Faylka Naxaasta Heerka STD
Taxanaha STD waa fasalka 1aad ee IPC foil naxaas ah oo loogu talagalay in loo isticmaalo sidii lakabka sare ee looxyada adag.Waxaa lagu heli karaa dhumucyo u dhexeeya ugu yaraan 12 µm ilaa ugu badnaan ED dhumucdiisuna waxay tahay 140 µm.Tani waa foil-ka kaliya ee ED ee naxaasta ah ee laga heli karo 105 µm iyo 140 µm dhumucdiisuna tahay, taasoo ka dhigaysa mid ku habboon looxyada loo qaabeeyey sida kuleylka kuleylka ama inay qabtaan qulqulo koronto oo waaweyn.
●Foornada lagu daweeyay ee cawl ama casaan
●Xoogga diirka sare
●Karti wanaagsan
●adhesions heer sare ah si ay u xoqin iska caabin
●Iska caabin daxalka heer sare ah
●Phenolic
●looxa Epoxy
●CEM-1, CEM-3
●FR-4, FR-3
●Tani waa badeecadeena caadiga ah ee ED foil foil oo leh taariikhda ugu dheer isticmaalka lakabka sare ee looxyada adag.
Tayada dusha sare
● 0 xabo gariirkiiba
● Fool si uu u yeesho midab isku mid ah, nadaafad iyo siman
● Ma jiro godad muuqda, godad biin ama daxal
● Ma jiraan cillado dusha sare ah sida xargo, baro ama xariiqyo
● Foilku waa inuu ahaadaa mid aan saliid lahayn oo aan lahayn meelo saliid ah oo muuqda
