Greg, Its an open ended question your asking here. What are you trying to do? Determine if your equipment is able to do what you need? E Determine your floor spacing? Determine what, if any, inspection equipment is needed? Determine constraints/line

Does anyone know of a source for a reasonably priced and simple airflow measuring instrument? A simple mechanical anemometer with a pitot tube would suffice (I think...) in this application since I'm just trying to verify proper operation of the refl

I am having problems with SMT electrolytic capacitors expanding and changing values after going through our reflow. The reflow profile we use includes temperatures of 200 deg C for 60 seconds and 230 deg C for 30 seconds. We need to use this profil

We reseantly considered purchasing the Meridian Series machine but we changed our mind. The reason for that was that Quad does not have to many installations of the Equipment, also the fact that hardly any of their field techs. have much training on

Does anyone have a quick reminder for a PCB with immersion gold surface finnish going through a reflow profile: Which of the following statements is more correct? A: In order to minimize gold in the intermetallics of the solder joint, the board temp

Many moons ago, at another company, we bolted an oval "carousel" to the ceiling. In our case, the carousel was use to convey wave soldering pallets from the end of a in-line washer to the from-end of the wave soldering machine. The pallets hung fro

We are considering retrofitting our Vectra wave soldering machine with a hot air knife. I've run our problem board on a machine with this option and it does seem to work; however, there is a concern of component failure due to thermal shock. Is thi

RF pcb is all gold with no typical land patterns and multiple surface mount components sharing the same pad. IPC-610-B doesn't speak to inspection criteria. The problems I'm seeing are, insufficient solder, skewed components. Some of the pads have
