Parts date tolerance values | 11 April, 2018

Hi All, Sorry if this seems a stupid question but we been having a huge amount or parts rejected on our placement machines. I started looking at the placement program and found the part tolerance date seems to tight. Before I go and open the tolerance values is there a industry standard I can follow or do I need to check the suppliers data sheet for every individual part.

I don't think there's really any industry standard tolerance setting or value.

It's safe to open up the tolerances pretty wide as long as your placement accuracy doesn't suffer.

I require component engineering to spec in multi vendor parts as long as the following exists 1.Mechanical +/- 15% 2. Same orientation in pocket 3. Same pocket dimensions

I have to beat the engineering a few times per year but I think they have the message.
