Hi Richard - Can you provide any information on what type of use environments the Pwbs are going into? Even something generic would be helpful to those of us looking at the Alphalevel.

Our decision to install was based on the following: 1. We wanted a finish suitable for all pcb types. 2. We wanted to do something about the safety and environmental concerns of our old vertical Quicksilver machine. 3. We wanted to automate the labour intensive HASL process of our vertical machine. We are very pleased with the performance of the process. We are now processing 60% of our production using AlphaLevel. All our customer approvals have been on the understanding that they do not want to change their wave solder parameters. This is understandable when they are buying from a number of sources that give HASL, Ni/Au etc. During installation we experienced some problems concerning the control of the deposit. It has not been easy to develop a QA test that effectively assesses how the process will perform on different customers' assembly lines. Understanding how the process parameters effect the thickness of silver and the thickness of the organic layer has been quite absorbing! The cosmetic appearance is very good. The finish "looks solderable" and does not give the initial suspicion and worry that new users have with organic coatings over bare copper. I can not be specific on costs. However, it is exceedingly competitive against the Ni/Au alternative. Richard Wood-Roe Artetch Circuits Ltd.
