Mene ne launi na hukumar PCB, kamar yadda sunan ya nuna, lokacin da ka sami allon PCB, wanda ya fi dacewa zaka iya ganin launi mai mai, wanda shine abin da muke magana dashi azaman launi na hukumar PCB. Launuka gama gari sun hada da kore, shuɗi, ja da baki, da sauransu jira.

1. Green tawada da aka fi amfani da shi sosai, mafi dadewa a cikin tarihi, kuma mafi arha a cikin kasuwar masana'antu, ana amfani da mafi yawan adadin samfuran samfuran su na yanzu.

2. A karkashin yanayi na yau da kullun, duk kayan aikin PCB ɗin dole ne ya bi ta hanyar sanya hannu da SMT tafiyar matakai yayin aiwatar da samarwa. Lokacin yin allo, akwai hanyoyin da yawa waɗanda dole ne su shiga cikin rawaya, saboda kore yana cikin rawaya mai haske ya fi wasu launuka mafi kyau, amma wannan ba babban dalili bane.

A lokacin da aka shirya sayar da kayan sarrafawa a SMT, PCB dole ne ya shiga cikin hanyoyin kamar mai dillali da kuma faci da tabbacin AOI na ƙarshe. Wadannan hanyoyin suna buƙatar daidaitawa da daidaitawa. Launin Fage Green ya fi kyau don gano kayan aikin.

3. Abubuwan PCB na yau da kullun sune ja, rawaya, kore, shuɗi da baki. Koyaya, saboda matsaloli kamar tsarin samarwa, tsarin binciken da yawa har yanzu dole ne a yi amfani da fasahar gwaji (ba a halin yanzu, yawancin fasahar gwaji masu fashewa). Idanun suna tsaye koyaushe suna tsaye a jirgin ƙarƙashin haske mai ƙarfi. Wannan tsari ne mai wahala sosai. In mun gwada da magana, kore shine mafi ƙarancin cutarwa ga idanu, don haka yawancin masana'antun a kasuwa suna amfani da kore kwastom.

4 Haka kuma, kore kwastoman ne m tsabtace, kuma a cikin yanayin zazzabi lokacin da aka yi amfani da su a matsakaici, gabaɗaya babu gas mai guba.

Hakanan akwai karamin adadin masana'antun a kasuwa wanda ke amfani da allon PCB na Black PCB. Manyan dalilai na wannan dalilai biyu ne:

Ya kasance mafi tsayi;
Bloard Bloard ba abu mai sauƙi ba ne a ga wanda ya gaza, wanda ya kawo wani matsala na wahala ga kwafin kwafi;

A halin yanzu, yawancin mafi yawan Android sun saka kwamitocin sune kwamfutar fata.

5. Tun daga tsakiyar matakai na ƙarni na ƙarshe, masana'antar ta fara kula da launi na PCB, don haka mutane sannu saboda launuka masu yawa suna da kore, dole ne launi.
