			 Surface Technics 
			 | 
			
			 1.IMG:smooth surface, good adhesion, no oxidation under long using 
			2.gold plating(thick gold:1-50U"):good wear-resistance 
			3.HASL:better price, not easy oxidation, easy to welding, smooth surface 
			4.HAL: better price, not easy oxidation, easy to welding 
			 | 
			
			 1.IMG:high price 
			2.Gold plating(thick gold):high price 
			3.HAL:surface is not flat, not suitable for BAG packaging
