Ideally we want to mix the same lot numbers in a repackaged tube. Once again, these are partial tubes that have been thrown away. If the ratio is right to begin with the only change would be due to air exposure. Semco makes a TC seal which, if we

You can buy plenty of paste height measuring systems today, ranging from full 3D laser systems to systems using an oblique light line which will measure the paste height only. I found that the lowest cost option was to attach a DTI to the focus contr

Well my process is I'm running my belt speed at 3.50fpm and about 215 to 225 degrees top side. I got my main wave down to a little less than half the board thickness. I'm not using a hot air knife cause we thought it might create more of a problem th

If your words imaged correctly, it seems a bit strange to have a trace that is wider than the pad where it connects, because we�re used to seeing a narrower trace connecting to a wider pad. It�s tough to determine what the designer was thinking abou

Regarding your comment "technology doesn't seem to have improved". Actually, technology has improved significanty. Cyber Optics uses a line measurement, a new unit from Germany uses sine wave differential measurement. The Gridmeter unit captures a vi

Hi Yngwie Have you got a reflow oven yet. If not, forget about complicated profiling with test runs or reflow trackers. We've got a nice oven with integrated temperature-feedback system. You build any profile you want and the oven will adjust its hea

Bruce, Using a foam fluxer with no-clean flux is a very touchy situation. It is imperative that the specific gravity of any flux be maintained within the manufacturers recommendations. If it is not, you will get icicles and bridging. Maintaining the

It all depends on what type of board you need to solder. If your boards are small in size and low thermal mass and your conveyor speed requirments are normal, then I'd say the OmniFlo 7 will do the job. It has a max zone temp setting of 280C. The cur

Rob, Are you hinting that the lead content of this component with dipped tin/lead solder would not be an issue with RoHS? If so, our understanding is that the legislation requires that the 6 banned substances cannot exist at greater than X% in any
