Soldering Recommendations
- Flow Soldering (Radial Lead Type): Preheating 13020C (30-90 sec), Soldering Temp. 260C max (<1 sec).
- Reflow Soldering (Polymer SMD Type): Profile includes Preheating (150C to 180C within 90 sec), Peak Temperature (T1), and Time at Peak (t1). Specific temperature and time values depend on the reflow cycle.
- Reflow Soldering (Liquid SMD Type): Temperature at surface shall not exceed T.C. Duration over 200C and T.C. shall not exceed t and t seconds respectively. Preheat at 100C to 200C for max 180 seconds. Specific parameters vary by case size.
