Hi, In general Tantalum D & E case packages prefers 12mm Reel with sufficient height. Make sure that no external force has been applied to the reel ( where it causes pocket deformation) thus leads to prevent smooth component release. Slowdown the noz

Hello experts, We have hard time with a tantalum capacitor challenging our 12mm feeder. Pocket seems to small for the part and parts are getting stuck and cannot be picked. In my opinion this part should use 16mm on 12mm pitch rather than 12mm tape

Sorry for stating this incorrectly. It should been: Bow & twist for bare boards and panels: IPC-A-610 Acceptability of Electronic Assemblies, 10.6: 1.5% for PTH only and 0.75% for SMT, acording to test method TM-650, method 2.4.22 IPC-6012, par. 3.

Simply go to Practical Components website and look in their catalogs. They give sizes in standard and metric.

Thanks Dave, The reason I want to make one in-house is cost. This is not a standard part and after contacting a couple of vendors ($1,000 plus for first tray) I decided it would be much cheaper to do it in house with our CNC.

What trays are made of? It depends. Look here: http://focus.ti.com/download/qlty/esh/Shipping_Tray_Product_Content.doc There no IPC standard for trays, but look here: http://www.esda.org/documents/S541FINAL-04-09-03.pdf ... and the reason you
