9. Yintoni isisombululo? Impendulo: Kumgama we-1mm, isisombululo semigca okanye imigca yezithuba enokuthi yenziwe ngokumelana nefilimu eyomileyo inokubonakaliswa ngobungakanani obupheleleyo bemigca okanye izithuba.Umahluko phakathi kwefilimu eyomileyo kunye ne-resistance film thickness Ubukhulu befilimu ye-polyester bunxulumene.Ukuqina komgangatho wefilimu ochasayo, ukuncipha kwesisombululo.Xa ukukhanya kudlula ipleyiti yeefoto kunye nefilimu ye-polyester kunye nefilimu eyomileyo ibonakaliswe, ngenxa yokusabalalisa ukukhanya ngefilimu ye-polyester, i-lighter side Ngokungqongqo, isisombululo esisezantsi. 
10. Yintoni i-etching resistance kunye ne-electroplating resistance ye-PCB eyomileyo ifilimu? Impendulo: I-etching resistance: Ifilimu eyomileyo yokumelana nongqimba emva kwe-photopolymerization kufuneka ikwazi ukumelana ne-etching ye-iron trichloride etching solution, isisombululo se-persulfuric acid etching, i-acid chlorine, isisombululo se-copper etching, i-sulfuric acid-hydrogen peroxide etching solution.Kwisisombululo se-etching esingentla, xa iqondo lokushisa li-50-55 ° C, ubuso befilimu eyomileyo kufuneka bube bukhululekile kwizinwele, ukuvuza, ukulwa nokuchithwa.Ukumelana ne-Electroplating: kwi-acidic ekhanyayo yobhedu, i-fluoroborate yealloyi eqhelekileyo, i-fluoroborate ekhanyayo ye-tin-lead alloy plating kunye nezisombululo ezahlukahlukeneyo zangaphambili ze-electroplating, ifilimu eyomileyo ixhathisa umaleko emva kokwenziwa kwepolymerization akufuneki ingabinanwele ngaphezulu. . 11. Kutheni umatshini wokubonisa kufuneka ufunxe ivacuum xa uveza? Impendulo: Kwimisebenzi ye-non-collimated light exposure (oomatshini be-exposure kunye "namanqaku" njengomthombo wokukhanya), iqondo lokufunxa i-vacuum yinto ephambili echaphazela umgangatho wokuvezwa.Umoya ukwangumaleko ophakathi., Kukho umoya phakathi kwefilimu yokukhupha umoya, ngoko iya kuvelisa ukukhanya okukhanyayo, okuya kuchaphazela umphumo wokuvezwa.I-vacuum ayikuko nje ukuthintela ukuguqulwa kokukhanya, kodwa nokuthintela umsantsa phakathi kwefilimu kunye nebhodi ekukhuliseni, kunye nokuqinisekisa ukulungelelaniswa / Umgangatho wokuvezwa.
12. Ziziphi iingenelo zokusebenzisa ipleyiti yokusila yothuthu lwentaba-mlilo xa kunyangwa? ukusilela? Impendulo: Izinto eziluncedo: a.Udibaniso lwamasuntswana omgubo wepumice abrasive kunye neebhrashi zenylon zixutywe ngetangentially ngelaphu lekotoni, elinokuthi lisuse lonke ukungcola kwaye liveze ubhedu obutsha kunye obusulungekileyo;b.Iyakwazi ukwenza i-sand-grained ngokupheleleyo, i-rough and uniform D. Umphezulu kunye nomngxuma awuyi konakaliswa ngenxa yempembelelo yokuthambisa ye-nylon brush;d.Ukuguquguquka kwebrashi yenayiloni ethambileyo kunokwenza ingxaki yomgangatho wepleyiti engalinganiyo ebangelwa kukunxitywa kwebrashi;e.Ekubeni i-plate surface ifana kwaye ingenayo i-grooves, ukuchithwa kokukhanya kwe-exposure kuyancipha, ngaloo ndlela kuphuculwe isisombululo somfanekiso.Ukungalungi: Ukungalungi kukuba i-pumice powder kulula ukuyonakalisa iindawo zomatshini zezixhobo, ukulawulwa kokusabalalisa ubungakanani be-particle ye-pumice powder kunye nokususwa kwe-pumice powder intsalela phezu komhlaba we-substrate (ngokukodwa kwimingxuma. ).
