What is the source of these attrited components?

What numbers do you all use for component attrition at your pick and place machines? Thanks, Larry

Mark, On most chipshooters that have a few years of use on them you will find the feeders play a dramatic role in component attrition. I don't know the panasonic software. On Fuji you can get a breakdown of placement errors in different forms.

WHERE DO WE LOSE MOST COMPONENTS? MACHINE? OR DURING SETUP (INTO FEEDERS)? IS IT POSSIBLE TO REDUCE MACHINE ATTRITION(THROWOUT)FOR SMALLER COMPONENTS SUCH AS 0402'S AND 0603'S? THE MACHINES INVOLVED ARE MSR'S AND MV2F'S(PANASERT).

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

I am currently trying to creat a model to calculate attrition on our SMT line. A new product is coming into our cleanroom and we have problems with the current product and atttrition levels. One of our main problems is a large batch for us (space ind

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

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
