General recommendation on stencil opening design a. Stencil opening dimensions: L (Length), W (Width), T (Thickness). Figure 12. Stencil opening recommendation L T b. General design rule ◦ Stencil thickness (T) = 75 ~ 125 μm ◦ ◦ 1. W W ≥ 1.5 T L  ×  W ≥ 0.66 2T L  + W Reference design a. Stencil opening thickness: 100 µm b. Stencil opening for leads: Opening to footprint ratio is 90% Figure 13.

DS6650 - Rev 4 0.05 mm Halide-free flux qualification ROL0 according to ANSI/J-STD-004. “No clean” solder paste is recommended. Offers a high tack force to resist component movement during high speed. Use solder paste with fine particles: powder particle size 20-45 µm. page 8/12 ESDAXLC6-1MY2 Placement 3.3 Placement 1. 2. 3. 4. 5. 6. 3.4 PCB design preference 1. 2. 3.5 Manual positioning is not recommended. It is recommended to use the lead recognition capabilities of the placement system, not the outline centering Standard tolerance of ±0.05 mm is recommended. 3.5 N placement force is recommended. Too much placement force can lead to squeezed out solder paste and cause solder joints to short. Too low placement force can lead to insufficient contact between package and solder paste that could cause open solder joints or badly centered packages. To improve the package placement accuracy, a bottom side optical control should be performed with a high resolution tool. For assembly, a perfect supporting of the PCB (all the more on flexible PCB) is recommended during solder paste printing, pick and place and reflow soldering by using optimized tools. To control the solder paste amount, the closed via is recommended instead of open vias. The position of tracks and open vias in the solder area should be well balanced. A symmetrical layout is recommended, to avoid any tilt phenomena caused by asymmetrical solder paste due to solder flow away. Reflow profile Figure 14.
