Our AOI machines have actually caught wrong resistors before. A reel gets swapped, a vendor sends a wrong part, things happen. To think that we can't rely on resistor markings anymore, that just sucks.

While I wouldn't be happy with this "Hershey's Kiss" appearing solder connection, I'd suck it up and and accept it as acceptable according to IPC-A-610F, Section 5.1

Suck it and see, start at a 3V pulse, then a 5V pulse, then a 12V pulse, time is not likely to be that critical but a few milliseconds should do! sarason

We were using a heller 1500 and an electrovert minipak wave solder. I don't recall the duct width or CFM. 6"-8" maybe? Probably want to over size it a bit as its easy to turn the fan down if you start sucking out the AC.

Stress concerns, spread over 50 pins. Madness, but then people do still seem to have a level of paranoia with SMT. Here we'd suck it up and handsolder them, and the operatives would not be happy about it.

Hi, just wondering are many assemblers using vacuum reflow systems, whether they be forced air based or vapour phase type ? If so, anyone seeing any negatives caused by the vacuum with regards liquid solder being 'sucked' away from the joints in the

Overprint, that is putting extra solder on with the stencil that is even further out from the pads, with the idea that it will suck that solder up during reflow? I could give that a try. Are there any general recommendations when overprinting? And wh

what is the size of that diode? We had some issues where part was sucked out of tape before nozzle actually touched it and flipped in the air.

Thank you all for your replies. Thanks to your replies and backup from the IPC-SM-782A (section 3.6.3.2) and James Blankenhorn's "SMT Design Rules & Standards," the designer has agreed to provide adequate clearance between the via and the pad. I wi

Added to MARK suggestion, you should verify you xy table height also by using the meter listed in the maintenace manual. If everything is fine, then i suggest you should check the placement air kisses( can suck your component back up or release to q
