Marlies, The terms are one in the same but are used according to how you descibe the situation; i.e. centering refers to adjusting the part where as aligning normally deals with adjusting the vision. NOT THAT THIS IS A RULE. ( different strokes...

| Dew: | Is this the third or forth software alignment for Fuji? Hope they stick with Unicam for a period of time... | Just my two cents.... I believe it's the forth, MCS OS/9, MCXE,F4G, and now fujicam...were there any others I missed? Personally I

If you are doing this in a high volume, you could concider using a pin transfer method. Apply solder paste first. Have a plate made with retractable pins in the location you want to have the adhesive dots. Dip the pins into a lake of adhesive. Align

They have there strong points and weak ones. I have worked with them for the last 5 years and have seen some flakey problems (Cables, feeders, encoders) that will cause you some down time but if you get a good price on a system it might be worth it.

We haven't run a profile yet....probably because we're a-feared to. We can't do topside preheating here to any degree because we use an aluminum plate for aligning hundreds of top side through-hole components (pots, switches, buttons, LEDs) that te

One thing that will also cause this is very slight stencil mis-alignment. Sometimes the paste will have a tendency to hang up in the apertures if you are over hanging just a little on the solder mask. Some solder mask are very slick and will not pull

It depends on what the finished solder joint looks like after reflow. Use IPC to determine your solder joint acceptablity and check for solder shorts/solder misses to determine how far our of alignment you can go. Hope your not working with theta o

We have also had this problem. I have managed to get around this by selecting a teach video model and positioning the teach window to include half the pad on the left and half the pad on the right so that the center point is bang in the middle of the

Dear sir, I think so with every idea , everyone is correct , paste , pattern of pad design ,profiling or solder mask on PCB ,and one of the cause of tombstone that I found is alignment of machine placing and solder printing , from my experience many

so the first PCB if i want to aligned with stencil is manual the same for screen printer without vision and vision starts work for next boards? or i am wrong? but if i make mistake during aligment process for the first PCB i will repeat it for next P
