Did you have a recess for the pin to sit in or is it one with the full PTH?

Hello, I was wondering if solder paste is taken out of refrigeration and left to sit at room temperature sealed. How long will it usually last at room temperature on average before going bad? If solder paste goes bad from sitting at room temperatu

We have been struggling for a while with some through hole sealed mechanical relays that fail at test after they have been sitting a while. They will initially pass test, but seem to fail if they sit for a few days. We made sure our wave process was

As you already know, it depends on the paste. There isn't really a rule of thumb, but less time exposed it better. The issue is the flux exposure to the air and ambient conditions. The flux can evaporate or absorb moisture from the air. If the paste

Trying to show documentation/expert opinion to an operator or 2 why it's important to not let a first piece, that they so diligently built for the next shift to let sit for an hour, why that's not a good idea...other than me telling them so. And tel

Sorry i didnt explain it vey well,the parts that are misaligned are always sitting next to these particular tanatlum capacitors.It affects 0805 parts and A tsop36 and can even cause a short on a bga right in the corner where the tant sits.If you chan

our company has just purchased the MC110 High-Accuracy Manual Stencil Printer. the only thing I'm not sure about is how to use the PCB Edge Stopper. how is this used? the groove with the stoppers on it is too deep to hold a board because it would s

Do the parts sit directly on the PCB? Typical 2.0 mm Max is desired for the component to be off the PCB. Are stand-offs an option? The long lead wiggles as it passes through the wave and thus agitating the air out.Does your wave a "dancer" option?

We build a product that requires a lithium battery. There is a Smt Battery clip soldered onto two gold pads on a FR4 PCB. The battery is forced by two little clips punched out to provided downward pressure in the battery holder, enabling the lithium
