No Hassle LEAD-FREE HASL

摘要

As the July 2006 Restrictions on Hazardous Substances (RoHS) deadline looms, PCB fabricators and even designers continue to search for information on lead-free processes. Many PCB shops are preparing to convert to alternative surface finishes (or at least add the capability). But, despite all the ink that's been spilled - and hot air expounded - on the subject of alternative surface finishes, there seem to be more questions than answers. There are numerous alternative surface finishes available, and all have their supporters and detractors. One of these, lead-free hot-air solder leveling (LFH) has shown success in lead-free manufacturing. This Q&A session should help provide some clarity on LFH - what it is, what it isn't and how it works.
