Measuring and test-tools, various prototypes from a single unit volume, create a PCB and its manufacturing data
Flexible
The hardware design process must be flexible. Not all requirements are always known from day zero. The changes are necessary, and I always keep in mind plans B or even C.
Simply
I focus on the simplicity of each design. A strong focus is always on removing complexity and keeping the necessary parts. The result is higher reliability and a longer product lifetime.
Modern
A part of my time is dedicated to the market observation. All renowned silicon manufacturers present their new products frequently and I focus on keeping touch with them. I like to learn new things and it is one of my
My life
My life. I wake up at 5:00 AM. Monday to Sunday. I study foreign languages between 6:00 AM and 7:00 AM. I start working slightly after 7:00 AM. I work until 4:00 PM or so. I fill my life with...

Manufacturing
Manufacturing In the picture, there is almost everything. 1️⃣ Digital microscope for optical checks 2️⃣ „Moonlight“ for workplace enlightenment 3️⃣ DMMs and other instruments Yes, there are missing soldering iron and other tools. For some reason, they did not fit...

TS-3032-C7
I presented my TS-3032-C7 temperature sensor demo on the CR2032-powered dongle. The PCB accommodates only a few components—with a focus on the lowest price possible. The first step was to capture the simplest schematic and create a layout for the...

Manufacturing?
Is it still MANUFACTURING? Today, I am almost afraid to call my job manufacturing. 1️⃣ I didn’t even order a stencil. 2️⃣ I squeezed a solder paste caterpillar directly from the syringe. 3️⃣ I didn’t even use the oven. I...

Clearance/Creepage
🚫 Clearance isn’t creepage These two terms can be confusing, and they are. We need to remember that the shorter distance is the air distance = creepage. while the longer, the surface distance, is creepage. Just when we want to...

Keep your tools updated
I was unable to connect to the new prototype board MCU because I didn’t keep the App updated. It sounds like a nonsense but it’s not. The new microcontrollers are comming quickly and I failed keeping track with them. The...

Stencil printing
Stencil printing always tops the naive and primitive techniques There is no doubt and no discussion about that. The quality of the printed solder paste layer is always better. I don’t want to be known as the guy who squeezes...

Understanding basic S-parameters
➡️↩️［ DUT ］⬅️ 𝐖𝐡𝐚𝐭 𝐚𝐫𝐞 𝐒-𝐩𝐚𝐫𝐚𝐦𝐞𝐭𝐞𝐫𝐬? 1️⃣ Scattering or shortly 𝐒-𝐩𝐚𝐫𝐚𝐦𝐞𝐭𝐞𝐫𝐬 are defined as the ratio of the outgoing wave to the incoming wave at a port of a network. 2️⃣ 𝐒-𝐩𝐚𝐫𝐚𝐦𝐞𝐭𝐞𝐫𝐬 are typically measured using a network analyzer (VNA)....
