29,30 of this

terminal

25,26 is extended back when pin 33 with terminal 31 is separated, the pin though can stagger, yet produce the problem that is difficult to repair welding again, row's pin 33 is below

terminal

25,26 promptly, when wanting repair welding, need pass the gap of

terminal

25,26,, pass by slight gap like this and make repair welding difficulty very really because terminal 25, the 26 terminal gap after arranging together is very little.Because when the bonder terminal One's name is legion, the horizontal pin of each terminal can't be guaranteed 100% planarization naturally, so terminal board lists and need be designed to be easy to repair welding, so after electric connector is welded on motherboard, still can carry out repair welding again if find the pin failure welding of a certain terminal.
