Gary, Paladium Leads have been a win-lose proposition as far as I can tell. The vendors win because they don't have to deal with lead and get higher yields. The users lose because of extra engineering time involved with incorporating this on their

I have an Electrovert Ultrapak 445 Wavesolder machine with 3 IR preheat zones and a single wave with omega wave. I want to run a DOE (Taguchi) to determine the optimum settings for soldering both single-sided and double-sided boards. Can anyone po

Is there anyone who can tell me what is the maximum allowable soldering temperature when soldering a TQFP (Thin Quad Flat Pack) device in a reflow oven? We recently used a CY7C375i in a TQFP160 package and we experienced warping (bending) of this com

I'll bet the rate of temperature change may be the problem. A large black thin package will heat quickly, and the package peak temp will be greater than what you measured on the board. The bottom of the package will heat slower than the top, creati
