| | | we've received an inquiry if lead free solder for solder dips or surface mounting (cream solder) is available on a technical scale | Dr. Weber I'm not sure what you mean by "on a technical scale" but various no lead alloys are available in

the copper forms intermetallics with tin to get Cu3Sn and Cu6Sn5. thus intermetallics formation consumes Cu and depends upon the cooling rate, faster the cooling rate, lesser the intermetallic formation

Hello Arnold, Yes, by definition of joint formation, copper will dissolve in lead free solder in order to form the connecting intermetallic layer. There is a distinct difference in the copper dissolution rates of the major alloys being considered wi

Hello Arnold, Just to clarify the Sn100C discussion: Please note that SN100C is the Nihon Superior alloy composed of tin/.7copper/nickel. The key point in regard to SN100C is that Cu does not go directly into solution but first reacts to form an inte

Does anyone know 2-pin DIP components? Who uses them, why are they in the DIP form and not simple axial components? Are they usually placed by hand or by modified DIP placement machines? Thanks for any answers, Erhard

JEDEC and IPC for instance do have conventions. But they are only typically for existing part types and do not coincide with one another. I think the bigger problem is the new components and the unusual components that don't seem to fall into any p

If you are talking about a DIP package Hepco (www.hepcoblue.com) is advertised on this site for lead forming equipment (they do have a DIP trimmer) and Bomir can be found elsewhere.

Looking to purchase a DIP lead forming tool. The tool that has the 2 rollers that let you place the DIP part on the rail and run it between 2 rollers (ball-bearing?). I found a place that once sold them. They were called an RS Pro IC Insertion Tool

Is there anyone performs solderability evaluation on PCB as a part of receiving acceptance criteria. It's costly to perform any form of physical evaluation whether simple as dip and look or wetting force balance. How do you have control in place to a
