John, SOT 23's on the bottom side is no real problem...as long as you get the orientaion to the wave right and you remember to increase the pad sizees to allow the solder to get to the pads. Soldering with only one wave would be trick as Vinesh sugg

Thanks guys, since I have no control as to who makes the board (probably the lowest bidder), I guess I'll keep the SOT's on top. Thanks for your help, John | John, | | SOT 23's on the bottom side is no real problem...as long as you get the orientai

| Hopefully, everybody suffers from solderability of SOT-23 devices and I would like to know how everybody else resolves this problem. | Historically, here, we have always gone for 6 thou stencils. I found that going to an 8 thou stencil improved the

Based on your knowledge and experience, could you tell me about speed differences when placing a mix of SMD at mass production? We could consider packages like the small R & C chips, then SOD323, SOT-23, SOT-23-5, SOT23-6, SON6, QFN8, SOIC-8, SOIC-16

Solder skips on SOT23 parts is the most common issue when soldering surface mount designs. The two most common causes are the wave height too low or there is too much gassing of the flux as it contacts and seperates the wave. Stck some parts on your

We are experiencing 2%+ dropout on one particular SOT23 device. This seems to occur during the actual pickup phase. I have made sure that my pickup position and height are correct. If I single step through the forward feed of the component, viewing i

| Dear all, | | Has anyone come across an electronic source for SOT23 etc; part markings and their meanings. Obviously, I could wade through the various data books.........but I don't really want to.....yet. | | Thanks in advance, | | Chris. | Tr

We use an EKRA E4 printer, but the concept sounds the same as far as the fiducial alignment goes. I have found that SOT-23 components work the best for fiducials - and I always make it a point to use them on our older PCB's (where the screens do not

I am having a problem with SOT23 moving off their pads during reflow. We did not have this problem yesterday. On the pads and surrounding area looks like a lot of flux spatter. I looked through the threads but they didnt help me much. I know what 3
