Green Environmental Program

Title

Introduction

    Keltron is embarking on a program to phase in lead free components and process for its products. This is in line with Keltron’s Green Environmental Program and also in response to international

    legal developments (including but not limited to the European Union’s WEEE and RoHS

    directives) that will act to restrict the use of lead (Pb) in electronic components, assemblies and other related components. To begin on the lead free journey, Keltron will collect all the information on lead free and manufacture in lead free process, technology, material that are in existence or being developed in the market.

Scope

    Keltron can supply electronic components, connectors, headers, sockets and cables on lead free or stEnvironment-related Substances to be controlled on Jul 1 2005.

Expectations from Keltron

    ; We will provide customer a milestone chart or plan on how it intends to meet the

    timelines of the proposed legislative requirements for lead free.

    ; We will provide upfront information and regular updates on any cost impact of the parts

    due to lead-free conversion. Our supplier must work with Keltron to minimize the impact

    of such a conversion on cost and manufacturing during any transition periods.

    ; We will identify issues relating to quality, yield or long term reliability as early as

    possible and update our customer on those information.

    ; Lead free solder alloys and soldering processes are likely to result in higher assembly

    temperatures. We will develop components and product that are both lead free and can

    withstand these higher assembly temperatures. Note : plastic materials used in these

    components must also comply with the halogen free requirements of the new RoHS

    legislation.

    ; We will provide a product identification/part numbering plan to indicate which kind of

    metal alloy is used on a product in order to facilitate rework, repair and recycling and to

    reduce the likelihood of errors.

1. Acceptable substitutes for finishes containing lead (Pb)

    Acceptable substitutes for lead finishes on electrical components, heat sinks and printed

    circuit boards may include but are not limited to:

    1. Fused tin (Sn) with or without nickel (Ni) under plate

    2. Tin (Sn) over nickel (Ni) underplate-one microns minimum thickness of nickel (Ni)

    is required. Less than one Micron Nickel (Ni) thickness requires Neltron approval.

    3. Matte Tin (Sn) finishes with out a nickel underplate must meet the following

    requirements. : (note : annealing is not required with a nickel (Ni) underplate.)

    1) Matte Tin (Sn) finishes must meet the plating thickness greater than10 microns.

    2) The finish must undergo an annealing process at a temperature of 130 degrees

    Celsius or higher for a minimum of one hour.

    3) The heat treatment must occur with in two weeks of plating.

    4. Tin-bismuth (SnBi) component finishes are only acceptable with specific Neltron

    approval.

    5. Noble metal plating is acceptable without pre approval except for silver (Ag).

    6. Silver (Ag) plating Require Neltron Pre-Approval.

    2. Unacceptable Substitutes for Finishes Containing Lead (Pb)

     Unacceptable substitutes for lead (Pb) include but may not be limited to:

    2. Pure Tin (Sn), Matte or Bright, without under plate(unless by specific Neltron

    approval) except for the matte tin finish with subsequent annealing process as

    referenced in section1 above.

    3. Criteria to Distinguish Between Pure Matte and Bright Tin

    Supplier will establish a system to measure and to control characteristics of the tin plating

    known or suspected to influence whisker growth. Neltron requires carbon content 0.005%
