Laser debridging of microelectronic solder joints
摘要:
A solder bridge between leads of a microelectronic circuit is removed by projecting a laser beam onto the solder bridge with sufficient power to cause the solder forming the bridge to melt and to flow onto a wicking tool placed into contact with the solder bridge. The wicking tool is removed during the heating to remove the solder and debridge the leads. Microelectronic leads having a width of the order of 4 mils and a pitch of the order of 8 mils may be debridged easily using the invention.
