1 New Product Technology Surf-Shooter SMT Surface Mount Connectors Zierick s surface mount terminals feature internal holes or slots at the base which foster a capillary solder wicking action for improved post reflow accuracy and joint strength. As the industry s first surface-mountable connectors to be supplied on a continuous reel, Surf-Shooter SMT connectors are used as part of Zierick s patented Surf- Shooter SMT (Surface Mount Technology) Assembly System to simplify surface mount assembly. The complete Surf-Shooter SMT system feeds, separates, and presents the continuous-format, surface-mountable connectors to the vacuum pick-up head of a new or existing placement system. The continuous-format design of the stamped Surf-Shooter SMT connectors eliminates the need for the prepackaging that surface mount connectors typically come in. Even odd-form components can be fed to the placement system on continuous reels, eliminating hand assembly. For easy integration into customer assembly lines, the Surf-Shooter SMT Assembly System operates with virtually any standard placement system. Each Surf-Shooter SMT system consists of a feeder system and continuous Zierick connectors. Zierick supplies or modifies feeders for virtually any SMT placement system. Benefits: The first surface-mountable connectors to be supplied on a continuous reel, for easy feeding to the vacuum pick-up head of a placement system Used within Zierick s Surf-Shooter SMT Assembly System to feed, separate, and present the continuous format connectors to the pick-up head Eliminates plastic prepackaging due to the continuous format design Surf-Shooter SMT Assembly System operates with virtually any standard flexible placement system Available in 16mm and 24mm tape format Continuous Surf-Shooter SMT connectors are separated and presented to the vacuum pick-up head. Connectors are supplied on continuous reels, eliminating expensive and wasteful plastic prepackaging. Eliminates hand assembly of odd-form components.

3 Surf-Shooter SMT Surface Mountable Pins Surf-Shooter SMT pins and posts are specially designed for high-reliability PCB interconnection applications. They are available in 0.025" square (0.64mm) and diameters of 0.040" (1.02mm), 0.043" (1.09mm), 0.060" (1.52mm), and 0.080" (2.03mm). To increase interconnection reliability, they utilize capillary action of reflowing solder to improve solder joint strength. Pull-force tests reveal that a post with proper capillary action has a much higher retention to the printed circuit board than a post without the capillary action feature. The higher retention force is attributable to two conditions: 1) The very thin layer of solder between the base of the pin and the solder pad. Solder is a weak alloy with a low yield stress. A thicker layer of solder will fail before a thinner layer will. Solder behavior is analogous to that of adhesive: a thinner layer of adhesive bonds more strongly than a thicker layer. 2) As the solder paste reflows, flux and other active ingredients in the solder cause outgassing. These gases get trapped under a relatively large surface like the base of the pin. The trapped gases create voids in the solder that are clearly visible when the pin is pulled off or the solder joint is cross-sectioned. Pins that employ capillary action have fewer and smaller voids because the capillary tube provides a way for gases to escape. Cracks in solder joints develop from such voids during thermal cycling. Field evaluations show that posts with enhanced capillary action are more resistant to the effects of thermal cycling.
