Iiibhodi zesekethe PCBsihlala sibona ukuba nemibala emininzi.Enyanisweni, le mibala zonke zenziwe ngoshicilelo ezahlukeneyo PCB solder ukumelana inki.Imibala eqhelekileyo kwibhodi yesekethe ye-solder ye-PCB yokuxhathisa i-inks eluhlaza, emnyama, ebomvu, eblue, emhlophe, etyheli, njl. Abantu abaninzi banomdla wokwazi, yintoni umahluko phakathi kwezi bhodi zesekethe ezinemibala eyahlukeneyo?
Nokuba yibhodi yesekethe kwisixhobo sombane, i-motherboard yefowuni ephathwayo okanye i-motherboard yekhompyuter, zonke zisebenzisa iibhodi zesekethe zePCB.Ukusuka kwindawo yokujonga, iibhodi zesekethe zePCB zinemibala eyahlukeneyo, eluhlaza ixhaphake kakhulu, ilandelwa yiblue, ebomvu, emnyama, emhlophe njalo njalo.
Iibhodi ezinenombolo yenxalenye efanayo zinomsebenzi ofanayo kungakhathaliseki ukuba zinemibala enjani.Iibhodi ezinemibala eyahlukeneyo zibonisa imibala eyahlukeneyo ye-inki yokuxhathisa esetyenzisiweyo.Umsebenzi ophambili we-inki yokuxhathisa i-solder kukubeka kwi-solder resist layer ukugubungela iingcingo zokugquma kunye nokuthintela imijikelezo emfutshane.Uhlaza ludla ngokubonwa, kuba wonke umntu usetyenziselwa ukusebenzisa i-solder eluhlaza ukuxhathisa inki ukwenza iibhodi zesekethe, kunye nabavelisi be-inki yokuxhathisa i-inki ngokubanzi ukuvelisa ioli eluhlaza, kwaye iindleko ziya kuba ngaphantsi kwe-inki zeminye imibala., phantse zonke zikhoyo.Ewe kunjalo, abanye abathengi baya kufuna eminye imibala, enjengomnyama, obomvu, tyheli, njl., ekufuneka iprintwe ngee-inks zokuxhathisa zeminye imibala.
I-inki kwibhodi yesekethe ye-PCB, ukuthetha ngokubanzi, kungakhathaliseki ukuba yintoni umbala we-inki yokumelana ne-solder, umphumo wayo awufani kakhulu.Esona sizathu siphambili ngumahluko kumbono.Ngaphandle kokuba umhlophe usetyenziselwa i-aluminium substrate kunye ne-backlight, kuya kubakho umehluko othile ekubonakalisweni kokukhanya, kunye neminye imibala isetyenziselwa ukubethelwa kunye nokukhuselwa kwe-insulation.
I-Solder resistant inki zemibala eyahlukileyo ziprintwa kwibhodi yesiphaluka.Nangona kungekho mahluko ungako kumsebenzi, kusekho umahluko omncinane.Okokuqala, kubonakala kwahlukile.Ngaphantsi, ndivakalelwa kukuba umnyama kunye nohlaza okwesibhakabhaka kuphezulu, kwaye iimfuno ziya kuba phezulu.Nangona kunjalo, iibhodi zesekethe usebenzisa i-solder eluhlaza ukuxhathisa inki zixhaphake kakhulu, ngoko ziziva ziqhelekileyo.Iibhodi ezininzi ezisecaleni zisebenzisa i-inki ye-solder eluhlaza.Xa kuthelekiswa nomnyama omnyama, akulula ukubona iphethini yomgca, kwaye ukusebenza kokugubungela kuya kuba ngcono, oku kunokuthintela abalingane ukuba bakopishe ibhodi ukuya kwinqanaba elithile.Imhlophe ibonakalisa ukukhanya ngcono kwaye isetyenziselwa ukukhanyisa okanye ukukhanyisa kwakhona.
I-inki yokumelana ne-solder esetyenziswa kwiibhodi ezininzi zesekethe iluhlaza, kwaye i-inki ye-solder yokuxhathisa esetyenziswa kwiibhodi ze-eriyali eziguquguqukayo ikakhulu zimnyama namhlophe.Ibhodi cable kunye nebhodi imodyuli camera ubukhulu becala sebenzisa yellow solder ukumelana inki, kunye nebhodi strip ukukhanya isebenzisa emhlophe okanye matte white solder ukumelana inki.
Ngokubanzi, umbala we-inki yokuxhathisa i-solder esetyenziswa kwi-PCB ikakhulu ixhomekeke kwiimfuno zabathengi bomzi-mveliso webhodi yesekethe.Shicilela ifilimu.Kwiibhodi zesekethe eziguquguqukayo, ii-inki ze-solder ezimhlophe azikwazi ukumelana nokugoba kuneminye imibala.
Kukho kwakhona ezinye ii-inki zokuxhathisa kwi-solder kwiibhodi zesekethe ezinemibala ekhethekileyo.Iinki ezininzi zokumelana ne-solder zalo mbala zikhethekileyo zenziwe ngabavelisi be-inki, kwaye ezinye zixutywe ngee-inki ezimbini zokumelana ne-solder ngomlinganiselo othile.Yidibanise (kwezinye iifektri ezinkulu zebhodi yesekethe, iinkosi zeoyile ngaphakathi zinokuyifaka imibala)
Kungakhathaliseki ukuba yintoni umbala we-PCB yokuxhathisa i-inki, kufuneka ibe nokuprintwa okulungileyo kunye nesisombululo, ukuze ihlangabezane neemfuno zoshicilelo lwesikrini somzi-mveliso kunye neemfuno zemveliso.
