Go to Zephertronics web site, they have a neet rework system that was demo'd at PCB Design West. Ted Nathan PCB Designer Three Five Systems >>> [log in to unmask] 04/25/00 11:11AM >>> Dear Technetters, How do you handle rework of BGAs when there are BGAs on both sides of the board and they are nearly directly on top of one another? Similarly, how do you rework BGAs when the bottom side of the board is loaded with passives and ICs inside of the area outlined by the vias of the topside BGA? Our typical boards are 12 to 14 layers and are 0.062" thick. Thanks in advance for your advice.
