Zvinoenderana nemaitiro, iyo pcb stencil inogona kukamurwa muzvikamu zvinotevera:

1. Solder paste stencil: Sezvinoratidzwa nezita racho, inoshandiswa kukwesha solder paste.Chengeta maburi muchidimbu chesimbi chinoenderana nemapedhi ebhodhi rePCB.Wobva washandisa solder paste kupedhi kuPCB board kuburikidza ne stencil.Paunenge uchidhinda solder paste, shandisa solder paste pamusoro pe stencil, uku bhodhi redunhu richiiswa pasi pe stencil, wobva washandisa scraper kukwenya solder paste zvakaenzana pamaburi e stencil (iyo solder paste inosvinwa kubva simbi mesh. inoyerera ichidzika nemambure uye inovhara bhodhi redunhu).Namira zvikamu zveSMD, uye reflow soldering inogona kuitwa zvakafanana, uye zvikamu zveplug-in zvinotengeswa nemaoko.

2. Tsvuku yepurasitiki stencil: Kuvhura kunovhurwa pakati pemapadhi maviri echikamu zvichienderana nehukuru uye rudzi rwechikamu.Shandisa dispensing (kuparadzira kushandisa mweya wakadzvanyirirwa kunongedza glue dzvuku kune substrate kuburikidza nemusoro wakasarudzika) kunongedza tsvuku tsvuku kubhodhi rePCB kuburikidza nesimbi mesh.Wobva wamaka izvo zvikamu, uye mushure mekunge zvikamu zvanyatsonamirwa kuPCB, plug muzvikamu zveplug-in uye pfuura wave soldering pamwe chete.

3. Dual-process stencil: Kana PCB inoda kukweshwa ne solder paste uye dzvuku guruu, ipapo dual-process stencil inoda kushandiswa.Iyo mbiri-yekuita stencil inoumbwa nematenesi maviri, imwe yakajairwa laser stencil uye imwe yakatsika stencil.Nzira yekuziva sei kana kushandisa stencil kana tsvuku glue kune solder paste?Kutanga nzwisisa kana kukwesha solder paste kana red glue kutanga.Kana iyo solder paste yaiswa pekutanga, ipapo solder paste stencil inogadzirwa mune yakajairika laser stencil, uye tsvuku glue stencil inogadzirwa kuita stencil yakatsikwa.Kana iyo glue dzvuku ikaiswa pekutanga, ipapo tsvuku glue stencil inogadzirwa mune yakajairika laser stencil, uye solder pastencil inogadzirwa kuita stencil yakatsikwa.
