Izinkinga ezivamile nezinyathelo zokulwa nazo I-FPC futhi PCB inqubo yokukhiqiza

Ngokuguqulwa kobuso bensimbi bube wuhlobo olungenamthofu, ibhodi lesifunda le-PCB lidinga ukuthwala ukushisa kwe-ultra-high, futhi isidingo sokumelana nokushaqeka okushisayo kwangaphandle kwensimbi yokumelana nendawo kuphakeme futhi kuphakeme. Isidingo sokwelashwa kwendawo yokugcina, amandla wokuxebuka wesendlalelo sokumelana nesinki (uyinki, ifilimu yokufihla ubuso) nokunamathela nge-base yethusi kuphakeme futhi kuphakeme. Sidinga ubuchwepheshe obungaphambi kokwelashwa ukuze kuqinisekiswe. Ngokwenza ngcono ubuchwepheshe bethu, singathuthukisa isivuno sezimpahla futhi sifinyelele ekukhuleni kwenzuzo. Ikhambi eliphakeme langaphambi kokwelashwa ngokungangabazeki lingasisiza ngentengo ephansi.

Le ndatshana yethula ikakhulukazi imibuzo nama-Countermeasure avame ukubhekana nawo kwinqubo yokukhiqizwa kwebhodi lesifunda elithambile le-PCB ne-FPB: okokuqala, isigaba somugqa siveza ukuguguleka kohlangothi nokubukeka kwe-concave lapho kudonswa umugqa ngemuva kwefilimu eyomile noma ukwelashwa kwefilimu emanzi, okuholela ekushodweni komugqa ububanzi noma umugqa ongalingani. Isizathu asilutho ngaphandle kokukhetha okungafanele kwemininingwane yefilimu eyomile neyamanzi, imingcele yokuvezwa okungalungile nokusebenza kabi komshini wokuchayeka. Ukuthuthuka, ukufakwa kwesigaba somlomo wombhobho, isimo esingenangqondo samapharamitha ahlobene, ukugxila okungafanele kanye nesikali semithi ewuketshezi, isivinini sokudlulisa okungafanele nolunye uchungechunge kungadala imibuzo. Kodwa-ke, sivame ukuthola ukuthi akukho okungajwayelekile ngokubheka imingcele engenhla nemisebenzi yokusebenza ehlobene, kepha kusenemibuzo efana nokugqwala nokugqwala kwe-concave kwebhodi lesifunda lapho kwenziwa ibhodi. Siyini isizathu ngemuva kwakho konke?

2, Uma wenza i-PCB iphethini ye-electroplating nokwelashwa kwendawo ye-PCB ne-FPC terminals, njengokufakwa kwegolide, igolide kagesi, ithini kagesi, amathini amakhemikhali nokunye ukwelashwa kwezobuchwepheshe, sivame ukuthola ukuthi amabhodi akhiqizwayo akhombisa ukuvela kokungena kokungena emaphethelweni yefilimu eyomile futhi emanzi noma ungqimba lwe-solder resist, noma iningi lamabhodi noma amanye amabhodi endawo, Akunandaba ukuthi hlobo luni lwesimo, luzoletha ukwesulwa noma ukukhubazeka okungadingekile, inkathazo engadingekile yokwenza okuthunyelwe, ngisho nokukhanselwa ekugcineni , okubuhlungu! Isizathu ukuthi imvamisa sicabanga ngemingcele yefilimu eyomile neyamanzi, futhi umsebenzi wedatha ungabazekile; Kunemibuzo mayelana nokumelana ne-solder, njengoyinki webhodi elukhuni, imasking film yebhodi elithambile, noma imibuzo ekuphrinteni, ngokucindezela, ekwelapheni nakwezinye izingxenye. Ngempela, ngayinye yalezi zindawo ingadala lokhu kungabaza. Ngemuva kwalokho siphinde sidideke ukuthi akukho kungabaza noma ukungabaza esigabeni esingenhla esingenhla, kepha kusazokhombisa ukuvela kokungena kokungena. Ngemuva kwakho konke, yini isizathu sokungatholi?

3, amabhodi e-PCB azohlolwa ngothayela ngaphambi kokuthunyelwa. Vele, amakhasimende azosebenzisa izingcezu ze-tin eziphothene. Akungabazeki ukuthi uyinki ungacwecwa kakhulu noma ukuthi amandla wokuxebula wefilimu yokufihla inamba yepuleti elithambile ayinawo noma awalingani, Amakhasimende, ikakhulukazi lawo enza kahle ukukhishwa kwe-SMT, awanakuyithwala le mibuzo. Lapho ungqimba lwe-solder resist luveza ukuvela kokukhanya kokukhanya ngesikhathi sokushisela, kuzokwenza ukuthi kungabi lula ukufaka kahle okwangempela, okuholele ekulahlekelweni kwezakhi eziningi nokubambezeleka komsebenzi ngamakhasimende. Ifektri yebhodi lesifunda izobhekana nokulahleka okukhulu njengokuncishiswa, ukwesekwa kwezinto ezibonakalayo, kanye nokulahleka kwamakhasimende. Ngakho-ke yiziphi izici esivame ukuqala ngazo lapho sihlangana nemibuzo enjalo? Sivame ukuhlaziya ukuthi ingabe iyidatha yokulwa (eyinki, yokufihla ifilimu) yedatha; Ngabe kukhona ukungabaza ngesikhathi sokuphrinta kwesilika, ukuvikela nokwelapha; Ngabe kukhona ukungabaza mayelana ne-potroplating potion? linda… Ngakho-ke, sivamise uku-oda onjiniyela ukuthola isizathu nokuthuthuka kusuka kulezi zingxenye. Siyazibuza futhi ukuthi ngabe yisimo sezulu na? Kumanzi nje muva nje, futhi ibhodi limunca umswakama? (I-PCB substrate nesithiyo kulula ukuncela umswakama) ngokusebenza kanzima, kungavuna imiphumela ethile. Akungabazeki ukuthi bazophathwa ngaphandle okwamanje okwamanje.
