Webitself protects the underlying Cu conductor/connector. Common HASL material include SnPb, SnCu or even SnAgCu alloys. The thickness of an HASL finish can vary from 0.2 to 50 um. One of the best features of HASL is that it readily solders. After all, the Sn based alloy is the same material used in soldering which allows for a good joint. WebSelection of Thin & Thick Plates With HASL, board thickness can reach up to two hundred miles. However, since the procedure relies on onboard technology, it may cause slower electric conductions in certain cases. ENIG’s plate is a favorable electrical connector due to its minimum gold thickness of five to fifteen inches, making it easy to solder.
WebHere are the recommended minimum and maximum thickness values: 17.8 μin is recommended for IPC maximum solderable thickness 25 μin gold over 100 μin nickel for IPC Class 1 & Class 2 applications 50 μin gold over 100 μin nickel for IPC Class 3 applications Soft Gold Surface Finish http://www.58pcba.com/index.php?id=1080
WebHASL has board thickness up to 200 mils. Because the process is dependent on the board technology, plates may be slower during electric conductions.
