I am trying to determine who out there is reballing devices below 0.4mm in pitch. We have been reballing as small as a 4-balled 0.15mm 4 mil ball diameter area array devices using an adhesive-backed reballing preform. 1. For such small devices we h

We have had this problem before, and Phil was pretty close. On the hydra where the vacuum tubes are connected to the tools shafts you should see a red light inside there. this light locates a lazer cut mark on each of the tool shafts, this lets t

The low value will be 0.624uF. You have to factor it from the low tolerance (-10%). So: 0.9 x 0.92 (machine tolerance) x 0.91 x 0.91 x 0.91 (3 decade aging factor for X7R dielectric). We factor hours at the 3rd decade (10,000 hours), but you can

We have inline reworkers, so this time has been factored in. We currently use Siemens S25/20 machines with M1 systems. The placement machines run a little slower than the AOI at times so there is time to perform review, most of the time. It's not

I have an Ersa Versaflow selective solder machine (single bath) which runs via a Profibus control system. I have checked all of the settings on the inverter, and all of the connections and outputs throughout the machine, but the machine returns a 68
