Yes we are in alignment of thought on this. Deciding on a value point of keep/toss is always a challenge - availability also comes into play - but this has improved over the last year. This is a matter of - when you do want to keep - short tapes/part

We are building our own products and we tend to keep our strips in bags. The same goes for bulk bags. What I would do, should there be no management issues, is to throw any bulk/strips of resistors and capacitors away, as any additional handling giv

We are using one BGA that has 7 mil bumps on a 20 mil pitch. We use the manufacturer's recommended pad and aperature layout, which is an 11.8 mil square overprint on a 6 mil land. At 11.8 square, you need to use a 4 mil laser cut or a 5 mil e-form st

Actually, Mydata already had that similar design over 10 years ago, it's the aglilis feeders. It's easy to set it, and almost no spill parts at all if the operator do it right.
