I want to tell more about the process of solder paste printing. The reflow soldering process naturally contains more steps than the solder paste printing. Regarding the sensitivity to failures, the solder paste printing drives the entire job.
The fine component pitch requires "finer" solder paste types. The word finer means finer solder paste powder distribution. In other words, the solder paste particles are smaller and homogeneously distributed.
The solder paste temperature when printing must be your concern as well. Too-liquid solder paste does not keep its shape, while too-thick solder paste does not enter the stencil openings. The other trap is that the optimal temperature window for the solder paste printing is relatively narrow. It means you must cool down the paste after a few print runs....
Selecting Antenna Connector Types for RF Circuit Boards
I'm working on an RF circuit board design and I'm a bit stumped on which antenna connector type would be best suited for it. I need something compact yet efficient in terms of signal quality. Could you recommend some options and provide insights into their pros and cons?
Solution:
You can check here they have embedded antenna https://www.johansontechnology.com/antennas
What is Load Capacitance of A Crystal
When Designing circuits and while reading the datasheet of crystals, it usually talks about load Capacitance. Please help me to understand the function of load Capacitance and how it affects the oscillating circuit in my design. Usually it's rated in pico farads. What happens to the crystal if a load Capacitor is not added.
Solution:
load capacitors are not optional component; they are a fundamental part of the crystal oscillator design.
Zero Ohms resistor on the Power Line
Am designing a PCB Board, in the schematics section at the power line, I added a Zero ohms resistor to VBUS power rail for cleaner power. Is adding this value of resistor a good practice at the power rail of a design, is there any tendency of the circuit not functioning as required?
Solution:
I place 0R resistors not for the sake of cleaner power but for the sake of the ability to separate circuits when debugging. I believe this is the common motivation for many engineers.
Yes, it's a good practice to place 0R resistors into circuits. Especially:
โข At power supply inputs.
โข At power supply outputs....
How Do I use an Op AMP for Signal Amplification
Recently Studying about Op Amp and Its Operations, needed some guides from you guys on how i can effectively use Op AMP for Signal Amplification. What are the best Op Amp IC which is cost effective that can be used for Audio Amplification. Want to use it in my design so needed some Guide.
Solution:
Audio has its own series of op amp which is optimised for audio signal and it would not be a part of standard Opamps series. Audio Opamps and circuits are readily available in market, so I would recommend Opamps like NE5532 for first designs.
Rule of Thumb for Mouse Bites?
Creating a PCB that I envision as normally being attached, with a section that can be broken off and discarded in certain circumstances. At this point I'm just doing a V-score, which might be the correct solution, but if I wanted to do mouse bites do people generally have a footprint that they use (KiCad in my case)? Or is there a rule of thumb for drawing them in? Thx!
Should I have a Dedicated Power Plane on My PCB
During my last design I used a dedicated layer/plane for power. But during the design review the engineer asked me to remove the dedicated plane and just route the power around. And use that plane for ground. Wanted to know when is right or wrong to use a dedicated plane for power, need your insight on this. Thanks.
How to Reduce Crosstalk in a PCB Layout
If the space in a pcb board is fixed and there are limited number of routing space on the board, what can i do in order to reduce crosstalk, because the traces are tightly coupled which can lead to noise issues. In this case it is a High Speed Board.
Solution:
I recommend using a multi-layer PCB with the adjacent layer below the TOP layer made of a full solid ground reference plane. Plus, I would not recommend to use a copper pour on the top layer when using the inner layer reference plane.