13. Yintoni eya kuthi ibhodi yesekethe iphuhlise iphoyinti ibe nkulu kakhulu okanye incinci kakhulu? Impendulo: Ixesha elichanekileyo lophuhliso lichongwa ngendawo yophuhliso (indawo apho ifilimu eyomileyo engabonakaliyo isuswe kwibhodi eprintiweyo).Indawo yophuhliso kufuneka igcinwe kwipesenti engatshintshiyo yobude obupheleleyo becandelo lophuhliso.Ukuba indawo ephuhlisayo isondele kakhulu ekuphumeni kwecandelo eliphuhlisayo, ifilimu yokumelana ne-polymerized ayiyi kuhlanjululwa ngokwaneleyo kwaye iphuhliswe, kwaye i-residu yokuxhathisa inokuhlala phezu kwebhodi kwaye ibangele uphuhliso olungcolileyo.Ukuba indawo yokuphuhlisa isondele kakhulu ekungeneni kwecandelo eliphuhlisayo, ifilimu eyomileyo eyenziwe ngepolymer inokuthi ifakwe yi-Na2C03 kwaye ibe noboya ngenxa yoqhagamshelwano olude kunye nesisombululo esiphuhlisayo.Ngokuqhelekileyo indawo yokuphuhlisa ilawulwa ngaphakathi kwe-40% -60% yobude obupheleleyo becandelo lokuphuhlisa (35% -55% yenkampani yethu). 14. Kutheni le nto kufuneka siyibhake kwangaphambili ibhodi ngaphambi kokuba abalinganiswa baprintwe? Impendulo: Ibhodi ebhakiweyo ngaphambili a kukwandisa amandla okudibanisa phakathi kwebhodi kunye nabalinganiswa phambi kokuba abalinganiswa baprintwe, kwaye b ukuqinisa ubulukhuni be-inki yemaski ye-solder kumphezulu webhodi ukunqanda i-solder mask oil cross. -Ukusasazwa okubangelwa kushicilelo lweempawu okanye ukuqhubekeka okulandelayo. 15. Kutheni kufuneka sijiwule ibrashi yomatshini wokusila ipleyiti yonyango lwangaphambili? Impendulo: Kukho umgama othile phakathi kweentsimbi ze-brush pin.Ukuba awusebenzisi i-sway ukugaya ipleyiti, kuya kubakho iindawo ezininzi ezingayi kunxitywa, okukhokelela ekucoceni okungalinganiyo kwendawo yeplate.Ngaphandle kokugungqa, i-groove ethe tye iya kwenziwa kwindawo yeplate.Ibangela ukuqhekeka kocingo, kwaye kulula ukuphula imingxuma kunye nokuvelisa isenzeko somsila ngaphandle kokuguqula umda womngxuma. 16. I-squeegee idlala ntoni ekushicileleni? Impendulo: I-angle ye-squeegee ilawula ngokuthe ngqo inani leoli, kwaye ukufana kwe-blade kumphezulu kuchaphazela ngokuthe ngqo umgangatho ophezulu wokushicilela. 17. Ziziphi iimpembelelo zemaski ye-solder kunye nobushushu kunye nokufuma kwindawo emnyama kwimveliso ye-PCB? Impendulo: Xa iqondo lokushisa kunye nomswakama kwigumbi elimnyama liphezulu kakhulu okanye liphantsi kakhulu: 1. Kuya kwandisa inkunkuma emoyeni, 2. Ifilimu yokunamathela isiganeko kulula ukuvela kwi-alignment, 3. Kulula ukubangela ukuba ifilimu ukukhubaza, 4. Kulula ukubangela umphezulu webhodi ukuba oxidize. 18. Kutheni i-solder imaski ingasetyenziswa njengendawo yokuphuhlisa? Phendula "Ngenxa yokuba kukho izinto ezininzi eziguquguqukayo kwiinki zemaski ze-solder. Okokuqala, iindidi zee-inki zinzima ngakumbi kwaye zinzima. Iipropati ze-inki nganye ziyahluka. Ngexesha lokuprinta, ubukhulu bebhodi nganye ye-inki iya kubangela ukufana ngenxa ye Impembelelo yoxinzelelo, isantya kunye ne-viscosity. Azifani nefilimu eyomileyo. Ubunzima befilimu enye bufana kakhulu. Ngelo xesha, i-inki yokuxhathisa i-solder iphinda ichaphazeleke ngexesha lokubhaka elahlukileyo, ubushushu, kunye nokuvezwa kwamandla. Ngexesha lenkqubo yokuvelisa Isiphumo sebhodi siyafana Ngoko ke ukubaluleka kokusebenza kwe-solder mask njengendawo yophuhliso ayinkulu.
