hello, are there any rules (of thumb or otherwise) for placing components when doing a hasl/selective tin plating. in our case, we have a board that is mostly hasl finish. then we have some buss bar pads that are selective white tin plated. is there a rule of thumb as to how close a component can be place to the pad that is selective white tin plated or is this entirely process/fabricator dependent? i'm assuming here that the fabricator must some how tape over the tinned pad to apply the hasl finish. thanks, =================================== From the desk of Tom Johnson Nuera Communications, Inc. 10445 Pacific Center Court San Diego, CA 92121 PH: (619) 625-2400
