PTFE vs. Non-PTFE #RFPCB laminates Selecting the right material, whether PTFE or nonPTFE, is crucial for your RF designs. This choice significantly affects signal loss, dimensional stability, and board reliability. It's not just a simple decision; it depends on the specific needs of your applications. PTFE  and ceramic-filled PTFE laminates offer superior electrical performance and are preferred for radio-frequency applications. On the other hand, non-PTFE materials strike a balance between high-speed signal transmission and hassle-free fabrication. -- Read the article for a quick comparison among non-PTFE, PTFE, and ceramic-filled PTFE materials. -- Send this to RF engineers and PCB designers. #rfpcbdesign #highfrequencypcb #productdesign

8 best #electronic circuit design practices to kick off the week! 1. Define specification and build block diagrams. Develop a detailed specification that covers all aspects of circuit design including input, and output signals. 2. Employ pull up, pull down, and zero resistors. This will avoid the odd effects of your circuits floating state. 0-ohm resistors can be used to modify the circuit even after its instruction. These resistors are used as a bridge to route tracks optimally on a board. 3. Utilize microcontrollers and mix signal circuits to increase performance efficiency. These devices can be programmed according to your requirements. They also reduce the number of discrete components. 4. Reduce power consumption using PWM signals. Use PWM signal with a 75-percent duty cycle to reduce the mean output power consumption. 5. Implement safety measures for ESD, reverse polarity, transients, and over voltages. Incorporate voltage limiters, power diodes, fly back diodes, class X and class Y capacitors to reduce the risk of electro static discharge, reverse polarity, transients, and over voltages. 6. Select the components based on life cycle, ensure that you use parts that won't become obsolete and remain available for the next five to seven years. 7. Effectively capture the schematic and verify using EDA tools. Choose an efficient layout design tool, like Allegro or KiCad, that provides adequate design support. 8. Carry out simulations and functional tests to verify your design's functionality using a simulator. You can make necessary changes in case the circuit doesn't function as per requirements. https://lnkd.in/dAbyfDSE #pcb #pcbdesign #electronics #manufacturing

How to pick #RF PCB materials: 6 important factors to consider When designing RF PCBs, selecting the suitable material is pivotal for achieving optimal board performance. The properties of the RF laminates directly impact signal integrity, thermal management, impedance uniformity, dimensional stability, and manufacturing efficiency. Article highlights: When designing radio-frequency boards: 1. Choose laminates with a low dielectric constant (<4) and low dissipation factor (<0.005). 2. Select materials with similar CTEs to prevent warping and improve reliability. 3. Opt for high thermal conductivity materials for effective heat dissipation. 4. Use low-profile copper foils to reduce signal losses. -- Read the article to learn how to choose the right dielectric material for your RF prototypes. -- Send this to post to PCB designers and engineers. #rfengineering #rfdesign #highfrequencypcb #electricalengineering

We're told it's #InternationalFashionDay...

#Decouplingcapacitors reduce undesired signal interference in #PCB designs and provide a stable power supply to ICs. By isolating sensitive signals, these capacitors mitigate voltage fluctuations caused by transient currents and prevent circuit malfunction. #Simulation tools offer invaluable support by enabling design verification, debugging, and “what-if” analysis. This proactive approach helps you identify and address potential issues before physical boards are manufactured, significantly reducing design cycles and minimizing costs. In this webinar, you will learn the best strategies for placing decaps to avoid parasitic oscillations and #EM radiation in your layout.
