CalrEC Putting Sound in the Picture 7
In order to comply with European RoHS
(Reduction of Hazardous Substances)
legislation, from the second week in April
2006 the vast majority of Calrec PCB and
cable assemblies will have been produced
with lead-free (tin/copper/silver) solder
instead of tin/lead solder.
This means that for a period of time
after April 2006 delivered consoles will
contain a mixture of assemblies produced
with different types of solder. This is
unavoidable due to the fact that circuit
boards are built in batches and allocated
to consoles on a ‘first in, first out’ basis
(hence the need to change the process
well in advance of the legislation coming
into force).
In the unlikely event of a user having
to carry out any re-soldering on such
assemblies, it is imperative that the correct
type of solder is used; not doing so is likely
to have an adverse effect on the long-term
reliability of the product.

Circuit boards assembled with lead-free
solder can be identified (in accordance
with IPC/JEDEC standards) by a small oval
sticker placed on the top-side of the circuit
board near the PCB reference number
(8xx-xxx).
The same sticker is used on the
connectors of soldered cable assemblies.
The absence of a sticker indicates that tin/
lead solder has been used. If in doubt,
please check with a Calrec customer
support engineer before carrying out
any form of re-soldering.
