Children's Day update! I was happy to get the board today. As expected, the screen printing text effect is not particularly good. The area is small and there are many texts. It is recommended not to change the area of the board to a small size. Furthermore, Jialichuang cannot screen print directly on the fiberglass board? For example, add a top layer of solder mask first, and then add silk screen on top? When I placed the order, I chose the thickness of 0.8, which is easier to bend and deform. If you want to apply patches, you can choose 1.0.
The following is the subway card moving process
. 1. Find a good subway card and find the nfc chip.
2. Use physical methods to get the chip out. Here, you first cut it with scissors and then burn it with a lighter
. 3. Weld the chip to the pcb.
over! Family photo, 2 tags, 1 subway card
0716 update! I took the subway a few days ago and found that the subway machine could not recognize the card and could not recharge it. As for the turnstile, it should be able to identify it? What is certain is that buses can be used normally. It should be a problem with the coil inductance. If you need to use a counter to recharge, please pay attention to this and check the specifications of their coils. You can currently recharge using your mobile phone. The counter machine cannot be recharged!
