PCB IC card (tested)

Overview

PCB card, you can freely modify the picture. Use PCB as the coil and thicken the coil. There is a ruler on the PCB to facilitate measuring the length. You only need a 13.5MHz IC card chip to weld. There is nothing to introduce. No LED is added. lamp, to ensure maximum stability and facilitate welding.
This project has been tested, and there have been no problems so far.
Suggestions:
1. It is recommended to use low-temperature solder paste and weld with the heating table. The chip must be clamped during welding, otherwise the chip will One solder joint runs
2. If you use a lighter to heat from the back, you need to control the time. Failure to control the temperature may burn the chip.
3. There is nothing to say ←_← This is also relatively simple. Generally, lead-free solder paste can be used for soldering. If the solder joint is not perfect, you can heat it again and the solder joint will be full and round.

Is the 40TPS12A thyristor in this power-on buffer circuit used to switch the resistor?
What is the specific working principle? Why does one of the two power-on buffer circuits use so many filter capacitors, while the other only has one? Aren't the bus voltages the same after rectificati

Question F: Output impedance is 600 ohms???
[i=s] This post was last edited by paulhyde on 2014-9-15 08:57 [/i] I would like to ask the engineer, how to achieve the output impedance of 600 ohms of the preamplifier in question F? Do I need to us
Why can't the CC2530 timer interrupt flag be cleared?
Why can't the CC2530 timer interrupt flag be cleared? The effect is there, but the interrupt flag cannot be cleared. The code is as follows. [code]#include void InitT3() { T3CTL |= 0x08 ; //Open overf
The resistance and capacitance values in the filter
I see that many resistor and capacitor values in filters are accurate to decimal points, but I don't understand: 1. Do they have to be so accurate? How can they be achieved? 2. If not, how can the err
