13. Avoid accidentally getting solder in the connector Be careful not to form solder bridges between the connector pins Examine your work closely for shorts due to solder bridges Flexible Circuits The flexible circuits are made from a different material than the rigid boards and require different soldering techniques Excessive prolonged heat on a flexible circuit can damage the material Therefore avoid excessive heat and excessive bending For parts replacement use the ST 1087 Temperature Controlled Solder Station with a 600 700 degree F tip and use small diameter solder such as ST 633 The smaller size solder will melt faster and require less heat to be applied to the circuit To replace a component on a flexible circuit 1 Grasp with seizers hemostats the edge of the flexible circuit near the part to be removed 2 Pull gently 3 Apply the tip of the soldering iron to the component connections while pulling with the seizers NOTE Do not attempt to puddle out components Prolonged application of heat may damage the flexible circuit Chip Components Use either the RLN 4062 Hot Air Repair Station or the Motorola 0180381B45 Repair Station for chip component replacement When using the 0180381B45 Repair Station select the TJ 65 mini thermojet hand piece On either unit adjust the temperature control to 700 degrees F 370 degrees C and adjust the airflow to a minimum setting Airflow can vary due to component density
