Combined substitution
The combination substitution method involves reassembling the undamaged circuit sections of multiple ICs of the same model into a single complete IC, which can then replace the malfunctioning IC. This method is particularly suitable when the original IC is unavailable. However, it requires that the intact circuits within the ICs must have interface pins.
It's crucial to verify the basic electrical parameters, internal equivalent circuits, pin functions, and connection relationships between the ICs for indirect substitution. Be mindful of these during actual operations:
(1) Ensure the numbering sequence of the integrated circuit pins is correct; do not connect them incorrectly.
⑵ To accommodate the characteristics of the IC after substitution, the components of the peripheral circuit connected to it must be correspondingly modified.
The power voltage must match the replacement IC; if the original circuit's power voltage is high, efforts should be made to reduce it; if it's low, check if the replacement IC can operate.
After substitution, measure the IC's static operating current. If the current is significantly higher than the normal value, it indicates that the circuit may be self-oscillating, and decoupling and adjustment are required. If there is a difference in gain compared to before, adjust the feedback resistor value.
The input and output impedance of the replaced IC must match the original circuit; check its driving capability.
Utilize the existing foot holes and leads on the original circuit board during modifications. External leads should be neatly arranged, avoiding crossing in front and back, to facilitate inspection and prevent circuit oscillation, especially high-frequency oscillation.
[7] Before powering on, connect a DC ammeter in series with the Vcc power loop. Observe the change in the total current of the integrated circuit as the resistance value of the voltage-dropping resistor decreases.
