I've got a small smt board I've already got working prototypes of, which uses a tactile switch. I've got another much less expensive tact switch of similar size that I had avoided due to a difference in actuators I originally had no way around. Now I

When reflowing a Vishay PowerPak SO-8 & using the recommended footprint from the data sheet, the component is skewing in reflow, to solve this we have to add a glue dot to both sides of the part, will making the PCB land pad 1:1 with the Solderable

Hello, I am looking into the use of a Samtec SEAM-50-02.0-L-10-2-A-GP-K-TR on a board. Is anyone around who has experience with this component? Specifically, we are looking for design advice for stenciling and soldering. The component is a sold

I am in urgent need of a pcb land patten (footprint)for this device. I have the component data sheet with with package dimensions from Motorola, but they do not include the recommended land pattern. I requested a patten over a week ago, but have no

Everybody's right! Two concerns are proper preheat for the flux and reduced thermal shock to surface mount components. The stupid er dumb thing is that these can be at odds with each other. The flux vendor usually specs topside temp before wave.

| We've noticed that there are many different recommendations for pad sizes for various SMT parts. This seems to vary wildly from manufacturer to manufacturer for the same case sizes. Is there any standards that can used used to specify these sizes

Hi, I can give my opinion in this topic since I worked with both machines. To say the truth, I would recommend neither machine. First of all, operating software is much quite the same for both machines. The TP9 is true that has a larger footprint ov

Thanks Bob. I just didn't have enough experience with production SMT (vs hand-soldered prototypes) to know how finicky some things like this are. I've tried to do a lot of reading, but I haven't seen much that talks about things like this. I also hav

| Hello: | I would like to know what causes tombstombing and how can it be prevented? | Thx. | Nichol Hi Nichol! A tombstone happens when solder doesn't wet equally on both terminations during reflow...now why that happens can be found by looking at
