I have a small board with some chips and 2 connectors (1 large and 1 small) with gull wing leads. The large connector has some "disturbed" solder joints per my QA people. These joints are toward the ends of the connector, not toward the middle. Th

We made huge leap from a Zevatech to a My9 three years ago and have been very happy. The MY9 beat out Siemans and Philips for the honor. I am always looking for used MY9 and would buy one without hesitation having gotten over the learning curve. We
