WM-DDI Replacing chip components All chip components should be connected and disconnect- ed, using a tapered soldering iron [temperature of the iron tip: less than 280” C (536 F)] , a pair of tweezers and braid- ed wire. | Precautions for replacement 1. Do not disconnect the chip component forcefully. Otherwise, the pattern may peel off. . Never re-use a disconnected chip component. Dispose of all old chip components. . To protect the chip component, heating time for attach- ing the component should be within 3 seconds. O Removing chip components (1) Removing solder at electrode Remove the solder at the electrode, using a thin braided wire. Do not remove the solder of the part (chip component) attached adjacent to the electrode. Pattern Braided wire (2) Disconnecting chip components Turn the tweezers with the soldering iron alternately applied to both electrodes, and the chip component will be disconnected. Take careful precautions while disconnecting, because if the chip component is force- fully removed the land may peel off. Never re-use a disconnected chip component. Tweezers Turn (3) Smoothing the soldered surface After disconnecting the chip component, remove the solder by using a braided wire to smooth the land surface. O Connecting chip components The value of chip components is not displayed on the main body. Take due precautions to avoid mixing new chip components with other ones. (1) Applying solder to land on one side Apply a thin layer of solder to the land on one side where the chip component is to be connected. Too much solder may cause bridging. Small quantity of solder — (2) Speedy soldering Hold the chip component at the desired position, using tweezers, and apply the soldering iron in the arrow-marked direction. To protect the chip compo- nent, heating time should be within 3 seconds. Soldering iron = / 7 \ Land Printed circuit board (3) Speedy soldering of electrode on the other side Solder the electrode on the other side in the same way as in (2) above.
