Hi Pascal, 0,65mm pitch normally isn�t much of a problem. With 90�m CU I don�t have any experience but would like to know what deviation from nominal value for the pads you get with different PCB-deliveries. In short, for the standard Cu=35�m we se

Does anyone have a solution to using thick tape on quad feeders? The feeders are not strong enough to handle the thicker carrier tape. This causes much downtime and frustration.

Not sure what you mean by thicker embossed tape. I've only seen one thickness as far as the tape, but I have seen electrolytic caps on tape that were too tall for the feeders.

Especially on capacitors, the tape is so thick that the motor starts to slow down and does not advance the parts fast enough or not at all. This happens on regular 8mm.

Are these 12 or 5 volt feeders?

Yes we have done that in the past but this time it did not work well.

That�s a 672 BALL BGA, bud!!! It�s a BIG Mutha!!! [I know. I know. For some reason suppliers call balls "pins".] Let�s focus on: * Clarifying the units on your PCB and aluminum plate thickness measurements. * Describing your use of the aluminum pl

I have experienced this problem on the Quad thinpro feeders only. I have not had any issues with their standard feeders.

The feeders have 8 pins, so I believe they are 12 v. But will double check

Some guys used to hang weight on the spent tape with a binder clip to help pull the tape through. Not ideal of course, but may help in a pinch...if you try it, you'll have to move the weight(s) up every so often.
