Here is a good one for ya. Our IP3's MTU will not pick QFP240's out of cavities, 10, 12, 13, 15. This is a 3X8 tray. The listed cavities are also the closed cavities that are used for tray eject. There is plenty of vaccum, the nozzle comes down f

I think you needed an IPC Class 3 annular ring because for very dense designs, the smaller the annular ring the better, as less space is taken by the pad or via and more space can be dedicated to routing the traces in highly populated areas of the bo

A solder wetting balance will indicate a time of less than one second for wetting to occur to a solderable surface. The additional time is required to get the metalized surfaces up to soldering temperature. A single sided board has very little mass a
