Yes, you can get a class 2 PCB and then also receive class 3 workmanship on the assembly but you can't expect it without a contractual agreement.  Other industries that may use class 3 are medical, veterinary, and any other device that must have high reliability or that may cause a health/safety risk if the device fails.

I am looking for your opinions and experience.
IPC has the 3 levels of classification for the Acceptability pf Electronic
Assemblies, and IPC also offers 3 levels of classification for the
fabrication of Printed Circuit boards.

My question is this- Can I purchase a Class 2 Fabricated Printed Circuit
Card, and Expect to get Class 3 Workmanship Solder Joints from Manufacturing
Wave Soldering and Employee Hand Soldering?


One additional question, Other than the Military and NASA, what kinds of
products do you feel require the guidelines of a Class 3 Board and or
Assembly.


Any input is greatly appreciated.
