PCB simbi stencilinogona kukamurwa mumhando dzinotevera maererano nemaitiro:

1. Solder paste stencil: Sezvinoratidzwa nezita racho, inoshandiswa kuisa solder paste. Cheka maburi muchidimbu chesimbi chinoenderana nemapedhi paPCB board. Wobva washandisa solder paste kudhinda paPCB board kuburikidza ne stencil. Paunenge uchidhinda solder paste, shandisa solder paste pamusoro pe stencil, uye isa bhodhi redunhu pazasi pe stencil. Zvadaro shandisa scraper kukwenya solder paste zvakaenzana pamusoro pemaburi estencil (solder paste inoyerera ichibuda mustencil kana yasvinwa) inoyerera ichidzika nemambure uye kuvhara bhodhi redunhu). Batanidza zvikamu zveSMD uye wozvifambisa pamwe chete, uye zvikamu zveplug-in zvinosungirirwa nemaoko.

2. Tsvuku tsvuku yepurasitiki stencil: Gomba rinovhurwa pakati pemapadhi maviri echikamu maererano nehukuru uye rudzi rwechikamu. Shandisa dispensing (kuparadzira kushandisa mweya wakatsikirirwa kunongedza guruu dzvuku pasubstrate kuburikidza nemusoro wakasarudzika) kuisa glue dzvuku pabhodhi rePCB kuburikidza nesimbi mesh. Wobva waisa zvinhu zvacho, uye mushure mekunge zvikamu zvanyatsonamirwa kuPCB, plug muzvikamu zveplug-in uye uende kuburikidza ne wave soldering.

. Dual process simbi mesh ine maviri simbi meshes, imwe yakajairwa laser simbi mesh uye imwe manera simbi mesh. Nzira yekuziva sei kana kushandisa manera stencil kune solder paste kana manera stencil yered glue? Kutanga nzwisisa kana kuisa solder paste kana red glue kutanga. Kana iyo solder paste ikaiswa pekutanga, ipapo solder paste stencil ichaitwa yakajairwa laser stencil, uye tsvuku glue stencil ichagadzirwa kuita manera stencil. Kana iwe ukatanga kuisa glue dzvuku, ipapo iyo tsvuku glue stencil ichaitwa yakajairwa laser stencil, uye solder pastencil ichagadzirwa kuita manera stencil.
