Information labeling system (ILS) for lead-free printed wiring boards
Global standardisation of soldering materials is not to be expected within the next years. This was learnt during the discussions with the inter-regional partners. A variety of materials will thus substitute tin-lead.
Repairs require solder that are compatible with the soldering materials on the board. In recycling, lead-free solders and platings on PWBs enable material specific treatment to increase profit and material recovery.
An information labeling system (ILS) about soldering materials can solve these problems. It should at least store information about soldering materials used in manufacturing of the PWB.
Minimum of information will be given byhelp of the e1, e2, e3- marking, proposed by the HPUG (See paper from Vivek Gupta in Brussels in Juni 03). But it seems to be not enough for the legal requirements comming with the WEEE/RoHS.
Stored information to differentiate appliances categories and features characterised in the WEEE contributes to implementation of WEEE, e. g. to decide between old appliances and old-old appliances that are subject to different treatment rules.
The ILS can also give feedback from repair and recycling about failures of certain soldering material combinations. Thus, an ILS facilitates statistic reliability investigations for manufacturers (tracebility), or gives information about thermal stress which influences remaining life time of components for reuse.
Please help us to work out the usefull ILS, answering the questionnaire in the left and send it back to Irina Stobbe and Budianto Liong
