Hi Peter! What kind of straddle mount connector are you thinking about? If it's for a PCMCIA or PC card, there's a company that makes straddle mount connectors with solid solder deposits on each lead that you can slide on the boards without worrying about smearing solder paste, and then you reflow them along with the rest of the board. Teka's connectors with solid solder deposits work great, I've used them numerous times in the past.

What is the best process to assemble a straddle mount (edge mount) connector on the SMT line? Since the connector has to be installed manually prior to reflow, how can I avoid paste smearing between the connector leads and the SMT pad? The particular connector manufacturer in my case recommendeded a partial solder paste deposition on the pad and rely on solder wicking to complete a solder fillet. How reliable would such process be? 2. What are the defects and problems related to the straddle mount connector assembly? Any feedback is appreciated.
