SMT: Zulki’s PCB Nuggets – ECOs Reviewed – The Importance of Accuracy
Engineering change orders (ECOs) have been part of the product development and PCB landscapes for as far back as one can remember. Particularly, when it comes to ECOs for PCBs, there are varying and endless reasons for these changes.
Certainly, PCB designers can perfectly layout a design and, in theory, follow written specifications to the letter and to the best of their abilities. But when you factor in the practicality of that design, virtually everything associated with it has its limitations, ranging from the material used to make the circuit board to assembly, machine tolerances, process limitations, and the list goes on.
