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
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.
Kamar yadda muka sani cewa, Tare da haɓakar haɓakar haɓakar sadarwa da samfuran lantarki, ƙirar allon da'irar da aka buga azaman abubuwan jigilar jigilar kayayyaki shima yana motsawa zuwa matakan girma da yawa. Manyan jirage masu yawa na baya ko uwayen uwa tare da ƙarin yadudduka, kauri mai kauri, ƙananan ramuka, da wayoyi masu yawa za su sami ƙarin buƙatu a cikin mahallin ci gaba da haɓaka fasahar bayanai, wanda ba makawa zai kawo babban ƙalubale ga hanyoyin sarrafawa masu alaƙa da PCB. .
PCB ta wayar hannu ɗaya ce daga cikin mahimman abubuwan da ke cikin wayar hannu, alhakin iko da watsa sigina gami da haɗi da sadarwa tsakanin nau'ikan nau'ikan daban-daban.
A yau za mu ci gaba da koyo game da hanyar na biyu na kera PCB SMT stencil: Laser Cutting. Yanke Laser a halin yanzu shine mafi shaharar hanya don kera stencil na SMT. A cikin SMT karba-da-wuri sarrafa masana'antu, fiye da 95% na masana'antun, ciki har da mu, amfani da Laser yankan ga stencil samar.
A yau, za mu ci gaba da bincika hanyoyin uku na kera PCB SMT stencil: Chemical Etching (Chemical Etching Stencil), Laser Cutting (Laser Cutting Stencil), da Electroforming (Electroformed Stencil). Bari mu fara samar da sinadaran etching.
