    I was looking around Google but couldn't find a good answer. What does attrition mean with regards to PCB manufacturing? We were short some components on our BOM and the person handling our quote said "this could cause low attrition."

    My best guess is its referring to the life cycle of the electronic components.

    you mean PCB assembly?

    During the assembly process, pick and place is not 100% perfect, especially for components that are small. As a result, you need extra in case there are mess ups. If you fall short due to a component shortage, you hold up assembly, so you hold up your order. If you hold up assembly, they will simply move on to the next job and you will get delayed until the issue is fixed and they will not jump on yours until the next business day after the issue is fixed.
