Return to Resource PageEIAThe Two Edged SwordOften misused and misunderstood, EIA Standards are the RECOMMENDED STANDARD for electronic component handling, formatting and processing. It provides minimum guidelines designed to assure uniformity and compatibility throughout our industry. Most other tape and reel specifications are based on EIA, but not all of them. The easiest way to handle them is to read them and make sure you understand what is required. Unfortunately the best made plans of mice and men often go astray. Because EIA Standards are updated periodically, the potential exists for us to be using different revisions without realizing it. Since EIA Standards are not always backward compatible, it is important to know what standard you’re using. If you don’t know how to get a copy of EIA Standards they are distributed exclusively through GLOBAL ENGINEERING DOCUMENTS. You can find their website here==> http://global.ihs.com . This site is in English, but there are links at the upper right hand corner for our French and German friends.If you want to be notified when a standard has been updated and stay up to date on upcoming changes and trends you can subscribe to another free newsletter here==> http://www.ihs.com/engineering/subscribe-newsletter.html.With Tape and Reel, we usually limit our concerns to the standards that directly apply to us: ANSI/EIA-481-C – FOR SURFACE MOUNT TAPE AND REEL ANSI/EIA-296-F – FOR AXIAL TAPE AND REEL ANSI/EIA-468-B - FOR RADIAL TAPE AND REEL Then there are the related documents: ANSI/EIA-726 – ADDRESSES COMPONENTS SMALLER THAN 2.0MM X 1.2MM ANSI/EIA-747 – ADDRESSES ADHESIVE BACKED PUNCHED PLASTIC CARRIER TAPING OF DEVICES LESS THAN 1.0MM THICK ANSI/EIA-763 – ADDRESSES BARE DIE AND CHIP SCALE PACKAGES ON 8MM AND 12MM CARRIER TAPE ANSI/EIA-625 – ADDRESSES HANDLING OF ESDS (ELECTROSTATIC-DISCHARGE-SENSITIVE DEVICES) IPC/JEDEC J-STD-033 – ADDRESSES HANDLING, PACKING, SHIPPING AND USE OF MOISTURE/REFLOW SENSITIVE SURFACE MOUNT DEVICES There are more. In fact the mountains of standards that exist demonstrate the need for all of us to remember some basic concepts: First, remember the person reading your Purchase Order can’t read your mind. I know I can’t. We received parts from a customer one-day – TSOP 54’s in trays with no specific instructions on the paper work. So, we tape and reeled them. I don’t think I need to tell you what I was thinking when the most anal buyer from the most snotty ISO certified company said something like: "Well, you should have known I wanted them baked and returned in tubes!" Trust me, it doesn’t work like that.
Second, tell your vendors what you want to accomplish. If you don’t know the 50 cent phrases, ask a lot of questions. Questions are easier to deal with than rework. Third, be specific about any standards you want them to follow. If you still use EIA-481-A (circa 1986), you really need to tell your Added Value Service Providers. Fourth, tell them when you want it. Putting "ASAP" or "ASAP or sooner" as the due date does not help, especially if you don’t need them for 2 weeks. Have some mercy on your supplier. If you really want to complicate things then put a date that’s 6 months away when you need them next week. Believe it or not, these are probably the four biggest time wasters in the world. The fifth (and final) one is similar though; PUT A COPY OF THE PURCHASE ORDER & WORK ORDER IN WITH THE PARTS! We get parts with no paperwork - I mean they only way to track down who sent them is by the Tracking Label. We get components with notes like "do what you did the last time" written on a torn off piece of paper with no readable name. We have had components sit on our NCM shelf for over a year waiting for somebody to claim them. And I know many of you will find this hard to believe, but usually, given a choice, we’ll do exactly what you didn’t want. I know all this makes sense, but of the 160+ active customers we serve, only 1 sends us Procurement Documents that follow the EIA standard they want! Most buyers never know that EIA typically identifies the MINIMUM amount of information you need to put on PO’s and Work Orders. Life is too short to complicate it with disasters and misunderstandings. So the most important thing you can do is communicate with your vendor about your needs. If you don’t have a clue what you need, a reputable tape and reel house will work with you to get you on the right track. That’s why at Advanced Component Taping, Inc. we have a SPECIAL INSTRUCTIONS SCREEN for all our customers. Whenever we receive work into the system, customers with special instructions or requirements have them displayed on the screen. For customers with drawings or other documents, we link those files to the SPECIAL INSTRUCTION SCREEN so the information is available to any supervisor from any computer terminal.
