Product marking may be rotated by 90° for assembly plant differentiation. In no case should this product marking be used to orient the component for its placement on a PCB. Only pin 1 mark is to be used for this purpose. **DS4994** - **Rev 3** **page 7/13** **EMIF08-1005M16 Recommendation on PCB assembly** ## **3 Recommendation on PCB assembly** ## **3.1 Stencil opening design** 1. General recommendation on stencil opening design - a. Stencil opening dimensions: L (Length), W (Width), T (Thickness). 2. General design rule - a. Stencil thickness (T) = 75 ~ 125 μm - W - b. Aspect ratio = T[≥1.5] - L × W - c. Aspect area = 2T L + W ≥0.66 3. Reference design - a. Stencil opening thickness: 100 μm - b. Stencil opening for leads: Opening to footprint ratio is 90%. ## **Figure 12.

## **3.2** ## **Solder paste** 1. Halide-free flux qualification ROL0 according to ANSI/J-STD-004. 2. “No clean” solder paste is recommended. 3. Offers a high tack force to resist component movement during high speed. 4. Solder paste with fine particles: powder particle size is 20-45 μm. ## **3.3 Placement** 1. Manual positioning is not recommended. 2. It is recommended to use the lead recognition capabilities of the placement system, not the outline centering 3. Standard tolerance of ±0.05 mm is recommended. 4. 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. 5. To improve the package placement accuracy, a bottom side optical control should be performed with a high resolution tool. 6. 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. ## **3.4** ## **PCB design preference** 1. To control the solder paste amount, the closed via is recommended instead of open vias. 2. 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. **DS4994** - **Rev 3** **page 9/13** **EMIF08-1005M16 Reflow profile** ## **3.5 Reflow profile** ## **Figure 14.
