CE compliant information

Thu Oct 15, 2015 8:09 am

We used the compute module on our product and we have to certify the product CE. To do this, we would need information about the construction of the PCB’s compute module: the class of flammability, clearance, creepage distances, electrical insulation. Could you send us these information? Thank you.

Thank you for the reply.
The links do not refer specifically to the compute module. Do you have any documents or information about the construction of the PCB’s compute module?
Thank you in advance

I don't understand why you need this information. Flammability, clearance, creepage etc. This module in intended for ELV circuits so non of that applies.

FCC covers only EMC and radio spectrum matters for the US of A, doesn´t say anything about electrical safety.

Dear Dougie, we checked our seller's website and we asked the folks who sold it to us, but they answered that they have no access to this information.
So, we analyzed the silk screen on the PCB of the compute module and we found the number "E305654 RU" which corresponds to the following UL file:
http://database.ul.com/cgi-bin/XYV/temp ... sequence=1
concerning the company SHENZHEN XUNJIEXING CIRCUIT TECH CO LTD: could you then confirm that this is the producer of the compute module?
Another question. On the PCB compute module there is the silk screen "94V-0" below the code"E305654 RU": could you confirm that the flammability class of PCB is V-0?

Thank you

Try using a blow torch :roll: :roll: :roll:

I've no interest in how those certifications are done or policed.

Dear Dougie,
Sorry , but we were wrong to address to you the question.
The question is addressed to someone of raspberry team.

Someone of the raspberry's team with technical and certification expertise regarding the compute module, can kindly answer these questions?
We used the compute module on our product and we have to certify the product CE. To do this, we would need information about the construction of the PCB's compute module: the class of flammability, clearance, creepage distances, electrical insulation. We analyzed the silk screen on the PCB of the compute module and we found the number "E305654 RU" which corresponds to the following UL file:
http://database.ul.com/cgi-bin/XYV/temp ... sequence=1
concerning the firm SHENZHEN XUNJIEXING CIRCUIT TECH CO LTD: could you then confirm that this is the producer of the compute module?
Last question. On the PCB compute module there is the silk screen "94V-0" below the code "RU E305654": could you confirm that the flammability class of PCB is V-0? "

Thank you

There are two manufacturer's of the boards depending upon whether you bought them from RS or Premier Farnell, the one you link to is the correct manufacturer for the PWB for the CM's manufactured in China

For those manufactured in the UK the UL data is: (Note you can find the specific code as MC1 on the boards)

http://database.ul.com/cgi-bin/XYV/temp ... sequence=1

Quite clearly from the UL data it is V-0

I still don´t understand why TS requires this information for CE certification. It´s all ELV stuff, no dangerous high voltage or high power here. V0 is a UL classification, totally not relevant for EU.

CE doesn't just apply to electrical parts of a product, but shows that all European products rules are being complied with. So if a RPI was embedded within a toy the CE mark would not only indicate the electrical safety aspects & radio interference aspects but also adherence to the Toy Safety Directive.

If one of the directives a particular product needs to obey includes fire safety or food safety then it is perfectly possible that sort of information might be needed...

Yes that might be so but TS specifically requests: "we would need information about the construction of the PCB’s compute module: the class of flammability, clearance, creepage distances, electrical insulation. "

Which are typically LVD related issues. Also, the questions are very non specific. Creepage and clearance are circuit related and so have no general value. At best the applicable standards define minimum values for those as design rules or guidelines.

Concerning the flammability, have you ever seen a glass fibre epoxy board that didn't have at least equal to UL94-V0 flammability rating? I mean one that burns like a candle :lol: When was the last time you checked the flammabiltiy rating of resistors, capacitors or IC packages? Why only consider de flammabiltiy of the board? I suspect a lot of UL rules are only here to generate a constant cash flow in the direction of UL. That's how the finance their institution.

Mm... I suspect a lot of rules are only here to generate a constant cash flow away from all of our pockets ;)
