MAY 2020 I DESIGN007 MAGAZINE 47 Gaines: I get few if any questions on our de- signs. As I stated before, I have learned what they may want and send them everything ini- tially. I do not want to be contacted about missing data any more than they want to take the time to ask and delay a job. I provide a folder structure broken into sub- folders that indicate who the files are for: one for bare board fabrication, one for assembly, and then others for PDFs of the drawings. There can be delays in schedules or even an incorrect product delivered because of un- known or incorrect expectations. Most expec- tations are not met by people because they did not know what was expected. Ask your board shop and assemblers what they need. Make a list and add things as needed. Shaughnessy: You said you recently worked with a fabricator who couldn't believe your complex data package was accurate and com- plete. They were used to being let down. How did people in this industry get so accustomed to being disappointed? Gaines: Over the years, they have been de- sensitized to the point that they just make it happen. I can imagine that a CAM person has learned by name whose job will have an auto- matic delay, with questions to be asked. These questions have to impact someone's schedule. Some shops have learned to set the delivery clock to start after all issues are resolved. In the dusty past, we had someone respon- sible for documentation in an engineering en- vironment. In today's world, the circuit engi- neer has become the layout designer, parts en- gineer, purchaser, and anything else that can be put on them. These great design minds are being put into a world totally new to some. People have learned that they may not be get- ting the best information and to adapt and fig- ure it out. Shaughnessy: What advice would you give a new designer just entering the field today, as far as making sure he or she met expectations? Gaines: Do your best to learn the expectations. Ask questions! Ask any possible fabricator/as- sembler what their expectations are. Make a list and follow it to send the same data out with every job. Also, as you grow in your job, come up with a list of what you expect from those supporting your efforts so you can quick- ly convey your expectations to others. Shaughnessy: Thanks for the insight, Albert. Stay safe. Gaines: You too, Andy. Thanks for the oppor- tunity. DESIGN007 For PCB designers, producing a comprehensive data package is crucial. This book describes exactly what a PCB fabricator requires in a design output package and explains the consequences of providing incomplete or inaccurate information. Learn effective ways to eliminate discrepan- cies and errors, ensure project success, and ultimately reduce costs and wasted time. Click here to download your free copy today!
