Menene launi na allon PCB, kamar yadda sunan ya nuna, lokacin da aka sami allon PCB, mafi mahimmanci za ku iya ganin launin mai a kan allo, wanda shine abin da muke kira da launi na PCB. Launuka gama gari sun haɗa da kore, shuɗi, ja da baki, da sauransu. Jira.
1. Koren tawada ita ce aka fi amfani da ita, kuma ita ce mafi tsawo a tarihi, kuma mafi arha a kasuwa a halin yanzu, don haka yawancin masana'antun ke amfani da kore a matsayin babban launi na kayayyakinsu.
2. A karkashin al'ada yanayi, dukan PCB hukumar samfurin ya tafi ta hanyar hukumar yin da kuma SMT tafiyar matakai a lokacin samar tsari. Lokacin yin allon, akwai matakai da yawa waɗanda dole ne su shiga cikin dakin rawaya, saboda kore yana cikin rawaya Sakamakon dakin haske ya fi sauran launuka, amma wannan ba shine babban dalili ba.
Lokacin sayar da abubuwan haɗin gwiwa a cikin SMT, PCB dole ne ya bi matakai irin su manna solder da faci da tabbatarwar AOI ta ƙarshe. Waɗannan matakan suna buƙatar daidaitawar gani da daidaitawa. Koren bangon launi ya fi kyau don gano kayan aiki.
3. Common PCB launuka ne ja, rawaya, kore, blue da baki. Duk da haka, saboda matsaloli irin su tsarin samarwa, tsarin binciken ingancin layukan da yawa har yanzu dole ne ya dogara da ido tsirara da sanin ma'aikata (ba shakka, yawancin fasahar gwajin jirgin sama a halin yanzu ana amfani da su). Ido suna kallon allon kullun a ƙarƙashin haske mai ƙarfi. Wannan tsari ne mai matukar gajiyarwa. Idan aka kwatanta, kore shine mafi ƙarancin cutarwa ga idanu, don haka yawancin masana'antun a kasuwa a halin yanzu suna amfani da koren PCBs.
4. Ka'idar blue da baki ita ce, bi-da-bi an yi su da abubuwa kamar su cobalt da carbon, waɗanda ke da wasu ƙayyadaddun wutar lantarki, kuma ana iya samun matsalolin gajeriyar kewayawa lokacin da wutar lantarki ke kunne. Haka kuma, koren PCBs suna da kusancin muhalli, kuma a cikin yanayin zafi mai girma Idan aka yi amfani da su a matsakaici, gabaɗaya ba za a saki iskar gas mai guba ba.
Hakanan akwai ƙananan masana'antun a kasuwa waɗanda ke amfani da allon PCB na baƙi. Manyan dalilan da suka sa haka su ne dalilai guda biyu:
Ga alama mafi girma-karshen;

A halin yanzu, galibin allunan Android ɗin baƙaƙen PCB ne.
5.
