Use of Lead-Free HAL/HASL as surface finish on PCBs increases

Jan 16, 2006 · Use of Lead-Free HAL/HASL as surface finish on PCBs increases To choose surface finish for your PCBs when we are entering the Lead-Free era is not allways that easy. There are a number of surfce finishes to choose between.Why Is Lead Free HASL Finish A Hassle?Hot Air Solder Leveling (HASL) has always been the main staple of PCB surface finishes. In the late 1980s, 60/40 tin-lead reflow started to phase out of processes and was replaced with Hot Air Solder Leveling. HASL finish, the long running reliable surface finish, is still used today in military, aerospace, medical, and other applications.
