The PCB ibhodi sivame ukubona inemibala eminingi. Eqinisweni, le mibala yenziwa ngokuphrinta imaski ye-solder ye-PCB ehlukene. Imibala evamile ku-PCB circuit board solder mask iluhlaza, emnyama, ebomvu, eluhlaza okwesibhakabhaka, emhlophe, ephuzi, njll. Abantu abaningi banelukuluku lokufuna ukwazi, uyini umehluko phakathi kwala mabhodi wesifunda ahlukene?

Kungakhathaliseki ukuthi ibhodi lesifunda entweni kagesi, i-motherboard yeselula noma i-motherboard yekhompyutha, amabhodi wesekethe e-PCB asetshenziswa. Ngokombono wokubukeka, amabhodi esekethe e-PCB eza ngemibala ehlukahlukene, okuluhlaza kuvame kakhulu, kulandele okuluhlaza okwesibhakabhaka, obomvu, omnyama, omhlophe njalonjalo.

Kungakhathaliseki ukuthi umbala onjani ibhodi lesifunda lenombolo efanayo yezinto ezibonakalayo, umsebenzi walo uyafana. Amabhodi wesifunda anemibala ehlukene abonisa ukuthi umbala we-solder mask osetshenzisiwe uhlukile. Umsebenzi oyinhloko we-mask ye-solder ukuyibeka ku-mask ye-solder ukumboza izintambo ukuze zifake insulate futhi zivimbele izifunda ezimfushane. Uhlaza luvame ukubonakala, ngoba wonke umuntu usetshenziselwa ukusebenzisa inki ye-mask ye-solder eluhlaza kumabhodi wesifunda, futhi abakhiqizi bemaski be-solder ngokuvamile bakhiqiza amafutha amaningi aluhlaza, futhi izindleko zizoba ngaphansi kunabanye oyinki bombala. , Cishe zonke zisesitokweni. Yiqiniso, amanye amakhasimende azodinga neminye imibala, njengomnyama, obomvu, ophuzi, njll, ngakho-ke adinga ukuphrinta ngeminye imibala ye-solder mask.

Uyinki ebhodini lesifunda le-PCB, ngokujwayelekile, kungakhathaliseki ukuthi umbala we-solder mask, indima yawo ayihlukile kakhulu. Umehluko omkhulu umehluko obonakalayo. Ngaphandle kombala omhlophe osetshenziswa ku-aluminium substrate kanye nokukhanya kwangemuva, kuzoba nomehluko othile ekukhanyeni kokukhanya, futhi eminye imibala isetshenziselwa ukuvikela i-solder nokuvikela ukufakwa kwe-insulation.

Amamaski e-solder emibala ehlukene aphrintiwe ebhodini lesifunda. Nakuba umehluko wokusebenza ungemkhulu, kusenomehluko omncane. Okokuqala ukuthi kubonakala kuhlukile. Ngokunganaki, nginomuzwa wokuthi okumnyama nokuluhlaza okwesibhakabhaka kusezingeni eliphezulu, futhi izidingo zizoba phezulu. Kodwa-ke, amabhodi wesifunda asebenzisa imaski ye-solder eluhlaza ajwayelekile kangangokuthi azizwa evame kakhulu. Amaphaneli amaningi angawodwa asebenzisa imaski ye-solder eluhlaza. Uma kuqhathaniswa nomnyama, akulula ukubona iphethini yomugqa, futhi ukumboza kuzoba ngcono, okungavimbela ukukopisha kontanga ngezinga elithile. Okumhlophe kukhombisa ukukhanya kangcono, futhi ngokuvamile kusetshenziselwa ukukhanyisa noma ukukhanyisa ngemuva.

Iningi lamamaski e-solder asetshenziswa kumabhodi wesekethe aluhlaza, futhi imaski ye-solder esetshenziswa kumabhodi we-antenna aguquguqukayo weselula ikakhulukazi amnyama nokumhlophe. Ibhodi lezintambo kanye nebhodi lemojula yekhamera ngokuvamile lisebenzisa uyinki ophuzi we-solder resist, futhi ibhodi yebha ekhanyayo isebenzisa uyinki wokuphikisa omhlophe noma omhlophe we-matt.

Ngokuvamile, yimuphi umbala solder ukumelana inki esetshenziswa PCB kuncike ikakhulukazi izidingo ikhasimende ifektri ibhodi wesifunda. Umbala awunawo umthelela omningi ekusebenzeni. Okuncane ukuthi uma i-photosensitive solder resist inki isetshenziswa, ngokuvamile kulula ukuba mhlophe. Ngaphandle kwesici sefilimu. Ebhodini lesifunda eliguquguqukayo, imaski ye-solder emhlophe imelana kancane nokugoba kuneminye imibala.

Kukhona futhi imaski ye-solder kumabhodi wesifunda anemibala ekhethekile. Eziningi zalezi zimaski ze-solder zombala ezikhethekile zilungiswa abakhiqizi be-inki, kanti ezinye zixubene nezinhlobo ezimbili zamayinki e-solder mask ngesilinganiso esithile. Ihlanganisiwe (ezinye izimboni ezinkulu zebhodi lesifunda, i-blender yamafutha ngaphakathi izolungisa umbala)

Kungakhathaliseki ukuthi uyinki yombala we-PCB solder ukumelana, kufanele ibe nokuphrinta okuhle nokulungiswa, ukuze ihlangabezane nezidingo zesikrini sikasilika kanye nezidingo zokukhiqiza zefekthri.
