Ask the Product Management: Are real rock crystals used for production of oscillating quartz crystals?
Thursday, 31 March 2022
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

Insights into the daily tasks of a project manager: The first steps in battery development projects
Tuesday, 01 March 2022
In the consumer sector, the decision for the right battery is made quickly. There are standard batteries which fit in consumer applications. However, in the industrial or medical technology sector, the situation is different. For these applications, “off-the-shelf” batteries are often not suitable. There are special requirements concerning safety or space. The solution: individually developed

Miniaturisation of components: what to pay attention for with quartz crystals
Thursday, 27 January 2022
The topic of component shortage is omnipresent. Nowadays, almost every electronic component is affected. The reasons? There are various of them and they include supply problems, as well as, correspondingly, the availability of the components. Others can be traced back to digitization, resulting in an increased number of final products and, due to this, a

Ask the Engineer: how temperature-sensitive are quartz crystals?
Tuesday, 07 December 2021
Nowadays, Christmas without quartz crystals is unimaginable! Why? Even the modern time switches for outdoor lighting need a quartz to have an accurate time base. Also, a lot of our gifts are based on state-of-the-art electronics. Cell phones, smartwatches, PCs – they all need highly accurate frequency giving components to communicate with each other. Without

What is the difference between a Protection Circuit Module (PCM) and a Battery Management System (BMS)?
Tuesday, 16 November 2021
When developing battery packs, the question arises as to which safety system the pack should be equipped with. Is a Protection Circuit Module (PCM) sufficient? Or should a Battery Management System (BMS) be integrated? What are the differences between the mechanisms? And what advantages and functions does which protection mechanism offer? The answer here, as

What is the similarity between a quartz blank and a pillow?
Thursday, 28 October 2021
Do you already know the similarity between a quartz blank and a pillow? Exactly! Both have the same shape. The so-called “bevelling” or “contouring” in the production process of quartz blanks results in the characteristic lens shape of quartz blanks. “This procedure is mainly used for ‘thicker’ blanks, which are in the low frequency range,

What actually happens when lithium batteries are over-charged or deep discharged?
Thursday, 14 October 2021
Charging Process: Lithium-batteries are charged with constant current until a voltage of 4.2 V is reached at the cells. Next, the voltage is kept constant, and charging continues for a certain time. The charger then switches off further charging either after a preset time or when a minimum current is reached. In the rare event

Why does a quartz crystal have to be hermetically sealed?
Monday, 06 September 2021
What you always wanted to know about quartz crystals, but didn’t dare ask until now … – Why does a quartz crystal have to be hermetically sealed? At the end of the complex production of a quartz, or rather the small quartz disc, the quartz blank, it has to be mounted in a housing that

What special features are there to consider when designing-in a lithium polymer cell?
Thursday, 02 September 2021
What special features are there to consider when designing-in a lithium polymer cell? An important point, according to battery expert Dr JĂĽrgen Heydecke, is certainly the so-called “swelling”, the natural swelling of a lithium polymer cell in a fully charged state and over cycles. A fully charged cell is thicker than a discharged one. During
