I would like to bring a Vtek Versacount II SMD counter on line but it is missing the tape guide. Can anyone give me some dimensions so I can have a new one fabricated. VTEK has been no help at all. I am mostly interested in the tape guide groove. I n

All, We have a conveyor that uses an o-ring belt , this belt breaks quite regular which causes a hassle for the SMD Ops. The stuff we use is from Radionics,its 3mm also. Anybody recommend a good belt or procedure for joining them together( we curr

There are several smd components in our factory that don't reliably wet to solder during reflow. Paste and placement are good, but the component won't wet reliably. All of the other components on the boards solder fine, but one of these components

Yea. I think that http://www.topline.tv/SMDnomen.pdf is even better. But the problem is that these two files was done in 1998 and from that time 0402 its not a prototype anymore its a standard. I would like to have this kind of document but more curr

Hello, On customer want to make a aluminium board. It will have SMD Led on it. Like I never "played" with this before can someone tell me what I know to know on that new thing. What kind of reflow profile we need. What just I be aware of, is

Hi Gents, I heard people having concernes by using 2512R SMD resistors due to potential solder joint reliability defect(CTE mismach among ceramic/alumina+solder+PCB) when soldered by lead free alloys (SAC like). Any experience/news about solder j

standard procedure for this would be to solder SMDs on the bottom side and the LEDs all at once on the wave - if the layout is ok for the wave. You would have to glue the SMD components, for this you would have to use a glue dispenser or a special hi

According to J-STD-033 Table 4-1, the bake out time to restore the clock to zero is not only determined by the MSL level, but the package thickness as well. Section 4.2.2 states "SMD packages shipped in low temperature carriers may not be baked in t

What are the opinions of the Assembl�on ITF Smart Feeder users out there? How is it about the mechanical endurance and relialibility of these feeders? Any particular issues with these electronic feeders? Any particular width that is more troublesome

We have started using QFN packages in large volume and are having problems with no-solders. We are using 6mil stencil with 1x1 paste print to pad. These also have thermal pads with thru vias that we reduce the stencil aperture by 1/4. Board also ha
