Depending on the time of day, there are two worlds that exist in the same physical space: streets that appear gritty, dirty, and depressing by day turn into an environment infused with a strange kind of lush, dark beauty and romance at night. Here in Seattle, she is currently affiliated with the SAM Gallery.Ībout her work, Kate says: “I have a love/hate relationship with the cities in which I’ve lived. Protage regularly shows her work at galleries in Seattle, San Francisco, Philadelphia, Princeton and New York.

Eventually she found her way back to her passion, and set off for New York where she completed an MFA degree in Painting with academic distinction from Pratt Institute. Initially she received a BA degree in Studio Art from Smith College, but soon after that began a career in advertising and didn’t pick up a brush for the next decade. This led her to crave more urban environments as an adult, and sparked the beginnings of her paintings. Growing up, her family moved through more than 18 different places of suburban sprawl. And when you upload your design in ODB++Design format to the manufacturer, all thickness values are in the file – for both through holes as well as for blind and buried vias.Kate Protage is a Seattle based artist exploring dreamy environments through her moody cityscapes. PCBflow was designed to eliminate aspect-ratio uncertainty: When you run DFM checks against your manufacturer’s capabilities, you can safely assume that their relevant aspect ratio values are set correctly. You, as the designer, may not know the relevant aspect ratio capability of your manufacturer, and the resulting uncertainty may result in additional, resource-consuming design spins.

Unfortunately, this is a manual process, and is prone to error. So, in order to properly verify the aspect ratio, these values should be communicated to the manufacturer.

While the hole’s diameter can be obtained from the design data, the board thickness and material (copper and dielectric) thickness values are not included in the Gerber data – as they are not part of the format - and are usually delivered in the documentation or in a drawing.

But here’s the challenge – both the designer and the manufacturer are missing crucial information: Usually, the aspect ratio is checked by the manufacturer as part of the DFM process. With all this uncertainty, it is very important to verify that your design is suitable to your manufacturer’s capabilities in general – and to their aspect ratio in particular. And of course, each fabricator may publish a different set. Aspect ratios that are higher than the maximum supported by a fabricator may result in insufficient plating of the hole, which, in turn, will result in a broken net in the case of a via hole, or in assembly failure in case of a component plated through-hole.įabricators usually publish a set of maximum manufacturable aspect ratios for multiple processes, such as through holes and microvias. Aspect ratio is particularly critical for ensuring a consistent plating process: the smaller the aspect ratio is, the higher the probability of consistent copper plating throughout the length of the hole.
