Okay, we got the machine back together about 2 weeks ago, cleaned the clutches and measured the placement accuracy. We are back up 100%, and have not seen any stn 17 & stn 19 nozzle errors. Thanks guys!! 19 of the 20 clutches are really tight; they

I see what you're saying - I'm not a process guru by any means. I was going on the premise that SAC melts at a higher temperature than SnPb. Basically I think of it as a BGA is joining solder to solder, unlike an SOIC where it is tinned metal lead t

Scott: Pyros don't like to be heated, so soldering should be done as quickly as possible. Other tips are: * Keep pyro leads long. * Apply solder to the ends of leads. * Heatsink the lead, while soldering by holding the lead with a pair of pliers

Mydata machines are great for large back planes close to 23" wide. The foot print of the Mydata machines are concerning- being a "T" design it sacrifices floor space. Also, Mydata is not considered to be in the same classification (my opinion) of equ
