It's Time to End Class Discrimination

摘要

Discrimination is a hot topic everywhere in the world. It is even present in the electronics industry. It's time to get involved and stamp it out. Open up almost any industry performance document and you will find requirements based upon "class." PCB and PCBA performance has lived with an upper (class 3), middle (class 2), and lower (class 1) class for almost 40 years. You will find class 1, 2, and 3 requirement distinctions in almost all of the IPC's performance documents. This is a carryover from military standards where it was important to "classify" all prod-ucts.
