We have few questions for BGA assembly. Specially with Fuji machines. 1. What are the testing mechanism other then X-rays. 2. How we get data from Fuji to check repeatability and reproducibility in terms of percentage and how it as calculated. 3. Do

I am trying to place an LQFP 208 with the fuji IP2 but I repeatedly get an error stating that there are too many leads. I have gone over the part data and started from scratch multiple times with the same outcome. I was hoping someone may have some p

I have used fuji XP series for about 3-4 years now. We have XP1, XP2 & XP3 in our Prototype Dept. Excellent machines for this purpose. Very easy to program, can edit at the machine, placement, repeatability, reliability is just like any other Fuji

Can't help you with the machine, but have you considered stencil printing? I have found that this seems to be a better (more repeatable) process than the dispensers I have used in the past (FUJI).

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

Thanks Mike Honestly the whole subject of repeatability is Is confusing i.e. I do perform placement tests using glass plate�s Fuji IP3 and Pam on the Fuji chip shooters which calibrate to 3 sigma but I cannot guarantee placement repeatability As y

You're welcome John, it can get confusing but what's important is that machine's exhibit accuracy AND repeatability. Generally, high Cp values represent high repeatability (for instance in darts: hitting a triple 20 over and over means you're very re
