Hi, Need to know if anybody has good reliability data on Sn/Bi component termination and Sn/Pb solder paste ? thanks GSW

You should see a coarse silverish / grayish coat on the termination that indicates that it soldered. We have to opinion [don't know] about the strength of solder connection versus the strength of component terminations.

Well take away the easy answers! How are the parts falling off? Is the joint breaking the termination on the part or is it breaking at the solder to termination interface? Also, how long are these parts in liquidous state? and what type of paste a

The solder adheres to the lands very well so i don't think that problem is with solderability of the PCB. Not wetting to the 0805 terminations. When the problem appeared with the 0805 we chenged the supplier. But there was commnon element Pb-free te

The issue may not be the solderability protection. It could be that the metalization on the component terminal or the metal of the component terminal was not prepared properly before the solderability protection was added.

Thank D.B. Cooper, actually this LED has 3 sides termination but no termination at underneath of LED. So this LED tends to float rather than performing solder joint during reflow process.

Chris As you imply, testing board and component solderability prior to assembly is preferred. * ANSI/J-STD-002 - Solderability Tests for Component Leads, Terminations, Lugs, Terminals, and Wires * ANSI/J-STD-003 - Solderability Tests for Printed Boa

Have you tested the solderability of the inbound components per ANSI/J-STD-002, Solderability Tests for Component Leads, Terminations, Lugs, Terminals, and Wires?

I observed some black dot or some oxidation occured on chip termination on pcba reflowed fews weeks ago as buffer stock. The solder joint and fillet wetting is good and shinning. It is an acceptable or defect condition per IPC standard/requirement? W
