How Can Printed Circuit Board Be Repaired
Tin can aircon circuit board (PCB) be repaired?
The advancement in air-conditioning technology has resulted in designs that enable superior energy saving ability and improved operation of the air conditioner. Old technology utilises electric components to perform direct control functioning of motors and compressor. This results in unoptimized operation that leads to higher free energy consumption.
Recent technology introduces optimized control that enables the aircon to adapt operation accordingly to the required cooling load. This control allows lower energy consumption. The new technology uses printed circuit board to perform complex communication, data calculation and output functioning.
The circuit board and its components, similar whatever other parts in the air-conditioning system, are subject to lifespan exhaustion also as damage. We shall briefly discuss the common breakdown scenarios:
- An air conditioner excursion lath operate in both voltage AC and DC voltages. Whenever there is a current surge, the circuitry may exist damaged by sudden introduction of higher voltage that is beyond its operating range.
- Inputting of wrong voltage into aircon circuit board by an inexperienced technician during installation can as well damage the board.
- Damage or shorted field wiring is another cause of circuit lath harm. Shorted or harm wire also results in incorrect or excessive introduction of voltage.
- Pests similar lizard or cockroaches that dwell inside the aircon circuit board may cause damage. Their bodies,when in direct wire contact, results in short circuitry of the electronics component.
A damaged aircon circuit board can normally be repaired merely this requires a well trained technical personnel to do it. Nonetheless virtually circuit boards can't be repaired on site. Proper repairing of circuit boards should be carried out in a workshop environs where all test equipments are readily bachelor. Upon repair, excursion board operation must be tested for a menstruum of time to determine if its operational over again.
Many aircon companies lack the above expertise, hence they recommend replacement of a new excursion board. Replacement cost for a new circuit board may double or triple the price of repair. Ironically , a new circuit lath is however bailiwick to the aforementioned damage as discussed above. Having said the above, some excursion lath may be so badly damaged that its beyond economical repair. Our workshop will perform a detailed assessment and advise our customer on the all-time options available.
AireControl provides circuit lath repair services and have successfully repaired several of boards from different manufacturers. Nosotros also offer such repair services to other air conditioning contractors who seek our repair services.
