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. +* The touchscreen will block PN532's RF signal so we need to offload the antenna to AIC Touch's PCB just like what we do in PN5180 version. + * To build PN5180 version, short the "PN532 ANT" (green mark in the picture).
