HASL Plating Thickness

322

Winnie

Good Morning Everyone,

Could someone please tell me what the acceptable range is for HASL plating thickness. We have some raw boards with plating thicknesses ranging from 3-4 mils on a fine pitch QFP. We are expeiencing bridging at this location and am just trying to educate myself prior to conversations with the board house. Any help would be greatly appreciated.
