适用范围：This part of IEC 61188 provides the component and land pattern dimensions for small outlineintegrated circuits with “J“ leads on two sides (SOJ components) used in the reflow solderingprocess. Basic construction of the SOJ device is also covered. Clause 4 lists the tolerancesand target solder joint dimensions used to arrive at the land pattern dimensions.
