The second step, the casing, the original TV stick on theinfrared receiving tube, the antenna plug socket and USBremoved. (see Figure 3, figure 4, figure 5)

Using high-power iron, used method of bulk tin was soonremoved smoothly after completion, with alcohol to cleana small circuit board.

The third step, the installation of the USB socket, patch,electrolytic capacitors and other components. (see Figure 6, Figure 7, figure 8)

First with a small iron making pads of circuit board over a layer of solder, then put up USB socket. The circuit boardis very close to two small positioning hole, a positioning hole socket according to put good, its location is automatically a good place, and then dipped in a small iron rosin, basic can firmly fixed. On four fixed feet aftersolder, USB socket welding completed. According to thenumerical circuit board marked with small iron by welding,or the use of air heater one-time welding. Every kind ofSMD resistor capacitor will give a to prevent accidental loss.

The fourth step, with a diameter of 5mm bit and coiled coiltwo low pass filter. Around 8 laps. (see Figure 9, figure 10)

After the coil pin arrangement can be directly welded(polyurethane enamelled wire, direct welding enamelled wire).

Figure 10

The fifth step, making wideband high-frequency transformer. (see Figure 11, Figure 18)

The thin enamel with wire back and forth two is divided into three sections, the three section then smoothedtogether.

Put one bolt hanging in a small wire hooks, then the ironhook in the small drill head, slow start the drill to makethree enameled wires are twisted together, pay attention to control not twisted too deep. Then used a good three shares of enameled wire in the core to wear around 8 laps.

The sixth step, take the lead of the high frequency transformer is welded to the RTL2832's 4 feet and 5 feet.(see Figure 12, Figure 18)
This is indeed a careful technique to live, to use very fineiron welding head. Chip pin only a little, the lead of the high frequency transformer in advance good tin, solder a little residual online side, will head the alignment pin. The best pre on pins painted some sticky rosin paste, suchthreads on the pin, rosin paste will stick thin head fixedpoint. Then with a small iron head clean on punctualitycan be welded. Eyes not good can best help a magnifying glass observation and operation. Circuit board small light,easy to shift in welding, suggest using a small fixedwelding operation bench.
The seventh step, The intermediate TV circuit board are embedded in the big circuit board. (see Figure 12, figure 13)

After the circuit board aligned position in the frame, the solder in the four corners TV circuit board and ground connection circuit frame around the part can be fixed by ahigh-power iron accumulation. In the opposite position of the circuit board of the samepile of tin welding good grounding frame and four angle.

The eighth step, the high frequency transformer of the leads are welded on the circuit boards (see Figure 12,Figure 18)
