Measuring and test-tools, various prototypes from a single unit volume, create a PCB and its manufacturing data
The hardware review will cover everything from schematic, footprints, signal interconnection, signal and power integrity, to rules for a successful EMC.
I have solutions! Your design will be checked and all point of your concern will be analysed. My own points will be highligthed and discussed. Your issues + my review = leap-frog into a successful design
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
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
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 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
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 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
➡️↩️［ 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).
🆕 𝐏𝐈𝐓𝐀𝐘𝐀 𝐛𝐨𝐚𝐫𝐝 𝐕𝟎𝟔 𝐢𝐬 𝐛𝐨𝐫𝐧! Yesterday, I wrote about the DAC11001 board in its 6th revision. In version 05, I moved mounting hole positions on this board. I didn’t have a chance to synchronise both designs until this revision
🆕 𝐈 𝐚𝐦 𝐰𝐨𝐫𝐤𝐢𝐧𝐠 𝐨𝐧 𝐭𝐡𝐞 𝟔𝐭𝐡 𝐫𝐞𝐯𝐢𝐬𝐢𝐨𝐧 𝐨𝐟 𝐭𝐡𝐞 𝐃𝐀𝐂𝟏𝟏𝟎𝟎𝟏. Why on Earth do I need another revision? Well, because I moved mounting hole positions on a mating board and did not have a chance to synchronise both designs.
🎩🎩🎩 Don’t try to unsolder the entire connector! Here is a tip for all who need to unsolder the multi-pin connector from the boards. First thing first… ❗️ The value of the assembled PCB is much higher than the cost
