Hi all I have a CS-300E component locator machine. I am looking for the password to get into the "CONFIG SYSTEM" area. I'm not sure if it is the same on all the machines, but I figure someone on here may know. thanks greg

I am having a problem remembering what temp to pretin components at. This is for SN63. I thought I used 450F, but this company says 500.

Kevin, Agree with John's thoughts on profiling and the max temp of 240 degrees in particular. To add to it a bit we have seen the following parameters put in place at many assembly houses to protect against overcooking the components: --Time above

I believe the Delta T you're referring to is the delta between the highest and lowest thermal mass components on the given assembly when being processed through reflow.

So how much clearance between components (in mm) does the Ersascope require? What if you have caps around (2-3mm from the BGA's edge) a BGA . . . is it necessary to remove them prior to inspection of the BGA?

Does anyone have a listing of recommended usage requirements on SMT components. Can you use SMT resistors which are over 3 years old for example ? Can you use ICs which are not known to be moisture sensitive but which are over 5 years old.
