Fingerprint Sensor AS608 - A Beginner's Guide
One touch can replace keys. This project uses an optical fingerprint sensor to enroll users and then grant access with a quick scan.
read tutorial →A 100g spool of 0.8mm tin-lead solder with a rosin flux core. The 63/37 alloy is eutectic: it goes from solid to liquid at 183°C with no mushy in-between stage, which means fewer cold joints than 60/40.
| Alloy | 63/37 tin-lead |
| Diameter | 0.8mm |
| Weight | 100g |
| Core | Rosin flux |
| Flux content | 1.8-2.2% |
| Melting point | 183°C |
0.8mm is the all-rounder size: fine enough for headers and pads, thick enough for wires and connectors.
