Northwest EMC

Complimentary EMC Seminar by TechDream at Northwest EMC’s Irvine Facility

November 8 2010

Tuesday, November 16, 2010
10:00 am – 3:00 pm
AT:
Northwest EMC
41 Tesla
Irvine, CA 92618

The seminar is designed to provide new information regarding, “Testing for EMC compliance: Mitigation Techniques” and “The latest EMC design solution for PCB above GHz.”

EMC design above GHz is more complex and difficult because resonance occurs when the wavelength is equal to the size of PCB or chassis and also the affect of stray capacitance and parasitic inductance increases. This lecture provides key EMC design tips for PCB above GHz and also EBG (Electromagnetic Band Gap) structures to reduce noise coupling in PCB.

This presentation will discuss techniques useful in performing EMI/EMC mitigation with some common solutions and implementation methods. Conducted and radiated emissions will be discussed. Conducted and radiated immunity/susceptibility techniques will also be discussed. Helpful methods to safely recreate immunity issues will be explored. A step-by-step procedure will be given.

Requirement changes for testing Information Technology Equipment- CNS 13438 Taiwan

October 29 2010

Attention manufacturers of ITE products; those with an existing Declaration of Conformity, must have them updated by March 1, 2011 in order to ensure compliance of your products.

As of October 1, 2010, manufacturers of ITE products must now meet two new requirements with regard to their EMC testing. The Bureau of Standards, Metrology and Inspection (BSMI), has begun implementing measurement of Radiated Disturbance above 1GHz and Conducted Disturbance at Telecommunication Ports in order to comply with CNS 13438.
The requirements before October 1, 2010 called for Radiated Disturbance below 1 GHz and Conducted Disturbance to the AC mains only. BSMI now requires implementation of two additional tests items as mentioned above, in order to fulfill the requirements of CNS 13438.

The above-mentioned testing items are applicable to products that have the internal emission sources utilizing highest frequency more than (including) 108MHz and / or telecommunication ports such as Information Technology Equipment (ITE), multimedia equipment and similar equipment that are tested to comply with CNS 13438.

BSMI will accept such applications complying with the above-mentioned testing items starting from the date of adoption of the notice. When the BSMI completes the review procedure and approves the application, a certificate will be issued and the applicable inspection standard column will be additionally stated “complete 2006 version.”

For those products that have been certified before the date of implementation, the certificates that are issued without implementation of the above-mentioned testing items will remain valid until the date of expiration, provided that the products, including the main model, are not modified. For products that the additional testing above 1GHz and/or conducted disturbance at telecommunication ports are required to be performed, the certificates may be used until the expiry date and the certificate holders may not apply for extension of validity of that certificate. For products to which the additional testing above 1GHz and conducted disturbance at telecommunication ports are not applicable, the certificate holders may apply for extension of validity of the certificate.

For product certificates that are issued without implementation of the above-mentioned testing items, application for adding series models are acceptable before the date of implementation. Such certificates may be used until the expiry date and the certificate holders may not apply for extension of validity of that certificate. If the main model and series models of a certificate are tested and comply with the above-mentioned testing items, the certificate holder may apply for a new certificate. The term of validity of the new certificate will be 3 years and the applicable 2 inspection standard column will be additionally stated “complete 2006 version.”

When applying for adding series models that intend to comply with the above-mentioned testing items, all the existing main model and series models of the certificate shall be tested and comply with the same requirements. A new certificate will be issued at the same time for such applications.

Starting from the date of implementation, for products to which the above-mentioned testing items are applicable and the applicable inspection scheme is Declaration of Conformity, the obligatory inspection applicant shall have their products tested to comply with the complete test requirements, and re-declare the conformity (re-issue the declaration of conformity) according to the relevant regulations before putting the product onto the market.

VCCI pushes back their implementation date for Radiated Emissions above 1GHz

January 11 2010

December 14, 2009

VCCI Council will start enforcement of radiated emissions above 1GHz beginning October 1, 2010. However, for one year until September 2011 it will be optional to conform with the above 1GHz requirements. Nevertheless, the VCCI encourages members to ship products conforming to the 1GHz+ requirement beginning October 1, 2010 as if there were no 1-year grace period.

Reasons for 1-year grace period:
VCCI gave the following reasons for the 1-year grace period:

• EU Official Journal issued on August 21, 2009 says that the valid period of EN55022:1998, European equivalence of CISPR22 Edition 3, is extended to September 30, 2011. With this extension manufactures can select either CISPR22 Edition 3 or Edition 5 for product conformity until September 30, 2011.
• Similarly US FCC has announced that conformity assessment test can be based either on ANSI C63.4-2009 or ANSI C63.4-2003
• Under such circumstances it is necessary for VCCI Council to establish the 1-year grace period for avoidance of creating potential technical barrier to trade against overseas product to be distributed in Japan and, at the same time, for affording Japanese manufacturers flexibility in choice of marketable products in the grace period.

VCCI notice

September 4 2009

VCCI recently set their members the following notice:

Dear VCCI members –
This is to remind you that the following previous notice given in V-3/2009.04 Technical Requirements will actually be enforced as stated.

“Enforcement of limits of conducted disturbance at the telecommunication ports is from 1st April 2010, and enforcement of EMI measurement above 1GHz is from 1st October 2010.”

Let us elaborate on this statement as follows to avoid any misunderstanding on your part. Note that “telecommunication ports” and “above 1GHz” are referred to as “category” in the explanation.

What is meant by this statement is that you are required to measure your ITE against the given limit for conformity verification report to be filed to VCCI on and after, not before, the given date per category. Also the limit will be inapplicable to products already filed to VCCI and distributed in the market before the enforcement date per category.
