Time. The virus does not last a very long time on surfaces. Not sure how long but I read that it does not live long on copper but does last on stainless steel. As far as I know the virus lives as well on gloves as it does on hands. So you still have

Panasonic has a great training facility in Kentucky that could be of enormous benefit to you and your team. Materials and Lasers range in capability. Generally speaking you need good contrast; which is not always guaranteed with bare PCBs. As othe

Hi Dave, To close-loop or not to close-loop, that is the question� I can not speak for all machines, but in our case, close-loop systems are actually less costly to operate than open-loop systems (we make both). First, determine the volume of wate

Larry: I've got extensive experience with solder skips on both 0603 and SOT23 devices. We also installed an "Omega" vibrating wave on our machine, but it didn't really have an impact on solder skips. The major difference that the omega makes is in

I would be afraid to have this kind of basket holding my boards. Yes, in most cases, you would not get damage if the boards were closed inside of a good, metalized (silver colored) ESD protective bag. The problem is that the boards usually have to c

| We've recently encountered this problem where one of our .050" pitch BGA's were reflowing at the wave thus causing shorts... The board was profiled with probes stuck to a QFP solder joint, an 0603, and one of the BGA joints. There was an almost 7

| We're getting field failures in a high impedance portion of the circuit. Think the unpopulated pc card has contaminates because we were able to grow dendrites by applying a 9 volt battery across the suspected pad, placed a drop of de-ionized water

I�m aware of no such standard. There may be something in Euroland [ie, IEC, etc.] TM-650 �Test Methods Manual� has procedures for measuring various types of contamination, such as: * 2.2.25 �Detection Of Ionizable Surface Contaminants� * 2.2.27 �Cl
