Are you working for an OEM? If so see if you can get your engineering department to change their "zero orientation" for the packages. At one place I believe the CAD department called them "G codes". What was really bad there was that one shape had

CKH, if I understand you correct, only some components(for example 2 from 10 parts in one reel) goes wrong. there is one more. How your machine alignes the components? Vision, laser or mechanicly. The problem can come from there. If the recognition

we have just started manufacturing a board which has surface mount components on side 1 and on side 2 all the thro hole components are d type connectors, (loads of them) the chances of these connectors inserted with the wrong orientation is very, ver

I think I read a thread very similar the other day but can't find it. If I remember correctly, the component database for that part was polarized and pre-orientation was used for camera inspection. It turned out that the optimization module in the

Hi Stephen, it seems they call it differently . What they need is an insruction data they can import to the machine, how the IC is soldered, the relative orientation for some parts,ect.

Dave, That's the funny thing, thru all that the output was pretty consistant with at least one bridge per board. * The ICs are going thru the wave in-line, according to IPC-782 figure 3-9, "Preferred IC Orientation". * Flatness of second wave is cont

it is one of three things: 1. tape and reel done improperly from second source tape and reel op. doubt if OEM would or could do this. 2. Program is wrong in machine,or part data is bad and part is noted as nonpolarized, maybe and the machine then h

Consider: * Printing: errors [ie, insufficient, excess, skipping, etc.] paste doesn�t roll in front of squeegee, paste adheres to squeegee at the end of stroke, paste does not release. * Component placement: orientation, wrong component, missing comp

Sometimes distributors endup with partial reels of componnts and are not able to sell the quantities of the partial lengths. So, they gather all the odd strips and have a contractor combine into a more attractive length reel for resale.
