Header Long-Term Aging of Quartz Crystals

Each application has a tolerance budget in terms of frequency deviation that must be adhered to even in the worst case scenario in order to ensure that the application functions. Developers must therefore be aware of all factors that can lead to frequency deviations. The sum of all worst-case scenarios of these factors must not

Header 3D-Drucker

A new machine is improving our sample and prototype construction in Villingen-Schwenningen – although calling it a ‘machine’ may be stretching it 😊. Instead, what we have is a 3D printer, which brings a number of advantages: both our customers and our own in-house staff now benefit from greater speed and flexibility when it comes

Header: Ein Batteriepack für XSPECTER

Founded in October – and on the market within just six months: Start-up XSPECTER has its T-CROW XRII to thank for this success. The product behind this futuristic name is a special tripod for thermal imaging and night vision cameras. The product: A controllable 3D-printed camera tripod The T-CROW XRII is a controllable camera tripod

Battery Safety – The CE Mark

In the development of battery packs, the focus is often only on technical development. However, this alone does not go far enough. After all, new batteries require various certifications so that they can be placed on the market in compliance with the law. Worldwide, there is a multitude of different rules and regulations concerning the

In the blog posts Ask the Product Manager: Are real rock crystals used for production of oscillating quartz crystals? and Quartz production process: from quartz block to quartz blank, we have already taken a closer look at the first stages in quartz production, what material the quartz blanks are made of and what steps are

header IEC certification

The standards of the International Electrotechnical Commission (IEC) are among the most important groups of standards for the certification and safety of electronic products. They include both cells and batteries and span primary cells, secondary cells, battery packs and portable device batteries. In addition to the requirements for the devices and central rules for the

Header "UL certifications - the key to the US market"

For market access in the USA, a so-called NRTL test mark is required for many products. As NRTL does not have its own test mark, test laboratories are accredited accordingly and their test marks are then recognised as NRTL test marks. The most important test mark on the US market comes from Underwriter Laboratories (UL).

The previous blog post entitled: Ask the Product Manager: Are real rock crystals used for production of oscillating quartz crystals? covered the initial stages in the production of these small clocks. Quartz is artificially grown in autoclaves, reaching a weight of several kilos. From this point, however, we are still a few production stages away

Header UN 38.3 test

There are various certifications that are relevant when dealing with batteries. On the one hand, this includes the UN38.3 transport test, which concerns the transport safety of lithium batteries. This test is a must as soon as batteries are shipped. On the other hand, there are certifications that, although not mandatory, confirm the safety of

SiO2 – this is the chemical name of the base material for oscillating quartz crystals. The formula shows that it is composed of only two elements: silicon and oxygen. We also find SiO2 in its crystalline form in the nature: as natural rock crystals. Here, the question arises: Are real rock crystals used for production
