3 OU MINI-CR xperience with SMT Connectors ecause of the importance of SMT technology we present a brief review of the concept: 1 Concept study SMT-Connector with Guide pins Surprisingly, an exception is still in many cases the placement of electro-mechanical components, such as connectors. Some of these components are still placed by hand, primarily due to their larger dimensions or higher mechanical placement forces required. Soldering is done with conventional wave solder machines. This duality of technology, SMT and wave solder, is undesirable in a production environment. Therefore, SMT connectors are becoming more and more desirable, even in small and medium size production runs. The following is a summary of our experience with SMT connectors, based on years of sales and Millions of installed connectors. Requirement on SMT Connectors High-temperature performance (-250 C) utomatic placement Solder-in components are placed on the printed circuit board (PC) with their pins pushed through holes in the PC. The pins are then soldered from below using a wave solder machine. (see Fig. 2) y contrast, SMT components are placed onto the PC but use solder paste which is applied to the surface of the PC (see Fig. 2). Resistant to mechanical forces (horizontal and vertical) Contact coplanarity of less than 0.1 mm utomatic Testing Requirements for the Pin-Socket combination Low insertion and withdrawal forces Low and constant resistance 2 PC Conductors PC Solder-In Technique Component Solder Pins Solder Wave ca. 230 C Surface-Mount Technique (SMT) Component Infra-Red Radiation to 235 C Solder Good high frequency properties Safe locking of the two connector halves oard-to-board SMT connectors are shown in Fig. 3. s shown, they have two guide pins and a vacuum adapter plate. The guide pins facilitate easy placement by pre-aligning the connector with the solder pad and taking up some of the mechanical forces due to relative movement between circuit boards. Solder Paste Solder Legs Solder Conductors PC Surface-Mount (SMT) Guide Pins (OU) Component Infra-Red Radiation to 235 C Solder Paste Solder Legs Solder Conductors PC Guide Pins (OU) ctive and passive SMT components are placed automatically with robotic placement equipment onto the PC.

4 OU MINI-CR xperience Guide Pins Without exception, the guide pins have proven to be successful. iameter and length is 1.00 mm. They provide excellent compensation for the horizontal forces. The alignment feature during component placement has become less important since today's automatic placement machines operate with great accuracy. However, for smaller production runs, where hand-placement is used, the pins have shown to be of significant help when aligning the connector with the PC solder pad. 4 Vacuum dapter Plate Coplanarity max. 0.1 mm Grid The 1.2 x 2.54 mm grid in the contact area meets most requirements. Contacts Contacts are made of e-cu. They have two wiping contact points with long wiping action. The resulting low insertion and withdrawal force is less than 0.18 N. Contact resistance 3is less than 6 mω and results in exceptional good contact performance. For applications with very high number of contact positions the low contact forces provide significant advantage during assembling or disassembling circuit boards. Contact impedance is considered in all cases exceptional. Contact esign The design of gull-wing solder legs involved a significant engineering effort. However, it appears that the spring action of the gull wings is of less importance than originally thought. xperience has shown that simple square posts (.64 x.64 mm), formed into a right-angle, can also be mounted onto a surface-mount board. C Typical Values 5 Guide Pins 200 Customer Customer Customer 2 max. 0.1 mm Time (sec) Coplanarity It ist absolutely essential that a value <0.1 is maintained. uring the fully automatic assembly OU has a 100% optical inspection to make sure that this value is maintained. Vacuum dapter The vacuum adapter plate is a complete success. Fully automated placement of the connectors is not only possible with a grabber (mostly larger and bulky) but also with the smaller vacuum head. imensions Minimum component height of 8.5 mm for board-toboard appears to be sufficient for most applications. Most requirements are in the 10 to 18 mm range. Contacts are designed to take up to 1.5 mm tolerance in component height. xample: For a nominal height of 10 mm the board-toboard distance can be extended to 11.5 mm. Insulation ody The high-temperature performance of the insulation body is of great importance. Temperature requirements are defined by a Temperature vs. Time diagram (see Fig. 5) Contact surface finish in the solder area is CuNiSn (3 µm). The tin alloy is 90% Sn and 10% lead. It has been shown acceptable for most solder pastes. Quality ssurance Quality assurance at OU follows ISO 9001 guidelines. Testing is performed with statistical methods in accordance with QL 0.4. The most important aspect is the coplanarity which is tested with a profile projector. Seite 4 OU-Steckverbindungssysteme GmbH & Co.
