Hi Yes DavidF I agree, and that is what I think I am reading in the orginal and follow on post from the poster. I think this problem is just below full failure to solder which was your point, I think. You, and I particularly, are taking opposing y

Hi As I got thinking about your problem, as you stated it, I am wondering if maybe we have some oxides or too thin of a Gold Immersion layer so that some of the underlying NI is being oxidized. The colorization that you described is what intriques m

Tact time is a poor measure of your throughput capability. The Number of boards produced per hour or shift or 24 hour period is the true measure of what you are really doing. Your theoretial "tact time" can be used as a metric to judge performance,

Hi You really received some good replies. It seems like the best replies are a BLOW to one of your engineers, at least from a terminology view point. "No cake tonight". Yet it doesn't mean (s)he is better or worse than the other. Tact Time from a

Hi I don't know your PCB, circuit, or product application, and probably should steer you to at least the ESD Association http://www.esda.org/ for one place in case you find anything that you really love. I do know some of these people first hand and

Hi Read those guides again and then give IPC a call to see if they can direct you to any other materials. This stuff is quite old so they should have lots. The Mil does also. IPC does have a Designers Council that serves your area. Give the leaders

Hi,mantis, I has experienced this case.when we run a model ,misalignment and tombstone of some 0805 resistors and 1206 caps always occured.we have taken many actions,such as adjusting reflow parameter&printing parameter,checking pcb and parts soldera

AccuFlex is the replacement for UltraPrint 1500. UP1500 is going obsolete. AccuFlex was desgigned for fast setup and changeovers and takes some tasks away from the operator. The UltraPrint 2000 was designed for high production, even though many users
