwa, nokudaro kuvandudza kugadziriswa kwekufungidzira.Kukanganisa: Izvo zvisingabatsiri ndezvokuti pumice powder iri nyore kukuvadza zvikamu zvemagetsi zvemidziyo, kutonga kwechikamu chekukura kwekugoverwa kwepumice powder uye kubviswa kwepumice powder yakasara pamusoro pe substrate (kunyanya mumakomba. )
13. Chii chichaita kuti bhodhi redunhu rikure poindi yakakurisa kana kuti diki? Mhinduro: Nguva yekuvandudza yakakodzera inotarirwa nenzvimbo yekusimudzira (nzvimbo iyo iyo isina kuvhenekwa firimu yakaoma inobviswa kubva pabhodhi rakadhindwa).Nzvimbo yekusimudzira inofanirwa kuchengetedzwa pachikamu chenguva dzose chehurefu hwese hwechikamu chekusimudzira.Kana iyo nzvimbo yekusimudzira iri pedyo zvakanyanya nekubuda kwechikamu chinokura, iyo unpolymerized resist firimu haizocheneswi zvakakwana uye yakagadziridzwa, uye iyo inopikisa inosara inogona kuramba iri pamusoro pebhodhi uye inokonzera kusachena kukura.Kana iyo nzvimbo yekusimudzira iri padhuze nepamusuwo wechikamu chiri kusimukira, iyo polymerized yakaoma firimu inogona kudhindwa neNa2C03 uye ive ine mvere nekuda kwekugara kwenguva refu nemhinduro iri kukura.Kazhinji nzvimbo yekusimudzira inodzorwa mukati me40% -60% yehurefu hwakazara hwechikamu chiri kukura (35% -55% yekambani yedu). 14. Nei tichifanira kufanobika bhodhi mavara asati adhindwa? Mhinduro: Iyo pre-yakabikwa bhodhi a ndeyekuwedzera simba rekubatanidza pakati pebhodhi uye mavara mavara asati adhindwa, uye b kuwedzera kuoma kweiyo solder mask inki pamusoro pebhodhi kudzivirira solder mask mafuta muchinjiko. -kupararira kunokonzerwa nekudhindwa kwehunhu kana kuteedzera kugadzirisa. 15. Nei tichifanira kupenengura bhurasho remuchina wokukuya ndiro? Mhinduro: Pane imwe chinhambwe pakati pebhurashi pini reels.Kana iwe usingashandisi kusvetwa kukuya ndiro, pachava nenzvimbo dzakawanda dzisingapfeki, zvichiita kuti pave nekucheneswa kusina kuenzana kweplate.Pasina kuzununguka, groove yakatwasuka ichaumbwa pamusoro peplate.Inokonzeresa kutsemuka kwewaya, uye zviri nyore kupaza maburi uye kuburitsa chiitiko chemuswe pasina kutenderedza mupendero wegomba. 16. Chii chinoita kuti squeegee iite pakudhinda? Mhinduro: Iko kona ye squeegee inodzora zvakananga kuwanda kwemafuta, uye kufanana kweblade kusvika kumusoro kunobata zvakananga pamusoro pehutano hwekudhinda. 17. Ndezvipi zvinokonzeresa solder mask uye tembiricha uye mwando murima mukamuri pamusoro PCB kugadzirwa? Mhinduro: Kana kutonhora uye hunyoro muimba yerima zvakanyanyisa kana kuti zvakaderera: 1. Ichawedzera marara mumhepo, 2. Iyo firimu inonamatira chiitiko chiri nyore kuonekwa mukurongeka, 3. Zviri nyore kukonzera iyo firimu kuti deform, 4. Zviri nyore kukonzera bhodhi pamusoro kuti oxidize. 18. Neiko solder mask isingashandiswe sechinhu chinokura? Pindura "Nekuti pane zvakawanda zvakasiyana-siyana mu solder mask inks. Chokutanga pane zvose, marudzi einki anowedzera uye akaoma. Zvinhu zveinki imwe neimwe zvakasiyana. Panguva yekudhinda, kukora kwebhodhi imwe neimwe kuchaita kuti pave nekufanana nekuda kwe Kupesvedzera kwekumanikidza, kumhanya uye viscosity. Izvo hazvina kufanana neyakaoma firimu. Ukobvu hwefirimu rimwechete hwakanyanya kufanana. Panguva imwecheteyo, iyo solder inopikisa inki inobatwawo nenguva dzakasiyana dzekubheka, tembiricha, uye kuratidzwa simba. panguva yekugadzira.Kuita kwebhodhi kwakafanana.Saka kukosha kwekuita kwe solder mask senzvimbo yekusimudzira hakuna kunaka.
