I think this can be of help when dialing with setting up feeders for product prototyping, where often we have to dial with a short quantity of components (often pieces of carrier tape w/o tape and cover leader) just enough to run (if lucky) those few

We have issues with the Philipps Luxeon Rebel LED where the part sticks to the cover tape during advancement. This causes the part to get flopped around in the pocket or the component gets dropped and damaged when the feeder advances. Has anyone ex

97% to 99%? I've heard of one company that managed that but only after a big six sigma project. And they had minimal stock anyways. I think if everyone picked 100 components to cycle count, that the average accuracy would be around 80% . That is

Years ago I received a sample of adhesive dots that were on tape and reel and could be pick n placed with standard equipment and withstood reflow. I have a current need for these and cannot remember a vendor or manufacturer. Does anyone know of this

We have had this problem in the past, On paper tape resistors(old stock from before i took over and forced rotation on everything) and on embossed (national semi parts, strings of glue pulled back like seat belts across the pocket.) For the national

Apparently the adhesive tape peels off from the joint, which could have some reasons. 1. There should be an overlap of the cover tape, as Cal mentioned. The new cover tape laying over the old by approx. 2mm. I also peel the cover tape a bit off, whi

We've had poor luck with leaders - inefficient, not cost effective for the price of the parts usually. In my opinion, your best bet is to over-issue parts to a scrap # that works for you (all feeders are different as are machine scrap rates). This

Thanks for the reply Rob, This we already do. The machine will pick from the most efficient available feeder (assuming multiples of the same part number)...so when you remove the primary it will seemlessly move to the next available. When you re-in

Hi Greg, We've used lots of machines over the years & seen lots of different tape related issues - the main one being snap off of the cover tape, usually due to too much glue, over entusiastic heat seal, or a feeder requiring maintainance. Also the

Thanks for the insight, we will have to look more in to them.
