A JIG FOR TESTING THE PRINTED CIRCUIT BOARDS (10) UTILIZES THE ADJUSTABLE GUIDE MEMBERS (600) TO EASILY POSITION DIFFERENT SIZES OF CIRCUIT BOARDS ON A WORKING PLATE (400), WHEREIN THE WORKING PLATE CAN SMOOTHLY SLIDE UP AND DOWN ALONG THE GUIDE COLUMNS (500) AND THE ELASTIC MEMBERS (212S) WITHOUT JAMMING. THE SECOND SURFACE (410U) OF THE WORKING PLATE IS FORMED WITH A CONCAVITY (420) AND SEVERAL BULGED SECTIONS (420B) TO STABLY PLACE THE CIRCUIT BOARD WITHOUT DEFORMATION, AND THEREFORE THE SOLDERING POINTS OF THE CIRCUIT BOARD CAN UNIFORMLY TOUCH THE TIPS (T) OF THE PROBES (213P) WHICH ARE RETRACTABLY INSTALLED IN THE THROUGH HOLES (213) OF THE BASE (200). BY USING THE ASSEMBLING BASE (200,300), THE MAINTENANCE OF THE INTERNAL STRUCTURE OF THE BASE CAN BE IMPROVED.
