Is it just like that "smart" golf ball - where you tell it, "stop!!! stop!!!" ....or "go further!" go further! So this smart solder, you can tell it "don't skip!! don't skew!!"

Oooo, you are waving 0402. Tell us more about your wave and its set-up. Never seen this [knock on wood]. When is this skewing occurring, after placement or during cure? What�s the distribution? What happens when you slow-down yer placement rate?

Is the glue intended for printed SMD attach? 3 Are you following all the manufacturer�s glue shelf life recommendations? 4 Are you observing all the manufacturer�s glue working life guidelines? Finally, what level of skewing are we talking about?

For reflow, low soak time and low peak temperatures will help reduce the number of components skewing Search the fine SMTnet Archives. For instance: http://www.smtnet.com/Forums/index.cfm?fuseaction=view_thread&CFApp=1&Thread_ID=6071&mc=15

to use local fids such as this you must use the cad data, when the machine knows where it is supposed to be and seeks there it reads where it (PCB) really is and then corrects the machine, it does not have to be symetrical at all. If you teach fids

Good afternoon, We are running some aluminum boards through a 7 zone reflow oven which have 2 4 pin right angled headers on the ends that are skewing. Does anyone have any suggestions to prevent this from happening?

hi Team, observed component skew during reflow process. Inductor location. I have attached the image for the same. Please provide your valuable feedback. Attached are the images for the same. Its SAC305 alloy , R0L1 flux chemistry. Regards, Am

I noticed that your solder mask registration is off some. Does it cover a significant portion of any of the pads for these parts? If so, is it possible that the surface tension of the solder at liquidus is enough to skew the part when the solder i

I prefer mine skewered with a remoulade, yum. IPC-A-610 allows component side overhang to the lesser of either up to 25% of the component termination width or up to 25% of the width of the pad for Class 3 devices. Help us understand your problem.

I have two questions 1. How do I control the skewing of FETs/power regulators ? ( the one's with the big rectangular pad and two smaller one's for the leads).If I go 1:1 with the apertures I seem to get solder balling and when I tryed to minimise th
