21. What is the recommended way to connect the sensor? Answer (Pellistors) For VQ500 series sensors please use sockets http://www.cambion.co.uk/Catalogue/Parts/1813.htm. For other pellistors connect to header legs by soldering or mechanical methods

Is a bridge considered a defect, if adjacent pads/component leads are electrically connected (common) via a trace but said trace is covered in solder mask ? Essentially, of course bridges are never a target but is rework required/de-bridging require

Dr. Lee: In using environmental screening tests to assess solder joint reliability, what are the effects that make low temperature vibration effective in screening of poorly wetted solder connections? What temperature and vibration profile are effe

is there an adapter or cable to run from SMP1 to SMEMA connection. What do each mean and are they in someway interchangable? I have a conveyor w/ SMP1 that is to be connected to a machine w/ SMEMA.... any thoughts? thank you greg

Should I use thermals or direct connects on vias from BGA pads to power planes. The via is connected to the BGA pad via a short 8mil trace.

A firm grasp on the sublime. Mike points-out a good reason to describe Claude's problem as "open connections" or "open solder connections"? [Ahhh geez, wut a spoil spurt]

Tough to say based on what you have told us. Things to Determine are: * Is the heat at the solder connections that are not reflowing properly adequate? * Is the pad surface of the solder connections that are not reflowing properly solderable?

Yannick, If we leave the 201 issue aside; have you checked where those BGA pads are connected to? Could those be power/ground balls connected to large (difficult to heat up) planes by any chance? Erhan

There is nothing inherently wrong with voids in solder connections. They: * Do indicate that the reflow soldering process is not well controlled. * Can comprise the strength of the solder connection. Look here: http://www.smtinfocus.com/smt_failure
