Went to Biyagama export processing zone to obtain PCBs. The PCBs were for the sewing machine automation project for MAS. The company which made the PCBs was TOS lanka. They uses high tech equipments such as robotic hands to solder equipments to the PCBs. But the PCBs were not complete we have to do some own soldering according to our needs. I assembled potentiometers, rotary switches Leds, oled displays and switches to the front panel. I met with some officials of TOS lanka company (pvt) LTD It was a great experience to meet some professionals in PCB manufacturing industry in Sri Lanka.
