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, bari mu bincika yadda ake gwada stencil na SMT. Ingancin dubawar samfuran stencil na SMT an raba shi zuwa matakai huɗu masu zuwa

A yau za mu ci gaba da koyo game da karshe hanya na kera PCB SMT stencil: Hybrid tsari.

Yau za mu ci gaba da koyo game da na uku hanya na kera PCB SMT stencil: Electroforming.

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.

Yau, za mu tattauna yadda za a zabi kauri da kuma zayyana apertures lokacin amfani da SMT stencil.

A yau za mu koyi game da wasu na musamman SMT PCB aka gyara da kuma Bukatun ga siffar da girman da apertures a kan manne bugu stencil.

Bari mu ci gaba da koyo game da buƙatun ƙira don ƙirƙirar ƙirar SMT. Babban masana'anta na iya karɓar nau'ikan nau'ikan takaddun takaddun abubuwa guda uku don yin stencil Bugu da ƙari, kayan da muke buƙata daga abokan ciniki don yin samfuri gabaɗaya sun haɗa da yadudduka masu zuwa Tsarin budewa na stencil yakamata yayi la'akari da rushewar manna mai siyar, wanda galibi an ƙaddara ta abubuwa uku masu zuwa.

Yanzu bari mu koyi game da buƙatun ƙira don ƙirƙirar stencil na SMT. 1. Babban Ka'ida 2. Stencil (SMT samfuri) tukwici ƙira 3. Takardun shirye-shiryen kafin SMT stencil samfurin zane

Ƙayyadaddun tsari na ƙirar SMT stencil ya haɗa da abubuwa masu mahimmanci da matakai don tabbatar da inganci da daidaito na stencil. Yanzu bari mu koyi game da mahimman abubuwan da ke cikin samar da stencil na SMT: 1. Frame 2. Tsaki 3. Stencil Sheet 4. M 5. Tsarin Tsarin Stencil 6. Tsarin Stencil 7. Tashin hankali 8. Alamar maki 9. Zaɓin kauri na Stencil

A yau, za mu koyi game da manyan kayan da aka sanya su cikin SMT Stencil. SMT stencil da farko ya ƙunshi sassa huɗu: firam, raga, foil stencil, da m (viscose). Mu yi nazarin aikin kowane bangare daya bayan daya.
