Can anyone tell me what he overall height of a CP6 board support/backup pin is supposed to be? They don't sell the back up pins as an assembly. It looks like you have to buy them piece by piece and set the height yourself. Thanks

Hi, I am having some problems with my Fuji CP6 placement repeatability. The placement drifts during the build about .06-.10 mm on parts. It has happened on several different builds this week. It is enough to cause some defects after reflow on smal

For package shapes/names I would recommend using manufacturer names. This is much safer than coming up with descriptive names like QFN32_5x5 as there are multiple 5mm 32Pin QFN shapes even when pitch is the same, this makes it safer to use a name in

| We have a Vitronics SMR400N oven and many times need to use N2 inerting. My problem is that it takes close to an hour of operation to purge the system to achieve the desired O2 levels (~40PPM). This is not only time consuming but results in an inor
