PCB zvigunwe zvegoridhekureva kumucheto metallization kurapwa chikamu paPCB bhodhi.
Kuti uvandudze mashandiro emagetsi uye kusagadzikana kwekuora kwechibatanidza, zvigunwe zvegoridhe zvinowanzo shandisa goridhe plating process.Izvi zvinotevera PCB yegoridhe chigunwe chegoridhe plating maitiro ekugadzira:
Kuchenesa: Kutanga, kumucheto kwePCB bhodhiinoda kucheneswa uye kubviswa kuti ive nechokwadi chekutsetseka uye kuchena kwepamusoro.
Kurapa kwepamusoro: Tevere, mupendero wePCB unofanirwa kubatwa pamusoro, kazhinji kuburikidza nekemikari yemhangura yekuisa, pickling uye mamwe maitiro ekubvisa tsvina uye oxide layer mukugadzirira kunotevera goridhe plating.
Goridhe plating: Mushure mekurapwa kwepamusoro, chigunwe chegoridhe chinoenda kuburikidza ne electroplating process.Nokuputira simbi mhinduro pamusorokumucheto kwePCB boarduye kushandisa ikozvino, simbi inoiswa pamusoro kuti iite yunifomu yesimbi inodzivirira layer.
Kucheneswa nekuongororwa: Mushure mekuputirwa negoridhe, zvigunwe zvegoridhe zvinoda kucheneswa kubvisa makemikari asara uye tsvina.Kuongororwa kwemhando yepamusoro kunozoitwa kuti ive nechokwadi chekuti mhando uye ukobvu hwemetalization layer yemunwe wegoridhe zvinosangana nezvinodiwa.Aya matanho ekuita anovimbisa kunaka kwegoridhe plating uye kuita kwakanaka kwemagetsi kwePCB zvigunwe zvegoridhe, ukuwo ichivandudza corrosion resistance uye kugadzikana kwekubatanidza.
