1. ABOUT LEAD FREE SOLDER (PbF: Pb free) Note: In the information below, Pb, the symbol for lead in the periodic table of elements, will refer to standard solder or solder that contains lead. We will use PbF Solder when discussing the lead free solder used in our manufacturing process which is made from Tin (Sn), Silver (Ag), and Copper (Cu).
be sure that any remaining is melted prior to applying the Pb solder. - When applying PbF solder to double layered boards, please check the component side for excess which may flow onto the opposite side (See the figure below). 1.1.
ICs and LSIs are vulnerable to static electricity. When repairing, the following precautions will help prevent recurring malfunctions. 1. Cover the plastic parts boxes with aluminum foil. 2. Ground the soldering irons. 3. Use a conductive mat on the worktable. 4.

Note: Refer to Main (Flow Solder Side View) 12. CIRCUIT OPERATIONS 12.1. Telephone Line Interface and Pulse Dial Circuit When the hook switch SW1 is ON (off-hook), the circuit is closed, and current is supplied to the base of Q2 via the diode bridge D17 and Q2 is On Q1 is ON (OFF-HOOK condition).
wave. The signal flow to the line is as follows. Pin 25 of IC1 Tel Line. The DTMF signal is sent to the line via the following path. Q3 is an amplifier which is used to output the signal to line. Shown below is the signal flow used to output the DTMF signal from the handset as a monitor tone when a dial key is pressed.
Circuit Operation: The bell signal passes through C1 (R1) pin 21 of IC1 detect the bell signal. The ring signal is output from Pin 8 of IC1, and its volume is adjusted in 3 steps (H-L-OFF) by SW3 then impressed on the ceramic sound generator, and so is generated. R15, R16 .
14. HOW TO REPLACE FLAT PACKAGE IC 14.1. Preparation - PbF (: Pb free) Solder - Soldering Iron Tip Temperature of 700°F ± 20°F (370°C ± 10°C) Note: We recommend a 30 to 40 Watt soldering iron. An expert may be able to use a 60 to 80 Watt iron where someone with less experience could overheat and damage the PCB foil.
diagonally opposite pins in the correct positions on the PCB. Be certain each pin is located over the correct pad on the PCB. 2. Apply flux to all of the pins on the IC. 3. Being careful to not unsolder the tack points, slide the soldering iron along the tips of the pins while feeding enough solder to the tip so that it flows under the pins as they are heated.
