Hello all! Can you tell me what is the allowed offset for placed SMD component? Let's say for 0603 package(1.5mm,0.75mm the offset could be 0.2mm in X and Y ....) Where can I read about it? Thank you in advance.

The mydata machines are using different packages. Since we know the part numbers and packages affected, would it be posible to load some sort of offset file to correct this before sending it to the machines?

I don't have CircuitCam, I'm using Unicam with Mydata. In Unicam I have a Theta Offset setting for each package witch determines the default rotational angle with respect to the pin 1 setting within the package data. With Mydata, the package inform

Hi, We already export in plain ASCII format with the PCB dimensions, coordinates of all 4 corners with respect to the origin, circuit repeat offsets, and Centroid data with RefDes, X, Y, R, Part No. and Package information. However many customers ha

Tape feeders usually have a fixed pick position regardless of the package size. Is the component body off center in the tape pocket? I hope you can enter an offset in the feeder set up file. Also, perforation holes can deform, if the reel is too hea

http://www.freescale.com/files/32bit/doc/package_info/AN2920.pdf hopefully this help you. also we always look on X ray for some misplacement; you can see like a dark circle and another lighter circle with an offset between both circles (meaning dar

I recently did a layout for a Freescale accelerometer and the mfg recommended pad layout did something similar. They where very specific in the pad layout dimensions. They stated the reason was "With the correct footprint, the packages will self-alig

First groupe of questions: Is your machine have one head with multiple nozzles? Do you have separate vacuum tubes for each nozzle? Do you have problem with the same package or with all pakages. In your PNP machine, what are the dimensions tolerances

I guess, since nobody is using local fiducials anymore, we forgot how to program the fiducials. Was it in the component-package file or in the placement file? Nevertheless, once you find the place, where you enter the fiducial position, you'll find t

Thanks for the comments everyone. I did not think of checking the nozzles material, I will check this out. GS, What is PBM, is this some sort of ironiser. Also to clarify, we believe the that the pocket size for the component is too big allowing th
