Teka Interconnection Systems can supply .025" pins as an assembly with
solder and flux pre-deposited allowing you to insert the pins from the
circuit side go right to chip shooter and then reflow without flipping the
PCB or adding solder paste. For more information contact me offline and/or
go to http://www.tekais.com
