Ngophuhliso olukhawulezayo lweshishini le-elektroniki, PCB Iingcingo ziya ziba ngokuchanekileyo ngakumbi. Uninzi lwabavelisi be-PCB basebenzisa ifilimu eyomileyo ukugqibezela ukuhanjiswa kwemizobo, kwaye ukusetyenziswa kwefilimu eyomileyo kuya kusanda. Nangona kunjalo, kwinkqubo yenkonzo emva kokuthengisa, ndisahlangana nabathengi abaninzi abenza iimpazamo ezininzi xa besebenzisa ifilimu eyomileyo.

Okokuqala, kuvela imingxunya yemaski eyomileyo

Abathengi abaninzi bacinga ukuba, emva komngxunya owaphukileyo, kufuneka bandise ubushushu befilimu kunye noxinzelelo, kwaye bandise amandla abo okubopha, eneneni olu hlobo lwembono aluchanekanga, kuba emva kobushushu obuphezulu kunye noxinzelelo, umhlwa onganyangekiyo we-solvent volatilization, yenza ifilimu eyomileyo sincinci kwaye sisesichengeni sokophuka emngxunyeni xa sikhula, sihlala sifuna ukugcina ukomelela kwefilimu eyomileyo, ke, emva komngxunya owaphukileyo, sinokukwenza kula manqaku alandelayo ukuphucula:

1, ukunciphisa ubushushu bhanyabhanya kunye noxinzelelo

2, ukuphucula ukubhola ngaphambili

3, ukuphucula amandla okuveza

4, ukunciphisa ukukhula koxinzelelo

5, ixesha lokupaka emva kokuba umboniso bhanya-bhanya alinakuba lide kakhulu, ukuze ungakhokeleli kwikona yefilimu engamanzi ephantsi kwentshukumo yokusasazeka koxinzelelo

6, musa ukolula ifilimu eyomileyo engqongqo kwinkqubo yefilimu

Isibini, ifilimu eyomileyo yokwaleka kwenzeka ngaphakathi

Isizathu sokungena ngaphakathi kukuba ifilimu eyomileyo kunye nefoyile enxitywe ubhedu ayibophelelwanga, eqinisa isisombululo seplating kwaye iqinise “isigaba esingalunganga” kwinxalenye yokwaleka. Ukungena ngaphakathi kwenzeka ikakhulu kubavelisi bePCB ngenxa yezi zizathu zilandelayo:

1. Amandla aphezulu okanye aphantsi okubhengeza

Ngaphantsi kokukhanya kwe-ultraviolet, i-photoinitiator efunxa amandla okukhanya iyabola ibe yi-radical simahla ukuqala i-monomer kwi-photopolymerization reaction, yenze i-molecule yomzimba enganyibiliki kwisisombululo se-alkali. Xa ukuvezwa kungonelanga, ngenxa yokungagqitywa kwepolymer, kwinkqubo ekhulayo, ukudumba kwefilimu kuye kuthambe, kukhokelele kwimigca engacacanga kwaye nomaleko wefilimu uyawa, ukhokelela kwindibaniselwano engeyiyo yefilimu kunye nobhedu; Ukuba ukubhengeza kugqithisile, kuya kubangela ubunzima ekuphuhliseni, kwaye kuya kuvelisa ukujija kunye nokuhluba kwinkqubo yokulingisa, ukwenza ukungena ngaphakathi. Ke kubalulekile ukulawula amandla okuveza.

2. Ubushushu befilimu buphezulu okanye buphantsi

Ukuba iqondo lobushushu umboniso liphantsi kakhulu, ngenxa ifilimu ukumelana umhlwa akakwazi ukufumana ukuthamba ngokwaneleyo kunye nokuhamba efanelekileyo, okubangela adhesion amahlwempu phakathi owomileyo umboniso nobhedu egqunywe umphezulu laminate; Ukuba iqondo lobushushu liphezulu kakhulu ngenxa yokonyuka okukhawulezileyo kwesinyibilikisi kunye nezinye izinto ezinokuxhathisa kunye namaqamza, kwaye ifilimu eyomileyo iba brittle, yenza i-warping peel xa ityhafisa ngombane, kukhokelela kukungena ngaphakathi.

3. Uxinzelelo lwefilimu luphezulu okanye luphantsi

Xa uxinzelelo lwefilimu luphantsi kakhulu, kunokubangela umphezulu ongalinganiyo wefilimu okanye umsantsa phakathi kwefilimu eyomileyo kunye nembasa yobhedu kwaye ungahlangabezani neemfuno zamandla okubopha; Ukuba uxinzelelo lwefilimu luphezulu kakhulu, izinyibilikisi kunye nezinto ezingahambelaniyo zomaleko wokubulala ungazinzi, nto leyo ikhokelela kwifilimu eyomileyo, eya kuthi emva koko yothuke emva kokutyabeka.
