As a small manufacturer based in the UK we have also had our fair share of the CE problems, this situation was not helped because we make transmitters and receivers and electronic equipment under the CE directive are not supposed to interfere with each other which is exactly what a transmitter and receiver are supposed to do?. This caused some confusion for a while
Our manufacturing has now been moved over to lead free although many types
of equipment (Telecom equipment and safety based) are exempt because of the tin "whisker problem mentioned earlier. Our sub contractor seems to have the lead free soldering cracked now but we have had to go over to gold plated PCBs to get a better finish.
We have stocks of finished items eg. Pocket Pager receivers these were bought in as complete units and are not lead free, we can sell these units into the market because they are existing stock, I dont know if the Castle mother board would be covered in this way as it is a component rather than a finished item?.
