+## Building AIC Touch
+AIC Touch, another variant of AIC Pico, comes with an integrated touchscreen. However, its tiny FPC/FFC connector significantly increases the soldering and assembly difficulty.
+
+### Components
+* For the Raspberry Pi Pico, NFC module, 6x WS2812B 1204 LEDs and the R1 resistor part, follow the guide for AIC Key.
+* C1, C2, C3, 0603 0.1uF capacitors, they contribute to a more stable power supply.
+* R2, R3, pull-up resistors for the I2C bus, 0603 1Kohm ~ 4.7Kohm.
+* 1.69 inch 240x280 LCD touchscreen (ST7789 + CST816). Several vendors are making this model, as long as one has the exact same looking, it will be fine. It looks like this.

+
+### Assembly
+For most of the part, just follow the guide of AIC key.
+
+Soldering the 18P-0.5mm-1.0H FPC/FFC connector can be challenging. Here are some tips to make the process easier:
+* Use a small, sharp iron tip, the smaller the better.
+* Set your soldering iron to a lower temperature, below 280 degrees Celsius.
+* Apply a generous amount of high-quality solder flux to keep the pins "wet" during soldering.
+* Use thin low-temperature solder wire (for example, diameter of 0.3mm).
+* Start by soldering the mounting pins on both sides for proper alignment, then proceed with the 18 main pins.
+* Don't feed solder wire directly onto the main pins.
+* When soldering main pins, only apply a very small amount of solder to the iron tip.
+* If you apply too much solder, a solder wick can be used effectively to remove the excess.
+
+Remember to attach 1mm-thick soft pads to support the touchscreen. You can use 1mm 3M VHB double-sided tape, but do NOT remove the red film liner (don't let the tape stick to the touchscreen).

+* C1、C2、C3，0603 0.1uF 电容，它们有助于更稳定的电源供应。

+
+### 组装
+对于大部分内容，请参考 AIC Key 的制作。
+
+焊接 18P-0.5mm-1.0H FPC/FFC 连接器很有挑战。以下是一些提示：
+* 使用小而尖锐的烙铁头，越小越好。
+* 将你的焊接铁温度设定在较低的温度，大约 280 摄氏度。
+* 使用大量的高质量焊接助剂，以保持引脚在焊接过程中“湿润”。
+* 首先焊接两侧的固定引脚以确保正确的对齐，然后焊接 18 个主引脚。
+* 避免直接将焊锡丝喂到主引脚来焊接。
+* 在焊接主引脚时，只需要在烙铁尖上附着极少量的焊锡。
+* 如果你用了过多的焊锡，可以用吸锡带去除多余的焊锡。
+
+记得贴一层 1mm 厚度的软垫以支撑触摸屏。你可以用 1mm 厚度的 3M VHB 双面胶带，但是不要移除红色的保护层（绝对不要让胶带粘在触摸屏上）。
