Electro Pcb Repair

IPM is the most important part of inverter-based things such as inverter air-condition, Refrigerator, Moter drive, On-grid solar inverter, Three-phase inverter, etc. IPM (Intelligent Power Module ) is a high-performance module that mounts a dedicated drive circuit for drawing greater performance from an IGBT chip, and it provides a custom IC IPM is a combination of IGBT    and bridge drive chip which is a vital compact electronics part for every compact thing like BLDC motors that are mostly used in all kinds of Refrigerators and Air conditioners. there are a lot of pins put on the Ipm and these pins assigned the various type of work such as Dc input voltage, AC output voltage, Input signal voltage, sensors signals, etc.

PCB-Printed Circuit Board. PCB mainly consists of Microcontroller which we can say that it is the brain of the circuit without this the circuit is incomplete. Microcontroller and other components of PCB combine forms a Circuit in which Microcontroller operates all functions. The Microcontroller (mn101ef31gxw) is a programmable IC(Integrated Circuit) which can be programmed to operate any kind of machine. One more IC called EEPROM(24c04) also works with it.  Other than these PCB need power like 5volt to operate microcontroller and 12volt for other components like Relay, etc.  Mostly the problem that comes in LG Air Conditioner PCB is power supply related. The SMPS power supply becomes faulty due to fluctuation of light and other some reasons.  Other than this power supply problem, the EEPROM IC problem also comes in the PCB. Due to this IC problem, sometimes it does not ERROR on display and the PCB also not works. When the IC becomes faulty, then the technician also faces ...
