Emmanuel: Take Jax's word. NiAu (ENIG) primary (some would say only) redeeming characteristic is its flatness that you mentioned, but that flatness appeals to folk placing fine pitch devices, rather than BGA. Good luck. Dave F

PC and Erico: Are yinns talking: 1 A component that will not lie flat on the board? 2 A component that will lie flat to the board that you can't get to solder to the pad? 3 A pad that is no longer attached to the board? 4 Something else. Whazit?

Run a DTI over the X and Y edges of the table to ensure that your XY table is flat, adjust the four small screws to suit. Also check that the Z cams are not worn and that the Z cam followers are not siezed or worn(they are prone to flat spots when wo

Okay....we're all familiar with "J" leads and "Gull wing" leads on SMT components.....can anyone elighten me on what a "flat ribbon" lead is?? Can you supply a picture? Thanks in advance.

Don't have a picture but a ribbon lead is jaust a flat lead with no standoff capability. look at a SMT electrolytic cap for this lead type.

If we received heatsinks with blisters on the contact surface, like you describe, we'd reject them. We want that surface to be perfectly flat. Google "heatsink flatness" for more. For instance: http://www.heatsink-guide.com/content.php?content=hea

For volume we used machined pocket durastone pallets, machined to the thickness of the flex to allow flat printing, with pockets machined for components placed on side 1. We held them down with 3M spray mount. For low volumes we used flat durastone

Flat surface is the number one choice for fresh part soldering. We did not discuss details about resistor size and location, but to keep them flat I will suggest no apertures on the stencil.

Flatness is only half of the advantage. Gold doesn't corrode. There are other flat surfaces but do not last as long as gold.
