A cikin tsarin samar da SMT, akwai hanyar rigakafin kuskuren gama gari wanda zai iya rage haɗarin ɓangarorin da ba daidai ba, rage yiwuwar kurakurai, da inganta ingantaccen ingancin duk samarwa. Ana kiran wannan hanyar da FII, wanda ke tsaye don binciken abu na farko.

bari mu ci gaba da gabatar da ayyukan wasu yadudduka a cikin PCB: 1. Solder Mask Layer 2. Layer allon siliki 3. Sauran Yadudduka

Sanannen abu ne cewa PCB wani yanki ne da ba makawa a cikin samfuran lantarki, wanda ya ƙunshi yadudduka da yawa, kowanne yana da takamaiman aikinsa. A yau za mu bincika ayyuka daban-daban na kowane Layer.

A ƙarshe bari mu koyi game da aikin 5 da 6 game da capacitor. Lokaci Tunatarwa

Ayyuka shida na Capacitor a cikin PCB (Sashe na 2) Kewaya Ajiye Makamashi

Capacitors wani abu ne na lantarki gama gari wanda ke taka muhimmiyar rawa a allon kewayawa. Capacitors suna aiki da ayyuka daban-daban a cikin allunan da'ira kamar tacewa, haɗa haɗin gwiwa, kewayawa, ajiyar makamashi, lokaci, da daidaitawa. Capacitors na iya tace hayaniya, watsa sigina, ware DC, adana makamashin lantarki, sarrafa lokaci, da daidaita mitoci don tabbatar da aiki da amincin kewayen.

Nau'o'in sifofi guda biyu na gaba da za a gabatar sune tsarin "N+N" da tsarin haɗin kai na kowane Layer.

Bari mu ci gaba da gabatar da tsari na gaba: tsarin “2-N-2”.

A yau, bari mu fara da mafi sauƙin ƙira, tsarin "1-N-1".

Dukanmu mun san cewa a cikin masana'antar kera kayan lantarki na zamani, fasahar HDI ta zama maɓalli mai mahimmanci wajen fitar da samfuran lantarki zuwa ƙaranci da haɓaka aiki. Tushen fasahar HDI ya ta'allaka ne a cikin ƙirar ta na musamman, wanda ba kawai yana haɓaka amfani da sararin samaniyar allon kewayawa ba amma yana ƙarfafa aikin lantarki da amincin sigina.

Na gaba, za mu ci gaba da nazarin ƙarfin lantarki na babban al'amari rabo HDI allon.
