Try Heller Industrie's website at http://www.hellerindustries.com They have a formula that they offer for free that calculates land pad geometry to component weight to prevent drop off of components during second reflow. If you can't find it, give t

Hi Steve, 20 mil pitch shouldn�t be that problem nowadays. In your case bridging and poor wetting seem to go hand in hand. For the poor wetting try to eliminate it by using different paste (higher activated) and work on your profile. Coplanarity also
