Mini radio principle circuit
Installation points: 1. Try to close to the circuit board when you are installing the components, and choose the correct vertical and horizontal installation way. 2. The welding time is less than 3 seconds, the special attention should be paid to the earplugs socket, ceramics capacitor, variable capacitor and switch to prevent damage. 3. Take or put the iron coil carefully to prevent the thrum abruptment. You need to remove the paint and add the tin before welding, and the components is fixed by the wax or double-sided adhesive after welding. 4. Try to install the earplugs socket near the lateral, and the installation is flat and exact. 5. The switch installation is flat and exact too. 6. The replacement of the transistor and integrated circuit don't make mistakes, also the pin. 7. You should pay attention to the tin absorption of the printing plate and the electric soldering iron head. Use the rosin reasonablly and avoid the virtual welding, false welding phenomenons. 8. Avoid using too many tin, the contact position of the electric soldering iron head and the circuit board must be accurately. Welding resistance components: R1: 100kΩ, color ring: brown black goldR2: about 1.5kΩ, color ring: palm green red goldR3: 33kΩ, color ring: orange orange orange goldR4: 2.7kΩ, color ring: red purple red goldR5: 39Ω, color ring: orange white blackR6: 39Ω, color ring: orange white black (View)

Bipolar reversed circuit diagram composed of ISO100

Published:2011/5/10 20:58:00 Author:Ecco | Keyword: Bipolar , reversed

Bipolar reversed circuit diagram composed of ISO100 is shown as the chart. Comparing with unipolar reversed circuit, the connection method of pin 16 and pin 8 in bipolar reversed circuit is different. In bipolar reversed circuit, pin 16 and pin 15 are connected, pin 8 and pin 7 are connected, the other requirements are same to unipolar reversed circuit. (View)
