| Does anyone have angles on how to reduce N2 consumption at reflow process (i.e. process control equipment, etc.)? | | Any help would be appreciated | N2 consumption is very "machine" and process dependent. Some machine designs are better equipped

Here is some more info with regarding my Wave. 1. PCB .065" thick 2. leed length .20" (.135" protrution) I know this is high but we use many thousands and cutting each is not practical. 3. no clean flux by way of foam fluxer 4. wave machine is a HOL

Amen to that Patrick. I am from a traditional Engineering background myself - they never taught wave solder in school. My curriculum was mostly theory and labs. When I got out, I read all the soldering books available at the time and also watched s

| Can anyone tell me where I can get a good lightweight material to use for a soldering fixture? I need to make various fixtures to hold LED's vertical during the soldering process, and keep them from floating up off the board surface. | | At a dif

Thanks for the advice. We are experiencing only limited success with SMT on the drag. Problems are indeed bridging and misses on the smaller discretes. Works well on PTH as long as the pitch is not too tight. I'll have to justify a new machine. Rega

In obtaining almost zero defect in solder wave. I would like to suggest the following: First,We must consider changing machine if it is more than 5 years old. second, use the right tools for the right job. Most of the traditional engineers will us

Small waves are fine, biggest problem is the little to no preheat length. This is reason that complex boards cannot be soldered without defects. They also do not handle thick PCBas very well either because of same issue. Most of these "benchtops"

some lead free solders do not flow well and need encouragment. what are you using solder/flux wise and machine/settings including dwell times cheers greg
