7. Some chassis circuit boards have slotted holes oblong through which the IC leads are inserted and then bent flat against the circuit foil When holes are of slotted type the following technique should be used to remove and replace the IC When working with boards using the familiar round hole use the standard technique as outlined Removal Desolder and straighten each IC lead in one operation by gently prying up on the lead with the soldering iron tip as the solder melts Draw away the melted solder with an anti static suction type solder removal device or with solder braid before removing the IC Replacement Carefully insert the replacement IC in the circuit board Carefully bend each IC lead against the circuit foil pad and solder it Clean the soldered areas with a small wire bristle brush It is not necessary to reapply acrylic coating to the areas Small Signal Discrete Transistor Removal Replacement Remove the defective transistor by clipping its leads as close as possible to the component body Bend into a U shape the end of each of three leads remaining on the circuit board Bend into U shape the replacement transistor leads Connect the replacement transistor leads to the corresponding leads extending from the circuit board and crimp the U with long nose pliers to insure metal to metal contact then solder each connection Power Output Transistor Device Warning and Cautions Removal Replacement
