In a cost-reduction effort, our Design group is attempting to eliminate silk-screen (legend ink) on some new products. By the elimination of this process, there will be a slight decrease in the cost of the bare board. Presently, the silk screen den

If you having bad rotations as main issue this should be fixed at SMT programming side before needing inspection. There are software tools that can eliminate this issue and first article inspection related to rotation errors can be eliminated. ie sti

I am interested in getting some feedback on what different companies are doing to eliminate the solder beading issues on 0603, 0402 chip components using a no-clean process. We are currently incorporating a solder mask removal between the solder lan

Hi, We had tomb-stoning on a product, and it was quite severe. We eliminated it by reducing the amount of solder paste on the small passible component pads. We used a 5 thou stencil, with 20% reduction, and it eliminated the problem. Regards, Gra
