Pete makes great points. Taking a slightly different angle, use your placement equipment's software to help you. It keeps track of the number of picks and attempts for each location. Study these numbers for a week and determine the capability of p

Hi, You can't void of loose parts. But can reduce. You can ask your Lead operator or the the person in charge for that individual line to keep track on the hourly monitor. If they tracking the number of PCB went thru the machine (getting the coun

Good Morning All, We are in the process of setting new attrition rates on SMT components. Initially, we will be setting a rate accross the board for SMT components. We realize that a per part number system is far more accurate but at this time, some

If you are referring to SMT chip components, 3-5% is the norm. BUt for some critical items like IC it usually applied as one to one exchanged if it is the component's defects. If the defects cause by processes, then manufacturer had to replace you .

This may be a really silly question but does anyone pick up and hand place the reject parts from the scrap bins of the machine? My attrition rates are out of control and i think this would not only highlight the problem but also save oodles of money

Attrition... how to measure it?

Hello guys I hope you can help me, I had worked with machines that usually tell you how many components are dropped off, now I have some very old machines without such information, any idea how to measure if attrition rates are normal? I expect to be

Dear all, One of the major reason is that some components have curved shape terminations and thats why their attrition rates are high. So CORRECT THEIR VISION FILES OR IF PROBLEM REMAINS THE SAME THEN INCREASE THE TOLERANCE OF THAT COMPONENT VISION
