Abstract:
A method for correcting or hammering a deformation which occurs in a multi-channel optoelectronic module and is caused by a post welding shift, wherein the multi-channel optoelectronic module has an optical fiber support member for supporting an optical fiber array, comprising the steps of:assembling the multi-channel optoelectronic module by using a laser welding process; andforming at least one welded portion on a predetermined position of said optical fiber supporting member corresponding to the deformation to thereby recover the deformation by using a shrinkage effect of the welded portion;wherein the predetermined position is determined in correspondence with all of deformations in x-, y- and z-axis direction and rotational directions Rx, Ry and Rz for each axis.
