Actually, some of the off the shelf coupons are a tiny bit skewed, which doesn't really affect the measurement, but this makes printing solder paste very interesting. Also, the IPC's artwork does not include a file for a solder paste stencil. I usually make my own artwork from the details given in the test methods.

That means the data file (holding the locations of the apertures) and the apertures shape/size file are separate. Several PCB and stencil design programs can read 274D by importing first the Aperture.txt file using the appropriate library information followed by importing the data file. A more modern and easier to read combined data/aperture file comes as Gerber 274X and has the extension *.gbx. Let me know if you need any help. Having fun, Ahne. 503-970-9814 -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Glidden, Kevin Sent: Monday, February 22, 2010 08:24 To: [log in to unmask] Subject: [TN] Reading IPC-B-24 data issues Good Morning, I will preface this with a statement that I am not a PCB designer, and I do not run the PCB design software we use. That being said, I am attempting to have IPC-B-24 PCBs made by our PCB vendor instead of buying them off-the-shelf. I purchased the IPC-A-24G artwork direct from IPC, and it came on a disc. Two PCB houses and the stencil house have all responded it is unreadable. The disc has ZIP file with the following: IPC-A-24G Master Drawing (PDF). This indicates original design was done by Magnavox in 1990. Dcb24l01 Dcb24lst cd2401.gbr dc24lst.gbr Aperture.txt My PCB people are telling me the files won't even auto-import (automatic format detection) into CAM software. Has anyone else run into this issue and know a solution?
