Laptech’s Enclosures use brazes seal.

Press Release Summary:

Laptech’s Enclosures are available in SMP-8 and SMX variants and measure 8.0 x 7.2 x 2.3 mm dimensions. Units offer heat transfer through the metal and ceramic package and come with four mounting options. Products are suitable for satellite and data communication applications. SMP-8 offers temperature resistance up to 250 °C whereas SMX-8 provides temperature resistance up to 300°C.

Original Press Release:

SMP8 Precision Low Profile Crystals from LapTech

SMP-8 and SMX have a low profile smd enclosure in which precision SC cut, AT cut and IT cut crystals may be encapsulated. They utilizes a braze seal and are assembled in a vacuum resulting in higher Q values and therefore improved phase noise. SMP8 (8 ~ 130)MHz and SMX (6 ~ 220)MHz measures (8.0 x 7.2 x 2.3) mm and can be made with custom specifications.

They both have excellent heat transfer through the metal and ceramic package provides opportunities to improve thermal designs for OCXO. The SMP-8 and SMX with Four point mounting provides excellent shock and vibration performance with good immunity to G sensitivity.

SMP-8 and SMX crystals are mainly used in satellite and data communication applications. The SMX-8 has excellent thermal transfer properties and a low Q which can improve levels of thermal perturbations. Both devices are excellent for high temperature resistance the SMP-8 up to 250C and the SMX-8 up to 300C when ordered with the high temperature option.

Another feature both SM devices have is the option of adding a thermistor internally. This improves the accuracy and speed of the thermal feedback circuit when used in a TCXO. The option also may have advantages in OCXO applications. The chip thermistor and wire combination allow thermal measurement in very close proximity to the crystal itself.
