The company has introduced surface-mountable PCB headers that improve solder joint strength in a wide range of PCB applications through enhanced capillary action of reflowing solder. The capillary motion of the solder paste during reflow draws the header down tightly to the PCB, creating a thinner, stronger solder-joint. The SMT header provides a way for solder to escape, which results in fewer and smaller voids. The connection formed in this way exhibits 50% higher retention force than that of conventional designs. Additionally, the capillary action draws the header into proper position on the solder pad, even if the connector has been placed off center. Co-planarity is also assured. Lastly, the SMT header provides resistance to thermal shock and thermal cycling because the component base is made of the same material as the PCB.
Headers are available in a variety of pin lengths and sizes.
