Yes indeed you make great point as well, we also run low volume production as well as some high running stuff, seems as though some type of combo nwould be best, maybe something like 20 pieces over or 2% wichever is greater maybe? Russ

Depending on what kinds of machines you run and feeder style, self adhering leaders work well to minimize the need for a long leader. We use them on every reel. We can generally load most feeders with only waste of about 4 parts by use of leaders (

Just as you will not find such a specification for SnPb solder, you will not find such a standard for SAC. We talked about solder strength several times previously here on SMTnet. Search the fine Archives for others comments. For instance: http://

Thanks Jerry. It's entirely possible that the parts that were originally kitted were Yageo so we at least have some chance of things being "as they should" on the bulk of them. Those also test out at 10.00 so we're not too concerned about them. The o

Sorry, Jerry, I was just too lazy to include the k, as in 10.00k ohms. I don't have a meter that will read out to 3 places, so something like 10.014 would read at the upper limit of 10.01. Same problem exists at the lower end, obviously.

I would get yourself a better meeter. All resistors are sorted as far as I know so if you had a good meter you could just grab a reel of 5% parts and sort them your self. I have seen the markings both ways so I would not immediatly assume the parts w

We have solved our MCSB problems by using standard homeplate designs on all of our resistors and caps. I use a 50% taper and have achieved great results with 0402-1206 parts using both tin/lead and SAC305 paste. We use Amtech paste.

hi Dave.F and All, I need to reflow SCA solder balls on Sn/Pb paste, i get a pretty OK solder wetting and collapse apperance, however, i am seeing voids everywhere, some of them is greater than 25-30%, which has exceeded IPC standard. Please advise.

Well, the monitor isn't touch screen. The light pen IS the mouse/trackball. If I touch the screen nothing happens. The industrial PC has no PS/2 ports of any kind on it. Perhaps I could splice into the light pen connections and connect a standard tra

Thanks for the replys guys. There is infact a serial port in the back. It is COM2. I just had to plug in a standard mouse with a Serial to PS/2 converter and enable the mouse to use COM2 in the Windows control Panel. Works better than the stupid ligh
