This is composed of charging of cell phones, transmission and reception of data, ear jacks, microphones, and characteristically optimized circuits for each RF band, and is the PBA on which SMT parts are installed in the level of 70 to 90 points.
This is the PBA,composed of IrED for short distance recognition, usage environment recognition, iris recognition of cell phone users, and SVC LED circuit.
This is the process through which IC and CHIP parts are automatically installed on FPCB and PCB, and through which DoosungTech possesses high, middle, and low-speed lines tailored according to the customer needs and it produces SMT products for zero customer complaints.
PBA
This is the process through which option parts are assembled, including attaching tapes to the PBA on which SMT has been applied.
