During the repair of microcircuits, the computer's motherboard needs to be used. But it is not always easy to operate, because it is quickly overheated, there is no possibility to adjust the temperature. And then Mobile Improved Soldering Station is necessary. Do it yourself B. Her homework learned to create folk craftsmen.
One of the options is the creation of a soldering station that is placed in the power supply (more precisely, its body) from the soldering iron, sizes of eighty-fifty five five per sixty-five millimeters, with the ability to connect to it of old EPSN. To create a soldering station, it is required to purchase a resistive soldering iron with a heater, a resistive sensor and an additional wedge-shaft of 1.6 millimeters.
The EPSN is embedded with a thermocouple from the multimeter of Chinese production. The controller fee received the size of forty three to thirty-three millimeters. Portable digital soldering station, with their own hands collected, reports readiness for the work of the solderingry inscriptions on the display. After starting, the controller includes ACC and reads on the inputs PC0, PC1 voltage level. In the event that it is equal to the power voltage, it means that there are no solders, and "ERR" appears on the display, which reports error.
When the voltage on one of the inputs is less than 4.5 volts, then you can choose a soldering iron or resistive or thermocher. And for each, you can adjust the temperature using the keys. A flashing point appears on the display, which reports which of the devices is selected. The power of the soldering iron can be adjusted using the VT1 key modulation.
When the soldering station is going to do with her own hands, you can do without additional transistors, because at a current of 2 mA, an intensive and bright glow will be obtained. Cathodes are directly connected to the controller ports. The indicator is necessary to fall into the board with thin wires and secure it from its back side with thermoclause.
To place the buttons and the display, you must make holes in the front panel of the case. Drawing panels in a mirror image Print on a transparent film, stick a double-sided white tape from toner, trim around the perimeter of the pattern and then stick to the case. For convenience, it is better to glue the button to the panel using a thermal.
For installation work with large boards, such as the PC motherboard or laptops, the infrared soldering station will suit, with their own hands, it is also quite real. For soldering with surface installation of the printed circuit board and its components (for example, BGA), it is suitable for either hot air or infrared radiation.
The device itself consists of a control unit contained in a separate case. It has two heaters and fastening for boards. The upper position can be changed depending on the fixed board. The bottom heater serves a hardware for electric powder with a power of two kilowatts and a diameter of two hundred and twenty millimeters. The upper heater is four tubular halogen lamps. Each of them is 150 W. Thus, the soldering station, with their own hands assembled, acquires a finished look.
The tripod can be made from the rails from the matrix printer. The remaining details are also borrowed from the old computer technology. The indicator serves a 2-line liquid crystal module and controller. Instead of impulse transformers, it is better to use semistors and their radiators. It must be remembered that when they are installed, care is needed, as semi-stalkers are under voltage. In addition to these parts, it will take a power supply unit for a soldering station, providing a current on two channels, a keyboard, display, a sound signaling device and a zero detector.
If you have created a soldering station with your own hands, it is important to know some safety rules when working with it. For example, it is impossible to allow halogen lamps to be stained with fat. Therefore, they need to be carefully wiped with acetone or gasoline, and before starting work, put on safety glasses from the sun.
