If you need any info about the 4785, let me know. If you understand Perl I'd be happy to send you the software I wrote for 4785 program generation. Mine is based around PanaPRO but it would at least give you a very simple optimization routine if

Hi, Does anyone know where to purchase the connectors? Specifically bulkhead connectors or PCB mount connectors. I am thinking about doing a general purpose SMEMA box that has a Basic Stamp in the core, and some buttons so I can use it for general

Yes, it can evaporate. My point was manufacturers suggest cool storage to avoid seperation. I guess if the flux does seperate and get pushed to the top it could have a greater chance to evaporate. I have only seen such seperation on year + old jar

Contractor mantra: * Profile is good * Boards are bad On profiles, the key question is: where did you take the profile? We�d guess cracked connections are giving the intermittent test results when pressing on the components. You use acoustic micro
