Abstract: Disclosed is a fastening plate for fastening a badge, comprising a fastening member (20) which fixedly fastens a badge to clothing by fixing a fixing part of the badge which passes through the clothing and further comprising a fastening plate (30) which is fixed to the fastening member (20), wherein the fastening plate (30) comprises: an adhering part (32) which adheres to the rear surface (41) of the clothing (40) having a badge (10) to be put on the front surface (42) thereof, and has a fixing hole (31) through which a fixing part (11) passes, the fixing part (11) penetrating from the front surface (42) of the clothing (40) to the rear surface (41) of the clothing; a plurality of cut holes (33) which are formed in the inner periphery thereof; and a plurality of wedges (34) which are folded upwards from the plurality of cut holes (33) and stand on the adhering part (32) so as to be inserted into the clothing (40) to which the adhering part (32) adheres.

Abstract: Disclosed is an aqueous alloy plating solution for surface treatment of a modular PCB. The plating solution comprises 1-30 wt % of an organic acid having at least one sulfonic acid group (—SO3H), 0.1-20 wt % of a complexing agent, 0.1-15 wt % of a thio-compound having at least one —S—, 0.05-5 wt % of a water soluble gold compound, 0.001-1 wt % of a water soluble silver compound and 0.1-10 wt % of a sequestering agent, based upon the weight of the plating solution. According to this invention, all plating properties required for the modular PCB are obtained through a single plating process, instead of the conventional double plating process.
