PCB WIRE LAYOUT SCHEMATIC
Transmitting tube output ground line
The transmitting tube ground line and IC ground line should layout separated or overstriking ground line.
The above IC only use to hint, not to specified. Note: * In wire layout, the power filter capacitor should near to IC. * In wire layout, should avoid power line and ground line too long. * Recommended infrared transmit unit and IC ground line should layout separated, or over striking lines. * The emitter of triode connect 1 resistor at least. * Recommended triode use 9014.

HANDLING MOS DEVICES:
Electrostatic charges can exist in many things. All of our MOS devices are internally protected against electrostatic discharge but they can be damaged if the following precautions are not taken: * Persons at a work bench should be earthed via a wrist strap. * Equipment cases should be earthed. * All tools used during assembly, including soldering tools and solder baths, must be earthed. * MOS devices should be packed for dispatch in antistatic/conductive containers. Note: IC oscillator input mustn't be on the outside layer, thus to avoid the abnormal working when human body touches the remote controller without crust in testing.
