This week we had to do some reworking of an ESP32 module that has pads underneath. When this happens, we have to apply paste using a syringe to the pads and then heat up the PCB and module together with a hot-plate or hot-air machine. Solder paste syringes are super handy to have and have a long shelf life. Let's look at some options on Digi-Key and which ones you'd pick based on your rework or solder needs!See the chosen paste on https://www.digikey.com/short/8v23v17zVisit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordAdafruit on Instagram: https://www.instagram.com/adafruitSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#adafruit #thegreatsearch #digikey @Digi-Key
