For
the production of lead-free electronics you need unleaded
solder, as well as lead-free components and circuit boards.
Furthermore, unleaded solder requires a different kind of
soldering procedure than conventional ones. The major difference
lies in the need for higher remelting temperatures, approx.
230 °C, which also means a narrower process window, consequently
avoiding unnecessary strain on components.
We
have installed a VaporPhase machine for vapour phase soldering,
and for the last two years or so we have always made sure
of purchasing lead-free components where available. Lead-free
components are always highlighted in our MPS system. The
components not yet available as lead-free, but which have
been given a date for lead-free introduction, are also registered.
Today,
not all components are available as lead-free. Furthermore,
it is not always possible to receive precise information
from distributors and manufacturers regarding when and,
in certain cases, if components will be available as lead-free.
We
do undertake the task of producing a preliminary inquiry
with regards to components, to assure lead-free customer
circuit cards and to identify components by the following
criteria:
- Lead-free component today
- Will be available as lead-free from (date)
- Not available, i.e. no information available from distributor/manufacturer
- Will not be available as lead-free
This
identification process provides the customer with enough
information for a decision on how to proceed, e.g. the need
for product reconstruction or cancellation.
The
identification, as described above, is an on-the-spot account.
Our lead-free component supply is improving on a daily basis.
