Hi Steve, my company is using a supplier called NAS or NASTEKA, located in USA. I just don't have the adress with me because of answering from home. If the company name is not sufficient, please contact me offline. They are selling gullwings with different pitches, standoffs, with or without included solder in the clamp, different fluxtypes and so on. Pins are solder coated and come from a reel. You have to cut off the number of pins required and put them onto the lands on the pcb where they get stuck due to mechanical clamping. Soldering can be done by reflow or with a hot bar. We use the hot bar and soldering is quite straight forward. A big issue with making a pcb a smd-part is coplanarity of the pins. One point is bowing of the pcb. Another is handling: gullwings are sensitive to handling due to the feet of them which easy can be bend by touching with your hand. If you preferably use some kind of machine for cutting and pushing the pins on to the pcb, be sure to do some testing on this machine regarding wether this machine is able to transport the pins from their reel to the cutting knife without bending the feet of the pins and being able to push them on to the pcb in a centered way. Also outer dimensions of the pcb are critical if you plan to hold the pcb during pushing the pins on to it by its outer sides. The edge form of the pcb is important. Prefer milling, not scribing. Also be sure that the pins are always perpendicular to the surface. Little angles with higher standoffs will give you significant deviations of the "deepest points" of the feet of the pins. By the way, why do you want to use gullwings? For coplanarity, j-leads are more suitable. Reliability, as recently read in this forum, is equal. Inspectability of solder joints should be no issue regarding the usually high standoffs of the pins (about 3 mm or greater). Hopefully this helped a little. U.
