Component Feeder Sizes | 17 June, 1998

I am involved in the purchasing decision (Technical side) of which placement machine to buy. One of the criteria we need to specify is how many feeders, and what sizes. I have a provitional parts list of a job that we are most likly going to build. The differnt types of SMD's are as follows, 0603,0805,1206,PLCC 32(device),PLCC 28,32&44(carrier),SO8, SO14(wide body), SO16, SOP32, SOT23, SOT223, TSOP20. What I need to find out is "What type/size of feeder is requied for different types package. Any pointers will be appreciated Regards Terry

Terry: Not sure what P&P equipment you are thinking about, but suggest that you contact Hover-Davis in Spencerport, NY. (716) 352-9590 and speak with either Sue Wise or Doug Green. Sure they can supply you with technical information and product literature that would be very helpful. You can also look at their website at: www.hoverdavis.com Wayne We are a manufacturer's representative company in New England and if you would like us to mail you information, just ask.

Hover Davis is a good suggestion and they make outstanding feeders. Try EIA-481 for standards for tape sizes versus component sizes. This is pretty much the industry standard.

The "Setup Sheet" for the machine should list the actual feeders that need to be ordered. The topline catalog or website would also be a good place to go for this type of information.

I've done this spec. twice and: You'll run out of 8mm feeders on some jobs. You'll always have a few 12, 16, etc. mm feeders on the shelf. You'll run out of Vibrator feeders. Trays are always an issue, regardless... Murphy rules in this. My advise is worry about the 8mm, get enough to load the machine 80%+. Get enough of the 12,16 etc. to feel comfortable (4 or so of each). Pay CLOSE attention to the loading forks for the vibrators, at any given time you'll need more than what you picked and the mix is not predictable... you'll cut more than one top off a tube to "create" a fork. I hope this helps. Whatever you do, just know you did your best and don't look back. Cheers, Scott
