For Communications Equipment
Combining crystal and oscillator circuitry defends market share

SaRonix B.V. is a medium-sized Dutch company designing and
manufacturing quartz crystals and oscillators for the general & industrial
market, with sales of 20 MECU. The 200 persons work force includes some
15 professional electronic engineers (B.Sc. to Ph.D. level). The product
line includes quartz crystals in metal or glass encapsulation; and a variety
of quartz oscillators in metal encapsulation: clock oscillators; voltage-controlled
oscillators; temperature-compensated oscillators; and combined temperature-compensated
voltage-controlled oscillators. The product frequency ranges from 1 to
The objective of the AE was to reduce the size of the quartz oscillator
to an absolute minimum by incorporating the quartz blank and an oscillator
IC die into a common, hermetic encapsulation in which the interconnection
is integrated, i.e. a ceramic chip carrier with sealed lid.
The existing oscillators of SaRonix are built on PCB-type or hybrid carriers.
They are large because of their through-hole leaded metal package, in
connection with the hermetic sealing requirement of the quartz. They are
expected to lose market share because most new applications capitalise
on the concept of miniaturisation, e.g. mobile telephony, PCMCIA cards.
With the new adapted technology the through-hole version changes into
true SMD; the SMD connections are integrated into the carrier; the carrier
can be sealed hermetically without the need to seal the quartz in its
own, separate housing. The size of the resulting product is only determined
by the quartz itself. In addition, the cost price is reduced considerably
because of fewer materials.
The economic benefits of this AE are a strong increase of sales quantity
and profits. The capability of SaRonix increases with the design knowledge
in a new, MCM technology and the option to apply this in manufacturing.
This AE had a duration of 13 months. The whole project, including the
investment in production machinery, cost 1250 kECU, of which 143 kECU
was related directly to this AE. The payback period of the whole project
is expected to be less then 18 months. Total return over an estimated
life cycle of 10 years is estimated at 4.3 M ECU. The ROI is 344%. or
34.4% per annum.
The project has successfully been completed. SaRonix learned the design
rules for ceramic chip carriers; how to implement a sensitive quartz crystal
into this carrier; critical design parameters for the interaction of IC
and quartz in an integrated small housing; critical process parameters
for maintaining product quality. The experience is such that a manufacturing
line could be installed.
