General recommendation on stencil opening design a. Stencil opening dimensions: L (Length), W (Width), T (Thickness). General design rule a. Stencil thickness (T) = 75 ~ 125 μm 𝑊 b. Aspect ratio = ≥ 1.5 𝑇 c. 3. Aspect area = 𝐿×𝑊 2𝑇(𝐿+𝑊) ≥ 0.66 Reference design a. Stencil opening thickness: 100 μm b. Stencil opening for leads: Opening to footprint ratio is 90%.

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. PCB design preference 1. 2. 3.5 Use 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 PCB movement. Solder paste with fine particles: powder particle size is 20-45 μm. 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 Figure 17: ST ECOPACK® recommended soldering reflow profile for PCB mounting Minimize air convection currents in the reflow oven to avoid component movement.
