• New combined website for RFX & Laptech Precision Inc

    Laptech Precision, established in 1972 and acquired by RFX in 2010 has until now maintained its own independent website. But we now feel the time is right to combine both businesses under the one RFX Group domain covering our full range of high-performance quartz crystals, VCXOs, TCXOs, OCXOs & GPS synchronised modules. We hope you like it!

    Ageing and Precision Crystal Oscillators

    Often when purchasing a precision oscillator such as an Oven Controlled Crystal Oscillator (OCXO), the phrase ‘after 30 days continuous ageing’ will be present. This phrase is a catch-all to allow for green age on a crystal within the crystal oscillator in which it is employed. Does this mean that specifications are guaranteed after thirty days continuous ageing? Surprisingly, the answer is both yes and no. If the oscillator is powered continuously and is not powered down after the thirty days, then generally the answer is yes.  If, however, the oscillator is powered down, even after a continuous thirty days of ageing, the answer is no...

    Crystals For Wildlife Tags and General Tracking

    An under the radar application for quartz crystals is transmitter tags used for the tracking of both humans such as medical patients that require lifesaving location monitoring and wildlife including insects, reptiles, mammals, birds and fish. Rapidly developing technology has completely transformed the capability of wildlife researchers and scientists to track animals of almost any size, in almost any environment. Whether an animal moves through a terrestrial, freshwater, marine or avian habitat, specialist manufacturers are now able to provide systems to track them using satellite, radio, acoustic, and archival monitoring solutions. Technology leaders in this field include companies such as ...

    Frequency Accuracy, Do We Really Need It?

    Precision crystal oscillators, typically high-performance temperature compensated (TCXOs) and oven stabilised crystal oscillators (OCXOs), are required to give accurate timing where the use of an atomic scale clock is not feasible. Accurate time information has been a constant requirement throughout human evolution. Perhaps the most recognisable of the solutions accurate time measurement has made in the past is with the solution to longitudinal position. In the seventeen hundreds it had been well known for centuries that your position in latitude could be determined by measuring the apparent distance between the sun at noon and the horizon with reference to a table of declinations. Or if the night was clear certain stars and the horizon. What was not measurable with any degree of certainty was your position longitudinally...

Experienced Lapping and Polishing services

Laptech Precision has many years’ experience in the lapping and polishing of quartz substrates. In addition to this we regularly lap and polish other materials including plastics and metals. Items include valves seats, actuators, gears, waveguides, supports etc. For single side lapping our 24” Lapmaster can accommodate parts up to 230mm diameter.

We also offer double side lapping and polishing which has some advantages in obtaining parallelism within a few microns.  We have three sizes of 4-way lapping and polishing machines, models 3b, 6b and 9b. These can accommodate diameters up to 150mm and finishes from precisely controlled matt surfaces up to full optical polish. 4-way lapping machines feature contra-rotating top and bottom plates that reduce drag on the piece parts. This reduces stresses on the carrier teeth and thus allows thinner parts to be processed.
