What standards (UL#xxx, CE, etc) is your company requiring be met when purchasing smt equipment? Is this a concern of only the larger companies?

Yo Dilbert, you don't say where in the real world you are located, but Ul, CE, and such pretain to electrical, and fire safety codes. The min required code is up to the local authority having juristiction over your facility. It is not a SMT industry standard

I suggest you look at the IPC/EIA J-STD-001C. It provides 3 different yardsticks depending on the end use of the equipment. Class 3 became the de facto military standard in Noth America since MIL-STD-2000A was withdrawn.

I have a similar question. What are the major differences between J-std-001 and IPC 610 class 3 ?

J-STD-001 is the workmanship standard. IPC-A-610 is a guide to evaluating conformance to the standard & includes photographs of compliant and non-compliant examples. In addition there is also IPC-HDBK-001 which expands on the bare requirements laid down by the standard. Class 3 calls out military/high reliability requirements.

I guess I asked the wrong question. For an OEM that builds electronic equipment that is used by industry in the production of pc boards, what specification(s) should the OEM be meeting for electrical safety? I have been given some paperwork that references NFPA 79, another document that is looking for equipment to meet CSA C22.1/C22.2 for Canada, then there's CE requirements............

Is NFPA 79 used/followed by everyone in the US? Is there a UL standard that they are compeating with?

I guess I'm looking for one "guide book" that will help me meet all the requirements.

Hi Dilbert We manufacture equipment for the electronics industry. The holy grail "guide book" you looking for does not really exist. I wish it did.

I got with our compliance engineer this morning for help explain since I am not that experienced in the codes.

All countries have legislation and codes that they implement to make sure items that are used within their borders are safe and no one gets hurt. In the states the main "group" is UL but there are different codes depending on whether it is a TV or piece of industrial equipment. In our case for the US it is UL508 for the electrical std. This includes alot of other codes that NFPA 79, 70 etc.. are a part of. Now the codes for the US are not required for all areas. Some cites or states do not even require it but other localities do. The best thing to check is your local government to see if they require it, some cities (mainly in California from what I have seen)specifically require UL stds to be met.

We chose to design our equipment to meet these stds since it calls out the best design practices for safety and operation and allows our equipment to be installed without an on site evaluation (if codes need to be met for that area) that the cost would have to be paid by the customer. After we get a new machine and we do a self evaluation we then call in a UL project engineer and a third party guy for CE testing (get to this later). The UL eng will initiate the evaluation and then a follow up procedure is developed. Basically a FULL machine functional test is done to meet the codes that the machine needs to be listed for. Once done and any issues corrected we can then label all future systems of similar design (this can ONLY be done out of the factory, unless inspected in field i.e... $$$) We also list ULc which includes Canada since they are very similar with US. Not all manufactures actually test and list UL since it is not required. Many companies design and build to the std just do not actual test. Or they may only have the electrical panel tested and listed.

On the CE side we have third party inspectors come in and check out the equipment to meet the stds. They will do a write up and we would have to correct anything to their findings. Once all done we can then self certify and place the CE label on it. For instance, we can not ship a machine from the US to Europe unless we have a CE label on it. The machine would not clear customs and the locality would not allow it to be hooked up.

Asia is a bit different right now. They don't specifically call out a full code yet but they are working on it, will be CCC. Like CE but with its own little differences. Right now we ship CE machines into Asia.

I know this is long but it comes down to that each region has specific codes they want met. Hard part is that they may be in conflict, UL wants a 3 pole hook up while CE wants a 4 pole.... and lots of other little things.

If you want to talk more in depth or talk with our compliance guy please email me.
